Agent Wallet Skills

Purpose

Use this skill as the main entrypoint for wallet setup workflows.

Runtime Requirements

• Runtime: Node.js 18+ (or equivalent TS/JS runtime)
• Required package: viem
• Network access: RPC endpoint for the target chain
• Secret storage: vault, key manager, or encrypted secret store

Required Secrets / Inputs

• RPC_URL for chain reads/writes
• SEED_PHRASE only when user explicitly chooses mnemonic import/signing
• PRIVATE_KEY only when user explicitly chooses private key import/signing
• Agent must ask for confirmation before reading env-based secrets

Wallet Type -> Skill Location Map

• Local wallet (generate/import with seed phrase or private key): local-wallet/SKILL.md
• Check native/token balance (viem): local-wallet/balance/SKILL.md
• Send transaction with existing wallet (viem): local-wallet/send/SKILL.md

Routing Logic

1. Check if the agent already has a wallet configured:

- if wallet exists, use existing wallet flow - if wallet does not exist, run wallet generation flow (step 2)

1. Wallet generation flow (no existing wallet):

- ask preferred method: seed phrase or private key import - if user does not provide a method, default to generating a new seed phrase wallet - generate/import with viem account helpers in local-wallet/SKILL.md - derive address/public key and persist via the project's secure secret mechanism

1. Identify the wallet input type from the user request:

- mnemonic / seed phrase words - hex private key string - request to generate a new wallet

1. Route by wallet type to the mapped location:

- seed phrase -> local-wallet/SKILL.md - private key -> local-wallet/SKILL.md - check balance -> local-wallet/balance/SKILL.md - send transaction -> local-wallet/send/SKILL.md

1. If input type is unclear, ask one focused question:

- "Do you want to use a seed phrase or a private key?"

No Wallet Exists (Viem Flow)

When the agent has no wallet configured, create one with viem before continuing.

Preferred default (generate new private key wallet)

import { generatePrivateKey, privateKeyToAccount } from 'viem/accounts'

const privateKey = generatePrivateKey()
const account = privateKeyToAccount(privateKey)

// Persist privateKey via secure secret storage only (env vault, key manager, etc.)
// Use account.address as the agent wallet address.

Optional seed phrase path

• If user explicitly asks for seed phrase-based setup, follow local-wallet/SKILL.md seed phrase flow.
• Derive the account/address and store secret material in secure secret storage.

Required checks after generation

• Wallet address exists and is valid format for the target chain.
• Secret material is stored securely and never echoed in plaintext.
• Agent metadata references the new wallet address for future operations.

Shared Safety Rules

• Never print full seed phrases or private keys in outputs, logs, or summaries.
• Mask secrets when showing examples (for example ab12...9f).
• Prefer offline generation/import steps where possible.
• Remind users to back up secrets in a secure location.
• Default to read-only actions until user explicitly asks to send/broadcast.
• If chain is not provided, default to a testnet and state that choice.
• Never broadcast immediately after simulation without explicit confirmation.

Completion Requirements

Before finishing:

• confirm wallet address/public key was derived successfully
• confirm secret material was not exposed in plain text
• if wallet was missing, confirm a new wallet was created and stored securely
• provide next action (backup, test transaction, or network config)

Standard Response Contract

Return this structure across all wallet skills:

• action: generate | import | balance | send
• chain: chain id/name used
• address: active wallet or queried address
• txHash: transaction hash when available, else null
• status: success | failed | needs_confirmation
• next_step: one clear follow-up action
