ERC-7683

What Is ERC-7683?

The standard builds upon years of development of Across' solver network, extending it into an open and flexible framework that others can build upon.

Imagine trying to swap tokens from one blockchain to another - traditionally, this would require multiple steps: bridging tokens, waiting for confirmations, and then swapping the tokens. With ERC-7683, users can specify their desired end result (like "swap ETH on Arbitrum for USDC on Optimism"), and the network of relayers competes to execute this request in the most efficient way. 

ERC-7683's intent-based approach enables faster cross-chain interoperability than traditional messaging protocols because relayers assume finality risk. The goal of ERC-7683 is to pave the way for a more unified experience that makes Ethereum feel like one chain again. To this end, the standard is designed to be complementary to existing interop solutions including Superchain, Agglayer, storage proofs, ZK proofs, Hyperlane, Axelar, Wormhole, and more. 

By providing a unified way to handle crosschain interactions, ERC-7683 aims to make the multichain nature of Ethereum invisible to end users.
