Key features 🎲
Account abstraction 👤
The frontend of this project is built using Nextjs. Under the hood, this project builds on top of the @account-abstraction-sdk by Eth-infinitism to enable first class citizen contract accounts. We wrote smart contracts inheriting from SimpleAccount and SimpleAccountFactory with additional features - recurring payment and social recovery.
Recurring payment 🔂
For the former, when a user sets up a recurring payment order, we write it to the account smart contract (setUpRecurringPayment) as well as creating a task in Gelato Network), create a task in Gelato Network and store the payment details in Polybase. It will then call the specified function to execute the transaction (makeRecurringPayment) every interval defined by the user.
Social recovery 🤝
As for social recovery, we are using Optimism’s Attestation Station. First, the user specifies 3 addresses that can attest for them in the event of lost access to the account. In order to recover the funds within it, the 3 addresses need to send an attestation to the smart contract. Then, a function can be called in the account contract to move the funds to another
As for social recovery, we have integrated with Optimism’s Attestation Station to achieve this feature. To set up social recovery, the account owner would specify 3 addresses as their social recovery addresses. In the event of losing the key to the ReccuriPay account, the account owner would create a new wallet and ask the owners of the registered social recovery accounts to make attestations that the account is lost, and specify the new wallet address. When all 3 addresses have attested. A function can be called in the account contract to move any tokens or ETH to the attested new wallet address. Optimism’s Attestation Station is easy to integrate and provides a simple and secure mechanism to build our social recovery feature.
