Solana · USDC

Stablecoin payments on Solana

Highest stablecoin throughput outside EVM, same Tab UX.

Same Tab UX as EVM: one signature unlocks gasless payments, tips, subscriptions, and Smart Pay across chains. Settled in 400ms at fractional-cent gas, with full parity for USDC and native SOL.

Why merchants pick Tab on Solana

Native SPL USDC + native SOL

Tab supports both. USDC is canonical Circle. Native SOL is held as wSOL inside the user's wallet so the audited Subscriptions Delegation Program can spend it gaslessly. Phantom/Backpack/Solflare auto-sum wSOL with native SOL, so it shows up as a single SOL balance.

One-signature Smart Pay

One delegation tx (signed once during onboarding) lets Tab spend USDC and SOL on the user's behalf up to per-day caps. Every payment after that is fully gasless. Caps are user-set and revocable anytime.

Cross-chain in/out

Smart Pay routes Solana ↔ EVM in one click via relay.link. Tip SOL even when you have no SOL — Tab pulls USDC from your EVM 7702 delegation, bridges, and lands SOL on Solana.

FOR DEVELOPERS

Drop into the Solana integration in a day.

Same REST API you already use on every other chain. On Solana the wire format is an Ed25519-signed Anchor instruction (not EIP-712), routed through the tab-router program; the request/response shape on Tab's side is identical.

Technical notes

Subscriptions Delegation Program

Smart Pay on Solana uses the Solana Foundation's Cantina-audited Subscriptions Delegation Program (De1egAFMkMWZSN5rYXRj9CAdheBamobVNubTsi9avR44). Standard SPL Token approve + transferRecurring; no Tab-custom on-chain program.

Tab Subscriptions Program

Recurring stablecoin payments use a dedicated Tab Anchor program with a 0% Personal tier and a 1% Business tier. Same publish-once + auto-renew UX as the EVM TabSubscriptionRouter. Tab covers SOL gas on every charge.

EVM ↔ Solana auto top-up

POST /api/solana/top-up bridges native SOL from your EVM USDC balance via relay.link, so a user who lands on Tab with only EVM USDC can still onboard to Solana in one click. No buy-SOL-on-Coinbase-first step.
