A decentralized "dead man's switch" for crypto inheritance on Solana, ensuring your digital assets reach your loved ones. Or just use it as a simple time-lock for your solana based asset to surprise someone on their birthday maybe.
What if Satoshi Nakamoto wanted to pass on his 1.1 million BTC but disappeared or passed away? In the crypto world, there's no built-in inheritance system. Unlike traditional banking, crypto assets can be permanently lost if the owner passes away without sharing their private keys or recovery phrases. I wished to make something that would allow people to easily set up an inheritance system for their crypto assets, without the need of a centralized service.
Eternal Key provides an automated, trustless solution for crypto inheritance:
- Set up a "dead man's switch" that activates after a period of inactivity
- Designate beneficiaries who can claim assets after the deadline
- Regular "check-ins" to prove you're still active
- Completely decentralized and non-custodial
- Built on Solana for speed and low costs
- The SOL locked into the escrow can be recovered once the account is closed upon withdrawal from the beneficiary.
- Activity Monitoring: Automated tracking of wallet activity
- Secure Transfers: Trustless transfer to beneficiaries after inactivity threshold
- Flexible Check-ins: Extend your deadline with simple check-in transactions
- Multi-Asset Support: Works with SOL and other Solana tokens
- Non-custodial: You maintain full control of your assets
- Low Cost: Minimal fees for setup and maintenance
The core functionality is implemented in Rust using the Anchor framework:
initialize: Create new dead man's switchdeposit: Add funds to escrowcheckin: Reset/extend the deadlineclaim: Beneficiary claims funds after deadlinecancel: Owner cancels switch and reclaims funds
