Fee Structure
Base.meme operates on Base with following fee structures setup. Below is a summary of each fee, and its rate.
1. First Buy Fee
How it's charged: Collected as an extra fee from first buyer of the coin. Note: Create on Base.meme is completely free. First buy fee is charged on whoever first bought the created coin.
ETH
0.0015 ETH
USDC
5 USDC
SOL
0.04 SOL
2. Trading Fee (Bonding Curve Phase)
Fee Rate: 2% Note: Fees are charged in the pair token selected at token creation, which may be ETH, USDC or SOL on Base.
Creator
1%
Creator's Referrer
0.2%
Trade Referrer

Base.meme

3. Seeding Fee (Liquidity Pool Creation)
How it's charged: Deducted from the liquidity pool at the time of pool creation. Note: Fees are charged in the pair token selected at token creation, which may be ETH, USDC or SOL on Base.
For Standard mode coins, the seeding fee is charged using the fixed amounts below.
ETH
0.15 ETH
Uniswap
V3 or V4 pool
USDC
500 USDC
Uniswap
V4 pool
SOL
4 SOL
Uniswap
V4 pool
For Advanced mode coins, the seeding fee is 6% of the coin’s funding target (Raised), charged in the selected payment token. Base.meme will show the final amount before you confirm creation.
4. LP Fee (After Graduation)
Fee Rate: Depends on when the coin was created: - For coins created on or after December 5, 2025 (Uniswap V4): 2% of each trade. - For coins created before December 5, 2025 (Uniswap V3): 1% of each trade. LP Token Handling: After liquidity is added, LP tokens are held by the token's bonding curve contract and cannot be withdrawn or transferred, ensuring permanent liquidity lock. Note: Fees are charged in the pair token selected at token creation, which may be ETH, USDC or SOL on Base.

5. Tax Token Fees
Tax Tokens use a separate factory and a different fee structure than the standard V4 deployment. They graduate to Uniswap V2 and support an optional creator-defined transfer/trade tax. See Tax Token for full details.
Platform Trading Fee (Bonding Curve only)
The platform trading fee on Tax Tokens during the bonding-curve phase is 1% (vs 2% on V4 coins). It is split as follows:
Creator
0.5%
Creator's Referrer
0.1%
Trade Referrer
0.1%
Base.meme
0.3%
After graduation, Tax Tokens trade on standard Uniswap V2 pools. Uniswap V2 does not support protocol fee collection on pool swaps, so Base.meme does not collect a platform trading fee on graduated trades — only the standard V2 LP fee (0.3%) applies, which accrues to the bonding curve contract as the LP holder.
Migration Fee
When a Tax Token reaches its funding target and graduates to Uniswap V2, a one-time migration fee equal to 6% of the funding target is charged. For a default 2.5 ETH funding target this is 0.15 ETH. The fee is paid in the selected payment token.
Transfer/Trade Tax (creator-configured)
If the creator enabled the Tax Token feature, an additional tax (0% – creator-defined) is charged on every transfer and trade in the token contract itself. This tax is separate from and on top of the platform fee above.
Collected tax accumulates in the token contract and is distributed across up to four channels when TaxProcessor.dispatch() runs:
Funds Recipient
Direct revenue to the creator's designated wallet, or to a Vault if one is attached.
Holder Dividend
Proportional distribution to all token holders via the Dividend Contract.
Token Burn
Buyback on Uniswap V2, burned to the dead address.
Add to Liquidity
Routes back into the Uniswap V2 LP.
The split (in basis points totaling 100%) is fixed at creation and immutable. When TaxProcessor.dispatch() executes, a 10% processor fee is deducted from the dispatched amount before the channel split is applied.
Vaults
Creators may attach a Vault at creation to automate the Funds Recipient channel: SnowBall (buyback & burn), BurnDividend (burn-to-earn), Gift (X-handle controlled), or Split (multi-recipient). See Vaults for the full strategy comparison.

Note: If the creator configured a Token Tax, an additional creator-defined percentage is charged on every transfer and trade in the token contract. This tax is separate from the platform fees above and is distributed across the four channels (Funds Recipient / Holder Dividend / Token Burn / Add to Liquidity) when TaxProcessor.dispatch() runs. See Tax Token for details.
