Untitled Bank Review 2026: Permissionless Lending on Soneium

Untitled Bank is a permissionless and modular lending platform on Soneium. Its tagline is "Where anyone becomes a bank," and the core idea is that any user can create a Bank, an independent lending vault in the ERC-4626 format.

The platform aims to combine modular lending, where markets are separate, with the ease of a single pool through an aggregation layer that unifies liquidity. Users can earn by depositing, borrow against collateral, and use leverage or repay-with-collateral features, according to the project's docs.

It is small. The protocol was listed in January 2025, holds roughly $107,000 in TVL and has no token of its own. Two audits are listed.

Untitled Bank splits lending into Banks. Each Bank is an independent lending vault in the ERC-4626 format, which is a standard interface for tokenised vaults. Anyone can create one by calling the createMarket function in the Bank contract and supplying the required parameters.

Depositors supply an asset and earn interest paid by borrowers. Borrowers post collateral, and the Bank contract values that collateral using a price provider, also called an oracle. Custom price providers are allowed, so each market can choose its own source.

A layered system sits on top and aggregates liquidity across modular Banks. The aim is to give users the simplicity of one large pool while keeping the isolation of separate markets.

Its homepage does not publish a fee schedule. Interest rates in lending markets are set by the market's own parameters and borrower demand, and users also pay Soneium network gas for transactions.

Any protocol fee or market-creator fee should be visible in the docs and in the app before you confirm a deposit or loan.

Two audits are listed for the protocol, but its homepage does not name the auditors or publish the reports. Users should read audit scope and findings in the docs before depositing.

Lending carries smart-contract risk, oracle risk and liquidation risk. Because markets are permissionless and can use custom price providers, the quality of each market's collateral and oracle varies. The protocol is young and holds little TVL, so it has had little time to prove itself under stress. Licensing and regulatory status are not published. Never deposit more than you can afford to lose.

Untitled Bank fits experienced DeFi users on Soneium who are comfortable judging collateral and oracle risk, and builders who want to launch a custom lending market. It is less suited to beginners or anyone who needs deep liquidity and a long track record.
