Fees

There are two types of fees associated with using Across:
1.Destination gas fees
2.Bridge fees
Destination gas fees
In order for Across to deliver the tokens to the user on the destination chain, a transaction needs to be submitted on behalf of the user on the destination chain.
The destination gas fee encompasses the gas costs associated with this transaction.
Bridge fees
Bridge fees are themselves broken into two components:
1.LP fee: Fee paid to liquidity providers for providing passive liquidity that is utilized by the system to refund relayers
2.Relayer fee: Fee paid to incentivize relayers to relay your bridge transaction quickly
LP Fee
The LP fee depends on the transaction size and how much of the current liquidity is being utilized. 
These fees are typically on the order of 0.06% to 0.12% of the transaction which means that on a 1 ETH transfer you would pay an LP fee of 0.0006 to 0.0012 ETH.
Relayer Fee
The relayer fee is a fee chosen by the user to incentivize relayers to relay their transaction. A user should consider three components when choosing this fee:
1.Gas: How much will it cost the relayer to perform the relay?
2.Capital + Risk: What is the opportunity cost of the relayers capital?
In practice, most users should use the value recommended by the front-end.
