Contract source
Before you start
A compatible taxable token and the relevant tax permission. Inspect its permanent tax ceiling and supported transfer, buy and sell rates.
How to use this tool
- Inspect the current rates and immutable maximum.
- Enter only the rates this token exposes; review registered pools for buy/sell classification.
- Review the new rates and approve the update.
What changes
Supported future transfers use the configured rates within the contract’s permanent ceiling. A tax change does not create liquidity or register a pool.
A 1% rate is 100 basis points. A permanent 2% ceiling cannot be raised by entering a larger rate here.
Common problem
Why is a buy or sell using the wrong rate?
Check the registered trading pools, exemptions and token capabilities. Separate buy and sell rates require the matching contract configuration.
Network and protocol costs are separate. Your transaction review shows the current amounts.
