In today’s digital world, managing what happens to your online assets after death or long inactivity is a real concern.
Trustchain provides an on-chain solution that automates this process using smart contracts.
The contract allows an owner to:
Register heirs and assign each a percentage of their estate.
Periodically send a “heartbeat” to signal activity.
Automatically release the assets to heirs if the owner remains inactive for a defined period.
This eliminates reliance on centralized entities and ensures transparency, immutability, and trustless execution.

The mission of Trustchain is to ensure that no digital asset is ever lost due to forgotten keys, unexpected death, or prolonged inactivity.
We aim to provide a fully trustless, secure, and decentralized way for individuals to preserve their digital wealth and pass it on to their loved ones without intermediaries, legal hurdles, or centralized risks.
Trustchain empowers users to create an autonomous, self-executing digital legacy that guarantees asset continuity, protects long-term value, and preserves ownership beyond the owner’s lifetime — all through transparent and immutable smart contracts.
People today own a lot of digital assets — crypto, NFTs, stablecoins, domain names, tokenized property, wallets — BUT…
i) If they die unexpectedly
ii) Or lose access
iii) Or become inactive for a long time
…their digital wealth becomes permanently inaccessible.
There is no automatic way for heirs to inherit on-chain assets.
Traditional wills cannot access private keys.
Centralized exchanges are risky and require legal battles.
Self-custody wallets → if the owner dies, funds are lost forever.
👉 Billions of dollars in crypto are lost every year because owners never set up a digital inheritance method.
Trustchain provides a fully decentralized, automated, and tamper-proof way to transfer digital assets to designated heirs when the owner becomes inactive.
Instead of relying on lawyers, centralized exchanges, or sharing private keys, Trustchain uses an on-chain smart contract that manages inheritance securely and transparently.
🔐 1. Smart-Contract Based Inheritance
The contract stores:
Registered heirs
Their assigned percentage shares
The owner’s last activity (heartbeat)
A defined inactivity period (e.g., 30 days)
The entire inheritance logic runs without human intervention.
⏱️ 2. Automatic Inactivity Detection
The owner periodically calls heartbeat().
If the owner does not send a heartbeat within the set inactivity period, anyone can trigger the inheritance release.
This ensures assets are only transferred when the owner is truly inactive.
💸 3. Automatic Asset Distribution
Upon inactivity:
All ETH stored in the contract
(Optional) ERC20 tokens
…are automatically divided among the heirs according to their assigned shares.
This guarantees:
No disputes
No delays
No external permissions needed
🧱 4. Trustless and Tamper-Proof
Because the inheritance rules live on the blockchain, they cannot be:
Manipulated
Paused
Altered by third parties
Heirs can verify:
Their share
The owner’s activity
Contract balance
Release history
Everything is transparent and immutable.
🔄 5. Works Without Sharing Private Keys
The owner never needs to share:
Their wallet
Their seed phrase
Their passwords
This maintains complete security while still enabling inheritance.
