### API Keys

Each account and sub-account on Lighter may interact with the exchange using Lighter API keys. These API keys are owned by the account and are used to sign requests when interacting with the exchange. Signed requests are verified by the exchange to confirm authorization by the API key holder and the associated account. Each account or sub-account may register up to 256 API keys.

### Sub-Accounts&#x20;

To create a Lighter account, users must have an Ethereum wallet. Using this wallet, users register a main account by signing a message that associates their Ethereum address with Lighter. Assets can then be deposited by sending a transaction from the wallet to Lighter’s smart contracts.

In addition to the main account, users may create multiple sub-accounts linked to the same Ethereum wallet.
