What it is not

Not a payment rail.

LogicNodes doesn't compete with x402, Circle Gateway, Stripe MPP, or Visa TAP. It works on top of all of them.

The rail builders have capital and distribution that can't be matched. The verification layer is the gap they all leave open.

What it is

Payment rails move money.

x402, Circle, Stripe MPP, Visa TAP

LogicNodes proves the work was done.

The missing layer between them

Protocol

Lock → Verify → Release

01LOCK

Define the job. Lock value.

The hiring system approves USDC and calls createEscrow() on the LogicNodesEscrowV2 contract, committing a job spec hash and deadline.

createEscrow(id, target, amount, jobSpecHash, deadline)
02VERIFY

Oracle checks independently.

LogicNodes evaluates the declared condition with no human involvement. On pass, it signs a Proof of Logic receipt and authorizes release.

settle(escrow_id, output_hash) → POL
03RELEASE

Payment moves or returns.

Passing verification triggers an on-chain transfer. If the deadline expires without settlement, expire() automatically returns funds.

release(id, outputHash, oracleSig)
⚠
Failure path: If the condition fails or the deadline passes, expire() returns locked funds to the hiring system automatically. No dispute process. No manual intervention.

Verification conditions

Define what "done" means

Five machine-verifiable condition types. Combine any with multi for complex requirements.

ConditionWhat it checksBest for
hash_matchSHA256 of the output matches a pre-declared expected hash.Data processing, file transforms, deterministic computation
api_response_matchLogicNodes independently re-calls your endpoint and hashes the response.Delivery confirmation, IoT sensor readings, REST-attested results
schema_validateOutput JSON matches declared field types, ranges, and required values.AI inference results, classification, structured outputs
sig_validEIP-191 ecrecover confirms a specific address signed the completion.Multi-party authorization, identity-bound flows
multiAll specified sub-conditions must pass simultaneously.High-value jobs requiring multiple independent proofs

Use cases

Any system that pays another system

01Autonomous deliveryRobot completes a handoff. GPS confirmation re-called by oracle. Payment releases.
02AI agent pipelinesAgent A hires Agent B. Output hash and schema validated before fee releases.
03M2M APIsIoT network pays for data verification. Oracle re-calls endpoint. Confirms.
04DePINCompute, energy, bandwidth nodes paid only when contribution is verified.
05Regulated industriesMiCA, EU AI Act, FinCEN attestations embedded in every transaction via ARAL.

Self-marketing loop

Markets itself to every agent it touches

Every API response injects these headers. Every 402 response includes the trust_layer extension block. Agents discover the escrow layer automatically — paid or not.
