Settlement Options

After a payment is confirmed and funds are swept to your merchant wallet, you have the following settlement options:

Keep as Stablecoin

Funds remain as USDC or USDT in your merchant wallet. No conversion fees. Withdraw to any external address at any time.

Convert to Fiat

Request conversion to USD, EUR, or other fiat currencies through Paratro’s off-ramp partners. Conversion fees and processing times apply.

Fiat conversion is available upon request and subject to KYB verification. Contact your account manager or reach out via the Dashboard for details.

Chain Selection

When a customer opens the payment page, they can choose which chain to pay on. Consider these factors when configuring your preferred chains:

Factor	Recommendation
Lowest fees	Base, Polygon, Solana, BSC
Fastest confirmation	Solana (~400ms), Base (~2s)
Largest user base	Ethereum, Tron (especially in Asia)
Maximum compatibility	Enable all supported chains

Each chain has different confirmation requirements. Do not consider a payment final until you receive the payment.settled webhook event.
