In 2025, the Ethereum (ETH) L2s ecosystem could finally solve all the problems of cross-network interoperability and silo liquidity. As explained by Ethereum (ETH) enthusiast going by the name @FigoETH, ERC-7683 “Cross Chain Intents” will be a game-changer.
ERC-7683 makes Ethereum borderless, introduces Intents and Fillers
The introduction of ERC-7683, the latest cross-chain standard for the Ethereum (ETH) ecosystem, will make the L2 user experience 10x better. This will in turn make Ethereum’s L2s more attractive to new generations of developers, says @FigoETH on X.
2025 will be the year that Ethereum’s L2s will become unified and interoperable beyond Superchain and other solutions.
How? ERC 7683 will make the magic happen. No hard fork required.
Critical ecosystem players such as Optimism, Arbitrum, Unichain, Polygon, Taiko and many more…

ERC-7683 will finally make Ethereum’s L2s interoperable, including existing Polygon, Optimism, Arbitrum and all future ones. Blockchain users can move the NFTs from Arbitrum to Optimism and exchange tokens from Polygon to Base.
Once implemented, ERC-7683 will allow users to create “filler networks,” interoperability spaces designed to standardize the expression of intents – such as token swaps, NFT transfers, and governance votes – across EVM chains.
Filling network organizers will compete to fulfill cross-chain intentions with optimized efficiency and minimized costs. These unified filling networks will facilitate interoperability, remove the burden on developers, and remove the complexity of cross-chain transactions from user experiences.
ERC-7683 will therefore create a unified framework for cross-blockchain interactions on EVM as all operations will be routine.
Towards cross-chain apps and uniform governance
As described in a detailed explainer post, ERC-7683 will enable decentralized applications to streamline governance across multiple chains.
For example, a DAO could easily manage governance proposals across various Layer Two networks and sidechains, giving their community broader access to voting processes in a resource-optimized manner.
ERC-7683 allows dApps to use different chains for specialized functions. This paves the way for DeFi apps that manage transactions on Optimism (OP) for speed, while securing assets on Ethereum (ETH) for maximum security, seamlessly bridging both networks without any additional steps.
The concept was introduced in November 2024 by Mark Toda, Matt Rice and Nick Pai, according to Ethereum’s official EIP portal.
