Question 1

How much does smart contract development cost?

Accepted Answer

Cost scales with the number of contracts, the complexity of the economic logic, and the depth of testing required. A standard token with vesting is a small engagement, while a lending protocol with oracles and liquidations is a multi-month build. External audit fees are a separate line item and should be scoped and scheduled early, since reputable auditors book out weeks ahead.

Question 2

Which chains and languages are used for smart contract development?

Accepted Answer

Most production smart contract work is Solidity on Ethereum and EVM chains such as Arbitrum, Base, and Polygon, where tooling and auditor coverage are strongest. Non-EVM options like Rust on Solana make sense when there is a real reason to use them, such as throughput or an existing user base on that chain. Chain choice is ultimately a business decision about users, liquidity, and cost, and it belongs in the specification phase, not after the code is written.

Question 3

Should a development team audit its own smart contracts?

Accepted Answer

No. Development teams should test aggressively in-house with unit tests, fuzzing, and fork simulations, but the final audit must be independent, so a reputable third-party firm should perform it. The developer's role is to prepare the audit package, answer auditor questions, and remediate findings through re-review. Self-audited code is widely treated as a red flag for any contract that will hold meaningful value.

Question 4

What deliverables should a smart contract project include?

Accepted Answer

A complete handover includes the contract source under the client's ownership, the full test suite, deployment scripts, verified contracts on the block explorer, and documentation of every admin function and key. Monitoring setup and an incident playbook belong in the package too. The test of a good handover is that the owning team, or any competent firm, can maintain the system without the original developers.

Question 5

What actually drives the cost of a smart contract project?

Accepted Answer

Complexity of the state machine and the value at risk drive cost more than lines of code. A simple token is days of work, while a lending protocol or cross-chain system carries months of design, testing, and audit cycles. External audits are a separate budget line, typically quoted per week of auditor time, and complex protocols may need two firms. Plan for the audit and remediation phase to take as long as initial development on high-value systems.

Question 6

Do we need an external audit if you already test heavily?

Accepted Answer

If the contract will hold meaningful third-party funds, yes. Internal testing and review catch most issues, but an independent firm with fresh eyes and different tooling is a distinct layer of defense, and many partners, exchanges, and institutional users will ask for the report. For lower-stakes contracts, a lighter internal review plus automated analysis can be a reasonable trade-off. We help you scope which level of assurance the deployment actually needs.

Question 7

Should our contracts be upgradeable or immutable?

Accepted Answer

It depends on who your users are and what they need to trust. Immutable contracts are simpler to reason about and easier to market to sophisticated users, but a bug means migration. Upgradeable proxies let you patch, but concentrate power in whoever holds the admin keys, which becomes a security and sometimes regulatory question. A common middle ground is upgradeable contracts with a timelock and multisig, moving to immutability or on-chain governance as the protocol matures.

Question 8

Which chain should we deploy on?

Accepted Answer

Start from where your users and liquidity are, then weigh fees, finality, and tooling maturity. Ethereum mainnet offers the deepest liquidity and strongest security but high gas costs for frequent interactions. L2s such as Arbitrum, Base, and Optimism cut fees dramatically with near-identical EVM tooling, which suits consumer-facing applications. Multi-chain deployment is possible but multiplies audit surface and operational overhead, so we usually recommend proving the product on one chain first.

Question 9

How do you handle private keys and deployment security?

Accepted Answer

No production contract should be controlled by a single private key on a laptop. We use hardware wallets or key management services for deployments, transfer ownership to a multisig such as Safe immediately, and put sensitive parameter changes behind timelocks. Deployment scripts are rehearsed on forks so the mainnet run has no improvisation. We also document exactly which addresses hold which powers so your team can audit control at any time.

Question 10

What do you need from us to start?

Accepted Answer

A clear description of the economic mechanism you want, even in plain language, plus any existing documentation, tokenomics models, or prior code. From that we produce a technical specification and a scoped estimate before development begins. If you have an existing codebase, we typically start with a review to establish its state before extending it. Legal and regulatory review of the token or protocol design is your counsel's domain, but we flag design choices that commonly attract scrutiny.
