4IRE Hiring and engagement model
Full-time hiring
The 4IRE team of smart contract coders is available for full-time engagement in your project via staff augmentation. You can quickly close talent gaps and hire a smart contract developer for your project, knowing that they will be fully dedicated to your tasks on a full-time basis, though working remotely from the 4IRE office.
Part-time hiring
Those who don’t need smart contract developers for full-time employment can opt for the part-time collaboration model. This way, you get a flexible and cost-efficient solution to cover your project tasks and ensure that all smart contract-related development work is completed on time. The part-time coders will work on several projects simultaneously, attending to your project when you need them to.
Time & Material
This alternative is the most flexible and affordable for companies requiring smart contract development staff for separate tasks emerging from time to time in the course of project work. You only pay for the hours our coders spend on your tasks, never overpaying for coder recruitment and maintenance in the in-house team.
Our Smart Contract Development Services
Web3 is the new word in the digital space, and smart contracts fuel the functioning of Web3 projects. Thus, every forward-looking business should tap into the innovative and quickly expanding blockchain niche to reap its immense potential and derive business revenue. 4IRE is ready to help you transition to the Web3 digital space with secure, robust, and functional smart contracts of any complexity. We use a large mix of blockchain technologies and tools to customize solutions to unique business needs and help you outperform the competitors in your niche.
Smart Contract Architecture
Our team can analyze your project needs and propose custom-tailored smart contract architecture that will amp up your competitive advantages and bring your product to a new level of operational efficiency, execution speed, richness of functions, and user safety.
Smart Contract Development
4IRE engineers can build smart contracts for your project from scratch using state-of-the-art blockchain technologies and tools. We design smart contract logic with security and functionality in mind and customize it to your unique project needs and expectations.
Smart Contract Audit
Audits are a vital part of any Web3 project development. The crypto space is very unsafe, and any loophole in your smart contracts can result in asset leakage. We conduct manual and automated testing of smart contracts to ensure they have bulletproofed security.
Smart Contract Optimization
You may already have a functioning Web3 project but opt for its scaling and optimization. 4IRE analysts can comprehensively review your smart contract logic and offer flexible solutions to enhance their speed, safety measures, and performance.
