Project Overview
Emplifai was a DeFi protocol focused on liquidity harvesting and yield farming across EVM-compatible chains.
The platform aimed to help users access yield opportunities through custom vaults connected to external protocols such as Allbridge pools. These vaults needed to handle staking, reward logic, protocol-specific flows, and secure user interactions.
I worked on the project as the Lead Blockchain Developer at Analog Mutations, alongside a team of blockchain developers. My main responsibility was developing, testing, and integrating smart contracts for yield farming vaults.
The Challenge
Every integrated protocol had its own reward structure, staking mechanism, and interaction flow. The vault contracts could not be treated as simple deposit and withdrawal contracts.
Each integration required close analysis of how rewards were generated, how staking worked, how funds moved between contracts, and how the vault logic should adapt to external protocol behavior.
The contracts also needed thorough testing before handoff for team deployment because DeFi vaults directly handle user funds and reward calculations.
My Contribution
- Smart-contract delivery
Developed Solidity smart contracts for custom yield farming vaults.
- Vault logic
Built liquidity harvesting, staking, reward, deposit, and withdrawal behavior.
- Protocol integrations
Integrated vault behavior with external protocols, including Allbridge pools.
- Reward mechanisms
Analyzed protocol-specific staking and reward structures and applied custom logic where required.
- Foundry testing
Created unit and integration tests covering staking, rewards, deposits, and withdrawals.
- Team collaboration
Worked with other blockchain developers on code quality, deployment strategy, and repository handoff.
- Reliable delivery
Completed and submitted the assigned smart-contract work on time.
Key Features Delivered
- Yield vault contracts
Custom smart contracts supporting liquidity harvesting and yield farming.
- Allbridge support
Integration behavior for Allbridge pools and their protocol-specific flows.
- Cross-protocol rewards
Custom handling for different staking structures and reward mechanisms.
- Vault interactions
Secure deposit, withdrawal, staking, and reward calculation behavior.
- Foundry test suite
Unit and integration tests covering realistic vault and reward scenarios.
- Deployment handoff
A structured GitHub repository prepared for team review and deployment.
Outcome
The assigned smart-contract work was completed and submitted on time. The result was a set of thoroughly tested, production-ready contracts that the team could access, review, and deploy from the GitHub repository.
Emplifai demonstrates my ability to work on technical DeFi infrastructure, particularly yield-vault logic, cross-protocol integrations, reward mechanisms, and Foundry-based smart-contract testing.
