Let customers pay USDC without preparing a native gas token
For supported payment flows, SoloPay sponsors the network fee so customers can complete a USDC checkout without first acquiring ETH or another native token.
Why SoloPay
A simpler crypto payment gateway
gasless USDC payment
Remove one of the most confusing steps in wallet checkout and reduce abandonment caused by missing native tokens.
Actual product flow
SoloPay uses EIP-712 signatures and an ERC-2771 relayer. The relayer verifies the signed request, pays network gas, submits the transaction, and tracks relay status.

Sign permit/forward request

SoloPay does not add a separate identity review or payout-approval step for supported payment gateway flows. Verification required by a wallet, exchange, merchant policy, industry, or applicable law may still apply.
No. Wallet addresses and transactions remain visible on public blockchains. A No-KYC payment gateway does not mean anonymous, untraceable, or exempt from applicable obligations.
No. SoloPay payment gateway scope is separate from any customer-verification, contractual, tax, delivery, medical, AML, or other legal duties that may apply to the merchant.
For supported gasless payment flows, SoloPay sponsors the gas fee. Token- and network-specific requirements still apply and should be confirmed for the relevant checkout.
Funds are sent to the merchant-designated wallet rather than being held by SoloPay for a later withdrawal.
USDC is the default payment asset, but SoloPay is multi-token. Other supported tokens can be enabled per merchant, network, and payment configuration.
