Api Endpoint

SCVD General Store

A Sheaf of Attestations. REQUIRES ?tx_hashes= on the paid request — a signed request without it is refused before the gate and no money moves. Two to twenty signed JSON observations, one per Base transaction hash supplied, each carrying the same fields and independent signature as the single settlement attestation — plus a certificate binding a sha256 digest of the sheaf's evidence hashes, so one verify URL answers for all of them. Instant. Full listing: https://scvd.store/m…
