The growing complexity of managing assets across multiple blockchain ecosystems inspired Atomix. With the rise of DeFi, users need a seamless way to transfer assets between different chains while accessing DeFi protocols without relying on centralized exchanges or bridge solutions. We wanted to build a solution that would empower users with trustless, secure, multi-asset atomic swaps and provide immediate access to decentralized finance services like staking, lending, and yield farming across different blockchains—all within a single, cohesive platform.
Atomix is a multi-asset cross-chain atomic swap protocol that allows users to exchange tokens between major blockchains (Tron, Ethereum, Binance Smart Chain, and more) without intermediaries. What makes Atomix special is its DeFi composability—after performing atomic swaps, users can directly interact with DeFi protocols on the destination chain, like lending or staking their swapped tokens. This creates a seamless flow from asset transfer to financial engagement, allowing users to maximize the utility of their assets across chains while remaining fully decentralized and secure.
We built Atomix using smart contracts based on Hashed Time-Locked Contracts (HTLCs) to ensure atomicity and security of swaps. The project was designed on Solidity, deploying contracts on the Tron, Ethereum, and Binance Smart Chain testnets. We integrated a cross-chain liquidity pool to provide liquidity for swaps and developed smart contracts to manage DeFi interactions post-swap. The front-end UI was built to simplify the user experience, ensuring users could swap and engage with DeFi protocols in just a few steps.
Key components:
One of the biggest challenges was ensuring cross-chain compatibility and the security of atomic swaps. Implementing HTLCs in a multi-chain environment required extensive testing to ensure that funds were securely locked and unlocked based on the pre-agreed conditions. Integrating DeFi protocols post-swap introduced additional complexity, as we had to ensure seamless handoffs from one blockchain to another without any loss of functionality or security. Liquidity provision and management were also challenging, especially in creating dynamic incentives for liquidity providers.
We are particularly proud of successfully implementing a fully decentralized cross-chain atomic swap system that supports multiple asset types (TRC-20, ERC-20, BEP-20) and offers real-time access to DeFi protocols post-swap. By eliminating intermediaries, we’ve built a truly trustless, non-custodial solution that provides users with a seamless DeFi experience across chains. Additionally, creating a user-friendly interface that simplifies what is otherwise a complex process is a major achievement.
