Blockchain & Web3 Development Company in Delhi

Procurement route decides more of a Delhi-NCR blockchain budget than the choice of chain does. A proof-of-concept for a PSU or central government department with Hyperledger Fabric or Besu, a two-organisation consortium, and GFR-2017 procurement documentation is an eight to fourteen week engagement. A production consortium chain at Indian Oil or NTPC scale adds multi-organisation governance, regulator observer nodes, CERT-In incident hooks, and integration with existing SAP S/4HANA or Oracle ERP over six to twelve months. A Polygon or Arbitrum public-chain tokenisation or loyalty platform for a Gurugram fintech captive is driven by smart contract complexity and audit depth. An Aadhaar-linked verifiable credential platform aligned to ABDM and DigiLocker sits in similar territory. We quote fixed-fee per phase in INR, and proposals include the Slither, Mythril, Echidna, and Certora verification budget plus a third-party audit budget (CertiK, OpenZeppelin, Trail of Bits, or QuillAudits) for mainnet deployments.

General Financial Rules 2017 (GFR-2017) Rule 173 governs IT services procurement for central government departments and PSUs. GeM (Government e-Marketplace) listing covers the smaller-ticket procurement, while larger blockchain engagements typically go through limited or open tender with technical-and-commercial bid evaluation under Rule 173. We support clients with pre-bid clarification responses, technical bid documentation aligned to PSU evaluation matrices, the EMD and PBG financial requirements, and post-award milestone-linked invoicing with the documentation auditable by the CAG. MeitY Empanelment for cloud and security services is available where the engagement scope requires it. For Maharatna and Navratna PSU clients we coordinate with their internal CISO, CTO, and CFO offices on the CERT-In, DPDP, and GFR-2017 sign-off chain in parallel rather than serially.

Yes, with regulatory care. Aadhaar authentication for KYC purposes runs through UIDAI under the Aadhaar Act 2016 with AUA (Authentication User Agency) and KUA (Know-your-customer User Agency) licensing where applicable; only specific regulated entities can do direct Aadhaar authentication. For most verifiable credential use cases we route through DigiLocker's Issued Documents APIs and the Pulled Documents flow, which are open to a broader set of integrators and avoid the AUA/KUA licensing overhead. ABDM (Ayushman Bharat Digital Mission) APIs from the National Health Authority cover health records under the ABDM Sandbox and production tracks. We use W3C Verifiable Credentials and DIDs as the foundational standard with Hyperledger Aries-Indy or AnonCreds where revocation registries matter, and we map every deployment against DPDP Act 2023 personal data obligations including consent capture in 22 scheduled Indian languages.

CERT-In's April 2022 directions apply to blockchain operators, exchanges, custodians, and tokenisation platforms exactly as they apply to any other IT system in India. Reportable categories include unauthorised access, smart-contract exploits, oracle manipulation, custodial key compromise, and DDoS against RPC endpoints. The 6-hour clock starts at noticing or being notified, and reports go to incident@cert-in.org.in with prescribed details. We bake the 6-hour notification into the operational runbook with pre-drafted CERT-In templates, an escalation tree covering smart-contract pause authority, custody key holders, exchange counterparty notifications, and your legal counsel. KYC and customer record retention obligations (5 years under the April 2022 directions for VPN, cloud, VDA, and intermediary services) get documented in your data retention policy. DPDP Act 2023 personal data breach notification runs on a parallel track to the Data Protection Board with its own timelines.

Yes. Maruti Suzuki (India's largest car maker with manufacturing at Gurugram, Manesar, and Kharkhoda plus the Suzuki Motor Gujarat plant at Hansalpur) and Hero MotoCorp (the world's largest two-wheeler maker with plants at Dharuhera, Gurugram, Haridwar, Neemrana, Halol, and Chittoor) run multi-tier supplier networks with serialised parts (engines, transmissions, ECUs, batteries, EV-specific components under the FAME-II and PLI schemes) where blockchain-backed warranty-fraud detection and counterfeit-parts protection materially affect aftermarket margins. We deliver Hyperledger Fabric consortium chains with confidential channels per supplier tier, integration with SAP S/4HANA and Oracle ERP at OEM and Tier-1 supplier level, and GS1 SGTIN serialisation per the automotive aftermarket standards. For EV-specific battery passport requirements (relevant under the EU Battery Regulation 2023 for any Indian OEM exporting to the EU from 2027) we align to the same architecture pattern as our Arvind Mills DPP work.

Section 115BBH (effective April 2022) levies a flat 30 percent tax on income from transfer of virtual digital assets (VDAs) with no set-off of losses, and Section 194S levies 1 percent TDS on every VDA transfer above the threshold. The definition of VDA is broad and captures cryptocurrencies, NFTs, and most token transfers. For pure-utility tokens, governance tokens with no monetary expectation, and Hyperledger-based consortium tokens without market trading, the position is debatable; CBDT has issued no comprehensive carve-out yet. For tokenised securities under SEBI sandbox or IFSC tokenisation under IFSCA the treatment differs. Every Delhi-NCR engagement closes with a CA-signed tax position memo so the income-tax department and your auditors have a documented basis. Cross-border token movement intersects with FEMA and Liberalised Remittance Scheme limits, which is a separate analysis we run jointly with your CFO and legal counsel.

Every Solidity, Vyper, or Rust contract goes through a layered review: developer-level pair programming with checklist enforcement (Checks-Effects-Interactions pattern, reentrancy guards, overflow handling on Solidity less than 0.8 if applicable, oracle staleness, access control), static analysis with Slither and Mythril, fuzzing with Echidna and Foundry's invariant testing, manual review by a separate engineer not on the build team, and formal verification on critical clauses with Certora or Halmos. For high-value mainnet deployments we layer a third-party audit (CertiK, OpenZeppelin, Trail of Bits, or Indian boutiques QuillAudits and Hashlock) before launch. Post-deployment we deploy continuous monitoring through OpenZeppelin Defender, Forta, or Tenderly Web3 Actions, with multi-sig key custody on Fireblocks or BitGo plus tested emergency-pause procedures and a documented incident-response runbook the SOC can actually execute at 2 AM.

The Open Network for Digital Commerce (ONDC) is the MCA-promoted protocol for open commerce in India, headquartered in Delhi, with growing seller, buyer, and logistics participation. ONDC itself is not a blockchain but defines protocol specifications (Beckn-based) for catalog, order, fulfilment, and settlement flows. We have built buyer-app and seller-app integrations on ONDC and have scoped blockchain-anchored audit-trail and reconciliation layers on top of ONDC transactions for clients where payment-rail reconciliation and dispute-cycle reduction materially matter. UPI integration through PhonePe, Paytm, BHIM, or third-party PSPs sits in the same workflow. For Gurugram-Noida fintech captives we have shipped tokenised loyalty and merchant-incentive layers anchored on Polygon or Arbitrum that integrate cleanly with the ONDC merchant base.
