How It Works

AARON splits biometric authentication into four phases — capture, proof, payment, and access.

1. Private Gaze Audit

AARON captures biometric tensors on-device using MediaPipe face landmarks. Raw iris data never leaves the validator node. The Agentive Gaze Tensor (AGT) system classifies eye movement into three tensors: Cognitive (COG), Emotional (EMO), and Environmental (ENV). AGT performs the Web4 actions that power JETT Auth.

2. Opaque Proof to Solana

A 32-byte verification hash is computed from the gaze sequence, hold durations, and session nonce. This hash is submitted on-chain via the CSTB DePIN program. Validators confirm the proof without ever seeing raw biometric data.

3a. x402 Unlocks Action

Payment attestation triggers domain registration, NFT mint, or agent delegation via micropayment. The x402 protocol settles OPTX payments atomically alongside the biometric proof.

3b. Machine-to-Machine Payments (MPP)

The MPP protocol enables autonomous agents to pay for AARON attestation services using USDC. Agent wallets (like JOE) submit x402 micropayments that are atomically settled alongside proof verification. Each agent payment creates an AgentAcquisition PDA on-chain, linking the payment to the authenticated user.

3c. USDC Bridge: XRP to Solana

Cross-chain settlement bridges USDC between XRP Ledger (via Xahau hooks) and Solana. Agent payments originating on XRP are bridged to SOL-side USDC and deposited into the vault program's donate_usdc_agent instruction. The bridge uses Wormhole/DeBridge for trustless cross-chain transfers, with Xahau hooks triggering automatic settlement.

3d. Vault NFT Receipts

Every donation (SOL or USDC) generates an on-chain DonorReceipt PDA. The receipt records:

• Donation amount
• JTX tokens entitled at $8/token
• OPTX multiplier (2x in Phase 1)
• Payment method
• Claim status

These receipts serve as NFT claim tickets for the OPTX airdrop. Vault PDA: CQmBrff4a9MouY4eQTAPKXKprtvfHZDNSkNCQhRR38tP.

3e. Xahau Hooks (XRP Settlement)

Xahau hooks on the XRP Ledger enable programmable settlement for cross-chain payments. When an agent or user initiates a payment on XRP, the hook automatically:

1. Validates the payment amount against USDC rates
2. Triggers the bridge to Solana
3. Calls donate_usdc_agent on the vault program

This enables XRP-native users and XRP liquidity pools (XAH/mXRP/MAG/RLUSD) to participate in the vault.

4. Staked Tiers via Layer 3

$OPTX staking determines access tiers. Higher stake = lower x402 fees + priority compute.
