Unvault Marketplace
A New Marketplace is on the Blockchain
More than a listing interface. An integrated NFT marketplace built to support cross-chain listings and royalties.
Unvault is built to solve two structural problems in NFTs: cross-chain fragmentation and royalty avoidance. It is a cross-chain NFT mobility protocol designed around a vault-and-claim architecture that preserves identity, ownership, and economic logic as assets move between chains.
When an NFT moves from one blockchain to another, it is not duplicated, wrapped, or synthetically bridged. Instead, the original NFT is locked in a smart contract vault on the origin chain. A canonical representation becomes claimable on the destination chain, while the original token remains non-circulating for the duration of that claim.
This structure preserves ownership continuity and verifiable provenance. Unvault is not a wrapper and not a conventional bridge. It is an identity-preserving mobility layer for NFTs.
Vault Across Multiple Chains
Move your NFTs freely while preserving identity, provenance, and royalties.
Lock on Origin
Original NFT is locked in a smart contract vault on the source chain. Token becomes non-circulating but ownership is preserved.
Claim on Destination
Canonical representation becomes claimable on the destination chain. Full utility and logic intact.
Return Anytime
Owner can return the NFT to origin chain. Original asset unlocked, destination representation is vaulted.
Cross-Chain Listings
List your NFT on any supported chain without losing ownership continuity.
List Anywhere, Trade Everywhere
NFT listed on Ethereum? Buyers can purchase and transfer to ApeChain, Base, or any supported chain.
Single Source of Truth
Only one canonical asset exists. No liquidity fragmentation across wrapped versions.
Provenance Preserved
Full on-chain history maintained. Original contract and token ID always verifiable.
Cross-Chain Mints
Historically, “cross-chain mints” meant splitting a collection — minting on multiple chains and fragmenting liquidity. With UNVAULT, a Cross-Chain Mint is unified.
The minter selects:
- The chain where the NFT will first exist
- The token they wish to use for payment
UNVAULT processes the mint, deploys the appropriate Echo Contract, and delivers the NFT directly to the selected chain while registering it in the canonical UNVAULT registry.
This preserves:
- Single canonical identity
- Royalty enforcement at the contract layer
- Multi-chain mobility without duplicate active instances
Instead of fragmented deployments, projects maintain one cohesive collection architecture across chains.
Built for Real Trading
A complete environment designed around real asset ownership and enforcement.
Vertically Integrated
Not just a listing interface. A complete trading environment with native vault logic integration.
Royalty Enforcement
Structural enforcement of creator royalties that travels with the NFT across all chains — not marketplace preference.
Flexible Custody
Supports both custodial and non-custodial flows based on user preference.
Coming Soon
Proprietary NFT AMM
Automated market making for NFT collections — deploy liquidity pools, earn trading fees, and enable instant buys and sells without waiting for a counterparty.
The UNVAULT Marketplace will feature a proprietary NFT Automated Market Maker (AMM) — a set of on-chain liquidity pools that enable instant, permissionless trading for any collection listed on the platform.
Unlike traditional order-book marketplaces where sellers must wait for a matching buyer, the AMM uses bonding-curve pricing to provide continuous, algorithmic liquidity. This means collections always have a live floor price and every NFT can be bought or sold instantly.
Liquidity providers deposit tokens, NFTs, or both into collection-specific pools (vaults) and earn a share of every trade fee generated by that pool — turning idle holdings into a yield-generating position while simultaneously improving the trading experience for the entire collection.
Dual-Sided Liquidity Pools
Deploy both tokens and NFTs into a pool. The AMM uses a bonding curve to price trades, so liquidity is always available for instant buys and sells.
Earn Trading Fees
Every swap through a pool generates a fee. Liquidity providers earn a proportional share — passive yield on NFT and token holdings.
Collection Vaults
Projects can bootstrap their own AMM vaults to guarantee a price floor and instant liquidity from day one — no reliance on external market makers.
Cross-Chain Compatible
Because the AMM is built on top of the UNVAULT protocol, pools work across chains. An NFT vaulted from Ethereum can be traded on ApeChain via the same pool logic.
