Build with Tab
Everything you need to take a stablecoin payment with Tab — the wallet model, the smart contracts, the REST API, and the webhooks you'll point at your backend. If you're picking this up cold, start with the Quick start; if you came for the on-chain side, jump straight to the contracts.
Quick start
From sign-up to your first paid invoice in under five minutes.
Smart contracts
TabRouter, TabBotRouter — addresses, ABIs, and how to call them.
Orders API
Create, list, and listen for the orders your customers pay.
Security model
How keys, signatures, and on-chain checks work together.
