NOWPayments alternative
NOWPayments is a broad crypto payment gateway with 350+ coins: customers pay a NOWPayments deposit address, and funds are forwarded to your payout wallet or kept in an optional custody balance. Payclave is narrower. It handles stablecoin checkout, verifies every payment onchain before marking it paid, and has no custody option at all.

Both services can give customers a one-time deposit address. With NOWPayments, the address belongs to NOWPayments' gateway, which tracks the payment, deducts its fee and network costs, and forwards the rest to your payout wallet or custody balance.
With Payclave, a connected-wallet payment goes straight to your settlement wallet. A Scan or copy address is created for one payment and routes the settlement token to your wallet; Payclave never holds funds along the way. In both cases Payclave verifies the recipient, token, amount, and finality onchain before reporting the invoice paid.
NOWPayments fits businesses that want to accept hundreds of coins, settle in a coin of their choice, or hold funds on the platform before converting to fiat. It also has WooCommerce and WHMCS plugins.
