Stablecoin Payments for High-Volume Marketplaces

Split payouts, escrow flows, vendor settlements. One API for every leg of the transaction.

//Operator pain4 surfaces

The friction high-volume marketplaces operators live with.

01 · pain

Multi-recipient settlement is brittle

Marketplaces collect from buyers, then split between vendor, platform, referral, and payment partner. Each split is a separate operation, each with its own failure mode.

02 · pain

Escrow flows need real-time finality

Hold in escrow, release on confirmation, refund on dispute, all in seconds. Card rails can't hit those latencies.

03 · pain

Vendor payout fees compound

Each payout to a vendor costs $1-5 in wire fees plus 1-3% in card-acquirer markup. On 1,000 monthly payouts, that's thousands lost.

04 · pain

Cross-border vendor settlement is messy

Vendors in different countries need different payment rails. Wires, ACH, e-money. Each with delays and reconciliation overhead.

Batch vendor payouts and affiliate commissions in one on-chain transaction

Marketplaces settle to many vendors. Scheduled vendor payouts, affiliate commissions, seller withdrawals: PYMSTR Payouts sends up to 100 of them in one on-chain batch, from your own wallet, at 1% flat.

Create the batch

One API call queues up to 100 recipients, each with their address, amount, and USDC or USDT choice.

Sign once

Any authorized signer approves the whole batch from your wallet. The API creates payouts but can never move funds.

Atomic settlement

The whole batch settles or the whole batch reverts. You never end up with half a payroll run sent.

No jargon.

When you create a payment link or checkout session, you specify split ratios. E.g. 80% vendor, 15% platform, 5% referral. The single customer payment is automatically distributed on-chain to each recipient in one transaction.

Yes, with PYMSTR Payouts. Payment splitting divides a single incoming payment; when you are instead sending money out to many recipients (scheduled vendor settlements, affiliate commissions, marketplace payouts), Payouts batches up to 100 of them into one on-chain transaction. Whoever opens the payout link signs and pays, usually from your own wallet. 1% flat, on top.

Yes. Hold funds in your platform wallet on confirmation, release to the vendor on order completion (manual or webhook-triggered), refund to buyer on dispute. Talk to us if you need on-chain escrow primitives.

Vendors need a wallet address to receive stablecoins. They can use any wallet (Safe, MetaMask, exchange-issued). No platform sign-up flow, just provide an address.

PYMSTR webhooks fire on every settled transaction and split. Your billing system gets a structured event per leg. Buyer charge, vendor split, platform split. For clean reconciliation.
