Transfers on Signet

Enter Signet

Passage is the bridge contract on Ethereum that moves assets into Signet. Deposits arrive on the rollup in the same block they’re submitted.

Passage has two entry points: one for ETH (sent as msg.value) and one for ERC-20 tokens (requires a prior token approval). Both take a rollupRecipient address that receives the tokens on Signet.

The Signet node watches for Enter and EnterToken events on the Passage contract. If the event fired, the deposit was processed – no additional confirmation is needed on the rollup side.

Create and submit orders to move assets from Signet to Ethereum. For background on the order lifecycle and atomic settlement, see How orders work.

Order data model

Every order has inputs (what the user gives up on Signet) and outputs (what they receive on the destination chain).

Input:

Field	Description
`token`	ERC-20 address on Signet. Zero address for native USD.
`amount`	Amount in the token’s smallest unit (e.g., wei).

Output:

Swap within Signet

When you want a different token on Signet without crossing to Ethereum, create an order where both input and output are on the rollup chain. The order stays entirely within Signet and settles without touching Ethereum at all.

For order structure, pricing, and filler economics, see the Exit Signet shared intro. The order model is identical – only the output chainId differs.
