Question 1

Does o1.exchange Swap support swaps on Base?

Yes. Base is a first-class chain on o1.exchange Swap, alongside Bitcoin, Solana, and other major EVM chains. The o1 router is included as a same-chain option on Base, in addition to the standard set of aggregators.

Question 2

What chains does o1.exchange Swap support?

Accepted Answer

o1.exchange Swap currently supports swaps across Base, Bitcoin, Solana, Ethereum, Arbitrum, Optimism, Polygon, BNB Smart Chain, Avalanche, Linea, Scroll, Blast, and Ink. Cross-chain swaps work between any two supported chains; additional networks may be enabled over time.

Question 3

Which routers does o1.exchange Swap aggregate?

Accepted Answer

Every quote is fanned out across o1's own router, 1inch, Jupiter, 0x, Relay, LI.FI, deBridge, KyberSwap, Odos, OKX, ParaSwap (Velora), Enso, and DFlow. The best route wins automatically, and o1's router is a first-class option on Base.

Question 4

Is o1.exchange Swap self-custodial?

Accepted Answer

Yes. Every signature stays in the user wallet. o1.exchange Swap builds the transaction; the wallet signs and submits it. Private keys never touch the backend.

Question 5

How does cross-chain swapping work on o1.exchange Swap?

Cross-chain swaps route through Relay, LI.FI, or deBridge depending on which gives the best quote. Source-chain settlement and destination-chain delivery are tracked in the same panel until both confirm.

Question 6

Does o1.exchange Swap support Bitcoin?

Accepted Answer

Yes. Bitcoin can be used as a source chain via Relay, with destinations across Base, Solana, and major EVM chains. Bitcoin signing uses Dynamic's native sendBitcoin flow inside the user wallet.
