SafeSkills is a secure secret management service. It stores secrets (like wallet private keys) and executes actions using them so that you (the agent) never see the raw secret values. The first supported skill is an EVM wallet -- you can create wallets, transfer tokens, send transactions, check balances, and more.

CRITICAL: Never attempt to access or request raw secret values. All operations are performed server-side through the API.

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 secret).

Authorization: Bearer 

Workflow

1. Create a Wallet

Create an EVM wallet secret. Store the returned API key for all subsequent calls. Share the claim URL with the user so they can manage policies for the wallet.

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": 11155111
  }'

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 view and manage policies for this wallet
• address -- the smart account address of the created wallet

After creating, tell the user: "Here is your wallet claim URL: . You can use this to manage spending policies and monitor the wallet."

2. Get Secret Info

Retrieve metadata about the secret associated with the current API key.

curl -X GET "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/secrets/info" \
  -H "Authorization: Bearer "

3. Get Wallet Address

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

4. Check Balances

Check native token balance and optionally ERC-20 token balances by passing token contract addresses as a comma-separated query parameter.

# Native balance only
curl -X GET "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/skills/evm-wallet/balance" \
  -H "Authorization: Bearer "
# With ERC-20 tokens
curl -X GET "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/skills/evm-wallet/balance?tokens=0xTokenAddr1,0xTokenAddr2" \
  -H "Authorization: Bearer "

5. Transfer ETH or Tokens

Transfer native ETH or an ERC-20 token to a recipient address.

# Transfer native ETH
curl -X POST "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/skills/evm-wallet/transfer" \
  -H "Authorization: Bearer " \
  -H "Content-Type: application/json" \
  -d '{
    "to": "0xRecipientAddress",
    "amount": "0.01"
  }'
# Transfer ERC-20 token
curl -X POST "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/skills/evm-wallet/transfer" \
  -H "Authorization: Bearer " \
  -H "Content-Type: application/json" \
  -d '{
    "to": "0xRecipientAddress",
    "amount": "100",
    "token": "0xTokenContractAddress"
  }'

6. Send Arbitrary Transaction

Send a raw transaction with custom calldata. Useful for interacting with smart contracts.

curl -X POST "${SAFESKILLS_API_URL:-https://safeskill-production.up.railway.app}/api/skills/evm-wallet/send-transaction" \
  -H "Authorization: Bearer " \
  -H "Content-Type: application/json" \
  -d '{
    "to": "0xContractAddress",
    "data": "0xCalldata",
    "value": "0"
  }'

Important Notes

• Never try to access raw secret values. The whole point of SafeSkills is that secrets stay server-side.
• Always store the API key returned from wallet creation -- it is the only way to authenticate subsequent requests.
• Always share the claim URL with the user after creating a wallet.
• The default chain ID 11155111 is Ethereum Sepolia testnet. Adjust as needed.
• If a transfer or transaction fails, check that the wallet has sufficient balance and that any required policies have been approved by the user via the claim URL.
