What it does

• Atomic wallet-pay split on Solana
• Atomic wallet-pay split on Base
• Exchange pay matched by a unique amount
• Prepaid fee credit for exchange payments
• Four chains and two stablecoins, addresses verified at the issuer
• Invoice status machine
• HMAC-signed webhooks with retries and dead letter
• Append-only fee-credit ledger

You need

• Node.js 20.6 or newer (Node 22 for the Solidity contract tooling) and pnpm 10
• A server you control for the API and the SQLite file - shared hosting is not enough
• Your own Solana RPC endpoint and, for Base, your own EVM RPC endpoint. No key is shipped with the source
• Your own wallet address to receive the operator fee, and one wallet address per merchant
• To deploy MikodesPayRouter yourself on Base before Base wallet pay can be switched on
