🪙 Fee
Aptoswap platform takes trading fees from every swap. When trading, you pay a percentage of the trade value as a fee. These fees vary depending on the route the AMM uses and the pool configuration.
The collected fee will further be split into 4 different types of fee with different usage: liquidity provider base fee, liquidity provider incentive fee, connect fee, and treasury.
Liquidity provider base fee: The type of fee will be directly rewarded to liquidity providers and will stay unchanged when the pool is created.
Liquidity provider incentive fee: This type of fee is an extra boost reward to liquidity providers to encourage them to provide liquidity when the pool is created. However, unlike the base reward fee that will remain unchanged, the fee will progressively decrease to zero from the pool creation time.
Connect fee: This type of fee will be used to automatically buy-back platform tokens and reward those platform tokens to the liquidity providers.
Treasury: This type of fee will be taken by the platform for Aptoswap protocol development, community management, and conditional platform token buyback.

The suffix
incentiveindicates the pool is in "incentive mode". The "incentive mode" is set for those newly created pools to encourage liquidity providers for depositing. Inincentive mode, all the remaining Aptoswap treasury fee will be rewarded to liquidity providers, which means the liquidity providers could get all the fee rewards from Aptoswap. Theincentivefee will progressively decrease to zero and convert to Aptoswap treasury and connect fee through time.The suffix
connectmeans the pool is connected to another platform token pool and it will use the connect fee to automatically buy back platform token from the target pool and automatically rewards to liquidity providers when they withdraw their liquidities. See Connect Pool
🗄️ Withdraw Fee
To avoid attackers disturbing the pools by frequently depositing and withdrawing liquidity from the pool. We take a small amount of withdraw fee from harvesting tokens from pools. Currently, the withdraw fee is fixed at 0.05% for all the pools.
For example, a liquidity provider tries to withdraw 2 BTC and 40000 USDT token from BTC/USDT. 0.1 BTC and 20 USDT will be taken and deposited to the Aptoswap treasury.
