Accept USDT Payments.

PYMSTR supports USDT on Ethereum, Polygon, Arbitrum, and BNB Chain. You control which chains to accept.

USDT has maintained its $1 peg since 2014 and processes billions in daily volume. It's the most liquid stablecoin in the market. PYMSTR settles USDT directly to your wallet. Non-custodial, so you hold the funds.

Both, ideally. USDT has higher liquidity and dominates Asia-Pacific. USDC has stronger regulatory backing and institutional trust. PYMSTR lets you accept both with the same 0.5% fee.

Instant crypto settlements. USDT arrives in your wallet the moment the transaction confirms on-chain, typically 2-15 seconds depending on the chain (Polygon/Arbitrum: ~2 sec; BNB Chain: ~3 sec; Ethereum: ~15 sec). No batching, no holdback, no T+3 wait. See /features/instant-settlement for the full breakdown.

It depends on your customers. Polygon and BNB Chain are cheapest (gas around $0.01-$0.10, 2-3 second settlement) and BNB is especially common in Asia-Pacific where USDT dominates. Arbitrum offers low fees with Ethereum-grade security. Ethereum costs more in gas (~$2-10) but is the most universally supported. You can accept several at once; enforced payments let customers pay only on the chains you choose.

PYMSTR is 0.5% flat with no spreads, no monthly fees, and no setup. Custodial crypto processors typically run 2-3.5% all-in after conversion spreads and withdrawal fees, and card rails charge high-risk merchants 5-10%+ before chargebacks. The 0.5% is the full cost because PYMSTR never converts or holds the funds.
