Blockchain & Web3 Development Company in Bangalore

On-chain work in Bangalore prices off audit surface and regulatory wiring, not contract line count. The tiers run: a scoped smart-contract MVP at Bangalore rates (single-chain ERC-20 or ERC-721 token plus a minimal staking, vesting, or marketplace contract, with one external audit and a testnet deployment) over six to ten weeks, a production DeFi protocol (lending market in the Aave V3 pattern, AMM in the Uniswap V3 pattern, vault product in the ERC-4626 pattern) including formal verification, multi-firm audits, oracle hardening, an Immunefi bug bounty, and a Safe-multisig governance setup, or a full exchange or institutional custody build in the CoinSwitch or CoinDCX pattern, with INR on-ramp under PA-PG, full KYC and AML, FIU-IND STR and CTR wiring, Section 194S 1 percent TDS automation, hot and cold wallet architecture on Fireblocks or AWS Nitro Enclaves, and a 24x7 SOC-grade incident pipeline. Cross-chain bridge and Layer 2 rollup engagements price separately depending on prover compute. We give fixed-fee proposals in INR and USD.

Operating a Virtual Digital Asset (VDA) business in India is legal but heavily regulated. The Supreme Court's March 2020 ruling in Internet and Mobile Association of India v. RBI struck down the 2018 RBI banking ban, so VDA service providers can operate, but the RBI still strongly discourages bank participation, and several major banks restrict INR-VDA rails. VDA income is taxed at a flat 30 percent under the Finance Act 2022, no loss set-off is permitted, and a 1 percent TDS under Section 194S applies to every transfer above the threshold. The PMLA amendments of March 2023 brought VDA service providers (exchanges, wallet providers, custodians) under FIU-IND reporting, requiring STR and CTR filings and a designated Principal Officer. CERT-In Cyber Security Directions 2022 impose a five-year log-retention obligation on VASPs and a six-hour incident-reporting clock. The India Crypto Bill has been drafted in multiple forms but has not been enacted as of 2026, so the current regime is tax plus PMLA plus CERT-In plus residual RBI discretion. We scope your engagement against that real regime, not a wished-for one.

Yes, with the regulatory caveat that the INR rail itself runs through a Payment Aggregator or Payment Gateway that holds an RBI PA-PG licence (or partners with one). We architect the on-ramp and off-ramp in the CoinSwitch Kuber, CoinDCX, and Bitbns pattern: a regulated PA-PG handles the INR side, our custody and ledger layer handles the VDA side, KYC runs against Aadhaar e-KYC or DigiLocker with Video KYC where the partner is RBI-licensed, the PMLA Principal Officer pipeline files STR and CTR with FIU-IND on schedule, and the Section 194S 1 percent TDS deduction is automated against PAN with quarterly Form 26Q filings. We design the system so the company can present a clean compliance file to an FIU-IND inspector, an income-tax assessing officer, and the partner bank's compliance team without three different versions of the same data.

There is no universal answer, and any vendor giving one without scoping your case is selling rather than advising. Polygon PoS remains the lowest-friction default for Indian retail consumer flows given gas profile, Indian-origin protocol stewardship (Sandeep Nailwal and the broader Polygon Labs Bangalore-Mumbai team), tooling maturity, and the broadest Indian wallet and exchange support. Polygon zkEVM and the CDK rollup framework are attractive when long-term ZK security is a priority. Arbitrum One and Optimism offer the deepest DeFi liquidity if your protocol needs composability with Aave, Uniswap, GMX, Pendle, or Curve at scale. Base offers the cleanest consumer onboarding via Coinbase's embedded onramp, which matters if your user base includes US persons. We run a decision matrix in discovery against gas cost per transaction, finality guarantees, bridge security, wallet and exchange support in the Indian retail base, and your team's familiarity with the chosen toolchain.

We treat audits as a multi-pass programme rather than a single line item. Internal review starts with Slither, Mythril, Aderyn, and Semgrep static analysis from day one of contract development, Foundry invariant tests and Echidna fuzzing run continuously against critical state, and Certora or Halmos formal verification is scoped for any contract holding meaningful TVL. External audits are scheduled at minimum from two firms for any protocol expected to hold more than USD 1M in TVL, and we have working relationships with Trail of Bits, OpenZeppelin, Halborn, Spearbit, Quantstamp, ChainSecurity, Zellic, Cantina, and the Indian-origin auditors QuillAudits and Hashlock. Audit findings are tracked in a single review-board document open to investors. After audits, an Immunefi or Code4rena bug bounty runs at least 14 days before mainnet, with a tiered reward scale calibrated to TVL at risk. Post-launch, we maintain an on-call response rotation with pre-drafted CERT-In six-hour notification templates and a Safe-multisig emergency-pause path explicitly tested in a dry run.

Yes, where the client is a participating bank or a partner in the RBI CBDC pilot. The Digital Rupee (e-Rupee) Wholesale pilot launched in November 2022 and the Retail pilot in December 2022, with HDFC Bank, ICICI Bank, SBI, Yes Bank, IDFC First, Kotak, Union Bank, and other participants progressively onboarded. We have shipped CBDC wallet integrations and merchant acceptance flows under the participating-bank programmes, with explicit alignment to the RBI's programmable-money pilot constructs (purpose-bound payments, expiry-bound payments, multi-tier issuance). Non-participating-bank clients can either join the pilot through a participating-bank partnership or pre-position infrastructure to onboard once the pilot expands. We do not offer to white-label or simulate CBDC functionality outside the official pilot scope, because that would not pass an RBI inspection.

Section 194S of the Income Tax Act 1961, introduced in Finance Act 2022 and effective from 1 July 2022, requires a 1 percent TDS deduction at source on transfer of any Virtual Digital Asset where the consideration exceeds INR 10,000 (specified persons) or INR 50,000 (other categories) in a financial year. For an exchange, broker, or any platform that facilitates VDA transfers, the obligation to deduct, deposit, and report TDS falls on the platform. We build that into the matching engine and withdrawal pipeline directly: every transfer above the threshold automatically deducts 1 percent against the user's PAN, deposits TDS with the government within the statutory window, generates Form 16A certificates, and feeds quarterly Form 26Q filings. We also build an unmatched-PAN exception queue that the finance team can clear before quarter-close. The Bangalore Income Tax department has been progressively more granular in its scrutiny of VDA TDS, and CoinSwitch and CoinDCX have set the operational standard.

Yes. The International Financial Services Centres Authority (IFSCA) in GIFT City, Gandhinagar, has progressively issued frameworks relevant to digital assets, including the IFSCA Bullion Spot Delivery Framework, the IFSCA framework for the issuance and listing of securities tokens in 2024, and ongoing FinTech Sandbox cohorts. For Bangalore-headquartered teams pre-positioning RWA tokenisation (tokenised money-market funds, tokenised bonds, tokenised real estate, tokenised invoices), GIFT City is the natural regulated wrapper. We build the on-chain issuance layer on a permissioned Hyperledger Besu or Quorum chain or, where the issuer prefers public-chain settlement, on Polygon PoS or zkEVM with explicit operator-allowlist logic and KYC-gated transfers. The legal wrapper goes through GIFT City counsel, the technology and operational controls go through us, and the resulting filing pack is one your IFSCA sandbox sponsor can route into the regulator without three rewrites.
