Smart contract optimization

We developed an optimized smart contract for ENTR, a major player in the DEX aggregator market, which provides users with access to decentralized token exchanges across hundreds of pools on various blockchains.

• Gas Consumption Optimization The more complex the logic of a smart contract, the more gas is consumed during its execution on the network, leading to higher transaction fees for the end user. Our challenge was to investigate ways to streamline and optimize the contract to ensure Entr users benefit from the most cost-effective trades possible.
• Trade Route Optimization When building trade routes, there is always a trade-off between a complex route—splitting amounts across multiple pools, swapping through several tokens, etc.—and the cost of such a trade. It was crucial for us to strike a balance between obtaining a favorable exchange rate through optimal routing and minimizing the gas cost associated with the trade.
• Contract Selection and Flow Optimization Entr utilizes different smart contracts for different exchange paths. Our task was complicated by the need to understand the mechanics of these exchanges to a certain level and determine which smart contract was most worth optimizing. This would allow us to route the flow of cost-effective trades through the most suitable contract.

• Architectural Assessment and Optimization We conducted a thorough assessment of the architecture of Entr's smart contracts and exchanges. Based on our findings, we devised the most optimal architectural solution to streamline the exchange flow, minimizing the cost of trades.
• Proxy Contract Optimization We focused on optimizing the proxy contract, enabling cost-effective trades with minimal gas usage. This optimization was implemented at the proxy contract level, ensuring that the trades are not only efficient but also gas-light.

• Effective Cost Reduction Our strategy proved successful as we reduced the cost of trades covering about 80% of all exchanges on the Entr platform.
• Significant Gas Savings The optimization resulted in gas savings ranging from tens of thousands to hundreds of thousands of gas units. This translates to savings of several tens to several hundreds of percent, depending on the trade route.

We successfully optimized the smart contract for Entr, delivering a killer feature that provides them with a significant competitive advantage in the market. This optimization not only enhanced the efficiency of their platform but also ensured a better user experience through lower transaction costs.
