Payments Flow

Paymail Capability Extensions

The SPV Wallet uses Paymail capabilities to publicly reveal their ability to interpret SPV transaction data.

What is Paymail?

It's a service discovery mechanism for counterparty web APIs. It allows users to pay something which looks like an email address, but under the hood resolves a specific endpoint for a wallet to use for payment negotiation. [e-mail] -> https://domain.tld/api/some/specific/endpoint
