send21 is a non-custodial crypto-payment tool for creating payment drafts and hosted pay links. A sender enters a payment request, selects the supported asset and shares the resulting link with the person or business expected to pay. The recipient connects and signs with their own wallet; send21 says it does not hold private keys, custody balances or broadcast a transaction on either side’s behalf.
The product is designed for direct wallet-to-wallet settlement rather than card acquiring or fiat payout. Its public materials describe a draft as a structured request that can include an amount, recipient wallet, expiry and payment details. The requester shares the link; the payer reviews it and confirms the on-chain transfer from a compatible wallet. It suits merchants, freelancers and crypto-native businesses that want payment links without placing funds in a platform account.
The official send21 site identifies Bitcoin (BTC), USD Coin (USDC) and Tether (USDT) as supported assets. Cryptwerk records only those directly named coins; it does not infer support for every network or wallet that could be connected to a link. The listing is classified as a Payment gateway because the documented product creates payment requests for receiving crypto, not as Pay with crypto: there is no stated crypto-to-fiat bill-payment or merchant-fiat-settlement flow.
For any payment, both parties should verify the recipient wallet, asset, network, amount, expiry and transaction details in the live interface.
