Fees

Allbridge Core supports two types of transfer mechanisms, and the fee structure depends on which one is used:

• Pool-based transfers (default for most routes)

• CCTP / OFT transfers (available for specific assets and chains)

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.

Pool-Based Transfers

Pool-based transfers use Allbridge Core liquidity pools and the virtual stable-swap mechanism. The following fees apply:

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.

Liquidity Provider Fee

A total fee of 0.3% is applied by the pools: 0.15% on the sending side and 0.15% on the receiving side.

80% of this fee is distributed to liquidity providers in real time.

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.

Price Impact from Pool Balances (Not a Fee)

Pool-based transfers use stable-swap mechanics. Depending on the current pool balance, the swap result may be:

• positive (user receives slightly more), or

• negative (user receives slightly less)

These differences are not fees!

They reflect the state of the liquidity pool and can be arbitraged back to balanced conditions by external traders.

Important note about this price impact is that it might differ from the one displayed in the UI when the transfer starts. This happens because when the receive transaction is submitted on the target chain the state of the pool may differ from the state when the transfer was initiated.

CCTP / OFT Transfers

For routes using Circle’s CCTP or LayerZero’s OFT, the fee structure differs because the transfer does not interact with Allbridge Core liquidity pools.

The following fees apply:

Relayer Fee

Same as in pool-based transfers.

This fee covers the cost of completing the transaction on the destination chain.

Service Fee

A flat 0.1% fee applied to the transferred amount when using CCTP or OFT routes.

Optional Gas Purchase

Same optional gas top-up mechanism available for pool-based transfers.

There is no LP fee and no pool price impact because liquidity pools are not involved.

Paying Fees: Gas Token or Stablecoin

Both pool-based transfers and CCTP/OFT transfers support flexible fee payment:

• Fees may be paid in the native gas token of the source chain, or

• Deducted from the stablecoins being transferred

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.
