Web3 & Smart Contract
Development

Solidity and Solana smart contracts, wallet-connected dApps, and the web and mobile front-ends around them. A two-developer Web3 studio that ships products people actually use.

── WHAT WE BUILD ─────────────────────────────────────────

Inventagious is a two-developer Web3 development company. We write the smart contracts, build the wallet-connected front-end that uses them, and run the backend that indexes on-chain data — so you deal with one team for the whole product instead of an agency handing work between departments.

On the contract side we ship Solidity for Ethereum, Base, Polygon and other EVM chains, and Anchor programs for Solana. Every contract comes with a test suite, deployment scripts, and documentation your auditors can work from. We have built escrowed crowdfunding flows, token and NFT contracts, and event listeners that keep off-chain databases in sync with on-chain state.

Need a smart contract builder or no-code deploy flow inside your own product? We have built those too — drag-and-drop configurators that compile to audited templates, plus the dashboards founders use to monitor what is deployed.

── FAQ ───────────────────────────────────────────────────

Q: What does a Web3 development company do?

A: A Web3 development company builds decentralized applications: the smart contracts that run on chains like Ethereum and Solana, the wallet-connected front-ends people use, and the backend services that index on-chain data. Inventagious does all three as one two-developer team.

Q: Do you audit smart contracts?

A: We build with security-first patterns, full test coverage, and static analysis, and we recommend an independent third-party audit before any production release that holds real value. We prepare the documentation auditors need and fix findings after the audit.

Q: Which chains do you support?

A: Ethereum, Base, Polygon, Arbitrum and other EVM-compatible chains with Solidity, plus Solana with Anchor. We pick the chain that fits the product, not the other way around.

Q: How much does smart contract development cost?

A: It depends on the chain, contract complexity, and whether you also need a front-end or backend. We scope a fixed price after a short discovery call — no retainers or agency overhead.

Q: How long does a Web3 project take?

A: Timelines depend on scope. We share a milestone plan after the discovery call and ship in short iterations, so you see working contracts and UI early instead of waiting for a big-bang launch.

Q: Can you take over or upgrade an existing smart contract?

A: Yes. We review the existing code, add tests where they are missing, and ship upgrades using proxy patterns or migrations where appropriate.

Q: Can you build both web and mobile versions?

A: Yes — we handle web, iOS, and Android. One studio for the full product surface, including wallet connections on mobile.
