Uniswap Labs and Across Protocol have collaborated to introduce ERC-7683, a proposed standard for cross-chain trade execution.
The initiative, highlighted in a recent X <a href="https://x.com/Uniswap/status/1821881910055825646" target="_blank" rel="noopener nofollow">post</a> by Uniswap Labs, introduces the new standard’s aim to create a unified framework for cross-chain intents and to improve interoperability between decentralized networks.
The proposal has been made publicly available for review on the Ethereum Magicians forum, seeking to create a structure that various decentralized platforms can adopt to improve user experience and trade efficiency.

Ethereum co-founder Vitalik Buterin expressed his support for the new standard, describing ERC-7683 as “an open standard for marking cross-chain orders.”
Buterin elaborated on the functionality, explaining that if a user wants to move coins from one blockchain, like Polygon, to another, such as Base, the process would involve publishing an ERC-7683 transaction.
The transaction sends the coins from Polygon into a secure “lockbox,” which can only be claimed by someone who can prove they sent the coins to the location on the Base side.
Buterin also noted that the standard incorporates advanced mechanisms such as batching and Merkle proving, which improve the efficiency of cross-chain transaction processes.

ERC-7673 introduces the CrossChainOrder struct code to simplify cross-chain order management by defining essential parameters.
As mentioned in the X post, the new standard ensures that cross-chain orders follow the same structure uniformly, creating a smoother multi-blockchain interaction process.
The proposal also includes a standard “ISettlementContract” code smart contract interface to further improve cross-chain efficiency.

On Aug. 9, <a href="https://cointelegraph.com/news/vitalik-buterin-ether-transfer-8-million">Buterin’s wallet address transferred</a> 3,000 Ether (<a href="https://cointelegraph.com/ethereum-price">ETH</a>), worth over $8 million, to a new multisignature wallet.
According to an X post by Lookonchain, the transfer details could suggest that Buterin “possibly” intends to donate the funds.
The funds were sent to the unknown wallet “0xfEB,” potentially belonging to a charitable organization, but this is still unconfirmed.
