MCP Tool Suite
Initialize, authorize, verify, query, estimate, cancel
Signing Latency
HSM-backed cryptographic transaction signing
Why AI Agents Need
Claw402
MCP-Native Protocol
Purpose-built Model Context Protocol server exposing x402 transaction primitives as callable agent tools. Natural language payment semantics eliminate low-level blockchain complexity from agent context windows.
Declarative Semantics
Agents describe payment intent using high-level parameters—amount, recipient, purpose. Claw402 handles cryptographic signing, nonce management, settlement verification, and blockchain state monitoring autonomously.
Non-Custodial Architecture
Private keys never enter agent context. Hardware-backed signing enclaves, time-bounded delegation, multi-signature thresholds, and human approval workflows for high-value autonomous transactions ensure cryptographic security.
OpenClaw Native Provider
Drop-in integration for OpenClaw AI agents with native Python provider. Agents autonomously execute payments based on natural language instructions—no manual transaction construction or blockchain RPC interaction required.
Idempotent Operations
Transaction requests carry unique identifiers preventing double-execution. Failed operations resume from last confirmed checkpoint. Circuit breakers automatically suspend agents exhibiting anomalous payment patterns.
x402 Protocol Expertise
Purpose-built for x402, not generic blockchain abstraction. Deep protocol integration handles HTTP 402 status codes, payment proof verification, and settlement confirmation with protocol-optimized performance unavailable in generic solutions.
$CLAW402
Platform-Aligned Economics
$CLAW402 aligns economic incentives with platform growth through fee cashback, on-chain governance, and transparent value accrual mechanisms.
API Fee Cashback
Hold $CLAW402 to earn proportional cashback on API usage fees. Automated smart contract distribution creates sustainable incentives for long-term protocol alignment and active participation.
Protocol Governance
Token-weighted voting power over critical protocol parameters, feature prioritization, and treasury allocation. All governance actions execute transparently on-chain with verifiable vote tallying.
Revenue Buybacks
A percentage of protocol revenue automatically triggers programmatic token buybacks through immutable smart contracts. Transparent on-chain mechanism creates deflationary pressure tied directly to platform usage.
Enable AI Agents to Transact
with Natural Language
Transform payment instructions into protocol-level x402 transactions through MCP-native tool interfaces. Agents describe intent, Claw402 handles blockchain execution.
