Cross-Chain Swap
Odos has partnered with Across Protocol to enable seamless cross-chain, intent-based swaps powered by our proprietary Smart Order Routing algorithm.
Across is the only production-ready cross-chain intents protocol, enabling fast, low-cost, and secure interoperability across chains by separating intent execution from settlement validation. This allows users to swap a token on Chain A to a different token on Chain B in a single flow — no manual bridging or multi-step processes required.
Unique to Odos
Odos is the only protocol that allows users to bridge from multiple tokens on the source chain to a single token on the destination chain — all within a single transaction. This unlocks powerful new use cases like portfolio rebalancing, exit liquidity aggregation, or consolidated transfers across chains, with the best available rates.
