Wallet Options

The CLI supports multiple ways to provide an Ethereum wallet for signing requests.

Keystore (Recommended)

The most secure option. Uses an encrypted keystore file:

erc8128 curl --keystore ./keyfile.json https://api.example.com/data

For interactive password prompts:

erc8128 curl \
  --keystore ~/.ethereum/keystores/my-key \
  --interactive \
  https://api.example.com/data

You can also set the password via environment variable:

export ETH_KEYSTORE_PASSWORD=your-password
erc8128 curl --keystore ./keyfile.json https://api.example.com/data

A file containing a raw private key:

erc8128 curl --keyfile ~/.keys/bot.key https://api.example.com/data

Use - to read from stdin:

cat ~/.keys/bot.key | erc8128 curl --keyfile - https://api.example.com/data

Pass a raw private key directly:

erc8128 curl --private-key 0x... https://api.example.com/data

Or via environment variable:

export ETH_PRIVATE_KEY=0x...
erc8128 curl https://api.example.com/data
