✅BSC Customized Pre-Authorization
BSC Pre-Approval | Token/NFT Allowance | Faster Execution
Pre-set token or NFT allowances for specific addresses to enable faster on-chain execution and improve interaction efficiency.
Note: This tutorial uses BSC (BNB Chain) for demonstration purposes.
SlerfTools is fully multi-chain compatible. Whether you are operating on Base, ETH, X Layer, Plasma, or Monad, the workflow remains identical.
Simply ensure your Web3 wallet (e.g., OKX, MetaMask) is switched to your target network.

Language settings: once on the page, the top right corner supports switching languages.
Import private key
Enter the wallet private key directly. SlerfTools only computes locally and uses it to sign transactions; it will never collect or upload your private key information.
Security Reminder
SlerfTools never collects or stores private keys; all signatures are completed locally.
In the face of increasingly complex on-chain security threats, we recommend you:
Regularly use【Token Batch Collection】feature to consolidate tokens scattered across multiple accounts into a single main account.
Regularly use【Wallet Asset Migration】feature to move assets to a brand-new wallet with an uncompromised private key to mitigate risks.
Security is no small matter; losing assets leads to lifelong regret.
Select token or NFT
Token: one-click to select mainstream tokens, or paste the token contract address and confirm.
NFT: enter the NFT collection (contract) address and confirm.
Choose approval contract address
Token: select or add custom contract addresses that require approval; approve only trusted contracts to avoid asset risks.
The page lists common contracts for quick selection and approval, and you can view the selected project’s approval status for these common contracts.
Adding custom contracts is supported, and custom contract information is stored locally.
NFT: select or add the contracts that require approval, then confirm.
The page lists common NFT contracts for quick selection and approval, and you can view the selected project’s approval status for these common contracts.
Adding custom NFT contracts is supported, and custom contract information is stored locally.
Set approval amount
Token: custom input the approval amount, or choose "Unlimited amount". (Unlimited approvals carry higher risk; please use cautiously.)
NFT: NFTs do not require setting an amount; just Authorize.
Wallet confirm approval
Click 【Approve】 and sign and submit in the wallet (a small amount of gas is required).
If executed by importing a private key, the system will automatically initiate the transaction and complete on-chain confirmation.
This feature is completely free. We recommend checking your wallet’s token approvals regularly and promptly revoking approvals for any untrusted contracts to keep your wallet secure.
