Hyperliquid support on Turnkey

Address derivation

Turnkey supports Hyperliquid (EVM) address derivation with ADDRESS_TYPE_ETHEREUM. This address format is valid across all of the Hyperliquid ecosystem (HyperCore and HyperEVM).

Transaction construction and signing

To construct and sign a Hyperliquid (EVM) transaction with Turnkey, we offer:

• @turnkey/viem: contains a createAccount method to create a Turnkey-powered custom account which Viem can use seamlessly.
• @turnkey/ethers: contains a TurnkeySigner which implements Ethers’ AbstractSigner interface. See Ethers docs.

Transaction parsing, policies, and signing

Please refer to our Ethereum network page for details on transaction parsing, policies, and signing, as Hyperliquid shares the same EVM architecture. However, HyperCore notably uses EIP-712 messages to perform various actions. More information on defining EIP-712 policies, see here. Additionally, top-level policy details can be found here.

For an example of how to construct a policy targeting such Hyperliquid-specific EIP-712 messages, see here.
