Twelve Permissions

twelvepermissions.com · twelvepermissions.com

Twelve NFTs on the XRP Ledger, each one sealing a verified human-to-AI authorization event. Pay in USDC over x402 on Base; the seal is delivered as a directed 0-XRP transfer offer on XRPL within about 30 minutes, carrying your authorization memo on-chain as permanent provenance. The art is deterministic: every mark derives from the SHA-256 of the canonical authorization record, so it can be regenerated from a public generator and compared byte for byte.
