## Properties

The `CoinflowWithdraw` component is intended for merchants whose end-users hold a Solana wallet balance (Coinflow's in-app wallet or a self-custodial Solana wallet). For payouts where the merchant funds payouts from a bank wire to Coinflow, see [Merchant Payouts (Coinflow Wallet)](/guides/payouts/implementation-methods/getting-started), which is API-only.
