ERC-7683
An Ethereum standard for cross-chain intents — defines a uniform interface for users to express "I want X on chain B by paying Y on chain A" across many resolvers.
ERC-7683, finalized in 2024, standardizes how cross-chain intents are expressed. A user signs an intent specifying source/destination chains, input amount, output amount, deadlines, and resolvers; any resolver that meets the constraints can fill the intent and collect the spread as their fee.
The standard is built around two interfaces: IOriginSettler
(on the source chain) and IDestinationSettler (on the
destination). Across, UniswapX, and several other intent
protocols implement it, making cross-chain UX increasingly
interoperable across providers.
