Cross-Chain
Experimental release — not for production use
This SDK is an early, preview release and has not been audited. It handles transaction and signature data for cross-chain value transfers, so a defect in the SDK could result in permanent, irrecoverable loss of user funds.
Do not use this SDK in production or with real user value.
The cross-chain package provides a standardized interface for cross-chain token transfers. It lets you fetch quotes from multiple bridge providers, execute transfers, and track orders through a unified API.
It follows EIP-7683 for cross-chain intent structures.
What it does
- Fetch and compare quotes from multiple providers (Across, Relay, OIF, LiFi)
- Execute cross-chain transfers via signature (gasless) or transaction
- Track orders from initiation to completion
- Aggregate quotes with configurable sorting strategies
