Smart-contract deployments

A smart-contract is a program that lives on the blockchain and automatically executes its built-in logic (transfers, rules, conditions) without an intermediary. Deployment is the development of such a contract (usually Solidity for EVM networks), its testing and rollout to the network, after which it works publicly and autonomously. Honestly about irreversibility and immutability, this is key: contract deployment is irreversible, and most contracts are immutable after deployment by nature (that is the point — no one can 'quietly' change the rules). The flip side: if the contract has a bug, it cannot simply be patched — you have to deploy a new contract and migrate, which is complex and costly, and funds already lost to the bug cannot be returned. So the cost of an error in a smart-contract is incomparably higher than in ordinary code. Honestly about mandatory pre-deployment checking: precisely because of irreversibility, the contract must be thoroughly checked BEFORE deployment — with testnet tests and code-review (1075). For contracts with large sums at stake we honestly recommend an additional formal security audit by a specialized firm. Deploying an unchecked contract with real funds is irresponsible, and we do not do that. Honestly about 'no security guarantee': even after tests, review and an audit, a 100% invulnerability guarantee does not exist — hacks of audited contracts are known. We reduce risk as much as possible but do not promise absolute security; anyone promising it is lying. Honestly about gas and networks: deployment and each contract transaction cost a network fee (gas), sometimes significant and unpredictable; this must be budgeted. The choice of network affects cost and security. Honestly about 'a contract is not magic': a smart-contract does exactly what is coded. It is not 'smart' in the human sense, does not adapt and does not forgive logic errors. Quality is in well-thought-out logic and checking, not in the mere fact of 'we have a smart-contract'. Honestly about the effect: we give a developed, tested and deployed contract with code-review, but with an honest warning about irreversibility and the limits of guarantees. Honestly about access: clear contract logic, readiness for checking/audit, a gas budget are needed. An important boundary: this is contract development and deployment; code-review/audit — 1075; token/launchpad — 1073; DeFi — 1076. The base price starts from 130,000 ₽ (depends on logic complexity).

• A smart-contract with specific logic, deployed to a network, is needed.
• Self-deployment is risky — a bug is irreversible and costs funds.
• It is underestimated that a contract usually cannot be changed after deployment.
• There is no pre-deployment checking of the contract (tests, review, audit).

• Smart-contract development for your logic (Solidity etc.)
• Testnet testing before deployment
• Contract code-review (not a formal audit — see 1075)
• Deployment to the chosen network accounting for gas
• Honest boundaries (deployment is irreversible; the contract is immutable; no security guarantee; for large sums — a formal audit; gas costs)
• An honest recommendation for a formal audit for large sums
• Contract documentation and handover
• Review with you

• A developed, tested and deployed smart-contract
• Code-review and tests before deployment (risk reduction)
• An honest assessment: is a formal audit additionally needed
• Honest boundaries (deployment irreversibility; immutability; no security guarantee; gas costs)

• We discuss the contract logic and sums at stake, assess risks
• We develop, test on testnet, do code-review
• We deploy accounting for gas; for large sums we recommend a formal audit; hand over to you

• If a bug is found in the contract after deployment — will we fix it?

  Usually no, and this is critical, honestly: deployment is irreversible, and most contracts are immutable after deployment. A bug cannot simply be patched — you have to deploy a new contract and migrate (complex, costly), and funds already lost to the bug cannot be returned. So we thoroughly check the contract BEFORE deployment (tests, code-review — 1075, a formal audit for large sums). Deploying an unchecked contract with real funds is irresponsible, and we do not do that.

• After tests and review, is the contract definitely safe?

  It cannot be guaranteed, honestly: even after tests, code-review and a formal audit, a 100% invulnerability guarantee does not exist — hacks of audited contracts are known. We reduce risk as much as possible (tests, review, an audit recommendation for large sums) but do not promise absolute security. Anyone promising '100% safe' is lying. The cost of an error is irreversible, so we are honest about the limit.

• Will a smart-contract by itself make the system better?

  No, honestly: a contract does exactly what is coded — it is not 'smart' in the human sense, does not adapt and does not forgive logic errors. Quality is in well-thought-out logic and thorough checking, not in the mere fact of 'we have a smart-contract'. Plus deployment and transactions cost gas, sometimes significant. We honestly do not pass the presence of a contract off as an improvement by itself.
