EIP-712

Orderly Network relies on the EIP-712 standard to authenticate wallets and accounts for critical actions, such as:

  • Account creation

  • Orderly key addition

  • Withdrawal requests

For these actions, wallet owners will need to sign specific messages from their wallet and pass the signature through the REST APIs to complete the action. The following sections describe the steps needed to complete these actions.

For other actions, such as calling trading-related RESTful APIs, a successful Orderly Key generation is required in order to use it via API authentication.

​
Domain

Orderly Network utilizes the following EIP-712 domain and types for the registration, access key, withdrawal and settle PnL processes. Note that chainId will be the id of the chain connected, which must be supported by Orderly Network.

​
Off-chain Domain

The Registration and AddOrderlyKey types are entirely processed off-chain, which is why the verifyingContract is set to 0xCcCCccccCCCCcCCCCCCcCcCccCcCCCcCcccccccC.

{
    "name": "Orderly",
    "version": "1",
    "chainId": chainId,
    "verifyingContract": "0xCcCCccccCCCCcCCCCCCcCcCccCcCCCcCcccccccC",
}

​
On-chain Domain

Any other type uses the on-chain domain. The address for the Ledger contract on the Orderly L2 chain can be looked up here.

{
    "name": "Orderly",
    "version": "1",
    "chainId": chainId,
    "verifyingContract": ledgerContractAddress,
}

​
Message Types

The message types are required for the EIP-712 algorithm to do a proper signing. Here is a list of all message types as JSON:

Orderly key

Orderly Network uses the ed25519 elliptic curve standard for Orderly keys. Users can generate Orderly keys using any public ed25519 libraries and then be added to any account through the REST API. An Orderly key is necessary to perform API authentication.

Orderly keys can have different scopes. A read scope API can access all private read-only APIs, and a trading scope can, in addition, access all order APIs (create order, batch create order, edit order, cancel order, cancel order by client_order-Id, cancel orders in bulk, batch cancel orders, batch cancel orders by client_order_id).

Orderly keys also have expirations for security reasons. The maximum allowed expiration of an Orderly key is 365 days.

Follow the following steps to add a new Orderly key on Orderly Network:

1

Generate an ed25519 key-pair

Any public ed25519 library can be used (such as this one).

2

Obtain signature from EIP-712

Sign a message from the wallet in the following format using the EIP-712 standard and obtain the signature

{
    "brokerId": "woofi_dex",
    "chainId": 80001,
    "orderlyKey": "ed25519:HqN9uKJioHjAJZbadgQRGzq2e7huKg6foCyNY43hWbCk",
    "scope": "trading",
    "timestamp": 1685973094398,
    "expiration": 1686081094398
}

where:
