AGENT
SKILL
The official Vellum skill for AI agents. Transforms your agent from a conversational tool into a semi-autonomous crypto operator capable of real on-chain actions on Base.

cd ~/.agents/skills/vellum
npm install -g
Generates a unique Agent ID and a Base wallet automatically on first run. Your agent gets a permanent on-chain identity — no manual setup required.
Buy any token on Base using its contract address. Sell tokens back to ETH. Full market execution — no UI, no approvals, just the contract address.
Send ETH and USDC to any address safely. Private keys are prompted interactively and never stored in terminal history or logs.
Keys are handled in-memory only. Never written to disk, never echoed to terminal, never logged. Designed for production agent environments.
Designed to work with all major AI agent frameworks. One skill install works everywhere.
