Frequently asked questions

What is cbBTC and how is it different from WBTC?
cbBTC is Coinbase's wrapped Bitcoin, minted by Coinbase and deployed natively on Base. Unlike WBTC's BitGo custody, cbBTC keeps custody with Coinbase's regulated infrastructure. Both track Bitcoin 1:1, so the choice mostly comes down to which wrapper your chosen ecosystem and pools support.
Why swap ETH to cbBTC on Base instead of Ethereum?
On Base, cbBTC is deeply integrated and gas is a fraction of a cent. You get Bitcoin exposure without paying mainnet-level fees to make the trade. AEXI routes through the tightest cbBTC pools on Base so the wrapper is bought at the best available price.
