lightclient	cdb66c89d6	core/txpool/legacypool: add support for SetCode transactions (#31073) ... The new SetCode transaction type introduces some additional complexity when handling the transaction pool. This complexity stems from two new account behaviors: 1. The balance and nonce of an account can change during regular transaction execution *when they have a deployed delegation*. 2. The nonce and code of an account can change without any EVM execution at all. This is the "set code" mechanism introduced by EIP-7702. The first issue has already been considered extensively during the design of ERC-4337, and we're relatively confident in the solution of simply limiting the number of in-flight pending transactions an account can have to one. This puts a reasonable bound on transaction cancellation. Normally to cancel, you would need to spend 21,000 gas. Now it's possible to cancel for around the cost of warming the account and sending value (`2,600+9,000=11,600`). So 50% cheaper. The second issue is more novel and needs further consideration. Since authorizations are not bound to a specific transaction, we cannot drop transactions with conflicting authorizations. Otherwise, it might be possible to cherry-pick authorizations from txs and front run them with different txs at much lower fee amounts, effectively DoSing the authority. Fortunately, conflicting authorizations do not affect the underlying validity of the transaction so we can just accept both. --------- Co-authored-by: Marius van der Wijden <m.vanderwijden@live.de> Co-authored-by: Felix Lange <fjl@twurst.com>	2 weeks ago
