A smart contract implementation of ERC-7683: Cross Chain Intents Standard, enabling secure cross-chain transactions. This implementation is inspired by and adapted from Candide Labs' CandideWallet contract.
ERC-7683 is a proposed standard for cross-chain intents that aims to unify how different protocols handle cross-chain transactions. Developed collaboratively by Across and Uniswap Labs, the standard:
- Enables sharing of infrastructure, filler networks, and orders across cross-chain bridging and trading systems
- Provides a unified framework for intent-based systems to specify cross-chain actions
- Allows users to express desired outcomes without worrying about the underlying mechanics
- Supports both gasless and onchain cross-chain orders
- Creates a more efficient and competitive market for cross-chain transactions
This implementation builds upon the work of Candide Labs, specifically their CandideWallet smart contract implementation. The base wallet functionality has been extended to support ERC-7683's cross-chain intent standard while maintaining the security features of the original contract.
The project combines:
- Account abstraction capabilities from Candide's wallet implementation
- ERC-7683's cross-chain intent standard
- Custom settlement logic for cross-chain transactions
