Token Integration Issues
Last modified:
Fee-on-transfer and rebasing tokens are not compatible with v3.
Fee-on-transfer tokens
These tokens deduct a fee on every transfer call, so the amount received by the pool is less than the amount sent. The router contracts do not account for this discrepancy and will revert. No router supporting fee-on-transfer tokens is planned; token creators who require compatibility should deploy a wrapper contract or a custom router.
Rebasing tokens
Rebasing tokens adjust every holder's balance periodically. Pool creation and swaps will succeed, but liquidity providers bear the full loss of any negative rebase while their position is active — with no mechanism to recover it.
