The Stablecoin Payment Gateway
Accept USDC and USDT across 5 blockchain networks (4 per token). 1% flat fee. Zero volatility. Instant settlement.
Accepting crypto payments traditionally meant dealing with Bitcoin price volatility, hundreds of tokens, and confused customers sending the wrong coin on the wrong chain. Most "crypto payment processors" add complexity instead of removing it.
PYMSTR is stablecoin-first. We support USDC and USDT, the two largest stablecoins pegged 1:1 to the US dollar. No volatility, no token confusion, no hundreds of options. Simple, stable, predictable.
Three steps, on-chain.
Customer selects stablecoin
Choose USDC or USDT. Enforced payments mean they can only use options you've approved.
Selects chain
Ethereum, Base, Polygon, Arbitrum, or BNB. Your merchant settings control which are available.
Pays exact amount
The exact amount transfers on-chain. No volatility between payment and settlement.
What you get.
Zero Volatility
USDC and USDT are pegged 1:1 to USD. The amount paid is the amount received. Always.
Two Coins, Not 300+
Unlike NOWPayments with 300+ tokens, PYMSTR focuses on the two stablecoins that matter. Less confusion, fewer errors.
Enforced Payments
Customers can only pay with options you've approved. No wrong-chain, wrong-token, or wrong-amount errors.
Multi-Chain Efficiency
5 chains from $0.01 gas (Polygon) to $10 (Ethereum). Match the chain to the transaction size.
