Custom Blockchain Solutions
Blockchain where it earns its place
We build smart contracts, tokens and the systems around them for cases where several parties must verify the same record — and we say so when a plain database would do the job.
Talk to us about your projectWhen blockchain is the right answer
Blockchain earns its place when several parties who do not fully trust each other need to read and write the same record: supply-chain custody, cross-border settlement, ownership and title, tokenised assets. It also earns it when a tamper-evident audit trail matters more than raw speed. One organisation with one dataset is better served by a Postgres database.
Most of the work is not the chain. It is the wallet flows, the admin tooling, the API layer your existing systems call, and the tests that prove a contract behaves when someone sends it something unexpected. Contracts are short. Getting them right, and keeping the rest of the product usable, is the job.
Capabilities
What we build
A tokenised asset and a supply-chain ledger are different problems, and on both of them the chain is the smallest part of the work.
-
Smart contract development
Business rules written as contracts: escrow release, revenue splits, vesting schedules and role permissions — with a unit test per branch, including the ones that revert.
-
Security review and audit
Static analysis, exhaustive unit and integration tests, testnet runs with real user flows, and a third-party audit before a contract holds customer funds.
-
Tokenisation
Standard on-chain token formats for assets, rewards or internal credits, with distribution, vesting and liquidity set up. Or your existing stablecoin, if launching a new asset helps nobody.
-
Chain selection
Public chain when transparency or token economics matter, permissioned chain when privacy and throughput matter more. We write down the reasoning and the gas cost per transaction.
-
Wallets and dApp interface
Wallet connection, signing and transaction states, including what the screen honestly shows a user while their transaction is still pending.
-
Backend, APIs and indexing
An indexed read layer so your app queries a normal database instead of the chain, plus webhooks that fire when a contract emits an event.
-
Enterprise integration
Middleware that lets an existing ERP, CRM or finance system read from and write to the chain without your team learning a new stack.
-
Identity and access control
Role-based permissions, allowlists and key management, so the address that can pause a contract is not the one running daily operations.
-
Monitoring after launch
Dashboards for transaction volume, failed calls and wallet activity, with alerting on the specific contract events that mean something has gone wrong.
What you get
What you own at the end
Everything below is handed over, including the audit findings we chose not to fix.
- Deployed contracts
- Audited contracts on mainnet
- Source code, deployment addresses, source verified on the block explorer, and the audit report with every finding and what we did about it, including the ones we accepted and why.
- The application
- dApp, admin panel and APIs
- The interface your users see and the panel your team operates it with, deployed to your infrastructure or ours, with the repository and CI pipeline handed over.
- Test evidence
- Test suite and testnet history
- Every payout, transfer and permission scenario as a runnable test, plus the testnet transactions behind them, so a future change can be checked against behaviour you already signed off.
- Operating notes
- Runbook and cost model
- What was built, which keys control what, the monthly cost to run including gas, and what to do on the day a contract has to be paused or upgraded.
How we work
From idea to mainnet
Durations below are typical for a first mainnet release. Contracts are quick to write and expensive to get wrong, so most of the effort sits before deployment.
-
Fit check
1–2 weeksWe work out whether this needs a chain at all, which parties sign what, and where the trust problem actually sits. Some projects stop here, and that is a fine outcome.
-
Contract design
2–3 weeksState, roles, events and failure paths written down before any code, because a deployed contract is costly to change and public the whole time you are changing it.
-
Build and audit
6–12 weeksContracts, dApp, admin panel and integrations built together, then static analysis, testnet runs with real flows, and a third-party audit before anything touches mainnet.
-
Launch and run
OngoingMainnet deployment, monitoring and the upgrade path we agreed. Gas costs and usage patterns look different in the wild, so the early weeks are tuning.
Is this the right service for you?
Worth two minutes before you get in touch. It saves both of us a call.
A good fit if…
- Several parties need to verify the same record without trusting one another
- You need an audit trail that nobody, including you, can rewrite
- You are issuing a token, or tokenising an asset with real ownership
- You want a chain layer added to software you already run
Probably not, if…
- One organisation, one dataset — our Web & SaaS Platform Development service fits better
- You want an MLM compensation plan on-chain — see Blockchain MLM Software
- You only want to accept crypto at checkout — that is Custom Payment Gateway Integration
- The point is the announcement, with no record anyone outside needs to verify
Frequently Asked
Questions
Common questions about custom blockchain projects.
When multiple parties who don't fully trust each other need to share and verify data (supply chain, cross-border payments, title records, tokenized assets), or when tamper-proof audit trails matter more than raw speed. If you're a single organization with a centralized dataset, a traditional database is almost always the right call.
Both. Public chains (Ethereum, Polygon, BSC, Solana) when transparency or token economics matter. Private/permissioned chains (Hyperledger Fabric, Quorum) when enterprise compliance, privacy, or throughput matter more than decentralization. We pick per use case.
Smart-contract design and development, security audits, token or NFT issuance, wallet integration (MetaMask, WalletConnect), backend + API layer, admin dashboards, user-facing dApp UI, and post-launch monitoring. For enterprise projects, add identity, access control, and integration with existing ERP/CRM systems.
Our process: follow battle-tested patterns (OpenZeppelin), write exhaustive unit and integration tests, run static analysis (Slither, Mythril), deploy to testnet for real-user simulation, and — for production contracts holding funds — commission a third-party audit (CertiK, Hacken, OpenZeppelin, or similar) before mainnet launch.
A basic smart-contract + dApp (tokenization, simple DeFi logic) starts around ₹5L–₹12L (\$6k–\$15k). Production-grade platforms with audited contracts, backend integration, admin tools, and mobile support run ₹20L–₹80L+ depending on complexity. See our blockchain development cost guide for detailed tiers.
Yes. Most clients don't want a rip-and-replace — they want a blockchain layer bolted onto an existing ERP, supply-chain platform, or financial system. We build APIs and middleware that let your current software write to and read from blockchain without your team needing to learn a new stack.
