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contracts – for storing transaction data (to prevent it from being lost after updates) and running delegatecall to set a newer version of the contract as a default one.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.

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and lead developers also perform multi-round code reviews and code audits to prevent reentrancy, unsafe or dead code, outdated dependencies, and other logic vulnerabilities. |
|
|
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. |
