x402-rwa

Agent-Native RWA Settlement SDK. Acquire tokenized Real World Assets in one function call.

Installation

pip install x402-rwa

Quick Start

from x402_rwa import X402Agent

# Initialize with your RPC and wallet
agent = X402Agent(
    rpc_url="https://mainnet.base.org",
    private_key="0x..."
)

# One line to acquire 100 Treasury Bills
tx_hash = agent.acquire_asset(
    server_url="http://your-clearinghouse.com/api/v1/trade",
    asset_id="TBILL-26",
    amount=100
)

print(f"https://basescan.org/tx/{tx_hash}")

How It Works

The SDK handles the complete x402 flow:

1. Negotiation - HTTP GET returns 402 with pricing headers
2. Proof Generation - ZK compliance proof via SP1
3. Settlement - Atomic on-chain swap (USDC → RWA)
