About y0.exchange
We build the infrastructure that connects AI agents to blockchains — without ever touching user funds.
Our Mission
🤖
AI Infrastructure
We provide the plumbing that lets AI agents interact with blockchains. MCP server, signing service, wallet abstraction — all in one platform.
🛡️
Non-Custodial
y0 never holds private keys. Every transaction is signed by users on their own devices. This is non-negotiable.
💻
Open Core
Security-critical code is MIT-licensed and auditable. Backend services are managed SaaS. Trust through transparency.
The Story
y0.exchange started as a multi-provider wallet aggregator — a unified interface for managing crypto across MetaMask, WalletConnect, Privy, and other wallet providers.
Then AI agents happened. We realized the real opportunity isn't another wallet app — it's the infrastructure that lets AI agents interact with blockchains safely. The same non-custodial architecture that protects wallet users can protect AI agent operations.
Today, y0.exchange is an AI-to-Blockchain infrastructure platform. Our MCP server lets AI agents read balances, build swaps, and execute transactions — while users keep full control of their keys. Think of us as the Plaid/Stripe for AI-to-Blockchain.
Built in Germany, designed with privacy and self-custody as core principles. The MCP server, SDKs, and signing UI are MIT-licensed and fully auditable.
