Aurora runs on top of NEAR, meaning that the underlying NEAR gas is the real measure of computational work. However, for compatibility with Ethereum we want our users to be able to pay for transactions with ether (ETH). To enable this, the Aurora infrastructure includes relayers which encapsulate ordinary EVM transactions into NEAR transactions, submit them on-chain, and return the transaction result.

Transaction cost ~$0.02 (this value is not calculated automatically, just based on our observations).
