Blockchain & Web3 Development Company in Hyderabad

Blockchain technology is fully legal in India. The Reserve Bank of India distinguishes sharply between blockchain (encouraged, with the RBI itself running the wholesale and retail e-rupee CBDC pilots since 2022) and private cryptocurrency (heavily taxed at 30 percent on gains under Section 115BBH of the Income Tax Act, 1 percent TDS on transfers above thresholds under Section 194S, no offset of losses against other income, and informal banking restrictions on crypto exchange settlement). Enterprise permissioned chains for supply chain, identity, and government use cases face essentially zero regulatory friction. Consumer token issuance to Indian retail is a different conversation and we will tell you in week one whether the model survives a regulator review.

Pharma provenance pilots ship on Hyperledger Fabric or Besu with batch-level lineage anchored from the manufacturing execution system (MES) through to wholesaler dispatch. For Covaxin-style vaccine programs we model the cold chain telemetry signing flow so a temperature excursion produces a tamper-evident on-chain attestation, integrate with the central GS1 SGTIN serialization standard required for U.S. DSCSA, and build verifier dashboards for CDSCO and state drug controller inspectors. For Dr Reddy's and Aurobindo API shipments destined for U.S. and EU customers we layer the provenance chain over the NMVS verification for EU and DSCSA verification router service flows so the chain serves the regulator filings, not a separate marketing artifact.

Yes. The RBI launched the wholesale e-rupee CBDC pilot in November 2022 and the retail e-rupee pilot in December 2022, with multiple state and bank participants. Telangana State Government has signaled interest in citizen-facing CBDC integration and runs T-Wallet as the existing citizen wallet baseline. We have built proof-of-concept integrations between W3C Verifiable Credentials issued by the Telangana ITE and C Department and CBDC payment rails on participating bank APIs, designed offline payment flows for retail CBDC under the RBI specification, and produced the MeitY-aligned security review the Telangana State Technology Services (TSTS) team needs before any pilot goes live.

DPDPA 2023 introduces a fundamental tension with public chains: the right to erasure under Section 12 cannot be straightforwardly served by an immutable ledger. We design around this by keeping personal data off-chain in DPDPA-compliant storage on AWS ap-south-2 with strict access controls and erasure workflows, anchoring only hashes or zero-knowledge proofs on chain, and using selective disclosure W3C Verifiable Credentials so the data principal controls disclosure scope. For permissioned chains we implement a redaction-capable design (Hyperledger Fabric private data collections, off-chain pointers) so a Data Protection Board of India order for deletion can actually be honoured. We document this in a DPDPA architecture memo for your DPO.

We scope and quote each pilot rather than publishing bands. A scoped permissioned chain pilot (Hyperledger Fabric 2.5 with three to five organisations, one or two chaincode modules, off-chain integration to an existing MES or ERP) is a twelve to twenty week engagement including DR planning and audit. A public chain consumer product (Polygon PoS smart contracts, indexer on The Graph, MPC wallet integration, frontend) is a ten to sixteen week engagement. Smart contract audit by our team plus an independent firm (we partner with audit firms for critical contracts) is scoped against contract complexity and surface, with the independent firm's fee billed through separately. CBDC and government pilots are scoped after a feasibility week with TSTS and ITE and C.

Yes. Audit scope includes static analysis with Slither and Mythril, fuzzing with Echidna and Foundry invariant tests, manual review against the SWC Registry and OpenZeppelin Defender exemplars, and formal verification with Certora Prover on contracts that hold significant value. Findings are reported on the CertiK and Trail of Bits severity model (critical, high, medium, low, informational) with proof-of-concept exploits where feasible. We have audited Polygon-deployed contracts for T-Hub cohort startups and a small set of pharma proof-of-concept chaincodes. Audit windows are three to eight weeks depending on lines of code and complexity, and we re-test after remediation at no additional charge if remediation lands within thirty days.

Pharma supply chain and government identity rarely benefit from the open-network composability that justifies a public chain's cost and regulatory exposure. A permissioned Hyperledger Fabric or Besu network gives controlled membership, fine-grained access via Membership Service Providers, fast deterministic finality with Raft or IBFT 2.0, and predictable cost in rupee operating budgets that the Telangana State Treasury or a CDSCO-regulated pharma can plan against. Public chains stay in scope only when you genuinely need open verification by external parties (an EU customs inspector validating a DSCSA hash, an open NFT credential verifier) and the consumer Web3 use case warrants the chain economics. We document the choice and the trade-off in a written architecture memo before code is written.

Section 115BBH of the Income Tax Act, which imposes a flat 30 percent tax on income from the transfer of Virtual Digital Assets (VDAs), applies to crypto-asset transfers, not to building or operating permissioned blockchain infrastructure. A pharma using Hyperledger Fabric for batch genealogy or a state government running a permissioned identity chain does not generate VDA income from running the chain. Where a project involves token issuance to Indian retail, the 30 percent VDA plus 1 percent TDS under Section 194S, plus the GST treatment of token sales as services, becomes a serious tax and accounting issue, and we route those projects through a chartered accountant or tax counsel before architecture work begins.
