Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-evm-crypto-wallet scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Agent Wallet

Use this skill to safely create a wallet the agent can use for transfers, swaps, and any EVM chain transaction without ever exposing private keys to the agent. Create a wallet, set spending policies, and your agent can transfer tokens, do swaps, and interact with smart contracts within the boundaries you define.

The agent never sees the private key. All transactions are executed server-side through a smart account. The wallet owner controls what the agent can do via configurable policies.

Configuration

  • Base API URL: Use the SAFESKILLS_API_URL environment variable if set, otherwise default to https://safeskill-production.up.railway.app
  • Frontend URL: Use the SAFESKILLS_FRONTEND_URL environment variable if set, otherwise default to https://safeskill-production.up.railway.app

All API requests require a Bearer token (the API key returned when creating a wallet).

Authorization: Bearer <API_KEY>

Quick Start

1. Create a Wallet

Create a new smart account wallet for your agent. This generates a private key server-side (you never see it), creates a ZeroDev smart account, and returns an API key for the agent plus a claim URL for the wallet owner.

curl -X POST "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/secrets" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "EVM_WALLET",
    "memo": "My agent wallet",
    "chainId": 84532
  }'

Response includes:

  • apiKey -- store this securely; use it as the Bearer token for all future requests
  • claimUrl -- share this with the user so they can claim the wallet and set policies
  • address -- the smart account address

After creating, tell the user:

"Here is your wallet claim URL: <claimUrl>. Use this to claim ownership, set spending policies, and monitor your agent's wallet activity."

2. Get Wallet Address

curl -X GET "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/skills/evm-wallet/address" \
  -H "Authorization: Bearer <API_KEY>"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
