Project Summary

Antier Solutions developed and implemented secure, gas-efficient smart contracts, integrated Chainlink price feeds, and built a REST and Web3-enabled API layer for a crypto payment solutions firm. They set up local testnets and prepared documentation for auditors and developers. The provider delivered a functional DeFi prototype in under four months, the smart contracts passed a third-party audit with no severe vulnerabilities, and the client raised €1.1M in seed funding shortly after MVP launch.

Key Challenges

Deliver secure, gas-efficient smart contracts.
Ensure the contracts were simple to integrate with a React-based frontend.

Project Deliverables

Smart contracts for liquidity pools, staking, yield calculation, and exit fees.
Chainlink price feed and Oracle integrations.
REST and Web3-enabled API layer.
Local testnets for prototyping.
Documentation for auditors and developers.
