Làm thế nào để thu hồi hợp đồng hoán đổi 1inch cho XSGD sang USDC?

Question

Gần đây tôi đã thử hoán đổi XSGD (Polygon) sang USDC (Polygon) bằng 1inch và chấp nhận hợp đồng thông minh. Tôi đã đặt giới hạn được phê duyệt là 500 XSGD, hoán đổi toàn bộ số tiền, nhưng bây giờ muốn biết cách xác định và có khả năng thu hồi hợp đồng nếu cần. Tôi đã sử dụng các công cụ như unrekt và revoke nhưng không thể tìm thấy bất kỳ hợp đồng nào trong ví của mình. Làm thế nào để người ta thường tiếp cận việc thu hồi các hợp đồng thông minh như vậy?

Your wallet client should show which connections are current. You can also use services like revoke to identify and revoke permissions. If you completed the swap using the approved limit, its likely that the contract permissions have been used, and there might not be an active contract remaining to revoke. It sounds like everything went through as intended.

Revoking smart contract approvals after a swap is a good security measure, but in your case, it’s possible that there is no active contract left to revoke. Since you set an approval limit of 500 XSGD and swapped the full amount, the contract may have already used the entire allowance, leaving nothing to revoke. However, if you want to double-check, there are ways to verify whether any active permissions remain. First, check your wallet’s built-in permission manager. Some wallet clients, like MetaMask, allow you to view which contracts currently have access to your tokens. Open your wallet settings and look for a section labeled Connected Sites or Token Approvals. If 1inch or any other contract still has approval for XSGD, it should appear there. If you don’t see any active approvals, it’s likely that the contract permissions were fully used during the swap. Next, use a blockchain approval checker like PolygonScan’s Token Approval Tool. Enter your wallet address and look under ERC-20 approvals for XSGD. If you see an active allowance granted to 1inch’s smart contract, you can revoke it directly from this tool. Since approvals persist even if you have zero balance, this step ensures there isn’t an open permission that could be used again in the future. Another useful tool is Revoke.cash. Connect your wallet, select the Polygon network, and review all token approvals linked to your address. If an XSGD approval appears, you’ll see the spending limit and the contract associated with it. Clicking Revoke will remove the contract’s access to your funds. If no active approvals are found, then 1inch does not have ongoing permission to use your XSGD. If Revoke.cash doesn’t show any approvals, try Unrekt.net, which scans for active token allowances across multiple contracts. Connect your wallet, switch to Polygon, and check if 1inch has any remaining permissions. If nothing appears, that confirms your approval has already been used and no further action is needed. If none of these tools show an active contract, but you still want to manually revoke approvals, you can do so via the 1inch smart contract on PolygonScan. Go to the 1inch contract page, check the available functions, and look for an approval-related option, such as approve or increaseAllowance. This method requires some knowledge of interacting with smart contracts, but it provides an additional way to ensure no permissions remain. In cases where the approval limit was exactly used up during the swap, many tools won’t display an active contract because the allowance is now zero. This means that the 1inch contract no longer has permission to access your XSGD unless you approve it again in the future. If you set a higher approval limit than what was used in the swap, then there could still be an open permission, and revoking it would be necessary. If you want to discuss your situation with others who have encountered similar issues, consider posting in the Polygon Community Forum. Many users share their experiences with token approvals, contract interactions, and wallet security, and you might find additional insights there. After following these steps, if no active approvals appear in any of the tools mentioned, then your transaction likely went through as expected, and no further action is needed.
