    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.
