# Blockchain / Wallet Address Configuration

* Merchants must configure their wallet addresses to receive payments from customers.
* Presently, transactions are permitted through SUI, Solana, Blast, Polygon, and BNB wallets.
* The default coins SOL-USDC & SOL will automatically be included in the Solana wallet.
* Merchants can disable/enable the specific wallet.
* Please note that merchants cannot generate a Checkout link without first adding their wallet address.
