ENTERPRISE-GRADE SECURITY
Business Outcomes: Why Secure Custody is Critical
Fractionalizing high-value assets introduces unique risks. Our custody and escrow service is engineered to mitigate them, delivering tangible business results for your platform and its users.
01
Eliminate Single Points of Failure
Multi-signature MPC wallets and geographically distributed key sharding ensure no single entity can compromise the underlying NFT asset. This institutional-grade custody model is a prerequisite for attracting serious capital.

02
Guarantee Asset Integrity & Provenance
Every fractional token is backed 1:1 by the original NFT, held in a transparent, on-chain escrow contract. Real-time proof-of-reserves provides verifiable assurance to all token holders, building foundational trust.

Frequently Asked Questions on NFT Custody & Escrow
Get clear, specific answers on how our fractional NFT custody and escrow service works, from security to deployment.
A standard deployment for a custom fractional NFT vault with escrow logic takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your frontend, security audit, and testnet deployment. Complex multi-chain or heavily customized governance features may extend this to 6-8 weeks.
