Blockchain & Web3 Development Company in Jaipur

Chain work for Johari Bazaar exporters is priced by how much inventory goes on-chain and how heavily it is audited: a scoped Polygon-based provenance NFT pilot for a Johari Bazaar jewellery exporter, a full production system with on-chain inventory of 50,000 plus stones, dealer dashboards, retailer scan-and-verify mobile apps, and GIA or IGI API integration, or a Hyperledger Fabric consortium for Mahindra World City SEZ corporates. Scope drivers include smart-contract development, an external audit from CertiK or QuillAudits, a custodial wallet workflow for buyers, an IPFS metadata pipeline, node count, and integration depth. Token-design and tokenomics-only engagements are fixed-fee and never billed in tokens of the project we are advising.

Under the Finance Act 2022, Section 115BBH imposes a flat 30 percent tax on income from transfer of Virtual Digital Assets with no deduction for cost beyond acquisition, no loss set-off across other heads, and no carry-forward of crypto losses. Section 194S imposes a 1 percent TDS on transfer of VDAs above thresholds. For provenance NFTs that never trade as financial instruments and that represent a real-world asset (a stone, a fabric SKU, a hotel-night entitlement) the VDA classification is fact-dependent and your tax counsel should opine before launch. For tokens that are clearly utility or governance, the same. We coordinate with firms like Lakshmikumaran and Sridharan, Khaitan, or AZB Partners for opinions, and we structure smart contracts to keep transfer events logged for TDS computation if the platform itself is a custodial intermediary.

Yes, and it is our highest-volume Web3 product line. Each stone or finished piece mints to an ERC-721 with metadata that anchors to IPFS — high-resolution photography, inclusion maps, GIA or IGI certificate hash, cut and weight, and chain-of-custody log from cutter to wholesaler to retailer. The metadata never publishes buyer PII on-chain. We integrate with Hallmarking BIS schema for gold and silver mounts and use W3C Verifiable Credentials so GIA, IGI, and Gübelin can sign attestations without joining a chain themselves. Retailer-side, a scan-and-verify mobile app reads the QR or NFC tag and proves authenticity to a Tiffany or Cartier buyer in seconds. Solidity contracts are audited externally before mainnet deploy, and a Polygon PoS chain is typical so per-mint gas stays under INR 5.

Yes. Tokenised loyalty makes sense when more than one property and more than one merchant category (rooms, F and B, festival tickets like JLF, spa, retail at City Palace gift shops) need to share a unified points economy without custodial Web2 lock-in. We typically deploy on Polygon PoS with account-abstraction wallets via ERC-4337 (Biconomy or Particle Network) so guests at ITC Rajputana, Rambagh Palace, or Samode Haveli onboard with email or phone, not a seed phrase. Points are an ERC-20 with controlled mint authority and burn-on-redemption rules. Compliance reviews against India's Foreign Exchange Management Act apply when international guests redeem, and DPDP Act 2023 obligations cover the underlying CRM data. Settlement between properties happens off-chain through the existing GST e-invoicing framework.

Most enterprise problems do not need a blockchain, and our discovery phase explicitly asks this. If the use case has one trusted writer (a single retailer, a single bank, a single auditor), a Postgres database with row-level append-only audit logging and signed records is faster, cheaper, and simpler. Blockchain becomes credible when multiple parties without a shared trust authority need to write to the same ledger — Jaipur jewellery cutters, wholesalers, GIA, retailers, end buyers — or when an external auditor (Tiffany compliance, EU Conflict Minerals reporting) needs cryptographic proof that records were not tampered after capture. We will tell you which bucket your problem fits during discovery, and we have walked Mahindra World City SEZ clients away from Web3 builds when a permissioned database was the right answer.

Every contract we deploy to mainnet — Polygon PoS, Polygon zkEVM, Ethereum L1 — passes an external audit from CertiK, Halborn, QuillAudits, OpenZeppelin, or Trail of Bits before launch, with a published report and signature trail. Internally we run Slither static analysis, Foundry fuzz tests, Echidna property-based tests, and Tenderly simulation across mainnet forks before submission to the auditor. We model reentrancy, integer over and underflow, oracle manipulation, MEV sandwich exposure, signature replay, and access-control misconfiguration. Post-deploy we run OpenZeppelin Defender alerting, Forta agents, and a public bug-bounty programme on Immunefi for at least 90 days post-launch. Incident response is documented and aligned to CERT-In 6-hour reporting where the platform serves Indian users.

Polygon PoS is our default for consumer-facing provenance and loyalty because it is Indian-founded (Sandeep Nailwal, Jaynti Kanani, Anurag Arjun, originally Matic Network), settles in seconds, and gas costs land under INR 5 per transaction. Polygon zkEVM where higher security parity with Ethereum is needed. Ethereum mainnet where value transferred per transaction crosses tens of lakhs and L1 finality matters more than gas. Solana where consumer throughput at festival-ticket scale matters and the team can absorb a different toolchain. Hyperledger Fabric for permissioned enterprise consortia at Mahindra World City SEZ where no token economy exists and read access must be restricted. We avoid newer L1s without proven uptime and pick chains your auditor and your insurer have heard of.

Yes. Under PMLA notifications from March 2023, Virtual Digital Asset Service Providers (exchanges, custodians, transfer agents) are reporting entities and must register with the Financial Intelligence Unit India (FIU-IND), appoint a Principal Officer, file Suspicious Transaction Reports, run KYC under the RBI's Aadhaar-eKYC or video-KYC framework, and retain records for ten years. We do not provide legal services but coordinate with firms like Nishith Desai, Khaitan, or Cyril Amarchand to scope registration scope, and we build the technical layer — KYC vendor integration (IDfy, HyperVerge, Signzy), transaction monitoring rules (TM rules), and STR-export pipelines — to support compliance. Non-custodial provenance NFT projects that never touch user funds typically fall outside VDASP scope, but again, your counsel decides.
