Swapping USDB — FAQ
How do I swap USDB on Blast?
Connect a wallet, keep USDB as the token you want, enter an amount, and review the best route. SwapRoute compares live quotes from numerous aggregators and shows route details and the minimum received before you sign — no account needed.
What's the best rate to swap USDB?
SwapRoute doesn't rely on a single venue. It queries every capable provider at once and ranks routes by the net amount you'd actually receive, so the best available USDB rate is shown first. Rates move with the market, so the quote refreshes as you type.
Can I buy USDB with ETH or a stablecoin?
Yes. Pay with ETH, USDC, USDT or another token you already hold and route to USDB. If your input is on a different chain, SwapRoute finds a cross-chain route automatically.
Is USDB available on other chains?
This page covers USDB on Blast. SwapRoute also supports routing across 11 EVM networks, so you can bridge into USDB from another chain in a single flow.
Does SwapRoute hold my USDB?
No. SwapRoute is a non-custodial routing interface. You connect your own wallet, review the transaction, and sign directly — your USDB never touches our servers and we never hold your keys.
