In some cases, the allowance might be insufficient, or you may want to revoke it fully. Tools like revoke.cash wouldn't support this kind of allowance (but also, no one can take esALB from you). To fix allowance issues, for now you need to manually approve usage on Basescan. To do so, head over to this link: **Click 'Connect to Web3' to connect your wallet.**
Then, find the "approveUsage" function and fill the following parameters: * UsageAddress: 0xd3968A4a07d64C6E16982d45191b9A09a261Ec88 * Amount: 1000000000000000000000000000 Usage Address is the address of our EsMaster, a contract for farming with esALB and other locked tokens. The amount is equivalent to 1 billion ALB, which is more than the total supply and should be more than enough for any approval. To revoke approval, just set the amount to 0 Next, click on 'Write', confirm the transaction, and your allowance should be fixed!

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.alienbase.xyz/escrowed-alb-esalb/changing-allowance.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
