+[The EIP 1559 parameters](./differences.md#eip-1559) have different values in OP Mainnet (and most other OP Stack chain) than those on L1 Ethereum.
 As a result, in every block the base fee can be between 98% and 110% of the previous value. 
 As blocks are produced every two seconds, the base fee can be between 54% and 1,745% of the value a minute earlier.
 If it takes the user fourteen seconds to approve the transaction in the wallet, the base fee can almost double in that time.

+This guide is intended for wallet developers who want to give their users the ability to send transactions on OP Mainnet (most other OP Stack chains behave similarly).
 OP Mainnet generally behaves like any other EVM-based chain with the exception of minor discrepancies related to [transaction fees](#transaction-fees).
 These fee discrepancies are an inherent result of the fact that OP Mainnet is a Layer 2 blockchain network that must publish transaction data to Ethereum.
