ERC-7683

ERC-7683 is a proposed Ethereum standard, published in 2024 by Uniswap Labs and the cross-chain bridge Across, for expressing cross-chain intents in a common format. An intent is a signed order describing an outcome, for example "swap these tokens on one network and deliver at least this amount on another", rather than the exact steps to get there. Specialized parties called fillers or solvers compete to fulfil the order, typically fronting the funds on the destination chain and being repaid from the user's locked tokens on the origin chain once settlement is confirmed. By standardizing the order structure and the settlement contract interface, ERC-7683 aims to let many applications share one network of fillers instead of each building its own, deepening liquidity and making transfers between layer-2 networks faster. It fits within wider work on cross-chain communication and blockchain interoperability. Also see DEX aggregator.
