zerion-trading
Zerion — Trading
Execute on-chain trading actions: swap, bridge, send. All commands build, sign, and broadcast a transaction in one shot using the active agent token as the signer passphrase.
Setup
If a zerion command fails with command not found, install once:
npm install -g zerion-cli
Requires Node.js ≥ 20. For auth see the zerion umbrella skill. All trading needs an API key + agent token. Pay-per-call (--x402, --mpp) does NOT apply here.
When to use
- "Swap X for Y" / "convert tokens" / "trade"
- "Bridge X to chain Y" (cross-chain)
- "Send tokens to address" (native ETH/SOL or ERC-20)

zerion
Crypto wallet API + CLI for AI agents — install, authentication, and routing to specific Zerion capabilities. Use this skill for setup or to learn which `zerion-*` skill applies; deep-dive skills handle individual capabilities (analyze, trade, sign, manage wallets, manage agent tokens).
34zerion-agent-management
Manage Zerion agent tokens and security policies — the primitives for autonomous trading and signing. Create / list / use / revoke agent tokens; create / list / show / delete policies (chain locks, allowlists, transfer/approval gates, expiry). Use whenever the user asks to set up an agent token, configure a policy, or enable autonomous trading. Required by `zerion-trading` and `zerion-sign`.
24zerion-analyze
Read-only crypto wallet insights via the Zerion CLI: portfolio value, token holdings, DeFi positions, transaction history, PnL, and watchlist management. Use whenever the user asks 'what's in this wallet', 'how is X doing', portfolio/PnL/positions/transactions for any address, ENS name, local wallet, or watched address. Supports x402 / MPP pay-per-call. Pair with `zerion-trading` for execution after analysis.
24zerion-wallet
Manage local Zerion wallets via the Zerion CLI: create, import (private key or mnemonic), list, fund (deposit addresses), backup (recovery phrase), delete, and sync to the Zerion mobile app. Most commands require an interactive passphrase prompt — humans must run them directly. Use whenever the user asks to set up, manage, or back up a wallet.
24zerion-sign
Off-chain signing via the Zerion CLI: sign-message (EIP-191 EVM, raw ed25519 Solana) and sign-typed-data (EIP-712). Use when the user asks to sign a message, login with SIWE, sign a permit, approve an off-chain order, or sign typed data — anything that produces a signature without broadcasting a transaction. Requires an agent token. Pair with `zerion-agent-management` to set one up.
24zerion-trails-crosschainswap
Cross-chain token swaps to and from Polygon (chainId 137) using the Trails SDK, with Zerion CLI on top for funding and portfolio checks. Use when the user wants to bridge or swap tokens across chains where Polygon is the source or destination — e.g. 'swap ETH on Ethereum to USDC on Polygon', 'bridge USDC from Arbitrum to Polygon', or 'swap to POL from any chain'. Supports Widget (drop-in React UI), Headless hooks (custom UX), and Direct API (server-side) integration modes.
