Hi Product Hunters! John from Stackup here. I’m a rocket engineer turned blockchain entrepreneur (yes, I know, my parents are disappointed too). Last time I did a launch here was for a crypto wallet that Hazim and I developed. After a bunch of iteration we realized that the infrastructure for our wallet didn't exist, so we worked with the Ethereum Foundation to implement a new standard for smart accounts on blockchains called ERC-4337. Building user-friendly blockchain apps is really difficult. There are all kinds of restrictions for what blockchains can do, and you often have to place a ton of burden on the user to manage keys, sign transactions, pay blockchain gas fees, and so on. With Stackup, you’ll be able to build custom web3 transactions so that your users don’t need to be blockchain experts just to use your app. You can sponsor gas fees for your users, create recoverable smart contract wallets for them, and even bundle transactions together so any complex set of actions in web3 can be one click. What sets Stackup apart? Stackup is an open-source platform built on ERC-4337, a new “account abstraction” technology that basically handles the hard parts of blockchains for users. It’s developed by the Ethereum Foundation and works on most major blockchain platforms, like Ethereum, Polygon, BNB Chain, and more. Use it for free! It’s free to give Stackup a try! I’ve recorded a few video examples on our docs page and YouTube channel, but please feel free to reach out to us and request more! Best, John

Love it!
