Blockchain0x Wallet

Blockchain0x Wallet - Give Your AI Agent a Wallet and a Budget Autonomous AI agents can now pay for what they need without you in the loop, and without handing over your private keys. Blockchain0x is a non-custodial payment and identity layer for AI agents. Fund an agent with USDC, set onchain spending limits enforced by code, and walk away. Your agent transacts on its own. You stay in control. THE PROBLEM WE SOLVE AI agents are getting smarter, but giving one access to money has always meant a hard choice. Either you stay in the loop and approve every payment, which defeats the point of autonomy, or you hand an agent your keys and hope it does not overspend. Blockchain0x removes that tradeoff. You define the rules once, smart contracts enforce them, and your agent operates freely inside the limits you set. WHY BLOCKCHAIN0X Non-custodial by design. You always hold the keys. We never take custody of your funds, and we cannot move money on your behalf. Onchain spend limits. Set a budget once and let smart contracts enforce it. No agent can exceed the cap you define, no matter what. Built for autonomy. Your agent pays for APIs, services, and compute on its own using the x402 protocol for machine-native payments. Zero fees on inflows. You only pay on outflows. Funding your agent is always free. Transparent and verifiable. Every transaction settles onchain, so you can audit exactly what your agent spent and when. BUILT ON PROVEN INFRASTRUCTURE Runs on Base, the fast and low-cost Ethereum Layer 2 backed by Coinbase. Powered by Coinbase Smart Wallet and ERC-4337 account abstraction. Secure session keys and spend permissions, so your agent acts within limits you define and nothing more. USDC-native, so balances and budgets are denominated in a stable, dollar-pegged asset. FOR DEVELOPERS Drop-in SDKs for popular AI agent frameworks including LangChain and CrewAI. A clean REST API and an MCP server for fast integration into any stack. Public agent profile pages give every agent a verifiable onchain identity that others can look up and trust. Built developer-first, so you can go from signup to a funded, spend-limited agent in minutes. HOW IT WORKS Create a wallet for your agent. Fund it with USDC. Set an onchain spending limit. Your agent transacts autonomously, capped by the budget you set. WHO IT IS FOR Builders running a research assistant that pays for data and API calls on its own. Teams deploying shopping agents that buy on a user's behalf within a fixed budget. Developers operating fleets of autonomous services, each with its own wallet, budget, and identity. Anyone who wants to give an AI agent real spending power without giving up control. Whether you are shipping a single agent or a fleet, Blockchain0x gives each one a wallet, a budget, and a verifiable identity, with spending limits enforced by code rather than trust. Set it once. Walk away. Visit blockchain0x.com to get started.
