In early 2025, Reliance’s Web3 initiative took a major leap forward by partnering with Polygon Labs, one of the leading Ethereum Layer-2 scaling solutions. This collaboration underpins JioCoin—an ERC-20 reward token—on Polygon PoS, ensuring lightning-fast transactions (<2 sec), minimal fees (<₹0.05), and a roadmap for DeFi integrations.
Background & Strategic Rationale
| Driver | Reliance (Jio) | Polygon Labs |
|---|---|---|
| Scale & Adoption | 500 M+ digital users across Jio apps | 200 M+ monthly active users on Polygon |
| Cost Efficiency | Micro-rewards demand sub-₹0.05 fees | Average gas ≈0.005 MATIC (~₹0.02) |
| Throughput | 50 M daily transactions envisioned | 7,000+ TPS |
| Ecosystem Synergy | In-app token rewards, DeFi future | Robust DeFi, NFT, gaming dApps |
| Regulatory Compliance | Aadhaar eKYC, loyalty-token classification | Permissioned bridge design, audit support |
- User Base Alignment: Jio’s massive user footprint needed a scalable chain. Polygon’s existing millions of active wallets offered a proven environment.
- Cost Imperative: JioCoin micro-transactions—rewards of 1–30 Coins—required near-zero fees. Polygon’s PoS delivered sub-penny costs, unlike Ethereum L1.
- Technical Roadmap: Early Polygon PoS integration paved the way for zkEVM bridge, unlocking Ethereum-level security and interoperability.
- Business Objectives: Reliance aimed to leverage Polygon’s DeFi ecosystem—liquidity pools, staking, NFT minting—fast-tracking JioCoin’s evolution.
Pro Tip: Partnerships at blockchain scale succeed when both parties align on users, technology, and regulatory posture—Jio and Polygon exemplify this synergy.
Technical Integration: Polygon PoS & zkEVM
Polygon PoS Layer
| Attribute | Specification |
|---|---|
| Consensus | Proof-of-Stake with 100+ validators |
| Finality | ~2 seconds |
| Gas Fees | ~0.0005 MATIC (₹0.02) |
| Security Anchor | Periodic checkpoints on Ethereum mainnet |
| Smart Contract Compatibility | Full EVM-compatible |
- Deployment: JioCoin contracts (
mint(),burn(),transfer()) deployed to Polygon PoS by Q1 2025. - Validator Network: Polygon’s decentralized validator set secures all JioCoin reward mints, burns (10 % on redemption), and transfers.
zkEVM Bridge Planning
| Feature | Benefit |
|---|---|
| Zero-Knowledge Proofs | Verifiable state transitions with minimal data |
| EVM-Equivalence | Run existing Ethereum smart contracts unchanged |
| Security | Ethereum mainnet finality & fraud proofs |
| Gas Efficiency | Batch proofs reduce cost per transaction |
| Interoperability | Seamless cross-chain JIO transfers to L2s/L1 |
- Timeline: Alpha bridge for 10 k testers launched April 2025; full public zkEVM slated Q3 2025.
- Integration Steps:
- Proof Generation: JioSphere constructs zk-SNARK proof of Polygon state.
- Proof Verification: Ethereum L1 smart contract verifies.
- Mint on Ethereum L2: Equivalent JIO tokens minted on zkEVM chain.

Smart-Contract Deployment & Audits
| Contract | Audit Provider | Key Findings |
|---|---|---|
| JioCoin ERC-20 | CertiK | No critical, minor overflow checks added |
| Staking v1.0 | Least Authority | Added reentrancy guards, updated allowance |
| Bridge Alpha | PeckShield | Verified proof validation, multisig config |
- Multi-Sig Ownership: 2-of-3 for mint/burn; 3-of-5 for bridge validations.
- Pausable Controls: All critical contracts include
pause(), requiring multi-sig to resume. - Source Verification: Contracts verified on PolygonScan and Etherscan for transparency.
Performance Metrics & User Experience
| Metric | JioSphere (Jan–Apr 2025) | Polygon Baseline |
|---|---|---|
| Daily Reward Mints | 20 M | N/A |
| Average Confirmation | 1.5 s | ~2 s |
| Peak TPS (Reward Window) | 5 k+ | 7 k+ |
| Avg. Fee per Redemption | ₹0.01 | ₹0.02 |
| UX Delays | <2 s | <3 s |
- Seamless UX: Users experience immediate balance updates (<2 sec) when redeeming JioCoins in JioSphere and JioPay.
- Scalability Tests: During peak festive campaigns, Polygon PoS handled 100 tps sustained for 2 hrs without congestion.
- Mobile Optimization: JioSphere’s in-app web3 provider caches signed transactions to reduce latency on Android and iOS.
Pro Tip: Performance metrics should align with user expectations—sub-three-second transaction times drive higher engagement and reward redemption rates.
Security & Compliance Synergies
| Aspect | Joint Measures |
|---|---|
| KYC/AML | Polygon KYC++ framework for major DEXs; Jio’s eKYC |
| Regulatory Reporting | On-chain data exported for audit; compliance dashboards |
| Data Privacy | Minimal PII on-chain; off-chain datastores encrypted |
| Incident Response | Shared security operations center (SOC) integration |
- KYC Integration: Future DEX/CEX listings will leverage Jio’s Aadhaar-eKYC to speed user onboarding on Polygon DEXs.
- Regulatory Alignment: Both parties adhere to India’s draft crypto rules—reward tokens classification—simplifying listings and AML processes.
- SOC Collaboration: Jio and Polygon SOC teams share threat intel and coordinate on bug bounty escalations.
