One balance. No gas token.
Every fee — send, swap, mint — is denominated in USDC. You never hold SOL just to move, you never watch a gas tank drain to zero at the worst moment.
HOW IT WORKS
One balance in, one currency out. No gas token to hold, no top-ups to remember, no second asset to juggle. USDC is the whole story.
Fund one USDC balance — the only asset you ever keep. No SOL on the side, no gas tank to watch, no bridging.
Send, swap, or mint. Every fee is quoted and charged in USDC up front. One balance, one currency, one number you actually understand.
SOL liquidity providers front the lamports for your transaction and earn the fee spread. The gas market is permissionless — anyone can stake.
Your transaction lands atomically on Solana mainnet with sub-second finality. The USDC fee settles in the very same instruction.
WHY PAYR
Four properties built into how the network settles. Not promises, not roadmap items — the mechanics of paying gas in USDC, working today.
Every fee — send, swap, mint — is denominated in USDC. You never hold SOL just to move, you never watch a gas tank drain to zero at the worst moment.
Liquidity providers stake SOL to fund network gas and earn the fee spread. The gas market is open and permissionless — no allowlist, no privileged relayer.
Full Solana execution — 65,000 TPS, sub-second finality, the entire SPL ecosystem. No bridge, no wrapped assets, no second chain you have to trust.
The Payr wallet is non-custodial. Keys never leave your device, there is no admin withdrawal function, and the network can never touch your funds.
None of this asks you to trust a team — only to hold one balance and read the on-chain accounts yourself. Program on Solscan ↗
PROOF
This is the actual output of Payr's relayer acid test — a wallet holding zero SOL moves USDC and pays the fee in USDC. The relayer fronts the gas and gets paid back in stablecoin.
── PAYR GASLESS PROOF ─────────────────────────────
user SOL before: 0 (a true zero-SOL wallet)
user USDC: 5.00 → 3.49 (sent 1.50 + 0.01 fee)
recipient USDC: 0.00 → 1.50
treasury USDC: +0.01 (fees accumulate in USDC)
user SOL after: 0 ← never paid any SOL
relayer SOL: 1.994435 → 1.992386 (paid the gas)
✅ PASS — zero-SOL user moved USDC; relayer paid gas;
fee collected in USDC.

Common stuff first. If something below doesn't cover what you're hitting, reach us directly — we read every message.
For gasless USDC transfers — no. A relayer fronts the SOL gas and collects a flat 0.25 USDC fee instead; it is live on Solana mainnet in the app. Regular swaps and sends still settle their network fee in SOL as usual.
Yes — it runs on mainnet today. Open the app's Gasless tab: a wallet holding only USDC (zero SOL) signs one transaction, and the relayer co-signs, pays the gas, and collects a 0.25 USDC fee. The relayer validates every transaction against a strict allow-list (only TransferChecked on the USDC mint, fee to the treasury enforced) so it can never be drained.
SOL liquidity providers. They stake SOL into the gas market, front the lamports that Solana requires for each transaction, and earn the fee spread between the USDC you pay and the raw gas cost. It's an open, permissionless market — anyone can stake and earn.
No. The Payr wallet is fully self-custody — your keys never leave your device. There is no admin key, no multisig override, and no withdrawal function the team controls. You hold your balance; the network only routes execution.
Neither. Payr is native Solana execution on mainnet-beta — 65,000 TPS and sub-second finality, using the real SPL ecosystem. There is no bridge, no wrapped assets, and no second chain to trust. The USDC-fee layer sits on top of ordinary Solana transactions.
Every fee is denominated in USDC and quoted up front before you sign. The amount covers the underlying SOL gas plus a small spread that goes to the stakers who front it. No hidden gas tank, no surprise top-up, no separate SOL cost.
Stake SOL into the gas market and it funds the lamports for network transactions. In return you earn the spread on every fee those transactions pay in USDC. The more the network is used, the more the staking pool earns — and staking is permissionless, so there's no gatekeeper.
