Shark Exchange vs Delta Exchange — if you’ve been trading crypto derivatives in India in 2026, you’ve almost certainly encountered both names.
They occupy the same niche: INR-native crypto futures and options platforms built for Indian traders who want to speculate on cryptocurrency price movements without buying the underlying assets.
But they are not the same platform, and for an active derivatives trader, the differences matter a great deal.
This Shark Exchange vs Delta Exchange article started with a genuine personal dilemma: I was already using Delta Exchange and had heard Shark Exchange was offering significantly lower trading fees.
Before committing capital to a newer platform, I wanted to do a thorough side-by-side analysis. This article is the result of that research — a direct, honest Shark Exchange vs Delta Exchange comparison covering fees, leverage, available products, security, INR experience, app quality, and referral benefits.
Before we dive in: both platforms have active referral codes worth using. For Shark Exchange, use code RAD737 at sharkexchange.in/referral?code=RAD737
For Delta Exchange, use code DELTAEARN at delta.exchange/?code=DELTAEARN for a 10% trading fee discount for 6 months.
🦈 Shark Exchange Referral Code: RAD737 → sharkexchange.in/referral?code=RAD737 ⚡ Delta Exchange Referral Code: DELTAEARN → delta.exchange/?code=DELTAEARN — 10% off all fees for 6 months
Shark Exchange vs Delta Exchange: Quick Overview
Before going deep into the Shark Exchange vs Delta Exchange comparison, here’s the essential snapshot:
Shark Exchange is a newer Indian crypto derivatives platform operated by Lightningnodes Technologies Private Limited, headquartered in Ahmedabad. It is FIU-registered (REID VA00045558) and focused exclusively on crypto futures and options with INR settlement.
Its core positioning is India’s lowest-cost derivatives exchange — with a maker fee of 0.016% and taker fee of 0.040%, which are among the most competitive fee structures available to Indian crypto derivatives traders anywhere in 2026.
Delta Exchange is a more established crypto derivatives platform — the India instance operated by Excelium Technologies Private Limited, FIU-registered (REID VA00041101), founded in 2018 and serving Indian users since 2021.
Delta has built a strong brand around product depth — perpetual futures, fixed-maturity futures, European-style options, MOVE (volatility) contracts, spread contracts, Robo Strategies, and a testnet environment. Its fees are higher than Shark Exchange but it brings a more mature ecosystem.
The short version of this Shark Exchange vs Delta Exchange comparison: Shark Exchange wins on fees and leverage cap. Delta Exchange wins on product breadth, track record, and advanced trading products.
Read on for the full Shark Exchange vs Delta Exchange breakdown.
Shark Exchange vs Delta Exchange: Company Background & Credibility
Shark Exchange
Shark Exchange is a relatively new entrant in the Indian crypto derivatives space. It is operated by Lightningnodes Technologies Private Limited, registered in India with FIU-IND (REID VA00045558), and headquartered at 13th Floor, Gala Empire, Memnagar, Ahmedabad — a publicly disclosed physical address, which is a positive transparency signal.
Being newer means Shark Exchange has a shorter operational track record. It was still building its community and user base as of early 2026, with a growing Instagram following and an appearance as a Gold Partner at TokenIQ 2026 — a major crypto conference in Bengaluru. The platform is clearly gaining recognition in India’s derivatives trading community.
This Shark Exchange vs Delta Exchange credibility comparison must be honest: as a newer platform, Shark Exchange has not yet been tested through a prolonged bear market, a major liquidity crisis, or an extreme volatility event the way Delta Exchange has.
That’s not a disqualifier — all platforms start somewhere — but it’s a relevant data point for risk-conscious traders deciding where to hold funds.
Delta Exchange
Delta Exchange has been operating since 2018 — over seven years — and the India-focused instance has been running since 2021.
This Shark Exchange vs Delta Exchange contrast in track record is significant: Delta has processed Indian trader activity through multiple market cycles, regulatory changes, and platform evolution.
It has maintained operations without a major security incident or regulatory action.
Delta Exchange India is backed by institutional investors and has grown to serve a substantial user base of Indian derivatives traders.
Its registration at multiple events, its documented participation in the Indian fintech ecosystem, and its consistently updated product offerings (MOVE contracts, Robo Strategies, API access) all indicate a well-resourced, long-term operation.
Shark Exchange vs Delta Exchange: Products & Trading Instruments
This is where the Shark Exchange vs Delta Exchange comparison becomes most practically important for traders deciding which platform to use.
Shark Exchange — Products
Shark Exchange offers:
Perpetual Futures: Trade BTC, ETH, SOL, and other cryptocurrency pairs with no expiry date. Go long or short with up to 150x leverage. Settle directly in INR — no USDT conversion needed. INR deposits via IMPS are instant and free. INR withdrawals are also free and processed to your verified bank account.
Crypto Options: Shark Exchange has added options trading to its product lineup, with a maximum fee cap of 5% of the option premium. This positions Shark Exchange as a full-spectrum derivatives platform, not just a futures exchange.
Isolated Margin Mode: Manage risk per position with isolated margin — your overall account isn’t affected by the liquidation of one position.
Real-time Charts with Advanced Indicators: The trading interface includes advanced charting with technical indicators. One notable gap flagged by users: the mobile app currently does not show P&L on charts, though the web interface does.
Fee Rebate Programme: Shark Exchange runs a Monthly Fee Rebate Program — if you’re profitable for the month, you can earn back trading fees. This is a distinctive feature that directly rewards winning traders.
Delta Exchange — Products
Delta Exchange offers a significantly deeper product catalogue:
Perpetual Futures: BTC, ETH, SOL, XRP, DOGE, and 50+ altcoin pairs. Up to 100x leverage. INR-settled on the India platform.
Fixed Maturity Futures: Daily, weekly, and monthly expiry contracts — allowing traders to express views tied to specific date horizons without perpetual funding rate exposure.
European-Style Options: Call and put options on BTC and ETH with full live Greeks display (Delta, Gamma, Theta, Vega), real-time payoff simulation, daily/weekly/monthly expiries, and deep ITM to deep OTM strikes. This is Delta Exchange’s most significant exclusive product in the Indian market — no other major Indian derivatives platform offers retail crypto options at this sophistication level.
MOVE Contracts: Volatility straddle derivatives that profit when price moves significantly in either direction. Unique to Delta Exchange in the Indian retail derivatives market.
Spread Contracts: Relative value instruments for trading the price difference between two assets.
Robo Strategies: Pre-built algorithmic trading strategies including Top 20 Momentum and Large Cap AMM, allowing non-technical traders to deploy automated approaches.
Testnet / Demo Account: Practice with real market data and zero financial risk before going live.
Free API (DhanHQ): Full REST and WebSocket API access for algorithmic traders, with sub-50ms order latency.
The Shark Exchange vs Delta Exchange Product Verdict
If you trade perpetual futures exclusively, Shark Exchange and Delta Exchange both serve this use case — with Shark Exchange offering lower fees and higher leverage (150x vs 100x).
If you want options trading, MOVE contracts, spread contracts, Robo Strategies, or a testnet, Delta Exchange is the only choice. These products simply don’t exist on Shark Exchange at comparable depth.
Shark Exchange vs Delta Exchange: Fees — The Most Important Comparison
This is the heart of the Shark Exchange vs Delta Exchange decision for cost-conscious traders. Let me lay out the numbers clearly.
Shark Exchange Fees
| Fee Type | Rate |
|---|---|
| Maker Fee (Futures) | 0.016% |
| Taker Fee (Futures) | 0.040% |
| Options Fee Cap | 5% of option premium |
| INR Deposit (IMPS) | Free |
| INR Withdrawal | Free |
| GST on Fees | 18% |
| Liquidation Fee | Taker fee + Insurance clearance fee |
Shark Exchange’s 0.016% maker / 0.040% taker fee structure for futures is genuinely industry-leading. For context, the global industry average is approximately 0.024% maker / 0.053% taker.
Shark Exchange’s taker fee (0.040%) sits below even the global average — making it one of the cheapest perpetual futures platforms available to Indian traders.
Additionally, INR deposits and withdrawals are both free — no hidden fees on the way in or out.
The Monthly Fee Rebate Program adds another layer: profitable traders can recoup a portion of their fees based on monthly performance, further reducing effective trading costs.
Delta Exchange Fees
| Fee Type | Rate |
|---|---|
| Maker Fee (Futures) | 0.02% |
| Taker Fee (Futures) | 0.05% |
| Options Fee (Maker + Taker) | 0.03% |
| Options Fee Cap | 3.5% of option premium |
| INR Deposit | Free |
| INR Withdrawal | Standard bank transfer fee |
| GST on Fees | 18% |
Delta Exchange’s futures fees (0.02% maker / 0.05% taker) are competitive but noticeably higher than Shark Exchange. On a ₹10 lakh futures trade, Shark Exchange’s taker fee (₹400) vs Delta Exchange’s taker fee (₹500) represents a 25% cost saving — meaningful at scale.
For options, Delta Exchange’s 0.03% fee with a 3.5% premium cap is actually more structured and trader-friendly for options-heavy users, particularly for deep OTM trades.
Referral discount: New users on Delta Exchange who sign up via code DELTAEARN at delta.exchange/?code=DELTAEARN receive a 10% discount on all trading fees for 6 months — which partially narrows the fee gap with Shark Exchange.
Shark Exchange vs Delta Exchange Fees Verdict
Shark Exchange wins on futures fees decisively. 0.016% maker and 0.040% taker vs Delta’s 0.020% and 0.050% — plus free INR withdrawals and a Monthly Fee Rebate Programme. For high-volume futures traders, the savings compound significantly.
Shark Exchange vs Delta Exchange: Leverage
Shark Exchange: Up to 150x leverage on crypto futures.
Delta Exchange: Up to 100x leverage on select perpetual futures.
This Shark Exchange vs Delta Exchange leverage gap is significant for experienced traders who use high leverage systematically. Shark Exchange’s 150x cap offers 50% more maximum leverage than Delta Exchange.
However — and this is critical in any Shark Exchange vs Delta Exchange assessment — higher leverage is a double-edged instrument. While 150x expands the upside potential, it also means a 0.67% adverse move liquidates your position.
High leverage is a tool for disciplined, experienced risk managers, not a shortcut. Both platforms clearly state that crypto trading with leverage carries significant risk.
Shark Exchange vs Delta Exchange: INR Experience
Both platforms deliver fully INR-native experiences — and this is a foundational strength they share.
Shark Exchange: INR deposits via IMPS (instant), INR withdrawals directly to verified bank account. Withdrawals are processed within minutes during working hours. Both deposits and withdrawals are free. No USDT conversion at any stage.
Delta Exchange: INR deposits via UPI, IMPS, and NEFT (free). INR withdrawals to linked bank accounts with standard transfer fees. Your entire trading P&L is tracked in Indian Rupees. No USDT required.
In this Shark Exchange vs Delta Exchange INR comparison, Shark Exchange has a slight edge — zero withdrawal fees vs Delta’s standard bank transfer fee on INR withdrawals.
Shark Exchange vs Delta Exchange: Security
Shark Exchange Security
- FIU-IND Registered: REID VA00045558 — full AML/KYC compliance
- Bank-grade security: End-to-end data encryption
- 2FA: Two-factor authentication on all accounts
- Instant KYC: Aadhaar + PAN verification, typically completing in under 5 minutes
- Publicly disclosed office address: Ahmedabad, India
Honest note: As a newer platform, Shark Exchange’s security infrastructure has not been stress-tested at the scale or duration that Delta Exchange’s has. The FIU registration is a meaningful compliance signal, but a shorter track record means fewer data points on how the platform handles extreme market events.
Delta Exchange Security
- FIU-IND Registered: REID VA00041101 — full AML/KYC compliance
- Multi-signature cold wallet storage for the majority of user funds
- 2FA: Mandatory on all accounts
- 7+ year clean operational record: No major security breach or fund misappropriation since 2018
- Institutional-grade infrastructure verified through consistent product delivery
In this Shark Exchange vs Delta Exchange security section, Delta Exchange’s longer operational track record and documented security infrastructure give it a meaningful edge. Shark Exchange has the right credentials but has not yet had the opportunity to demonstrate equivalent resilience over time.
Shark Exchange vs Delta Exchange: App & Platform Experience
Shark Exchange App
Available on Android (Google Play) and iOS (App Store). The interface is clean and designed for speed — sub-50ms order execution is advertised, and users generally confirm fast transaction processing. Real-time charts with advanced indicators are available.
Known gap from user feedback: the mobile app does not currently show P&L on charts, though the web interface does.
Users have specifically requested drag-and-drop SL/TP placement on charts — a feature not yet implemented but flagged for development.
Delta Exchange App
Available on Android and iOS, plus a full web interface. The platform includes native TradingView integration for charting.
The web version is significantly more feature-complete than the mobile app, particularly for options chain viewing, Robo Strategy management, and testnet access.
Known weakness from user feedback: the Delta Exchange app has documented performance issues during extreme market volatility — lag, freezing, and occasional crashes during sharp market moves. This is the most persistent criticism from Delta Exchange’s user base.
Shark Exchange vs Delta Exchange App Verdict
Both apps have their limitations. Shark Exchange’s app is cleaner and faster but currently lacks P&L chart display and drag-to-place SL/TP.
Delta Exchange’s app has more features but crashes during high-volatility events. For active futures trading, both require use of the web platform for the best experience.

Shark Exchange vs Delta Exchange: Who Should Use Which?

- You want a testnet to practice before risking real money. Shark Exchange has no equivalent.
- Track record and operational maturity are a priority. Delta’s 7+ year history provides meaningful assurance.
- You’re an options trader — Delta Exchange’s European-style options with payoff simulation and live Greeks are the most sophisticated options product available to any Indian retail crypto trader.

Sign up at delta.exchange/?code=DELTAEARN with referral code DELTAEARN for 10% off all fees for 6 months.
Can You Use Both?
Yes — and many sophisticated Indian derivatives traders do. Use Shark Exchange for high-volume perpetual futures trading where the 0.016% maker fee maximises cost efficiency.
Use Delta Exchange for options strategies, MOVE contracts, and complex multi-leg trades where product depth outweighs marginal fee differences. This Shark Exchange vs Delta Exchange duality actually makes practical sense for active traders who want the best of both platforms.
