Blockchain Development Services

Blockchain development costs roughly $10,000–$40,000 for a proof of concept, $40,000–$120,000 for an MVP, $120,000–$350,000 for a full production product, and $300,000–$600,000+ for an enterprise-grade system. Final price depends on platform, integrations, compliance burden, and security depth.

A proof of concept takes 3–8 weeks, an MVP 2–5 months, a full production build 4–10 months, and an enterprise system 8–18 months. Timeline is driven mostly by integration complexity, audits, and compliance reviews rather than raw feature count.

A Layer 1 is a base blockchain like Ethereum, Solana, or BNB Chain that settles transactions and runs consensus. A Layer 2 is built on top of an L1 to increase speed and lower fees, such as Arbitrum, Base, or Polygon, inheriting the L1's security while batching transactions off-chain before settling them.

Choose Ethereum for the deepest liquidity and tooling, Layer 2s like Arbitrum, Base, and Polygon for low fees with Ethereum security, Solana for high throughput and low cost, and BNB Chain for cheap EVM deployment. Private or permissioned chains like Hyperledger fit enterprise data-privacy use cases.

Plan for development to be only about 40% of your 3-year spend. Maintenance, security re-audits, gas and oracle fees, and infrastructure make up the rest. A practical rule of thumb is to multiply the quoted build cost by 2–2.5x for a realistic 3-year budget.

Start with a tightly scoped MVP or proof of concept, reuse audited open-source libraries like OpenZeppelin, pick a low-fee Layer 2 instead of Ethereum mainnet, and define scope precisely before building. Most overspend comes from vague scope and unnecessary complexity, not from engineering rates.

A PoC is a minimal build that validates the core technical logic and feasibility before full development. It typically costs $10,000–$40,000 and runs 3–8 weeks. It's worth it when your idea is novel, investors need de-risking, or you're unsure a blockchain is even the right tool.

Blockchain is the right fit when you need trustless settlement, shared state between parties who don't trust each other, verifiable ownership, or programmable tokens. If a normal database with good access control solves it, you probably don't need a blockchain—and an honest partner will tell you that.

Finance and DeFi, real estate and RWA tokenization, supply chain, gaming, healthcare records, and digital identity are the heaviest adopters. The common thread is a need for transparency, asset provenance, automated settlement, or fractional ownership.

Yes. Common integrations include wallet connect and login, on-chain payment rails, tokenization of existing assets, smart-contract automation behind a familiar web or mobile UI, and oracle feeds. The blockchain layer sits behind APIs so end users don't need crypto expertise.

A full-cycle partner delivers consulting and architecture, smart contract development and audits, backend and indexer infrastructure, web and mobile front-ends, wallet and exchange integrations, deployment, and post-launch maintenance. Marshall covers this end-to-end across EVM chains, Solana, and Layer 2s.

Gas affects ongoing operating cost, not build cost. On Ethereum mainnet, moderate usage can run $3,000–$8,000/month; on Polygon or other Layer 2s it can be $200–$500/month. Choosing the right chain and batching transactions keeps gas predictable.

Public blockchains like Ethereum and Solana are open, permissionless, and decentralized—anyone can transact. Private or permissioned blockchains restrict who can read and write and are run by known entities, giving fixed costs and data privacy. Enterprises often choose private chains; consumer and DeFi products use public ones.

Look for relevant shipped projects in your niche, in-house audit and security capability, transparent layer-by-layer cost breakdowns, clear post-launch support terms, and references. Avoid black-box quotes and any partner that excludes the security audit from the proposal.
