Programmable accounts on Ethereum aren’t a thought experiment anymore. They’re here, they work, and they’re changing how wallets, dapps, and even banks ship on-chain experiences. If you build anything that touches keys, gas, or user flows, the ground under you just moved.
This piece lays out what actually changes with ERC-4337 and EIP-7702, where teams get burned, what to refactor first, and how to roll out safely. I’ll keep it practical. Clear steps. Real tradeoffs. No mystery.
Builders need to treat accounts as programmable endpoints, not dumb key pairs. That means shifting auth to passkeys and session keys, moving fee logic to paymasters, validating on-chain with explicit policies, and hardening everything against new phishing and approval traps. EIP-7702 lets EOAs borrow smart logic for smoother UX, while ERC-4337 gives full smart-account rails. You’ll likely support both.
Retool auth for WebAuthn, session keys, spending limits, and recovery.
