FAQ(s)

Q1: Are rebasing token supported?

Yes, rebasing tokens are supported on PancakeSwap V2.

There are two types of rebases:

  1. Positive Rebase: Token supply increases.
  2. Negative Rebase: Token supply decreases.

PancakeSwap V2 pools maintain an internal reserve state, so after each rebase, it's important to manually update the pool's reserves.

Syncing After a Rebase

  • After a rebase, you should call:
pool.sync();

This ensures the pool’s internal reserves match the actual token balances.

  • For a positive rebase, if the protocol prefers to retain the excess tokens, you can call:
pool.skim(address to);

This transfers the excess tokens (beyond what the reserves account for) to a specified address instead of updating the reserves.

Q2: Are fee-on-transfer token supported?

Yes, they are.

When interacting with fee-on-transfer tokens, ensure you use the router functions that support them.

These functions end with SupportingFeeOnTransferTokens, such as:

Q3: Are LP or Protocol Fees Considered Part of V2 Pool Liquidity?

Yes, both LP and protocol fees are considered part of the PancakeSwap V2 pool liquidity.

  • LP fees are automatically compounded into the LP position.
  • Protocol fees are minted to the protocol as LP tokens, maintaining them within the pool’s liquidity.
