Cross-chain relayer gas fee

The Axelar network charges a relayer gas fee for all cross-chain token transfers in order to pay for network-level transaction ("gas") fees across chains. The relayer gas fee amount depends only on:

  • the asset
  • the source chain
  • the destination chain
💡

The relayer gas fee does NOT take a percentage from the transfer amount.

Example: a transfer of X USDC tokens from Ethereum to Osmosis will have a fee of 40.5 USDC (= 40 USDC for Ethereum + 0.5 USDC for Osmosis), and so the recipient will get X - 40.5 USDC tokens on Osmosis.

The current gas relayer fee is also available via node query:

axelard q nexus transfer-fee [source chain] [destination chain] [amount]

Example: transfer USDC from Ethereum to Osmosis. (The amount here is arbitrary---gas relayer fees do not depend on the amount. 1 USDC = 10^6 uusdc).

axelard q nexus transfer-fee terra osmosis 1000000000uusdc

The per-chain gas relayer fee info can be queried via

axelard q nexus fee avalanche uusdc

If the total amount of a token sent to a deposit address A is NOT greater than the gas relayer fee then those deposits will wait in the queue until a future deposit to A brings the total above the fee.

The gas relayer fee does not include any transaction fee assessed by the source chain for transferring tokens into a deposit address. These fees are usually denominated in native tokens on that chain (for e.g. AVAX on Avalanche, ETH on Ethereum).
