Marketplace

Collect from buyers. Pay your sellers. One gateway.

A marketplace has two payment jobs, not one. Money comes in from buyers worldwide — in USDT, USDC, ETH, BNB, and the native coin of every network — and it must go back out to dozens or hundreds of sellers. Running one wallet for everyone means mixed funds, tangled keys, and a reconciliation spreadsheet nobody trusts. Suward runs both sides on one gateway across 7 networks: unique address per order, per-vendor balance, on-chain payouts. 0.4% per payment, minimum $1.

The problem

Why marketplaces need per-vendor payments.

A single-merchant checkout collects money and stops. Your platform can't stop there. Each order belongs to a different seller, and at the end of the cycle you owe each of them their share minus your commission. Do that across hundreds of vendors with bank rails and you inherit slow cross-border transfers, FX spreads, and a reconciliation spreadsheet nobody trusts. Which deposit belongs to which order? Which order belongs to which seller? Crypto fixes the rails. It does not, by itself, fix the bookkeeping. That's the part Suward is built around.

Architecture

Give every vendor its own project, its own balance.

Give each seller its own project under your organization, with its own API key, its own webhook URL, and its own balance. Every payment lands attributed to one vendor, so you always know exactly what each seller is owed. Your commission is simply the part you keep. Organizations, projects and roles are live, so a finance teammate can read balances without holding the keys to move money.

Each vendor collects into its own project. You reconcile per vendor, then pay the seller out from that balance and keep the difference — two clean steps, both yours to control.

Payouts

Payouts that don't wait for a bank.

When a payment reaches Success, it's final and ready to withdraw. Trigger a payout from the dashboard and a worker broadcasts it on-chain and confirms it, with a manual operator fallback if a broadcast fails. No 2-to-5-day wire, no intermediary bank, no FX desk between you and a seller in another country. Pay in the same asset you collected, and the amount that left is the amount that arrives.

Payouts are initiated by an org owner from the dashboard, with full control over timing and amount.

Float

Accept any asset — stablecoins steady the float, native coins arrive as-is.

Suward accepts USDT, USDC, and the native coin of each network (ETH, BNB, MATIC, and others). Money sits on your platform between the moment a buyer pays and the moment a seller is paid. If that float is in a volatile native coin, a price swing can quietly turn a profitable order into a loss before payout. Settle in USDT or USDC and the number holds. Suward keeps a payment in the asset it arrived in — what a buyer sends is exactly what lands in your balance — so a USDC balance stays USDC from collect to payout. You hold exactly the asset collected until you pay it out.

Finality

Once it's Success, no chargeback walks it back.

Card marketplaces carry chargeback risk on both sides: a buyer disputes, and you've often already paid the seller. A crypto payment that reaches full on-chain confirmation and Success is irreversible. There is no bank to claw it back. That changes your payout policy for the better: release a seller's funds only after Success, and you never pay out on a payment that later reverses. Refund and dispute policy stays yours to write, since irreversibility removes the bank's recourse for the buyer too.

Reconciliation

Every order gets its own address. Reconciliation stops being a guess.

Reuse one wallet across a marketplace and you spend the month untangling which deposit belongs to which order and which seller. Suward creates a fresh HD deposit address for every payment, so a transaction maps to exactly one order and one vendor with no ambiguity — and signed per-project webhooks fire your settlement logic the moment a vendor's order is paid.

Infrastructure

7 networks, 21 assets, one simple rate.

Collect and pay on Ethereum, BSC, Arbitrum, Optimism, Base, Plasma, Polygon. The 21 assets are stablecoins (USDT, USDC, plus USDC.e on Arbitrum) and the native coin of each network, with the list set by config and growing. The price is 0.4% per payment, minimum $1 — a floor, not a surcharge, and the calculator shows the exact number. A small fixed per-network fee covers the on-chain cost separately: Ethereum $0.20, BSC $0.01, Arbitrum $0.01, Optimism $0.01, Base $0.01, Plasma $0.01, Polygon $0.01.

FAQ

Marketplace questions, answered straight.

You collect into the vendor's project, then pay the seller out and keep the difference. Per-project balances make the math obvious, so your commission is simply the part you keep.

Give each seller its own project under your organization. Every payment is attributed to one project, so each vendor has its own balance, webhook URL and API key. Roles let your team read those balances without the right to move funds.

As fast as the network confirms the payout. A payment is final at Success, you trigger the withdrawal from the dashboard, and a worker broadcasts and confirms it on-chain. No 2-to-5-day wire and no intermediary bank sit in the way.

Crypto has no card chargeback. A payment that reaches Success is irreversible. Release seller funds only after Success and you never pay out on a payment that later reverses.

Suward provides the gateway, address generation, monitoring, balances and payouts, with AML screening on every transaction so you keep a clean audit trail. You verify your vendors as the platform operator — see our AML and Risk pages and take your own legal advice.
