Signet to Ethereum

Signet Orders enable atomic, instant, cross-chain swaps between Signet and Ethereum. Orders specify assets in, assets out, and on what chain the assets out should be delivered. Orders can be created by smart contract execution via the Orders Contract, or via an off-chain SignedOrder object.

How Orders Work

MEV Searchers (called Fillers) compete to fulfill each Order by providing the output tokens. Your input tokens are locked on Signet until a Filler completes the swap.

Orders are a form of direct interaction with the MEV ecosystem. You can think of them as a way to express your intent to move assets across chains, while allowing the MEV market to find the best execution strategy.

An Order has two main components:

Inputs: What you’re providing on Signet
Outputs: The assets you want to receive, as well as the chain and address to which to deliver them.

Input and Output structs are specified in the IOrders.sol interface.

Implementation Paths

Choose your implementation based on your stack:

On-chain Orders in Solidity

Build smart contracts that create, fill, or interact with Signet Orders on-chain. Perfect for:

Automated MEV capture
Flash loans across chains
Payment gating
Smart contract exits from Signet

Learn how to work with Solidity Orders

Off-chain Orders in Rust

Build applications that create and fill Signet Orders programmatically. Perfect for:

Market making bots
Order monitoring services
Cross-chain arbitrage
Custom filler strategies
