Scope of Our Smart Contract Development Services

Along with guaranteeing cybersecurity and efficiency of smart contracts, ScienceSoft also enables easier smart contract integration and updatability by implementing:

Oracles – off-chain interfaces to transfer real-world data to/from the blockchain-hosted contracts.
Proxy contracts – for storing transaction data (to prevent it from being lost after updates) and running delegatecall to set a newer version of the contract as a default one.

Design and development

Design of multiple smart contract logic scenarios.
Development of proxy contracts to facilitate updates and iterative development of smart contracts.
Built-in ‘contract self-destruct’ command for contract termination.

Audit, testing, and deployment

Testing to guarantee zero vulnerabilities.
Code reviews and audits.
Logic audit (in the presence of the involved parties) to ensure reflection of stipulated agreements.
Post-deployment contract testing (via test oracles).

Oracle development

Development of oracles for seamless integration with off-chain data sources (sensors, databases, bank systems, etc.)
Integration of oracles with smart contracts and businesses’ IT ecosystems.

Advantages of Smart Contracts Developed with ScienceSoft

Hack-proof

ScienceSoft employs proven smart contract coding best practices (variable stacking, merkle proofs, signer-, ownership- and rent exemption checks, etc.) to reduce gas consumption and eliminate loopholes in the smart contract logic. Our senior and lead developers also perform multi-round code reviews and code audits to prevent reentrancy, unsafe or dead code, outdated dependencies, and other logic vulnerabilities.

Amendable

ScienceSoft ensures easy smart contract updatability by introducing the proxy contract mechanism. Our smart contract developers also guarantee invulnerability of proxies by introducing dangerous function restrictions and avoid post-update conflicts of variables by separating variables from logic.

Business-friendly

Thanks to the centralized or decentralized oracles, ScienceSoft’s smart contracts are easy to integrate into a business ecosystem of any type and scale. Our developers can also design tailored ‘if/then’ smart contract scenarios to not immediately penalize certain clients. This way, you can be confident that the automatic nature of smart contracts won’t ruin your valuable business partnerships.
