Service Fees

This page explains which fees AntiDrain can show and when they appear.

Gas Is Not a Service Fee

Network gas is not an AntiDrain service fee. Gas is paid to the network for running the transaction. A service fee, if present, is shown separately before sending.

AntiDrain has two main fee types.

1. Token Rescue Fee

This is a fee in the token being rescued.

It usually applies to a fee-bearing token rescue, where the site or contract takes a percentage of the amount actually rescued.

To Whom	Without Affiliate	With Active Affiliate
User / Recipient	80%	80%
Protocol	20%	15%
Affiliate	—	5%

Examples:

• 100 USDT is rescued: recipient receives 80 USDT, total fee is 20 USDT
• With an active affiliate link, affiliate receives 5 USDT and protocol receives 15 USDT
• 1,000 TOKEN is rescued: recipient receives 800 TOKEN, total token fee is 200 TOKEN

When Token Rescue Fee Appears

Token rescue fee can appear in these cases:

• ERC-20 token rescue in Custom TX Builder when a fee-bearing transfer is selected
• ERC-20 transfer-all, where the fee is calculated from the real balance at execution time
• Permit Rescue when the selected mode uses balance-at-execution
• DeBank/Bundler token transfer when that route uses fee split
• DeBank native transfer-all when that route supports this split

Token rescue fee usually does not apply when:

• Remove Delegation only clears EIP-7702 delegation
• Permit Rescue sends an exact amount without a fee-bearing balance-at-execution mode
• The action does not move tokens or native balance through a fee split

2. Native Service Fee

This is a separate fee in the network's native coin: ETH, BNB, POL, AVAX, and so on.

The site calculates it in fee units. One fee unit is $5. Then the site converts that amount into the native coin using the current price.

Examples:

• 1 fee unit = $5
• 2 fee units = $10
• 3 fee units = $15

If an affiliate link is active, native service fee is split this way:

• Protocol receives 75%
• Affiliate receives 25%

For example, if native service fee is $10, the affiliate reward is $2.50 in the native coin.

When Native Service Fee Appears

Native service fee can appear when the service prepares a more complex action instead of a normal token fee.

In Custom TX Builder:

• Raw custom call without ERC-20/NFT transfer: 1 fee unit for each raw call
• ERC-721 transfer: 1 fee unit for each NFT transfer
• ERC-1155 transfer: 1 fee unit for each NFT transfer
• ERC-20 transfer by itself usually uses token fee, not native service fee
• If the batch is mixed and contains token/NFT transfer, raw custom calls in the same batch may not add a separate native service fee

In DeBank Withdraw:

• Selected pool action: 1 fee unit for each selected pool
• Raw call: 1 fee unit for each raw call
• Regular token transfers usually do not add native service fee

When Native Service Fee Is Zero

Native service fee should be 0 when the selected flow does not require it.

Usually this means:

• Remove Delegation
• Permit Rescue without native service fee
• Normal fee-bearing token rescue where the fee is already taken in the token
• DeBank/Bundler token transfer without raw/pool/native service-fee action

How the Site Calculates the Native Amount

First, the site counts fee units. Then it multiplies them by $5.

After that, the site tries to get the native coin price from price providers and convert USD into ETH/BNB/POL/another native coin.

If the price is unavailable, the network is custom, or the coin symbol is unsupported, the site may use a fallback estimate. In that case the amount can be based on estimated gas cost, not on the exact $5 per unit price.

If the transaction plan already contains a locked service fee, Fund Donor and Send should use that locked amount.

What to Check Before Sending

Check All Fees Before Sending

If a fee looks unexpected, do not send immediately. Go back to Build or Simulation and check the selected action and route.

Before sending, check:

• Selected network
• Gas reserve
• Native value, if the transaction sends native coin
• Token fee, if the rescue takes a percentage in the token
• Native service fee, if present
• Total amount that must be funded to the donor wallet
• Affiliate split, if an affiliate link is active
