Every rail. Every chain. Mandates that hold.
From cart mandate to cross-chain receipt — on one open coordination surface.
The payment surface for the AI age.
MPP integration
Machine Payments Protocol co-authored by Stripe and Tempo. HTTP 402 challenge/credential/receipt with session management.
x402 facilitator
Coinbase's HTTP 402 payment protocol. EIP-3009 transferWithAuthorization. CDP facilitator for verify/settle. Stablecoin-native.
AP2 mandates
Cart-mandate validation against TDIP DelegationScope and runtime SpendingPolicy. Three-axis ceiling enforced before settlement.
Visa TAP + Mastercard
Trusted Agent Payments and Mastercard Agent Pay — card rails for agents with cryptographic mandate validation.
Tempo + Stripe
Direct Tempo participation with EIP-155 signing. Stripe Payment Intents for fiat onramps. HMAC-SHA256 webhook verification.
ERC-7579 validators
Spending limit validators on-chain — per-tx and rolling-window daily ceilings enforced at signing time, not after.
Cross-chain settlement
ERC-7683 cross-chain intents. Wormhole NTT for stablecoin transfers. LayerZero V2 with Tenzro DVN for messaging.
Channels and escrow
Off-chain micropayment channels for high-volume flows. On-chain escrow for high-value coordination. Atomic dispute resolution.
Compliance posture
TDIP KYC tiers (Unverified / Basic / Enhanced / Full). Credential-gated upgrades. Verifiable Credentials over W3C VC.
From mandate issuance to settlement.
- 01Issue identity and mandateProvision a TDIP DID for your customer (human) and their agent (machine). Bind a DelegationScope — max per-tx, daily spend, allowed operations, time bound.
- 02Install validator modulesInstall ERC-7579 SpendingLimit and SessionKey validators on the smart account. Enforced at signing time by the EntryPoint.
- 03Accept agent paymentGate a resource with HTTP 402. Agent submits a credential against the challenge — MPP session, x402 stateless, or AP2 cart.
- 04Validate three-axis ceilingPaymentGateway verifies credential. IdentityPaymentBinder enforces TDIP scope. SpendingPolicyResolver enforces runtime daily window.
- 05Settle and routeSettlement engine moves TNZO, opens a channel, releases escrow, or routes to Visa/Mastercard. Cross-chain via bridge router.
- 06Issue receiptSigned receipt with SHA-256 commitment. Optional on-chain anchor. Mandate hash bound to TDIP DID. Replay-safe nonce.
