Uniswap

@uniswap smart wallet is live!!

This is a huge unlock for wallet UX and one of the most sneakily complex projects I’ve ever worked on.

Quick 🧵 on a few of the design principles behind our 7702 wallet implementation:

The largest onchain marketplace. Buy and sell crypto on Ethereum and 13+ other chains.

1️⃣ Invest in simplicity

7702 gets messy quick. Delegation requires gas. Delegation status can vary across networks. Wallets may only support a subset of smart wallet features or be totally incompatible.

I went deep on edge cases and dependencies to untangle complexity so 99% of Uniswap users will tap one button then never need to think about smart wallets again.

2️⃣ Embrace new norms

Gas abstraction, batched txns, automated trades... These are the building blocks for any modern wallet. What’s cutting-edge today will be table stakes tomorrow.

Smart wallet will be auto-enabled for all new wallets; 1-click activation for existing users. By default, everyone gets the best UX Ethereum has to offer.

3️⃣ It needs to Just Work™

Early days for 7702 may be bumpy as dapps + wallets coalesce around standards. Transparency, control, and graceful fallbacks for users are key.

We fully refactored our swap architecture so every user has a seamless trading experience regardless of delegation status. Swaps feel fast, effortless, and dependable no matter what's going on behind the scenes.
