x402 Payments for
OpenClaw agents
ClawFirst enables AI agents to execute cryptocurrency transactions on x402. Declarative payment semantics. Non-custodial security. Production-ready.
from openclaw import Agent
from clawfirst import X402Provider
# Enable autonomous payments
agent = Agent(
providers=[X402Provider()]
)
# Agent executes payments via natural language
agent.run("Pay invoice #402 for $250 USDC")Built for autonomous agents
ClawFirst eliminates the friction between AI agents and economic infrastructure through MCP-native tooling.
MCP-Native Protocol
Purpose-built Model Context Protocol server exposing x402 transaction primitives as callable agent tools.
Declarative Semantics
Agents describe payment intent using high-level parameters. ClawFirst handles cryptographic signing, nonce management, and settlement verification.
Non-Custodial Architecture
Private keys never enter agent context. Hardware-backed signing enclaves and multi-signature thresholds ensure cryptographic security.
OpenClaw Native Provider
Drop-in integration for OpenClaw AI agents with native Python provider for autonomous payment execution.
Idempotent Operations
Transaction requests carry unique identifiers preventing double-execution. Failed operations resume from last confirmed checkpoint.
x402 Protocol Expertise
Purpose-built for x402 with deep protocol integration for HTTP 402 status codes and payment proof verification.
Integrate in minutes
Transform natural language into x402 transactions. Drop-in integration for OpenClaw, LangChain, and custom agents.

}Meet the Creator
ClawFirst is a personal project by Daryl, built from a genuine fascination with what happens when AI agents meet real-world money.

Hey! I'm Daryl, and ClawFirst is my experiment in answering a question that keeps me up at night: what if AI agents could actually handle money on their own?
I've been tinkering with software for years, and this project combines two things I find genuinely fascinating, AI that can make decisions and blockchain that can execute them. No big team, no corporate backing, just me building something I want to see exist.
ClawFirst started as a side project to solve a real problem: giving AI agents the ability to transact autonomously without compromising security. It's still very much a work in progress, but that's the fun part.
