Anvil (ANVL): Posting Collateral to Issue Payment Guarantees

A guarantee, not a loan, built on Ethereum collateral

Anvil is a decentralized finance protocol on Ethereum that lets users post collateral and issue ‘programmable letters of credit’, which are payment guarantees. ANVL is the governance token that steers the protocol.

1. What it is and who builds it

Anvil describes itself as a shared collateral layer for businesses. DeFi usually centers on borrowing against collateral, but Anvil focuses on backing a promise to pay rather than lending money. According to the project’s announcements, The Acronym Foundation started development, and Anvil Research Labs now leads growth and the building of tools for companies.

ANVL has a total supply of 100 billion and is used to vote in Anvil’s governance. On the Crypto Nation map, ANVL stands in Ethereum City (the capital), because it is a token issued on Ethereum. The protocol is described as charging no fees for now, and any future fee would need a vote of ANVL holders.

2. A vault and a letter of credit

Users deposit assets such as the stablecoin USDC or WETH (ether wrapped in a token format) into Anvil’s vault contract. The vault splits balances into available and reserved portions, and issuing a letter of credit locks the matching amount. The named beneficiary can then claim the guarantee on demand.

A guarantee can be backed by the same asset (USDC for USDC) or a different one (WETH for a USDC guarantee). In the second case the contract watches the collateral ratio and lets anyone trigger a conversion of collateral as it nears a threshold. Shared pools need advance notice to withdraw, and the creator is said to keep custody of the collateral, and any yield, until a guarantee is called.

3. Uses and milestones

Anvil’s examples include event sponsorship guarantees, deposits, buy-now-pay-later, exchange credit, trade finance and auctions. In many of these the counterparty only needs proof that the money exists, not the money itself. That is why the project says a structure that locks collateral without interest or debt fits.

The project says it launched an institutional product at Consensus 2026 in May 2026 and was accepted into the Ethereum Security Subsidy Program in June. On 7 October 2026 it announced an enterprise SDK (a developer toolkit) and a roughly 5 million dollar purchase of ANVL led by Founders Fund, with participants including Pantera Capital and Bullish.

4. Things to know

Anvil is an early-stage protocol. Its contracts were audited by OpenZeppelin and Trail of Bits and run bug bounties (rewards for reporting flaws), but an audit does not prove the absence of errors. Cross-asset guarantees depend on collateral monitoring and conversion working on time, and how that behaves in sharp market moves needs more testing.

The model also relies on eligible collateral that already lives on-chain, which limits its reach, and rules on on-chain guarantees are still unclear. Much of the description above comes from the project’s own announcements and a research piece it commissioned, so it is worth reading alongside independent assessments. For now the only token use described is governance voting.
