About this guide: I'm Lawrence, the writer behind supa.is. Between February and May 2026 I've published 150+ articles on supa.is across crypto and brokerage tooling — including 30+ Hyperliquid-specific guides (recent examples: Hyperliquid API Agent Wallet Setup & Permissions, Hyperliquid Builder Fee: Approve & Revoke Permissions, Hyperliquid API Error Responses: Troubleshooting Guide). The most-repeated reader question across that Hyperliquid archive is exactly how to revoke and fix API agent wallet permission errors, which is why I'm publishing this standardized guide instead of answering one-off.
When you set up an API agent wallet on Hyperliquid, you grant specific permissions to execute trades or manage vault deposits. Over time, these permissions can become stale, overly broad, or outright broken due to protocol updates. If you're facing the exact permission errors highlighted in Hyperliquid Python SDK Issue #215, you likely need to revoke and reset your agent wallet permissions.
This guide explains exactly how to safely revoke agent wallet permissions, troubleshoot the common permission errors, and reset your API setup without risking your vault deposits.
Understanding API Agent Wallet Permissions on Hyperliquid
Before revoking anything, you need to understand what an API agent wallet actually does on Hyperliquid. Unlike centralized exchanges where an API key is just a password, Hyperliquid operates on a permissioned model.
When you initialize an API agent wallet, you are essentially creating a separate on-chain entity that has been granted specific authority over your main wallet. This authority is defined by the permissions you approve. These permissions dictate what the agent can do—whether it's placing trades, modifying positions, or managing vault deposits.
The system is designed to be modular. You don't have to grant blanket access. However, this modularity introduces complexity. If a permission is not explicitly revoked, it remains active on the blockchain. If the underlying smart contract or API endpoint changes, your previously valid permission might suddenly trigger a rejection, leading to the exact errors users are reporting in the SDK community.
Why You Need to Revoke and Reset Permissions
There are three primary reasons why revoking and resetting your API agent wallet permissions becomes necessary:
- Stale Permissions: You granted access to an agent wallet for a specific bot or strategy, but that bot is no longer running. Leaving these permissions active is a security risk, as any compromised private key associated with that agent could still interact with your vault.
- Protocol Updates: Hyperliquid frequently updates its core protocols. A permission that worked under the previous version of the API might conflict with new security measures, resulting in permission denied errors.
- SDK Bugs and Glitches: As documented in GitHub issue #215, users have encountered specific permission errors when interacting with vaults. The root cause is often a mismatch between the permissions the SDK expects and the permissions currently recorded on-chain. The only way to resolve this is to revoke the old permissions and re-approve them.
How to Safely Revoke API Agent Wallet Permissions
Revoking permissions on Hyperliquid is not as simple as clicking a "delete" button in a dashboard. Because these permissions are on-chain, they must be explicitly revoked through a transaction. The process requires careful attention to detail to ensure you don't accidentally lock yourself out of your own vault.
Step 1: Audit Your Current Permissions
Before you revoke anything, you need to know what you are revoking. Hyperliquid provides documentation for vault depositors that outlines how to view current permissions. You can find the official guidelines in the Hyperliquid Docs: For Vault Depositors.
Review the list of active agent wallets attached to your main account. Identify which agents are currently active and which are no longer needed. Pay close attention to the specific permission scopes—trading, withdrawal, and vault management.
Step 2: Execute the Revoke Transaction
To revoke an agent's permissions, you must submit a transaction from your main wallet that explicitly removes the agent's authority.
This transaction typically involves interacting with the Hyperliquid smart contract directly or using a tool that can generate the correct revoke payload. If you are using the Hyperliquid Python SDK, you will need to construct a revoke action.
Step 3: Confirm the Revoke on-Chain
Once you submit the revoke transaction, wait for it to be confirmed on the Hyperliquid chain. You can verify the revocation by checking your wallet's permission list again. The agent wallet should no longer appear as an authorized entity.
If the agent wallet still appears, the revoke transaction may have failed. Check the transaction hash for any error messages. Common failure reasons include insufficient gas fees or attempting to revoke a permission that was already revoked.
Troubleshooting the GitHub Issue #215 Permission Errors
The specific permission errors highlighted in GitHub issue #215 are particularly frustrating for developers and advanced traders. The issue manifests when the SDK attempts to interact with a vault, but the on-chain permissions do not match the API's expectations.
Symptom: Vault Deposit Rejection
You attempt to deposit funds into a vault using the API, but the transaction is rejected with a generic "permission denied" or "invalid agent" error.
The Fix: This is a classic stale permission issue. The vault's smart contract has updated its permission requirements, but your agent wallet is still operating under the old rules. You must revoke the agent's vault management permissions and re-approve them.To do this:
- Revoke the agent's vault permissions from your main wallet.
- Wait for the block confirmation.
- Use the SDK to re-approve the agent's vault permissions.
- Attempt the vault deposit again.
Symptom: API Key Authentication Failures
Your API key is valid, and your IP whitelist is correct, but API calls to modify positions fail with a 401 or 403 error.

Waiting until you hit an error is the worst time to manage your permissions. Keep your vaults secure with these best practices:
1. Grant Minimum Necessary Permissions
Never grant an agent wallet more permissions than it absolutely needs. If a bot only needs to place trades, do not grant it withdrawal or vault management permissions. The principle of least privilege is your best defense against compromised keys. If an agent's private key is leaked, the damage is limited to the permissions it holds.
2. Regular Permission Audits
Set a calendar reminder to audit your agent wallet permissions every month. Look for any agents that are no longer active. If you stopped using a specific trading bot or strategy, immediately revoke its permissions. Stale permissions are a silent security threat.
3. Monitor SDK Updates
The Hyperliquid Python SDK is actively maintained. Always keep your SDK up to date. New versions often include patches for permission handling and API compatibility. The errors seen in issue #215 were largely resolved in subsequent SDK updates, but only if users were running the latest version.
4. Use Separate Agent Wallets for Different Strategies
Do not use a single agent wallet for all your trading strategies. Create a dedicated agent wallet for each strategy or bot. This way, if one strategy requires a permission reset, it does not interfere with the others. It also makes it much easier to isolate and revoke permissions if a specific strategy goes rogue.
The Role of Vault Depositors in Permission Management
If you are a vault depositor, your relationship with agent wallet permissions is slightly different. You are not just managing your own trading; you are managing how your funds are deployed by the vault operator.
According to the Hyperliquid Docs for Vault Depositors, depositors have the right to manage their vault permissions. This means you can revoke the vault operator's permissions at any time.
While this might seem aggressive, it is a critical safety mechanism. If you notice that the vault operator is making trades that violate the vault's strategy, or if you suspect a security breach, you can immediately revoke their permissions. This will freeze the vault's ability to trade your funds, giving you time to withdraw your deposits safely.
However, be aware that revoking a vault operator's permissions will likely cause the vault to stop trading. This could result in missed opportunities or even liquidations if the vault is highly leveraged. Always weigh the risks before revoking a vault operator's permissions.
Common Mistakes to Avoid When Revoking Permissions
Revoking permissions is a powerful action, but it is also irreversible. Once a permission is revoked, it cannot be restored without a new approval transaction. Here are some common mistakes to avoid:
* Revoking from the Wrong Wallet: As mentioned earlier, the revoke transaction must come from the main wallet that granted the permissions. Trying to revoke from the agent wallet will fail.
* Not Waiting for Confirmation: If you revoke permissions and immediately try to re-approve them, the transaction might fail because the chain has not yet processed the revocation. Always wait for the block confirmation. * Revoking All Permissions at Once: If you have multiple agent wallets with different permissions, revoking all of them at once can cause widespread disruption to your trading. Revoke them one by one, testing each one to ensure the rest of your setup remains functional. * Ignoring Gas Fees: Revoking permissions requires a transaction on the Hyperliquid chain. Make sure your main wallet has enough native tokens to cover the gas fees. If the transaction fails due to insufficient gas, the permissions will remain active.Securing Your Vault Deposits After a Permission Reset
After you have successfully revoked and reset your API agent wallet permissions, it is important to take additional steps to secure your vault deposits.
First, verify that the new permissions are working as expected. Place a small test trade or deposit a small amount into the vault to ensure the API is functioning correctly.
Second, update your API keys. Even though you have reset the on-chain permissions, it is a good practice to rotate your API keys. This ensures that any cached or compromised keys from the old setup are invalidated.
Third, review your IP whitelist. If you are using IP whitelisting for your API keys, make sure the new agent wallet is connecting from an authorized IP address. If the IP address has changed, update your whitelist to prevent authentication failures.
Conclusion
The permission errors highlighted in GitHub issue #215 are a common hurdle, but they are entirely resolvable. Always audit your permissions regularly, grant only the minimum necessary access, and stay up to date with SDK updates.

FAQ
How do I know if my API agent wallet permissions are stale?
If you are experiencing permission denied errors when making API calls, or if the Hyperliquid Python SDK is throwing errors related to vault deposits, your permissions are likely stale. You can also check your main wallet's permission list to see if there are any active agents that are no longer needed.Can I revoke a vault operator's permissions?
Yes. As a vault depositor, you have the right to revoke the vault operator's permissions at any time. This will freeze the vault's ability to trade your funds, allowing you to withdraw your deposits safely. However, be aware that this may result in missed trading opportunities or potential liquidations.Why does my API key work but my agent wallet permissions fail?
Your API key is just a proxy for authentication. The actual authority to execute trades or manage vaults lies in the on-chain agent wallet permissions. If the on-chain permissions are stale or corrupted, the API calls will fail even if the API key is valid.How often should I audit my agent wallet permissions?
It is recommended to audit your agent wallet permissions at least once a month. This ensures that no stale or unnecessary permissions are active, reducing the risk of security breaches and permission errors.What happens if I revoke permissions from the wrong wallet?
If you attempt to revoke permissions from the agent wallet instead of the main wallet, the transaction will fail. The permissions will remain active, and you will continue to experience the same errors. Always ensure the revoke transaction originates from the main wallet that granted the permissions.Continue with Hyperliquid
