What does PYMSTR® SDK do?
PYMSTR adds a stablecoin payout rail to your store or marketplace via a hosted checkout. We handle wallets, orchestration & settlement, automated fee-splits, and paymaster-sponsored gas so customers and sellers never see network fees.
Who is PYMSTR® for?
Online merchants and marketplaces, plus commerce/PSP platforms that want fast, global payouts without rebuilding their stack.
Do we need a contract to start?
No. Self-serve signup: create an account, get sandbox keys, set redirect URLs and a webhook secret, and start testing. Upgrade to production from the dashboard.
Which chains are supported?
USDC on leading EVM L2s, Base by default, with additional chains available as needed.
What about fees and chargebacks?
Pymstr takes a fixed percentage fee; network fees are hidden from the user (sponsored). On-chain finality means no chargebacks; refunds are handled as reversals under your policy.
