Transactions

Transactions, which change the state of the EVM, need to be broadcast to the whole network. Any node can broadcast a request for a transaction to be executed on the EVM; after this happens, a validator will execute the transaction and propagate the resulting state change to the rest of the network.

Transaction Fees on Base

Every Base transaction consists of two costs: an L2 (execution) fee and an L1 (security) fee.

The L2 fee is the cost to execute your transaction on the L2, and the L1 fee is the estimated cost to publish the transaction on the L1. Typically the L1 security fee is higher than the L2 execution fee. L1 gas fields are have the l1_ prefix.
