Overview

Aster uses an API signer model for programmatic trading. Unlike Hyperliquid’s agent wallet (which Tangerine generates for you), you must create the API signer key yourself from Aster’s dashboard and then import it into Tangerine.

​
Step 1 — Create an API Signer on Aster

  1. Go to Aster’s trading interface
  2. Connect the same wallet you use on Tangerine
  3. Navigate to Account → API Keys (or equivalent in Aster’s UI)
  4. Click Create API Key / Generate Signer
  5. Aster will display your signer address and private key
Save the private key immediately. Aster may only show it once. If you lose the private key, you will need to generate a new signer.

​
Step 2 — Import into Tangerine

  1. Return to Tangerine and open Settings → Aster
  2. Click Import API Key
  3. Paste your signer address (0x…)
  4. Paste your private key
  5. Sign the encryption message with your main wallet
Tangerine encrypts the private key using the same 3-layer key storage it uses for Hyperliquid. The raw private key is never stored in plaintext.

​
Step 3 — Verify

After importing, Tangerine will verify the signer key can authenticate with Aster. If successful, the Aster platform will show as Ready in your platform list and you can start trading.

​
Key Security

Your Aster private key is encrypted in your browser using your wallet signature as the encryption password. See Key Management for details. If you suspect your key is compromised:
  1. Go to Aster’s dashboard and revoke the API signer
  2. Create a new API signer
  3. Re-import the new key in Tangerine via Settings → Aster → Replace Key

​
Rotating Your Key

To replace an existing Aster signer key:
  1. Create a new API signer on Aster (don’t delete the old one yet)
  2. In Tangerine, go to Settings → Aster → Replace Key
  3. Import the new signer address and private key
  4. After confirming it works, revoke the old signer from Aster’s dashboard
