Fees

The bridge is designed to keep fees low and transparent, while covering network costs and preventing spam transact. There are no additional network fees, meaning you only pay the bridge fee—nothing else.

What Fees Are Charged?

Only one fee! The bridge fee is 0.3% of the transferred amount and is applied to every transaction.

Fee Type	Amount	Who Pays?	Purpose
Bridge	0.3% per transfer	Deducted from the user's transaction	Supports bridge operations and prevents spam
Network	❌ None	No gas fees on Constellation BASE gas fees are paid by the bridge	-

Before confirming a transaction, the bridge UI will display the estimated final amount you'll receive.

How the Bridge Fee Works

The 0.3% bridge fee is automatically deducted from the amount you receive. Since no gas fees are required, this is the only cost involved in using the bridge.

1️⃣ You send 1,000 DAG from Constellation to Base. 2️⃣ The 0.3% bridge fee is deducted = 3 DAG on BASE. 3️⃣ You receive 997 DAG in your Base wallet.

B. Example: Bridging from Base to Constellation

Why Is There a Bridge Fee?

The 0.3% bridge fee serves two key purposes:

First, it prevents spam transactions. Since transactions on Constellation are fee-less, adding a small fee discourages abuse, such as repeated micro-transfers that could clog the bridge.

Second, it supports bridge operations. The fee helps maintain and improve the bridge, ensuring long-term sustainability and reliability for users.

Unlike traditional bridges that charge gas fees in addition to service fees, this bridge is designed to be cost-efficient and predictable, with only a single, transparent fee applied to each transfer.
