Unlink

Unlink is a privacy account layer deployed as a smart contract on existing EVM chains; it is not a separate chain and involves no bridge. Users deposit ERC-20 tokens into the contract, where balances are held as encrypted UTXO notes. Each private operation is proven with a Groth16 zero-knowledge proof generated by the SDK, and the contract verifies that the state transition is valid without learning the sender, recipient or amount. The interface exposes four operations: deposit, transfer, withdraw and execute, where execute spends a private balance in an external contract call, such as supplying to a lending market, and returns the result to a private balance. Transfers and withdrawals are relayed and execute runs as a sponsored ERC-4337 UserOperation, so users need no native gas token. Target users are stablecoin issuers, payment processors and market makers; the problem is that public ledgers broadcast counterparties, balances and payment flows by default. Scoped disclosure views let compliance teams review records without the full account graph.

In June 2026 Unlink went live on Monad, reusing the chain's Aave, Morpho, Uniswap and Curve markets, which hold roughly USD 350 million in TVL, so private balances can be routed into them through execute. An integration with Euler applies the same model to institutional lending vaults: collateral parameters, interest rates and liquidation logic stay unchanged, and only the visibility of the interaction is altered. Deposits and withdrawals still reveal amounts and addresses, so linkability is reduced by splitting amounts and timing rather than removed.
