Linea LEGACY is a decentralized smart will solution on Linea Chain, ensuring secure, automated inheritance of digital assets, educational funds, and intellectual property.
In an increasingly digital world, our assets, educational achievements, and intellectual property often exist solely as encrypted data accessible only through private keys and seed phrases. The loss of these credentials can lead to irreversible loss, denying our loved ones and future generations the inheritance of our digital wealth and educational legacies.
Linea LEGACY offers a groundbreaking solution to this problem: a trustless, automated, and decentralized smart will system built on the secure and scalable Linea Chain. By leveraging the power of blockchain technology, Linea LEGACY allows individuals to define specific conditions under which their assets, scholarships, research, and educational wealth will be securely and automatically distributed, ensuring that their legacy endures.
This isn't just about transferring cryptocurrency; it's about securing a brighter future for education, research, and the passing down of invaluable digital knowledge.
Linea LEGACY is built upon a foundation of these key principles:
Trustless Automation: The entire inheritance process is governed by smart contracts, eliminating the need for intermediaries and ensuring transparent, verifiable execution. Once conditions are met, asset distribution is automatic.
Focus on Education and Intellectual Property: While traditional inheritance focuses primarily on financial assets, Linea LEGACY expands the scope to include educational funds, research data, digital certificates, and NFTs representing intellectual property, ensuring these invaluable resources are passed on effectively.
Enhanced Security: The use of blockchain technology, combined with robust security measures implemented in the smart contracts, provides a level of security far exceeding traditional methods of inheritance planning.
Community-Driven Innovation: Linea LEGACY is designed to be an open and collaborative project, encouraging contributions from developers, educators, and the wider blockchain community to continuously improve and expand its capabilities.
Seamless User Experience: Despite the complex technology underpinning the system, Linea LEGACY is designed with a user-friendly interface and seamless integration with popular wallets like MetaMask, making it accessible to users of all technical skill levels.
Linea LEGACY's comprehensive functionality is provided through these main features:
Recognizing that different assets and legacies require different distribution strategies, Linea LEGACY offers two distinct will types:
Normal Wills: Designed for simple, single-beneficiary inheritance. The testator (the will creator) locks a specified amount of Linea cryptocurrency into the contract, designates a beneficiary, and sets a custom inactivity lock (default: 10 years, customizable for testing purposes). If the testator fails to "ping" the system to confirm their continued activity within this timeframe, the beneficiary becomes eligible to claim the inheritance.
Milestone Wills: Intended for multi-phase distributions, particularly well-suited for educational funding and research grants. The testator can define a detailed release schedule with education-based triggers, such as graduation, course completion, achievement of specific research milestones, or enrollment in a degree program. These pre-programmed releases ensure funds are disbursed in a structured manner, supporting long-term educational goals.
These features safeguard educational assets and ensure the continuity of scholarships and research initiatives:
Secure Funding for Students: Programmed releases enable secure funding for students.
Automated Scholarship Management: Institutions can use blockchain-verified grants with automatic disbursement.
Learning Resource Inheritance: Certificates, research papers, NFTs, etc., are safely transferred.
Time-based automation is at the heart of Linea LEGACY:
Adjustable Activity Check: Enables you to customize your will.
One-Year Withdrawal Cooldown: Prevents claims immediately following the triggering event.
Milestone-Specific Release Schedules: This is crucial for educational inheritance.
Security is paramount. Linea LEGACY incorporates:
Immutable Beneficiary Assignments: Protects against malicious beneficiary changes.
Anti-Frontrunning Protection: Prevents unauthorized claims.
Signature-Based Claim Verification: Ensures only valid beneficiaries receive assets.
Fund Locking: Assets remain locked in the smart contract until conditions are met.
To ensure broad accessibility, Linea LEGACY leverages:
MetaMask SDK: Streamlines connecting and interacting with the application for MetaMask users.
Wagmi: Provides a set of React Hooks for easily accessing Ethereum data and interacting with smart contracts, simplifying the development process.
The Linea LEGACY smart contract is the core of the system, written in Solidity and designed for efficient and secure operation on the Linea Chain Testnet. The architecture comprises these key components:
NormalWills Mapping: Stores the details of each Normal Will, indexed by the testator's address. The struct contains the beneficiary address, the amount of Linea locked in the will, the last activity timestamp, the claim wait time, a description of the will, and a boolean indicating whether the will has been claimed.
MilestoneWills Mapping: Manages the details of Milestone Wills, also indexed by the testator's address. This mapping stores a list of release schedules, each defining a specific milestone and the amount of Linea to be released upon achieving that milestone.
hasNormalWill Mapping: A boolean mapping indicating whether a given address has created a Normal Will. This is used for quick lookups to determine if a testator has an active will.
Access Control: The contract incorporates access control mechanisms to ensure that only authorized users can perform certain actions, such as creating wills, depositing funds, and claiming inheritances.
function getNormalWillAsBeneficiary(address _beneficiary) external view returns (address[] memory owners, uint256[] memory amounts) {
uint256 count = 0;
for (uint256 i = 0; i < willOwners.length; i++) {
address user = willOwners[i];
if (hasNormalWill[user] && normalWills[user].beneficiary == _beneficiary && !normalWills[user].isClaimed) {
count++;
}
}
owners = new address[](count);
amounts = new uint256[](count);
uint256 index = 0;
for (uint256 i = 0; i < willOwners.length; i++) {
address user = willOwners[i];
if (hasNormalWill[user] && normalWills[user].beneficiary == _beneficiary && !normalWills[user].isClaimed) {
owners[index] = user;
amounts[index] = normalWills[user].amount;
index++;
}
}
return (owners, amounts);
}
Linea LEGACY is a continuously evolving project with a clear roadmap for future enhancements:
Cross-Chain Support: Extending Linea LEGACY's functionality beyond the Linea Chain, enabling users to manage assets across multiple blockchain networks.
NFT Deposits: Allowing users to deposit NFTs representing educational certificates, research papers, and other digital assets into their wills, securing these valuable items for future generations.
Decentralized Scholarship Management: Empowering universities and other educational institutions to allocate and distribute grants via smart contracts, creating transparent and efficient scholarship programs.
Enhanced Block Explorer Integration: Providing users with more detailed and user-friendly information about their wills and transactions through seamless integration with Linea Chain's block explorer.
Direct Fund Transfers: Beneficiaries will soon be able to move funds from the locked contract to specific wallet addresses for direct payments and financial management instead of just holding assets.
Linea LEGACY is more than just a project; it's a movement. We invite developers, educators, blockchain enthusiasts, and anyone passionate about securing the future of digital and educational wealth to contribute to the project.
