Why y0
y0 is the only AI-to-crypto interface that combines all six: MCP-native, non-custodial, wallet-agnostic, full signing infrastructure, zero fees, and open-core. No other solution does all of this.
What Makes y0 Different
MCP-Native
Built for AI agents from day one. Works with Claude, GPT, Cursor, and any MCP-compatible AI tool. Not a retrofit — MCP is the core protocol.
Non-Custodial
y0 never touches your private keys. AI proposes transactions — you review and sign in your own wallet. Architectural guarantee, not a policy.
Wallet-Agnostic
Works with MetaMask, Phantom, Trust Wallet, Ledger, Rainbow — any WalletConnect wallet. Keep the wallet you already trust.
Full Signing Infrastructure
Approval queue, push notifications, full review approval — every transaction requires your explicit confirmation. The complete signing UX.
Zero Fees
Free for users and developers. y0 earns from DEX/bridge affiliate kickbacks. You pay the same price as going directly to the DEX.
Open-Core
MCP server, SDKs, and signing UI are MIT-licensed. Audit every line that touches your transactions. Backend services are proprietary.

Detailed Breakdown
Phantom MCP
Phantom wallet's own MCP server. Agents execute swaps, bridges, portfolio.
- Phantom-only. Autonomous execution — agent signs, not you.
deBridge MCP
Cross-chain bridge MCP server, 24 chains, open-source.
- Bridge-only. No portfolio, no wallet management, no approval UX.
GOAT SDK
200+ on-chain plugins for AI agents. Developer library by Crossmint ($23.6M).
- Toolkit, not product. Developer must build signing UX themselves.
Coinbase Agentic
AI agents with their own wallets via x402 protocol. Agent holds/trades autonomously.
- Agent owns wallet. Custodial by design. Coinbase ecosystem only.
Wayfinder
AI agent router with PROMPT token. "Shells" navigate blockchains.
- Token down 92%. Autonomous agents. Closed ecosystem.
Hey Anon
DeFAI protocol with autonomous agents. $20M from DWF Labs.
- Autonomous agents. Token-gated. No MCP integration.
Two Approaches y0 Avoids
The Plaid of AI-Crypto
Plaid doesn't compete with banks — it connects apps to bank accounts. y0 doesn't compete with wallets — it connects AI agents to existing wallets. Non-custodial. Wallet-agnostic. Zero secret exposure.
