| ## Simple Summary | ||||||
| Starts the `COINBASE` address warm | ||||||
|
|
||||||
| ## Abstract | ||||||
| The `COINBASE` address shall be warm at the start of transaction execution, in accordance with the actual cost of reading that account. | ||||||
|
|
||||||
| ## Motivation | ||||||
| Direct `COINBASE` payments are becoming increasingly popular because they allow conditional payments, which provide benefits such as implicit cancellation of transactions that would revert. | ||||||
| But accessing `COINBASE` is overpriced; the address is initially cold under the access list framework introduced in [EIP-2929](https://eips.ethereum.org/EIPS/eip-2929). | ||||||

| This gas cost mismatch can incentivize alternative payments besides ETH, such as ERC20, but ETH should be the primary means of paying for transactions on Ethereum. | ||||||
|
|
||||||
| ## Specification | ||||||
| At the start of transaction execution, `accessed_addresses` shall be initialized to also include the address returned by `COINBASE` (`0x41`). | ||||||
|
|
||||||
| ## Rationale | ||||||
| The addresses currently initialized warm are the addresses that should already be loaded at the start of transaction validation. | ||||||
| The `ORIGIN` address is always loaded to check its balance against the gas limit and the gas price. | ||||||
| The `tx.to` address is always loaded to begin execution. | ||||||
| The `COINBASE` address should also be always be loaded because they receive the block reward as well as the transaction fees. | ||||||

Hi, could you explain what is
Direct COINBASE payments? thanks in advance.BTW, the EIP still encourage users to paying for transactions on Ethereum?
