ONE NETWORK AT A TIME
Gas tokens and fees, network by network
Where your tokens live. Each network has its own fee asset, its own confirmation behaviour and its own set of token versions, and these pages summarise what changes between them.
Ethereum
The settlement layer most bridged tokens originate from. Fees are paid in ETH and vary with demand.
Network notesBase
An OP Stack layer 2 with ETH gas and a two-part fee: execution on Base plus the cost of posting data to Ethereum.
Network notesArbitrum One
A layer 2 with ETH gas, a gas estimate that may already include the parent-chain cost, and two circulating versions of USDC.
Network notesOP Mainnet
An OP Stack layer 2 whose fee is documented as three separate components, all paid in ETH.
Network notesPolygon PoS
An EVM network with its own gas token, POL, which replaced MATIC on Polygon PoS in September 2024.
Network notesTRON
A non-EVM network with its own address format and a resource model instead of gas pricing.
Network notesSolana
A non-EVM network with a fixed per-signature base fee, optional priority fees, and a storage deposit for new accounts.
Network notesBNB Smart Chain
An EVM network with chain ID 56 whose fees are paid in BNB rather than ETH.
Network notesNetwork notes, not endorsements.
Naming a network is not a recommendation to use it, and a documented fee asset does not tell you what a specific platform supports today. Check the deposit instructions of the account you are sending to.
