From the repository
Connect the server to Claude, ChatGPT, or any MCP-compatible AI client. Users converse with the AI, which communicates with the blockchain through this server. For write operations (swaps and transfers), the server builds unsigned transactions that the user signs on their own device via the y0 Signing Service.
get_balance
Get native and ERC-20 token balances for a wallet address on a specific chain. If address is omitted, uses the wallet linked to the API key.
get_portfolio
Get aggregated portfolio view across all chains with USD values, per-chain breakdown, and allocation percentages. If address is omitted, uses the wallet linked to the API key.
get_price
Get current USD price and 24h change for one or more tokens. Accepts CoinGecko IDs (e.g. "ethereum") or symbols (e.g. "ETH").
get_quote
Get a swap quote with routing preview. Shows expected output, fees, and estimated gas. Does NOT execute — read-only price check.
get_gas
Get current gas prices across supported chains with USD estimates for common operations (transfer, swap, approve).
get_history
Get transaction history for a wallet address from block explorer (Etherscan/BSCScan). Supports filtering by type. If address is omitted, uses the wallet linked to the API key.
swap
Build an unsigned swap transaction. The user will approve and sign on their device — y0 never holds private keys. Requires Y0_API_KEY to be configured.
send
Build an unsigned transfer transaction. Supports native tokens and ERC-20. The user will approve and sign on their device. Requires Y0_API_KEY to be configured.

y0 Signing Service (user signs on their device)
Non-custodial by design. y0 never touches private keys. Write operations build unsigned transactions — the user always signs on their own device.
