1/ Early on, the Base team made smart contract wallet (AKA smart account) adoption one of their top priorities. Last week, Base had more ERC-4337 smart account activity than any other chain. Let's take a look at the stats 👇

Smart account (AKA smart contract wallet) adoption is one of the top priorities of the @Base team. Last month, Base ranked second for ERC-4337 smart account usage. [Polygon was #1] 81,000+ UserOps were made on Base in March. [UserOps are transactions made by ERC-4337 accounts]

🔍 Smart Accounts deep dive Come ride the onchain data as we investigate: →What are smart accounts being used for? →How much value is transferred? →Are users being retained? @blockomotive @0xKofi @0xBundleBear @p_petertherock @danielpartidag Dive in: https://t.co/kfrPN2amTM

ERC-4337 Paymasters allow - Apps to sponsor gas fees for their users - Users to pay gas with ERC20s Ive updated BundleBear to track which 4337 user operations are sponsored vs paid-with-ERC20s In February, ~97% of UserOps that used a paymaster were sponsored The dominant use

Smart accounts are taking off! However, we require a standard that allows for continued innovation without compromising smart account interoperability. The ERC-7579 reference implementation is out! Enabling module developers to build once and distribute everywhere! 🧵

New Feature: " Bundle Frontrunning" Bundlebear has a new chart tracking bundle transactions that reverted because they were frontran

New Feature: "UserOps by Category" Bundlebear has a new chart segmenting UserOps by category. You can see if the UserOps were interacting with NFTs, transferring ERC20s, using a social app .etc

I added Avalanche data to BundleBear, my ERC4337 dashboard 🔺✨ Here's a quick rundown of ERC4337 activity on Avalanche

Last week, 54,000 smart accounts minted @AnichessGame NFTs on Polygon ♟️✨ This spiked the number of weekly active smart accounts to levels we haven't seen since November 2023

Introducing "BundleBear Year In Review 🐻✨" A data-driven summary of the major trends that shaped ERC-4337 adoption this year. - User Behaviour - Popular apps - Bundler and Paymaster Performance And more!

Note: This is for Paymaster activity on Polygon, Arbitrum, Optimism, Base and Ethereum. New chains coming in new year. This includes all paymaster spending .ie both where the paymaster was compensated in ERC20s and where the app subsidised the fees.

We just crossed $1,000,000 of ERC-4337 Paymaster spending on UserOp fees Congrats and Merry Christmas all 🎅✨

How much does it cost to use an ERC4337 account? Smart contract wallets, also known as smart accounts, address many of the shortcomings of EOA wallets. They have customizable logic and enable features such as gas sponsorship, gas payments with ERC-20 tokens, multisig schemes,

There's been a lot of debate about whether or not ERC4337 accounts are too expensive. I analyzed onchain data to find out how much ERC4337 users have been spending on common actions ( eg. ERC20 transfers) and compared their costs to Safe users. Here are the results 👇

Insight In November, 16% of Bundle transactions contained multiple UserOps. This marks a significant improvement compared to earlier in the year when the monthly percentage share of multi-UserOp bundles was often below 1%.

New Feature: "Operator Profiles 🔍✨" On the Bundler and Paymaster pages, you can click on the name of an operator to pull up their profile page and see their performance stats.

Happy to announce that @Biconomy has become a BundleBear sponsor 🥳🥳🥳 Big thanks to the team at Biconomy for supporting open-source smart account data!
