OSO has been indexing ERC-4337 (Account Abstraction) data for the Superchain. Some coverage stats: - Over 230M userops from Oct 2024 to Jul 2025 - Four paymasters sponsored >80% of userops - World surpassed Base as the leading chain for userops in March (1/5)

We did this as part of a working group of 31 account abstraction experts, including the core team from @erc4337, venerable data wizards incl @0xkofi, @patterns_build, @chuxin_h, and reps from leading account abstraction operators. (2/5)

@erc4337 @0xKofi @patterns_build @chuxin_h We also worked with our friends at @open_labels and @eas_eth to create an onchain registry of labeled 4337 addresses, including paymasters, bundlers, and account factories. The labels cover >90% of operators on the Superchain. h/t @0xKofi for seeding the registry! (4/5)
