Inspiration

Most times when a person dies or misplaces his private key, his cryptocurrencies are lost forever on the Blockchain.

What it does

Heritage allows you to transfer your assets to your heir in a decentralized manner.

• User register and provide their next of kin details (address)
• User also sets a checkIn interval(how frequent they want to check in)
• User selects tokens to be inherited (and allow the Heritage smart contract to spend their token)
• If User does not check in after an amount of time > checkInterval has passed, the tokens are transferred to the next of kin

How we built it

It was built using, react, ethersjs and solidity. We also used Chainlink Automation to handle automatic execution of the transactions.

Challenges we ran into

• Creating an Automation compactible contract
• Handling edge cases in smart contract

Accomplishments that we're proud of

• We learnt how to create an Automation compatible contract in a short time frame
• We also got a deeper understanding of the ERC20 token standard

What we learned

• How to use Chainlink Automation

What's next for Heritage

• Allow multiple heirs
• Allow inheritance of NFTs
