Safe makes it easy for anyone to make and use smart accounts (aka Account Abstraction) on the blockchain.


Safe will be giving $10,000 for the best hacks using Safe {Core}. To be eligible, developers must use at least one of the Safe {Core} Account Abstraction SDK kits listed below.

๐Ÿงฐ Protocol Kit

The Protocol Kit uses the Safe Core SDK to interact with Safe contracts using a Javascript interface. This SDK can be used to create new Safe accounts, update the configuration of existing Safes, and propose and execute transactions.

โœ… Auth Kit

The Auth kit creates an Ethereum address and authenticates a blockchain account using an email address, social media account, or traditional crypto wallets like Metamask.

๐Ÿ’ณ Onramp Kit

The Onramp kit allows users to buy cryptocurrencies using a credit card and other payment options.

๐Ÿƒ๐Ÿปโ€โ™€๏ธ Relay Kit

The Relay Kit allows users to pay transaction fees (gas fees) using the native blockchain token or ERC-20 tokens. This allows you to pay gas fees using any ERC-20 token in your Safe, even if you don't have ETH.

Other Account Abstraction bounties
