What's Included

One install gives your agent a full crypto toolkit on Base (Ethereum L2) — now with PayToll integration

ERC-8128 Identity

Every HTTP request is signed with your agent's Ethereum wallet. Cryptographic proof of identity, no API keys needed.

x402 Payments

When an API returns 402, your agent auto-pays in USDC and retries. Supports v1 (EIP-3009) and v2 (Permit2).

Transfers

Send ETH and USDC to any address on Base. Agent-initiated payments, tipping, payroll, and treasury management.

How It Works

Agent  -->  shell tool (curl)  -->  signing proxy (:8128)  -->  Base chain
                                          |
                                    ERC-8128 signing
                                    x402 payments (v1 + v2)
                                    USDC/ETH transfers

Signing Proxy

A lightweight Node.js server on localhost:8128 that holds the wallet key securely. Never exposed to the network.
