Stablecoin payments on Base
Native USDC, two-second settlement, no gas for the buyer.
Base is where most Tab integrations start. The lowest fees we deploy to, the deepest USDC liquidity outside of mainnet, and the simplest path from sign-up to a working checkout.
Why merchants pick Tab on Base
Native USDC
Settle in canonical Circle USDC — no bridged variants, no FX, no surprises on the merchant's bank statement.
Sub-cent gas
Two-second blocks at fractional-cent gas. Sponsored by Tab's relayer so your buyer never sees a gas token.
Permit support
USDC on Base implements EIP-2612, so first-time buyers don't need a separate approve transaction. One signature, settled.
Drop into the Base integration in a day.
Same EIP-712 signature, same router contract, same REST API you already use on every other chain. The only thing that changes is the chain id and the stablecoin address.

Technical notes
Finality
Tab treats payments as settled at the first confirmation. Optimistic finality back to L1 takes a week but isn't needed for in-protocol flows.
Webhook latency
Most order.completed events fire under two seconds after the buyer signs. The indexer reconciles if a block briefly reorgs.
Refunds
Just another payment in the other direction. Tab charges 1% per leg unless you flag the order as a refund via the API.
