Required before placing any order, close, or TP/SL.

1. Run the following to find your onchainos signer address:
   bash

   # Place any order preview (no --confirm) and check the "User" in any HL error response,
   # or run a dry-run and note the recovered address from exchange errors.
   hyperliquid order --coin ETH --side buy --size 0.001 --confirm --dry-run

   The HL exchange will return an error like:

   "User or API Wallet 0xYOUR_SIGNER_ADDRESS does not exist."

   That

   0xYOUR_SIGNER_ADDRESS

   is your actual HL signer.
2. Go to https://app.hyperliquid.xyz → Settings → API Wallets
3. Click Add API Wallet and enter

   0xYOUR_SIGNER_ADDRESS

4. Sign the approval with your connected wallet

cancel

Note: This is only needed if you are using onchainos with an AA (smart contract) wallet. If your onchainos wallet is a plain EOA, the signer and account addresses are the same and no extra setup is required.

Write operations require

WARNING: Perpetual futures are high-risk derivative instruments.

• Perpetuals use leverage — losses can exceed your initial margin
• Positions can be liquidated if the liquidation price is reached
• Always verify the

  liquidationPrice

  before opening a position
• Never risk more than you can afford to lose
• Funding rates can add ongoing cost to long-running positions
• Hyperliquid L1 is a novel chain — smart contract and chain risk apply
• All on-chain write operations require explicit user confirmation via

  --confirm

• Never share your private key or seed phrase
• All signing is routed through

  onchainos

  (TEE-sandboxed)
• This plugin does not support isolated margin configuration — use the Hyperliquid web UI for advanced margin settings

• Spot token swaps (use a DEX swap plugin instead)
• Cross-chain bridging (use a bridge plugin)
• Automated trading bots or high-frequency trading without explicit user confirmation per trade
• Bypassing liquidation risk — always maintain adequate margin
