Otto operates across a growing set of EVM chains plus Solana and X Layer. Cross-chain bridges and DEX aggregation are routed through Li.Fi; the authoritative live list of supported bridges and aggregators is Li.Fi’s own, so refer to the Li.Fi Tools API for current per-chain coverage — integrations evolve.

​
Chains by surface

Different Otto surfaces reach different chains. Check the surface you’re using:
The Trade Execution agent’s 6-EVM-plus-Solana scope is its execution/portfolio reach and is intentionally smaller than the swap widget’s coverage. If a chain isn’t listed for the surface you’re using, it isn’t reachable there.

​
Supported chains (Li.Fi integration coverage)

Otto uses Li.Fi to aggregate bridges and DEXs across these networks:
  • Arbitrum (ARB)
  • Optimism (OP)
  • Base (BASE)
  • Ethereum (ETH)
  • Unichain (UNI)
  • Polygon (POL)
  • Sonic (S)
  • Binance Smart Chain (BSC)
  • Avalanche (AVAX)
  • Berachain (BERA)
  • ApeChain (APE)
  • Solana (SOL) — cross-chain bridges from EVM, with gas fronting via LI.Fuel
  • X Layer (XL) — via Otto X
For the full, current list of bridges (Stargate, Across, Squid, Relay, and more) and DEX aggregators (0x, 1inch, LI.FI, OKX, and more) available on each chain, query the Li.Fi Tools API — Otto routes through whichever Li.Fi supports for your pair.
