Why can’t I create a UniV3 LP?

Fee-on-transfer tokens, including NXD, are not supported on UniV3 due to specific integration issues outlined in their documentation, which can be found here:

https://docs.uniswap.org/concepts/protocol/integration-issues. Consequently, it is not feasible to establish a UniV3 liquidity pool with NXD; instead, UniV2 remains the available platform for creating LPs with such tokens.
