Anvil wallet

What is Anvil (ANVL)?

Anvil is a set of smart contracts on Ethereum that lock up collateral and issue a letter of credit (LOC) against it. The idea is borrowed from banking: an LOC is a promise of payment that is only as good as the funds behind it, and Anvil makes those funds verifiable on-chain. A user deposits collateral into the protocol, an LOC is issued that references it, and any platform that accepts Anvil LOCs can treat that promise as backed, because the collateral cannot be quietly withdrawn while the LOC is outstanding. The intended uses are payments, instant credit on trading platforms, and moving value between platforms or layer 2 networks without waiting for a full settlement first.

ANVL is the protocol's own token. It is a standard ERC-20 that lives on Ethereum, so holding it means holding an ordinary token balance at an Ethereum address, and every transfer is paid in ETH, not in ANVL. The balance does not rebase or accrue on its own; it changes only when you send or receive. There is no separate token account to open and no wrapped version to keep track of, but a small amount of ETH is needed in the same wallet before any ANVL can be moved.

Most ANVL holders touch the token rarely: it sits in a wallet while the protocol's collateral logic does its work elsewhere, and is used when governance or protocol participation calls for it. That pattern favors a key that was never typed into anything. In Tangem the private key is created inside the card and never leaves it, a second card with the same key serves as the backup, and writing down a seed phrase is a choice rather than a requirement. For a token you mostly hold rather than move, a key that has never existed outside the chip is the point.
