ON-CHAIN ATTESTATION LAYER

NFT Attestation
& Verification.

OPTKAS uses non-fungible tokens not as speculative assets, but as cryptographic proof primitives — settlement receipts, compliance attestations, asset verifications, and bond certificates anchored immutably to public ledgers.

Settlement Proof NFTs

XRPL

Immutable on-chain receipts minted at settlement finality. Each NFT encodes the transaction hash, counterparty identifiers, settlement amount, and timestamp — providing cryptographic proof of DVP execution.

Compliance Attestation Tokens

XRPL + Stellar

KYC/AML attestation NFTs issued to verified institutional participants. These non-transferable tokens serve as on-chain compliance records, enabling automated trustline activation and deal-room access.

Asset Verification NFTs

XRPL

Tokenized proof-of-asset NFTs linking physical collateral to on-chain state. Each NFT references UCC-1 filing numbers, appraisal data, and custody chain documentation for RWA-backed facilities.

Attestation Architecture

OPTKAS NFTs serve as the immutable evidence layer of the capital stack. Unlike conventional NFTs, these tokens are purpose-built institutional primitives designed for compliance, audit, and settlement verification.

Each NFT is minted with embedded metadata containing SHA-256 hashes of source documents, counterparty identifiers, and settlement state transitions — creating an unbreakable chain of custody from asset origination to final settlement.

Compliance Attestation Tokens are non-transferable (soulbound), ensuring KYC/AML verification cannot be passed between parties. This maintains regulatory integrity while enabling automated deal-room access and trustline activation.
