Payment Addressing

Payment Addressing is the mechanism through which a wallet can, on behalf of a user making a payment transaction, discover the preferred Bitcoin output script of a receiver given only their paymail handle, in the form <alias>@<domain>.<tld>.

Payment Addressing is specified across a number of BRFCs:

• Basic Address Resolution

• Sender Validation

• Receiver Approvals

• PayTo Protocol Prefix

Only Basic Address Resolution is required in order for an implementation to carry the paymail branding.
