3     publicKey: new PublicKey('<Wallet Public Key>'),
4     sendTransaction: (transaction: Transaction) => Promise<string>,
5     signMessage: (message: string) => Promise<string>
6   }}
7   merchantId={"YOUR_MERCHANT_ID"} // This is the merchant Id you registered an account with
8   env={"sandbox || prod"}
9   onSuccess={(...args) => console.log('Withdraw Success', args)} // Function to run when the withdraw is successful
10   blockchain={"solana"}
11   email={"user-email@email.com"} // User's email (this will be prefilled)
12 	amount={1}

KYC / KYB for Withdrawers
To complete a payout/withdraw, every Withdrawer must complete verification before they can proceed with a payout through Coinflow. Withdrawers only need to KYC the first time they withdraw and do not need to KYC again for any subsequent withdrawals.
Before you start, determine how you will KYC your users:
