- Auto-provisioned server wallets — create an agent and its wallet in one call, or bring your own EVM/Solana address. - Spend policies — cap agent budgets per period, with hard-block or advisory enforcement. - Interaction policies — server-side guardrails on contracts, methods, recipients, and amounts that agents cannot bypass. - Autonomous transactions — queue, claim, sign, and broadcast on-chain intents from MCP clients. - ERC-8004 on-chain identity — register agent identity with a server or bring-your-own signer. - MCP-native & x402-aware — works with Cursor, Claude Desktop, and CLI; budgets paid MCP tools.

- Node.js = 18 - API Key from the Abstraxn Dashboard
