Rate Limiter
Available on DBC.
On DBC, we allow partners to configure another mode for base fee, called Rate Limiter .
When rate limiter mode is enabled, the fee slope will increase if a user buys with a higher amount.
For example, if a user swaps 100 SOL, then the first SOL will be charged as 1%, the next SOL will be charged as 5%... until it fulfils full input amount.
Notes:
The rate limiter mode is only available if collect fee mode is in quote token only, and when the user buys the token (not sell).
Rate limiter doesn't allow user to send multiple swap instructions (or CPI) to the same pool in 1 transaction.
In the field
base_fee_modein base fee state, partners have to choose between Fee Scheduler or Rate Limiter.
