Account abstraction is one of the features that the Ethereum ecosystem wishes to have for a very long time. ERC-4337 is one of the most developed and possible standards to be adopted, but the infrastructure needs to be battle-tested before integrating AA natively in Ethereum and other L2s. Silius helps build the necessary infrastructure, helps with client diversity, and is one of the first three bundlers to test public P2P mempools (which help with censorship resistance and decentralization of AA's order flows).
