Logic is the world's financial infrastructure, unifying traditional and digital payments into one.
Connected to the rails that move the world
From a customer tap to merchant cash, Logic orchestrates cards, banks, stablecoins, and on-chain transfers with intelligent routing and treasury-backed instant settlement.
Your balance reflects payment intent the moment it is confirmed. Logic treasury pools front the liquidity while underlying rails settle in the background.
Per-transaction routing across rails, cards, bank networks, or any supported blockchain, optimizing for cost, latency, and reliability in real time.
Prefunded liquidity pools per chain and per banking rail. Cross-chain reconciliation, real-time balance management, threshold alerts.
Accept Visa, Mastercard, Amex, ACH, SEPA, and FedNow. PCI handled. Disputes, refunds, and 3DS taken care of.
USDC, USDT, and DAI on Ethereum, Base, Polygon, Arbitrum, and Solana. Real on-chain verification with no custodial middle layer.
Hooks for KYC, KYB, sanctions screening, AML monitoring, transaction risk scoring, and regulatory reporting.
Logic ships the full merchant surface area. Every capability below is live in the product right now.
Merchants need a hosted link to send customers.
Physical invoices need scannable codes.
Customers need to pay with crypto wallets.
Ethereum, Polygon, and Solana out of the box.
Merchants need to see every payment.
Merchants need to issue refunds on the original rail.
The whole journey happens in seconds, with the merchant credited before the network finalizes.
Hosted checkout, embedded widget, or your own UI calls the Logic API.
The router selects the optimal rail in real time and dispatches the authorization.
Treasury liquidity credits your balance immediately, even before the rail finalizes.
Underlying rails complete asynchronously and replenish treasury automatically.
Logic operates a network of treasury accounts across every supported rail and chain, moving value the instant it is needed and rebalancing automatically.
REST endpoints, signed webhooks, idempotency keys, and typed SDKs. Build a checkout, an invoicing flow, or full marketplace payouts without learning five different rail-specific APIs.
