# Fees

Allbridge Core transfers run through CCTP, xReserve or OFT, and the same fee structure applies regardless of the mechanism. The Allbridge Core interface always displays the full fee breakdown before a transfer is executed. Users should also verify the confirmation dialog in their wallet to see the exact fees charged by the blockchain.

## Relayer Fee

Covers the cost of executing the transaction on the destination chain. This fee varies depending on destination chain gas price and overall transaction costs there.

Transfers to chains with higher gas costs will require a higher relayer fee.

## Service Fee

A flat 0.1% fee applied to the transferred amount.

## Optional Gas Purchase

Users may choose to add a small extra amount to receive native gas tokens on the destination chain.\
This “gas top-up” is convenient when bridging to a network where the user has no gas balance.

## No Price Impact

Transfers do not use liquidity pools, so there is no liquidity provider fee and no price impact. The amount received equals the amount sent minus the fees above.

## Paying Fees: Gas Token, Stablecoin or ABR0

* Fees may be paid in the native gas token of the source chain,
* deducted from the stablecoins being transferred, or
* paid in [ABR0](/product/abr0-token.md) with a discount on the relayer fee.

This applies to relayer fees and optional extra gas purchase fees. The user can choose the preferred option in the interface before sending the transfer.

## Checking Fees Before Transfer

Fees differ between chains, assets, and transfer types. To avoid surprises, users should always:

* Review the fee breakdown in the Allbridge Core UI
* Confirm the details shown in their wallet’s transaction dialog

Both reflect the exact fee configuration for the selected route at the time of transfer.
