Accepts ETH and ERC20 deposits, emitting Enter
and EnterToken
events for the Signet Node
Maintains the list of assets allowed to enter the Rollup.
The Passage
contract facilitates asset transfers between Ethereum and Signet. ETH deposits trigger Enter
events, prompting the Signet Node to mint ETH for the recipient. Similarly, ERC20 deposits trigger EnterToken
events, leading to the minting of corresponding tokens on Signet.
A multisig account, tokenAdmin
, manages the contract's key functions. The administrator maintains an allowlist that prevents most ERC20 tokens on Ethereum from entering Signet.
