Build Wars Winner Spotlight: DCAi

The limits of traditional DCA‍

Standard DCA (Dollar Cost Averaging) is designed to remove emotion from investing, yet most current implementations only automate the purchasing process. This leaves users responsible for monitoring their positions and making selling decisions, which often reintroduces emotional bias during volatile market periods. In addition, traditional tools execute buys blindly based on a calendar schedule, even when market conditions such as low liquidity make the transaction inefficient.

A Complete Execution System 

DCAi addresses these gaps by treating the investment strategy as a complete execution system rather than a simple recurring payment. The platform requires users to define their entry parameters and profit targets upfront. These rules are then enforced by a Smart Contract, ensuring that the entire lifecycle of the trade is automated. This removes the need for the user to intervene or exercise willpower once the strategy is deployed.

How it Works 

The system optimizes performance through two specific mechanisms. First, an automated execution layer monitors on-chain data to validate that scheduled buys occur under favorable liquidity conditions. Second, the contract includes an "Auto-Harvester" feature that continuously tracks the average entry price. When the position reaches the pre-defined profit threshold, the system automatically swaps the assets back into USDC to secure the gains.

DCAi secured 1st Place in the DeFi Track because it delivered a fully functional system that solves a genuine behavioral issue in decentralized finance. The judges recognized its ability to translate the theoretical need for investment discipline into enforceable on-chain logic.

Technical Specs

Architecture DCAi utilizes a factory design pattern where a central Parent Contract serves as a registry. This parent contract deploys a unique Child Contract for each individual user strategy. This structure ensures that each strategy holds its own funds and logic in complete isolation, which prevents pooled risk and simplifies the auditing process.

The logic includes a personalized analysis layer called "Hodloth" that evaluates market cap and tokenomics to adjust execution parameters for specific assets. The system is built on MultiversX to leverage fast finality and low transaction costs, allowing for frequent automated checks without incurring high fees.
