Smart contracts and blockchain products, built to be trusted

Blockchain projects carry real money and real risk, so they are scoped carefully before anything is built. Tell us what you want to achieve. We will tell you honestly whether it needs a blockchain, what it takes, and what it costs.

Price: Custom quote, priced after we scope your project.

What a blockchain project actually needs

Most of the work is not the smart contract. These are the parts every serious project has to get right.

1. A clear reason for a blockchain Where trust, ownership or transparency across parties is the real problem. If a normal database does the job, we will say so. Output: Feasibility note.
2. The right network Ethereum, a Layer 2, Solana or a private chain: chosen for your users, fees, speed and ecosystem, not for hype. Output: Chain recommendation.
3. Smart contracts The on-chain logic: tokens, rules, payments, permissions. Written to be small, tested heavily and upgradeable only where it is safe to be. Output: Tested contracts.
4. Wallets and a front end Sign-in with wallets, transactions people can understand, and an interface that does not require them to know what gas is. Output: Web or mobile app.
5. Backend, data and indexing Blockchains are poor at searching. Indexers, APIs and databases make your app fast and your data usable. Output: APIs and dashboards.
6. Security review and audit Internal review, automated analysis, testnet runs and an independent audit for anything that holds value. Output: Review report.
7. Legal and compliance check Tokens, securities, payments and data rules differ by country and change often. Your lawyer signs off; we build to their brief. Output: Compliance checklist.
8. Launch, monitoring and upkeep Deployment, key management, alerts, upgrades and incident response once real users and real money are involved. Output: Runbook and monitoring.

• DAOs and on-chain governance (Community): Voting, treasuries and proposals for communities and organisations, with safeguards against capture. Voting, Treasury, Multisig, Proposals.
• Creator and community platforms (Community): Memberships, tipping and revenue sharing between creators and their supporters. Memberships, Tipping, Splits, Gated content.

AI and blockchain, working together

AI decides and creates. Blockchain proves, enforces and settles. Together they let software act on its own while staying accountable. This is where a lot of the most interesting work is happening, and it needs care.

• AI agents with wallets and hard limits: An agent can pay for services, rebalance or buy on your behalf, but only inside rules a smart contract enforces: spending caps, allowed counterparties and human approval above a threshold. Example: A procurement agent reorders stock automatically, up to ₹50,000 a day. Anything above that waits for a person.
• Provenance and proof for AI output: Record when content, data or a model decision was created, by what, and that it has not been altered since. Useful for authenticity, audits and disputes. Example: A newsroom proves a photo or report existed unchanged at a given time and came from a given source.
• Tamper-evident logs of AI decisions: Keep a permanent, ordered record of what an AI system decided and why, for regulators, partners and your own review. Example: A lender records each credit decision and the inputs used, so any decision can be explained later.
• Marketplaces for data, models and compute: Let people contribute data, models or compute and be paid automatically, with licensing and usage rules enforced by contract. Example: A dataset of labelled medical images is licensed per use, and each contributor earns a share automatically.
• AI assistants for on-chain activity: Ask questions in plain language about wallets, treasuries and protocols, and get answers, alerts and summaries without reading raw transactions. Example: A DAO treasurer asks "what did we spend last month and on what?" and gets a clear answer with links to each transaction.
• Risk, fraud and anomaly detection: Models that watch transactions and contract activity for unusual behaviour, and can pause or flag before money moves. Example: Unusual withdrawal patterns trigger a hold and an alert to the team before funds leave.

We will also tell you when you do not need a blockchain. Many AI products are better without one.

Networks and tools

We recommend the network that fits your users, fees and ecosystem. Typical choices:

Networks: Ethereum, Polygon, Base, Arbitrum, Optimism, BNB Chain, Solana, Avalanche, Private and consortium chains.

Tools: Solidity, Rust, Hardhat, Foundry, OpenZeppelin, ethers.js and viem, The Graph, IPFS, Chainlink oracles, Safe multisig.

How contracts are kept safe

Smart contracts handle money and cannot easily be fixed once live, so safety work comes before launch, not after.

• Threat modelling first We list how the system could be attacked before writing the code.
• Small, well-tested contracts Less code, standard audited building blocks, and thorough automated tests.
• Testnet before mainnet Everything runs on a test network with realistic scenarios before real funds are involved.
• Independent audit For anything that holds value we recommend an independent audit. It is a separate cost, and we help you prepare for it.
• Controls that limit damage Multisig ownership, pause switches, rate limits and careful upgrade paths where they make sense.
• Monitoring after launch Alerts for unusual activity and a plan for what to do if something goes wrong.

No software is risk free, and we do not promise that a contract is unbreakable. We reduce risk and tell you honestly what remains.

How a blockchain project runs

1. Discovery and feasibility We learn the goal, the users and the constraints, and tell you whether a blockchain is the right tool. You get: A written feasibility note.
2. Architecture and specification Network choice, contract design, token rules where relevant, security approach and a fixed scope with a quote. You get: Spec and quote in writing.
3. Build on testnet Contracts, interface and backend built in stages, with you trying each stage on a test network. You get: A working test version.
4. Review and audit Internal review, test coverage report, and the independent audit where it applies. You get: Review and audit report.
5. Launch Deployment to the live network, key handover and a launch checklist. You get: Live contracts you control.
6. Monitor and maintain Alerts, upgrades, fixes and support once real users depend on it. You get: Ongoing support, if you want it.

Rules differ by country, and they change

Laws on tokens, securities, crypto assets, payments and taxes vary widely and keep moving. We build software, and we are not your lawyer. We ask for your legal advice early, work to your lawyer's brief, and will not help build anything designed to mislead people or evade the law.

Priced for what you are building

A token and a tokenised-asset platform are very different projects, so there is no honest single price. We give you a fixed written quote after scoping.

• How many contracts and how complex they are
• Networks and integrations involved
• Front end and backend scope
• Independent audit and testing depth
• Ongoing monitoring and support

Frequently asked questions

What is a smart contract?

A program that lives on a blockchain and runs exactly as written. It can hold and move assets, enforce rules and record outcomes, with no single party able to change the result behind the scenes.

Do I actually need a blockchain?

Often you do not. A blockchain makes sense when several parties who do not fully trust each other need a shared record, or when assets must be truly owned and transferable. If a normal database does the job, we will tell you, and save you money.

What can you build on a blockchain?

Tokens, NFTs and memberships, DeFi mechanisms, tokenised assets, supply chain tracking, loyalty systems, identity and credentials, DAOs, marketplaces, payments, and AI + blockchain systems.

How much does a blockchain project cost?

It depends on what you are building, so we give a fixed written quote after scoping. The main factors are how many contracts and how complex, the networks involved, the front end and backend, and the depth of testing and audit.

How long does it take?

A small proof of concept and a production platform are very different. We give you a realistic timeline in the written scope, and we do not promise dates before we understand the work.

Is the audit included in the quote?

We do internal review and testing as part of the build. An independent audit is a separate cost paid to the auditing firm, and we recommend it for anything that holds value. We tell you this up front.

Can smart contracts be hacked?

Poorly built ones can, and some well-known losses have come from simple mistakes. We reduce the risk with threat modelling, small tested contracts, testnet runs, audits and controls like pause switches. No one can promise zero risk, and we will not.

What happens if there is a bug after launch?

That is why upgrade paths, pause controls and monitoring are designed in from the start, where they are appropriate. We agree an incident plan with you before launch.

Who holds the keys?

You do. Ownership of contracts and funds is set up in your control, usually with a multisig, and we do not keep access we do not need.

What is AI + blockchain?

Using both together: AI agents that pay within on-chain limits, proof of where AI output came from, tamper-evident logs of AI decisions, marketplaces for data and models, and AI that explains on-chain activity.

Can an AI agent safely hold a wallet?

Only within strict limits. We design the wallet so the agent can act inside rules a contract enforces: spending caps, approved counterparties and human approval for larger amounts.

Is it legal?

It depends on what you build and where you operate. Rules on tokens, securities and payments differ by country and change often. We build software, not legal advice, and we work to your lawyer's brief.

Will you guarantee token value or returns?

No. We build software. We do not promise returns or price, and we will not help with anything designed to mislead people.

Who owns the code?

You do. We hand over the code, the contracts and the accounts when the work is done.
