HyperliquidTo Hyperliquid team: I have deployed a HyperliquidAdapter contract on Arbitrum that implements EIP-1271 isValidSignature. I want to use the contract address itself as the HL master account (directDepositMode=false). When I send approveAgent (or any action) signed by the owner EOA with signatureChainId: "0xa4b1", the API returns status: ok, but the agent is registered under the owner EOA’s HL account instead of the adapter contract’s HL account (extraAgents(adapter) stays []). On-chain EIP-1271 probe passes. Is contract-as-master + EIP-1271 supported for approveAgent / trading actions? If yes, is there a different signing format (EIP-712 typed data vs raw hash) or extra field I need?
