Fee Tier
The percentage of each trade charged as a fee in a liquidity pool; common tiers are 0.01%, 0.05%, 0.30%, and 1.00%.
Fee Tier — A fee tier is the percentage charged on each swap in a DEX liquidity pool, set at the time of pool creation. Different fee tiers serve different types of token pairs: lower fees for stable pairs with minimal price divergence, and higher fees for volatile pairs where liquidity providers need more compensation for impermanent loss risk.
What Is a Fee Tier?
A fee tier is the fixed swap fee rate assigned to a liquidity pool. On Uniswap V3, pools can be created with fee tiers of 0.01%, 0.05%, 0.3%, or 1%. Each token pair can have multiple pools at different fee tiers, and routers direct trades to the pool offering the best execution.
The fee tier determines both the cost for traders and the revenue for liquidity providers. Higher fees mean more LP income per trade but also higher costs for traders, potentially driving volume to competing pools or DEXs.
How Fee Tiers Work
When a pool is created, the deployer selects a fee tier. All swaps in that pool charge the specified percentage, which is deducted from the input token and added to the pool reserves. For a 0.3% fee tier, a $1,000 swap costs $3 in fees distributed to LPs.
Fee tier selection also determines tick spacing, which affects LP position precision. The 0.01% tier has the finest tick spacing (1), ideal for stablecoin pairs. The 1% tier has the widest spacing (200), suited for highly volatile or exotic pairs.
Why Fee Tiers Matter
Choosing the right fee tier is critical for both LPs and traders. For stablecoin pairs like USDC/USDT, the 0.01% tier attracts the most volume because these tokens rarely diverge in price and impermanent loss is negligible. For volatile pairs like ETH/memecoin, the 1% tier compensates LPs for higher IL risk.
Most volume concentrates in a single fee tier per pair, typically the one with the deepest liquidity. Traders benefit from comparing fee tiers, as the cheapest tier with adequate liquidity gives the best execution.

Common questions about Fee Tier in cryptocurrency and DeFi.
For stablecoin pairs, use 0.01% or 0.05%. For major pairs like ETH/USDC, 0.05% or 0.3% are most common. For volatile memecoins, 0.3% or 1% compensates for higher impermanent loss. Check which tier has the most existing liquidity for your pair.
No. A pool fee tier is fixed at creation. However, anyone can create a new pool for the same token pair at a different fee tier. If a different fee tier becomes more efficient, liquidity and volume will naturally migrate to it.
No. Uniswap V3 offers 0.01%, 0.05%, 0.3%, and 1%. PancakeSwap V3 offers similar tiers. Curve pools typically charge 0.04%. Raydium concentrated pools use 0.01% to 1%. Some DEXs allow custom fee tiers through governance proposals.
