Plasma on Paymos
Supported assets
- USDT Tether USD
Confirmation speed
A payment is confirmed once the network itself declares the block final — no confirmations to count.
Paymos accepts USDT on Plasma. One asset, one gas token, a dedicated address per invoice — and no claim that the transfer is free. The confirmed amount is credited to the merchant's USDT balance without a forced conversion or a markup hidden in a rate.
What Paymos accepts on Plasma
Plasma carries a single payment asset: USDT. USDC, USD1, DAI and XAUT are not in its catalog, so a customer holding USDC needs a different network.
XPL is the network's gas token, not a payment asset. USDT exists on ten other supported chains as well, and only a transfer that crossed Plasma closes a Plasma invoice — the ticker being identical changes nothing.
How a Plasma USDT payment works
- The merchant creates an invoice through checkout, Payment Links, POS, a CMS plugin, Low-Code SDK, or REST API.
- The customer selects USDT on Plasma.
- Paymos assigns a dedicated deterministic address.
- The customer sends the exact displayed amount over Plasma.
- Paymos detects the transaction and waits for Plasma to finalize it.
- Confirmed funds are credited to the merchant's USDT balance.
HMAC-SHA256-signed webhooks report each status change to the merchant application, keeping payment and order together without merchant-operated blockchain monitoring.
Plasma confirms at network finality
No fixed completion time covers every Plasma payment. What Paymos waits for is the chain's own finalized state, one rule for every invoice size, rather than a block count that climbs with the amount.
Use the Paymos invoice status before fulfillment. A wallet broadcast is not a final order signal, and current network conditions can affect the pending period.
XPL gas and Paymos fees
The fee for sending on Plasma is paid by the payer's wallet, in XPL. Network costs move, and this page makes no promise of a sponsored or zero-cost transfer at any point in the flow.
Paymos covers the network cost of accepting and consolidating the payment. Standard pricing is 1.0% per settled invoice; Enterprise is 0.3% on request. There is no setup fee, monthly fee, minimum volume, reserve, rolling reserve, or charge for unpaid, expired or cancelled invoices.
Settlement stays in USDT
USDT received on Plasma is credited as USDT — no automatic exchange into another asset or into fiat, and no processing charge concealed inside a rate.
Balances are held per asset, not per network, so a Plasma receipt lands in the same USDT total as a Tron or a TON one. At withdrawal, the merchant chooses an available payout network and a whitelisted destination.
Paymos adds no processing commission to withdrawals. A network fee can apply on the payout route you pick — nothing of it is a Paymos charge, and you pay less for the transfer than the chain asks for it.
When to enable Plasma
Enable Plasma when customers already hold USDT there and have XPL for the fee. It appears beside the other supported USDT networks inside the same Paymos integration.
Do not route customers by ticker, and do not repeat a zero-fee claim in a checkout. Show the exact network and let the payer use a route where the correct asset and the gas to move it are both present.
Integration and custody controls
Hosted Checkout, Embedded Checkout, Payment Links and Low-Code SDK show the asset, network, amount, address and QR data. H2H REST API, POS and official CMS plugins support other merchant workflows.
Outgoing transactions are signed on isolated infrastructure. Withdrawal whitelisting separately restricts payout destinations.
Frequently asked questions
Which asset can Paymos accept on Plasma?
USDT, and nothing else. USDC, USD1, DAI and XAUT have no Plasma route.
Are Plasma USDT and Tron USDT interchangeable?
No. They are the same ticker on two networks, and each invoice is closed only by the network it names.
Does the payer need XPL?
The sending wallet needs XPL for the network fee. None of it is credited to the USDT invoice.
Are Plasma USDT transfers free?
No zero-fee transfer is promised here. Network costs are variable, and the payer's wallet pays what the chain asks.
Does Paymos convert Plasma USDT?
No. The payment is credited to the merchant's USDT balance.
How do I enable Plasma payments?
Enable USDT on Plasma in your integration. Compare the supported networks or review the USDT payment gateway.
