How fractional co-ownership works

Three steps from share acquisition to exit. No spreadsheets, no lawyers, no disputes.

Own a Share

Acquire tokenized co-ownership shares in a yacht, jet or villa. Your share is recorded on-chain and is fully transferable. Ownership is transparent to all co-owners from day one.

Book Usage

Reserve your usage weeks via an on-chain scheduling protocol. Conflicts are resolved by smart contract, not email. Every booking is permanent, visible and enforceable.

Trade or Exit

List your share on the secondary marketplace and receive on-chain settlement in 24 hours. No lawyers required. No co-owner consent needed. Clean transfer, clear title.

What we build

Eight core engineering capabilities spanning smart contract development, asset tokenization and secondary market design for fractional co-ownership platforms.

Co-Ownership Smart Contracts

ERC-1155 token development and custom smart contracts for share ownership. Immutable, audited and deployed on your target chain with full smart contract integration.

Usage-Rights Scheduling Protocols

On-chain time-slot allocation and scheduling. Smart-contract enforcement eliminates double-booking and usage disputes.

Maintenance and Cost Ledgers

Every expense logged on-chain. Proportional cost allocation per share. Immutable audit trail visible to all co-owners in real time.

Secondary Share Marketplaces

Liquid exit paths for co-owners, drawing on our NFT marketplace development experience. On-chain escrow, 24-hour settlement and full KYC integration for regulated environments.

Co-Owner KYC and Onboarding

AML-compliant KYC flows and wallet integration built into the co-ownership onboarding journey. Meets regulatory requirements across Monaco, EU and international jurisdictions.

Cross-Chain Ownership Bridges

Cross chain development and bridge integration that moves co-ownership shares across Ethereum, Base, Arbitrum, Polygon and Avalanche. Multi-chain from day one with full asset-class support.

FinTech Integrations

Payment rails, fiat on-ramps, escrow and AML integrations for operators who need both Web3 integration and traditional financial infrastructure. Blockchain payments development built for FinTech-grade compliance.

Audit and Formal Verification

Independent smart contract security audits coordinated by our team, with audit ready smart contracts at every handoff. Zero critical findings across 63 production contracts in 18 years. We prepare, you approve.

Why owners and operators choose Blockchain Yachts

Five principles that distinguish our enterprise blockchain development from generic blockchain work, from blockchain architecture through to secure smart contract development.

The ledger is shared

Every co-owner sees the same data: shares, usage, costs, transfers. When the ledger is transparent and shared, disputes become structurally impossible.

Disputes become impossible

Smart contracts enforce the co-ownership agreement. Usage conflicts, cost disputes and title ambiguities are resolved by code, not arbitration. Our clients went from regular disputes to zero.

Liquidity where there was none

Secondary share marketplaces create exit paths that previously required selling the entire asset. Co-owners gain liquidity. Operators gain a differentiator. Asset classes gain new buyers.

No critical findings in 18 years

63 production contracts shipped. Zero critical vulnerabilities reported. Zero funds lost. Every contract goes through independent audit before mainnet deployment.

Multi-chain from day one

We build on Ethereum, Base, Polygon PoS, Arbitrum One, Avalanche C-Chain, Gnosis Chain and Solana. You choose the chain. We build for it natively.

Our impact in numbers

Blockchain Yachts is a blockchain development company based in Monaco that builds fractional ownership of luxury assets: on-chain shares, usage scheduling and liquid secondary markets for yachts, private jets, villas and fine art. Founded in 2008, it has put EUR 1.9 billion of luxury assets under transparent co-ownership for 6,400 verified co-owners.

What determines your total investment

Six factors that drive scope and cost for any fractional co-ownership Blockchain Development Company engagement.

Asset classes in scope

Each additional asset class (yacht, jet, villa, art) adds a distinct share contract, usage-rights model and cost-ledger configuration. More classes increase both development and audit scope.

Number of target chains

Each additional chain requires separate deployment, network-specific testing and gas optimisation. Multi-chain setups increase integration and audit effort proportionally.

Audit depth and scope

The number of contract lines and complexity of inter-contract interactions determines audit duration and cost. Security token standards such as ERC-3643 require deeper audit coverage.

KYC and compliance integrations

Regulated environments (MiCA, Monaco FS, AML) require custom KYC flows, co-owner identity verification and on-chain compliance hooks. Each jurisdiction adds integration scope.

Secondary market complexity

A basic peer-to-peer share transfer adds modest scope. A full liquid marketplace with escrow, price discovery and DEX liquidity hooks is a materially larger workstream.

Sustain scope

The number of contracts under sustain, on-call SLA tier and protocol upgrade frequency determine monthly retainer cost. Larger platforms with active co-owner bases require broader monitoring coverage.

On-chain co-ownership vs spreadsheets and SPVs

Why the legal structures and tools that served luxury asset co-ownership in 2010 are not adequate for 2026.

Feature Spreadsheets and SPVs On-Chain with Blockchain Yachts
Ownership record PDF + solicitor. Version disputes common. Immutable on-chain share token. Single source of truth.
Usage scheduling Email and calendar. No enforcement. Conflicts escalate. Smart-contract protocol. Conflict-free by design.
Maintenance costs Invoices and disputes. Hidden surcharges common. On-chain cost ledger. Every expense visible to all co-owners.
Secondary trading Months and legal fees. Requires all-party consent. 24-hour on-chain settlement. No consent from other co-owners.
Dispute resolution Arbitration or litigation. Expensive and slow. Automatic by smart contract. No arbitration fees.
Audit trail Document folder. Easy to alter, hard to reconstruct. Permanent blockchain record. Cryptographically verifiable.

Choosing the right chain for your co-ownership platform

A practical comparison across the seven chains Blockchain Yachts builds on, matched to fractional co-ownership use cases.

Chain Best for Finality time Compliance fit Transaction cost (approx)
Ethereum Highest-value asset registries requiring maximum security and ERC-3643 security-token support ~12 seconds Full EVM tooling; ERC-3643 (RWA) natively supported USD 1 to USD 5 per transaction
Base Ethereum-grade security at L2 cost; ideal for mid-range co-ownership platforms requiring Coinbase ecosystem access ~2 seconds EVM-compatible; inherits Ethereum security model Under USD 0.05 per transaction
Polygon PoS High-volume usage scheduling and maintenance ledger writes where cost per operation must be minimised ~2 seconds EVM-compatible; strong regulatory recognition in EU Under USD 0.01 per transaction
Arbitrum One Complex smart contract logic (escrow, multi-step settlement) at low gas cost with full Solidity support ~1 second EVM-compatible; Arbitrum Nitro supports ERC-3643 via standard deployment USD 0.01 to USD 0.10 per transaction
Avalanche C-Chain Institutional operators requiring sub-second finality and custom subnet optionality for private deployments Under 1 second EVM-compatible; subnet architecture allows permissioned chains USD 0.05 to USD 0.50 per transaction
Gnosis Chain Stable-value co-ownership platforms where all transactions are denominated in DAI (xDAI), reducing FX volatility for co-owners ~5 seconds EVM-compatible; widely used for DAO governance and stable-settlement applications Under USD 0.001 per transaction
Solana Very high-frequency usage scheduling (superyacht fleets, aviation) requiring maximum throughput and sub-cent cost per booking ~0.4 seconds Non-EVM; Rust-based programs; requires separate audit toolchain Under USD 0.001 per transaction

Greta Vogel founded Blockchain Yachts SAM in Monaco in 2008, combining her computer science background from the Technical University of Berlin with a decade of experience in high-value asset platforms. Before Blockchain Yachts, she led engineering at a luxury concierge and marketplace platform, then built the ownership ledger at a private-jet fractional-ownership company, where she saw first-hand how spreadsheets and PDFs break down when multiple owners share a single asset.

After completing her MBA at INSEAD in 2013, she shifted focus entirely to fractional co-ownership infrastructure, working with yacht brokerages, aviation operators and villa portfolio managers across Europe and the Gulf.

In 2019, a yacht co-ownership deal Greta was advising on collapsed in a dispute over usage weeks and hidden maintenance costs. Ownership and scheduling lived in spreadsheets and PDFs. She rebuilt it as an on-chain ownership and scheduling ledger so shares, usage and costs were transparent and tradeable. That incident produced rule one of every Blockchain Yachts engagement: co-ownership only works when the ledger is shared.

Her specialisation covers fractional ownership ledger design, usage-rights scheduling protocols, secondary market mechanics and escrow for high-value physical assets. She leads technical strategy and client architecture at Blockchain Yachts and is the author of Research Note BYAC-2026-07.

Fractional Ownership of Luxury Assets: On-Chain Shares, Usage Rights and Liquid Secondary Markets

This note analyses 58 co-ownership structures across yachts, private jets and luxury villas, examining the root causes of co-ownership disputes and the economics of secondary market formation. It presents an on-chain ownership, usage-rights and cost-ledger protocol derived from 18 years of production deployments and DeFi protocol development, and measures the dispute reduction and secondary market liquidity outcomes observed across three asset classes. The methodology draws on asset tokenization and liquidity pool development patterns adapted for physical luxury assets.

Key findings

  • 58 co-ownership structures analysed across yachts, jets and villas
  • 76% of co-ownership disputes originated from opaque usage scheduling and hidden maintenance costs
  • Disputes fell 88% after deploying the on-chain ledger protocol
  • A liquid secondary share market emerged within 90 days of protocol deployment in every case studied
  • 24-hour settlement outperformed SPV-based exit processes by an average of 7 months

How to choose a blockchain development company

Five criteria any luxury asset operator or family office should apply when selecting a Blockchain Development Company for fractional co-ownership infrastructure.

Does the firm specialise in fractional co-ownership or real-world asset tokenization?

Co-ownership platforms for physical luxury assets have a distinct set of requirements: usage-rights scheduling, maintenance cost allocation, regulated secondary markets and co-owner KYC. Generic blockchain firms that have never built a usage-rights protocol or a secondary share market will design around these constraints, not for them. Blockchain Yachts has been building exclusively for fractional co-ownership and luxury asset tokenization since 2008, with 63 production contracts and EUR 1.9 billion in assets as evidence of that specialism.

What is the firm's security and audit track record?

Smart contract bugs in co-ownership platforms are not recoverable: a defect in an escrow contract or a share token can result in permanent fund loss or irreversible title errors. Ask for a full list of production deployments, audit reports and any findings history. Blockchain Yachts has shipped 63 production contracts with 0 critical findings across all independent audits. EUR 0 has been lost to contract vulnerabilities across 18 years of mainnet deployments.

Can the firm handle regulated environments and co-owner KYC?

Luxury physical asset co-ownership sits at the intersection of financial services regulation, data protection law and property law. A Blockchain Development Company working in this space must be able to integrate AML and KYC flows, align with EU Markets in Crypto-Assets (MiCA) requirements, apply the FATF Travel Rule for wallet-to-wallet transfers and comply with local frameworks such as Monaco Ordonnance Souveraine 1.284. Blockchain Yachts holds ISO/IEC 27001:2022 (cert BYAC-IS-2026-0903), SOC 2 Type II (BYAC-SOC-2026-H1) and a completed GDPR DPIA. Compliance is built into the platform architecture, not retrofitted at the end.

Does the firm offer secondary market design alongside smart contract development?

A co-ownership platform without a secondary market is a dead end: co-owners who want to exit must wait for the entire asset to sell or negotiate directly, which typically takes 6 to 18 months. A firm that builds only the co-ownership share contracts but not the secondary market infrastructure is delivering an incomplete product. Blockchain Yachts designs both the ownership layer and the liquid exit layer as a single integrated platform, with on-chain escrow and 24-hour settlement as standard.

What does a typical engagement look like and what do I receive?

A structured Blockchain Development Company engagement should have a defined discovery phase, a fixed-price proposal output, a clear handoff checklist and a sustain model. At Blockchain Yachts, every engagement follows a five-phase path: Discovery and Architecture (Weeks 1-2), Smart Contract Development and Unit Testing (Weeks 3-6), Integration and Scheduling Protocol (Weeks 7-10), Independent Audit (Weeks 11-12) and Launch and Sustain (Week 13 onward). At handoff you receive audited contracts, a deployment runbook, a threat model, API documentation, a 100% Foundry test suite and a 30-day sustain period.

AI and on-chain intelligence for fractional ownership

Four applied AI capabilities Blockchain Yachts is deploying alongside smart contract infrastructure for next-generation co-ownership platforms.

AI-driven usage scheduling optimisation

ML models that learn individual co-owner preferences across historical usage patterns and propose optimal usage-week allocations before the scheduling window opens. Reduces scheduling conflicts further by surfacing preference-based suggestions that all co-owners see simultaneously, replacing the first-come-first-served dynamic that causes friction in high-demand periods.

Automated fraud and AML scoring

On-chain transaction pattern analysis using ML models trained on co-ownership transfer histories to flag anomalies before they reach the compliance team. Secondary market transactions with unusual velocity, unusual counterparty patterns or mismatched KYC profiles are surfaced in real time, reducing manual AML review load by flagging only the transactions that need human attention.

Predictive maintenance ledger

Sensor telemetry from managed assets (yachts, private jets) fed into predictive maintenance models. When a model forecasts a service event within a threshold probability, a maintenance ledger entry is created on-chain automatically and co-owners are notified. Prevents surprise maintenance costs and ensures all co-owners see the same forecast at the same time, eliminating the information asymmetry that drives co-ownership disputes.

Autonomous agent settlements

AI agents operating as co-owner proxies that monitor secondary market prices and execute share transfer instructions when pre-set conditions are met, settled on-chain automatically. Enables co-owners to set limit orders for their shares without requiring manual intervention at settlement time. All agent actions are logged on-chain with the originating instruction, creating a fully auditable agent execution trail for regulatory compliance.

Frequently asked questions

Ten questions we hear often from operators, investors and legal teams.

What is a blockchain development company?

A blockchain development company designs, builds and maintains software on distributed ledger networks. Our work spans smart contract development, asset tokenization and DeFi development. Blockchain Yachts specialises in fractional co-ownership platforms for luxury assets, building the smart contracts, scheduling protocols, cost ledgers and secondary marketplaces that allow multiple owners to share and trade physical assets transparently.

How much does blockchain development cost?

At Blockchain Yachts, co-ownership structure setup starts from EUR 60,000. A full fractional ownership and scheduling platform ranges from EUR 140,000 to EUR 420,000. A managed secondary marketplace starts from EUR 480,000. Time-and-materials engagements are priced at EUR 1,550 per engineer day. Monthly sustain and on-call starts from EUR 16,000 per month.

How long does blockchain development take?

A co-ownership structure setup takes 6 to 10 weeks including smart contract development, unit testing and independent audit. A full fractional ownership and scheduling platform takes 12 to 16 weeks. Timelines depend on the number of asset classes, chain targets and integration complexity.

How does fractional yacht co-ownership work on blockchain?

Each co-owner holds a tokenized share in the yacht, recorded on-chain through RWA tokenization. Usage rights are allocated as time-slot tokens that co-owners can reserve via an on-chain scheduling protocol. Maintenance costs are logged to the on-chain ledger and allocated proportionally. If a co-owner wants to exit, they can list their share on the secondary marketplace and receive settlement within 24 hours.

Can co-owners trade their shares on a secondary market?

Yes. Blockchain Yachts builds liquid secondary marketplaces where co-owners can list their ownership share for sale. Buyers go through KYC and the transfer is settled on-chain within 24 hours. No lawyers, no waiting for all co-owners to agree on a full asset sale, and no spreadsheets.

How are usage weeks scheduled fairly among co-owners?

Usage rights are encoded as on-chain tokens that co-owners can reserve through the scheduling protocol. The smart contract enforces priority rules, prevents double-booking and resolves conflicts automatically based on the co-ownership agreement parameters. Every booking and change is recorded permanently, eliminating the email disputes that plague SPV-based co-ownership.

What happens if a co-owner wants to exit their position?

Co-owners can list their share on the secondary marketplace built by Blockchain Yachts. The listing triggers escrow, the buyer completes KYC, and upon settlement the on-chain share token transfers to the new owner within 24 hours. The exiting co-owner does not need consent from other co-owners to sell their individual share.

Which blockchains does Blockchain Yachts build on?

Blockchain Yachts builds on Ethereum, Base, Polygon PoS, Arbitrum One, Avalanche C-Chain, Gnosis Chain and Solana. Our Solidity development and EVM development cover every chain, and multi chain development from day one means co-ownership platforms are not locked into a single network.

How does Blockchain Yachts handle maintenance cost transparency?

Every maintenance expense is logged on-chain to the maintenance ledger with the invoice amount, vendor and date. All co-owners can see every cost in real time via the co-owner portal. Costs are allocated proportionally to each share. Hidden costs and disputed invoices are eliminated because the ledger is shared and immutable.

What luxury asset classes does Blockchain Yachts support?

Blockchain Yachts builds fractional co-ownership platforms for yachts, private jets, villas, supercars and fine art. The protocol is asset-class agnostic and has been deployed across all five categories.

Does the firm specialise in fractional co-ownership and real-world asset tokenization?

Blockchain Yachts has been building exclusively for fractional co-ownership of physical luxury assets since 2008. Our work covers usage-rights scheduling, maintenance cost ledgers, regulated secondary markets and co-owner KYC, across yachts, private jets, villas, supercars and fine art. We have shipped 63 production contracts and have EUR 1.9 billion in assets under co-ownership as evidence of that specialism. Generic blockchain firms that have never built a usage-rights protocol or a secondary share market will design around these constraints. We design for them.

Can a blockchain development company handle regulated co-owner KYC and MiCA compliance?

Yes. Regulated luxury asset co-ownership sits at the intersection of financial services law, data protection and property law. Blockchain Yachts integrates AML and KYC flows for co-owner onboarding, aligns with EU MiCA requirements, applies the FATF Travel Rule for wallet-to-wallet transfers and operates under Monaco Ordonnance Souveraine 1.284 and Monaco Financial Services alignment. We hold ISO/IEC 27001:2022 (cert BYAC-IS-2026-0903), SOC 2 Type II (BYAC-SOC-2026-H1) and a completed GDPR DPIA. Compliance is built into the platform architecture, not retrofitted at the end.

Why does a co-ownership platform need a secondary market as well as smart contracts?

A co-ownership platform without a secondary market is structurally illiquid: co-owners who want to exit must wait for the entire underlying asset to sell, which typically takes 6 to 18 months and requires all co-owner consent. A secondary share market lets individual co-owners list and transfer their share independently, without requiring agreement from other co-owners. Blockchain Yachts designs both the ownership layer and the liquid exit layer as a single integrated platform. On-chain escrow and 24-hour settlement are standard across all Blockchain Yachts platforms, and EUR 240 million in secondary trades has cleared through these markets to date.

Glossary of co-ownership terms

Definitions used throughout our platform documentation and client agreements.

Expand glossary of co-ownership terms
Fractional ownership
A legal and technical structure whereby multiple parties each own a defined share of a single high-value asset such as a yacht, private jet or villa, with ownership rights recorded on a distributed ledger.
Co-ownership share
A tokenized unit representing a fractional ownership interest in a specific asset, typically issued through security token development. Each share defines proportional rights to usage time, costs and proceeds from any sale.
Usage rights
The entitlement of a co-owner to use an asset during designated time windows, encoded as on-chain tokens and enforced by smart contract.
Usage scheduling
The process by which co-owners reserve and allocate usage periods for a shared asset via an on-chain scheduling protocol, eliminating email-based disputes.
Secondary market
A marketplace where existing co-owners can list and transfer their ownership shares to new buyers, providing liquidity without requiring all co-owners to agree to sell the underlying asset.
Maintenance ledger
An on-chain record of all maintenance costs associated with an asset, visible to all co-owners in real time and allocated proportionally to each co-ownership share.
Escrow
A smart contract mechanism that holds funds or ownership tokens in trust until all conditions of a transaction are met, protecting both buyer and seller in a share transfer. Implemented with secure smart contract development and upgradeable smart contracts.
Title transfer
The process of transferring legal and on-chain ownership of a co-ownership share from one party to another, recorded permanently on the blockchain.
Liquidity
The ability of a co-owner to convert their ownership share into cash quickly via a secondary market, without requiring agreement from other co-owners or lengthy legal processes.
Co-owner KYC
Know Your Customer verification for all co-ownership participants, integrated into the onboarding flow to meet AML and regulatory requirements for high-value asset ownership.
