The problem Tracto solves

Complexity of Cross-Chain Transactions

Cross-chain transactions, which involve transferring assets between different blockchain networks, are complex due to the absence of a unified protocol for inter-blockchain communication. This complexity often leaves users struggling with technical details and compatibility issues between different blockchains.

Tracto's Mobile-Optimized Simplification Approach

Tracto revolutionizes this process by offering a mobile-optimized platform that simplifies cross-chain transfers. This mobile application allows users to execute transactions seamlessly across different networks without requiring in-depth knowledge of the underlying blockchain technologies. This mobile-centric approach makes digital finance more accessible and convenient, especially for users who rely heavily on mobile devices.

Enhancing Security Through Tracto's Escrow Solution

Tracto tackles these security challenges by integrating trusted wallet solutions and employing advanced encryption methods. Additionally, its escrow-based service adds a layer of security, ensuring that assets are securely held until all transaction conditions are met. This approach significantly mitigates the risk of fraud and unauthorized access, safeguarding users' assets and transaction details.

High Transaction Costs and Inefficiencies

One major issue in blockchain transactions is the high cost, often exacerbated by network congestion. These costs are even more pronounced in cross-chain transactions, which typically require multiple steps and transactions across different networks.

Challenges we ran into

Building a project as innovative and complex as Tracto inevitably comes with its share of challenges. From technical hurdles to conceptual obstacles, each challenge provided an opportunity for learning and improvement. Below are some of the specific challenges we encountered and the strategies we employed to overcome them:

1. The Challenge of Integrating Okto Wallet
   Integrating Okto Wallet into Tracto's infrastructure presented a unique set of challenges. The Okto SDK, being a relatively new and complex technology, initially posed difficulties in terms of compatibility and functionality within our existing system but we figured stuff out and integrated it

2. Cross-Chain Interoperability
   Challenge: Achieving seamless interoperability between different blockchain networks was a significant technical hurdle, given the distinct protocols and consensus mechanisms of each blockchain.

Solution: We tackled this by integrating a series of smart contracts and cross-chain communication protocols. We also conducted extensive testing on networks like Polygon Mumbai testnet, Linea, Mantle, Scroll, and Arbitrum to ensure compatibility and smooth operation across these varied platforms.

3. Accurate Gas Fee Estimation
   Challenge: Providing users with accurate gas fee estimates for transactions, especially in a fluctuating market, was complex. Incorrect estimations could lead to failed transactions or unnecessarily high fees.

Solution: To address this, we integrated the Metamask GAS API with enhanced algorithms that consider current network congestion and typical transaction times. This integration provided a more reliable estimation of the required gas fees.

4. User Interface and Experience
   Challenge: Designing a user interface that was both intuitive and feature-rich was challenging, especially considering the diverse user base with varying levels of blockchain expertise.

Solution: We focused on a design-first approach, prioritizing simplicity and clarity in our UI/UX design.
