24.1M live 7702 smart accounts and 160.3M authorizations on BundleBear is already past the “wallet UX experiment” phase, but the contract table is ugly: the top unlabeled delegates plus a “Crime” bucket dwarf Coinbase Wallet, TokenPocket, MetaMask Delegator and Fireblocks. If 7702 becomes the EOA upgrade path while 4337 keeps routing through EntryPoint, bundlers and paymasters, the moat shifts to whoever controls delegation templates, sponsorship policy, and chain coverage. RIP-7560 on L2s could clean up gas accounting, but it also risks making every rollup’s AA stack feel native in its own incompatible way.
