Register a Sila handle, link a bank account, and initiate an ACH transfer via Sila Money

Steps

1. Generate an Ethereum wallet keypair for both your app and the end user; Sila uses blockchain-based message signing (secp256k1) for authentication rather than traditional API keys alone
2. Register a user handle: POST /0.2/register with header.auth_handle (your app handle), message: 'header_msg', and the user's personally identifiable information (name, address, SSN last 4 or full, date of birth, email, phone) plus their Ethereum address; sign the request header with your app private key
3. Request KYC: POST /0.2/request_kyc with the user handle and app auth; poll POST /0.2/check_kyc until kyc_status is PASSED
4. Link a bank account: POST /0.2/link_account with the user handle, Plaid public_token (via Plaid Link) or direct account/routing numbers; both the app and user private keys must sign the request
5. Issue an ACH debit: POST /0.2/issue_sila with the user handle, amount (in Sila token units where 1 Sila = $0.01 USD), and account_name; this initiates an ACH pull and mints equivalent Sila tokens into the user's wallet
