Bridge Fee
What is a Bridge Fee?
- A Bridge Fee is a fee that a user pays for each bridge transfer.
- A bridge transfer requires 2 transactions: Send transaction on the source chain and Receive transaction on the destination chain. Bridge fee is paid with the Send transaction.
- The bridge fee does not include a gas fee. You will pay for gas yourself.
- The fee is paid in the same token that you transfer.
Fixed Percentage Fee
- Fixed Percent Fee = 0.3% from the transfer amount. For example, if you transfer 100 USDT, you will pay 100 USDT * 0.3% = 0.3 USDT If you transfer 100 SOL you will pay 100 SOL * 0.3% = 0.3 SOL
- This fee is applied for every token and does not depend on the blockchain.
- The bridge fee does not include a gas fee. You will pay for gas yourself.
Dynamic Percentage Fee
How does it work?
- User can decrease the Bridge Fee if he/she has xABR on the blockchain wallet, from which he/she transfers the assets. For example, if the user wants to send USDC from Polygon to Solana, in order to reduce the bridge fee, the user needs to have xABR tokens on the MetaMask address on Polygon, from which he/she sends the assets.

- The bridge fee depends on the user's pool share (amount of xABR). In the beginning, when the staking pool has less liquidity, the user needs to stake less ABR in order to reduce the bridge fee (less xABR is needed). As TVL increases, the user needs to stake more ABR in order to keep the bridge fee on the same level. For example, if TVL is $100,000 and the user stakes $100, the bridge fee will be reduced to 0.04%. However, staking $100 with the TVL of $1,000,000, will reduce it to 0.19%.
- Since the fee is paid with the Send transaction on the source chain, there will be an Allbridge Staking contract on each chain.
- Bridge Fee is calculated right before the Send transaction is triggered.
- The bridge fee does not include a gas fee. You will pay for gas yourself.
- The Minimum Fee will be an equivalent of $0.50, no matter how big the stake is.
- The Minimum Fee will be updated weekly based on the average token exchange rate last week.
What is the formula of fee reduction?
Bridge Fee Calculator will be added soon.
We currently use an exponential system to reduce the fee. Basically, you can stake just a little for the fee to get reduced, but the more you need it to reduce the more you have to stake.
Currently, at 0 stake, the fee is 0.3%, if you have as little as 10 xABR the fee is already at 0.2%, 40 xABR gives you 0.1% and for 0.05% fee you currently need to have around 100 xABR on the staking account.
This all depends on your share of the staking pool, so the larger the pool is, the more you have to stake and vice versa. We’re also refining the numbers a bit based on the performance and users' feedback, so this proportion can change in the future.
Can I pay a $0 fee?
The minimum fee is equivalent to $0.50.
- If you don't have xABR in your wallet and want to send a small number of assets, you are required to pay at least $0.50. For example, you want to send 1 USDT. 0.3% from 1 USDT is $0.03. In this case, the fee will be $0.50 instead of $0.03.
- If you have the amount of xABR that reduces the fee too much, and it will cost less than $0.50, the fee will be $0.50. For example, you want to send 1000 USDT and have as much xABR as enough to reduce the fee to %0.0004. In that case, the fee will be $0.50 insead of $0.40.
