Anywhere stablecoins go, Tab is the checkout.
Four shapes of payment that Tab is built to handle out of the box. The contracts are general enough to support more — these are just the ones we've already shipped tooling for.
A point-of-sale that doesn't take a cut of your float
Generate a QR at the till, customer scans, pays in stablecoin, you have settled funds in your wallet before the receipt prints. No card processor sitting on three days of your float, no chargeback risk.
- →Web POS that runs in any browser
- →Printable QR for cash registers
- →Webhooks into Square, Shopify, custom backends
A tip jar that resolves to your handle, not a wallet address
Pin @yourname on your profile and accept tips, paid subscriptions, or one-off commissions. Your audience never sees a hex string, never opens a wallet popup, never pays gas.
- →Hosted checkout pages per product
- →One link covers all six chains — Base, BSC, Solana, Ink, Celo, Tempo
- →Optional invoicing with email receipts
Treasury payouts without a multisig ceremony
Run grant programs, contributor stipends, or quadratic funding rounds in one go. The sponsor approves a total budget once, then Tab pushes each payout. Duplicate payouts are blocked automatically on-chain.
- →One payout per recipient, enforced on-chain
- →Sponsor wallet stays in custody — Tab just moves what was approved
- →Full payout history available via webhooks and exports
An API an autonomous spender can use without supervision
Tab handles resolve to wallet addresses, so an LLM agent can pay '@coffee-shop' the same way a human can — no addresses, no gas tokens, no chain-switching to teach it.
- →Per-agent spend limits and rate limits
- →Deterministic JSON responses for tool-calling models
- →Hard cap on losses if the agent misbehaves
Have a use case we haven't built for?
The contracts are open and the API is fully documented. If you can describe the flow, Tab can almost certainly settle it.
