Project Description

DeFiKeep is a minimalistic yet powerful smart contract-based application designed for long-term token locking on EVM-compatible blockchains.

The core concept is simple: users can securely lock their native tokens (like BTC, ETH, etc.) for a specified duration, ranging from days to centuries, ensuring that these assets remain untouched and inaccessible until the unlock date!

What makes DeFiKeep uniquely valuable is its focus on disciplined financial behavior. By removing access to tokens for a fixed period, DeFiKeep helps users:

  • Avoid impulsive decisions like panic-selling or FOMO-buying (often driven by market noise).
  • Set up trust-like vaults for savings, inheritance, or planned gifting.
  • Take full advantage of long-term value appreciation, particularly useful in ecosystems like Bitcoin where historical data shows exponential growth over time.
  • The ability to transfer ownership of locked funds enables dynamic financial management, inheritance planning such trust funds, or long term DCA-locked strategies.

The nuanced ability to transfer ownership of locked funds introduces flexibility, security, and innovation to the DeFi space. While non-transferable locked funds serve well for simple use cases like savings plans and long-term investments, the transferable feature allows for customization, dynamic management, and composability with other DeFi products, offering a whole new set of possibilities for both individual users and decentralized financial platforms.

How it's Made

DeFiKeep is a robust EVM-compatible smart contract solution designed to allow users to securely lock tokens for long periods, with a special feature that enables the transfer of ownership of the locked funds.

Built using Solidity, the contract governs the rules for locking tokens, transferring ownership, and ensuring secure withdrawals after the lock period ends. It is designed to be compatible with Ethereum and other EVM chains, such as Rootstock, Citrea, Flow EVM, giving users flexibility to interact with multiple decentralized networks.

The frontend of DeFiKeep is built using HTML5, CSS3, and JavaScript, with Web3.js enabling seamless interactions with the blockchain. The UI allows users to connect their wallets (like MetaMask), lock tokens, transfer ownership, and monitor locked funds. This integration makes the process smooth, with the Web3.js library handling transactions and smart contract interactions.

The smart contract itself is optimized for gas efficiency and security, incorporating the latest Solidity features to prevent reentrancy attacks and minimize transaction costs.

Additionally, the system supports composability, making it easy to integrate with other DeFi protocols. For instance, users can lock tokens in DeFiKeep and potentially interact with liquidity pools or other DeFi services.

The design and architecture of DeFiKeep prioritize both simplicity and user-friendliness and the flexibility required for advanced financial strategies.

With these features, DeFiKeep aims to become an essential tool for secure, long-term token storage while enabling dynamic financial management, inheritance planning, and future DeFi composability.
