Orca is ideal if:

Builds on Solana’s fast, low-fee network, making it a great fit if you want quick, cost-effective token swaps.
User-friendly interface and tools like “Magic Bar” and Fair Price Indicator simplify DeFi for both beginners and seasoned users.
Concentrated liquidity (Whirlpools) offers efficient yield-earning potential—ideal if you seek to provide liquidity with precision.

Kuna is ideal if:

Effortless Quick Buys – If you prefer rapid purchases without account creation, Kuna’s “5-click” system lets you buy Bitcoin, Ethereum, or Tether in around 30 seconds directly to your wallet.
Straightforward and Friendly UI – Kuna offers a clean, intuitive interface (web and mobile) that’s especially suitable for newcomers and those who value simplicity and smooth navigation.
Regional Fiat Flexibility – If you're in supported areas, Kuna enables seamless fiat-to-crypto trades using local methods in UAH, USD, or RUB, plus tools like cash codes—making funding your trades frictionless.

Orca isn’t ideal if:

Limited solely to Solana’s ecosystem—which may not suit users looking to trade assets across other blockchains.
Lacks advanced trading tools and detailed charting, making it less appealing for those who rely on technical analysis.
Concentrated liquidity (Whirlpools) introduces increased risk of impermanent loss for liquidity providers.

Kuna isn’t ideal if:

Limited Asset Variety – If you're looking to trade a wide range of cryptocurrencies or exotic altcoins, Kuna offers only a modest selection that may feel restrictive.
Basic Trading Tools Only – For those seeking advanced charting, technical indicators, or professional-grade trading features, Kuna’s platform remains quite simplistic.
No PayPal or Wallet Options – If you prefer funding your account with PayPal, Skrill, or Neteller, or need live chat or phone support, you’ll find those options aren’t available here.

Fees & Total Costs

Spot Maker/Take

Orca doesn’t use traditional maker/taker models—spot trading occurs through liquidity pools structured via Automated Market Maker (AMM) mechanics, where pool creators set fixed or adaptive fee tiers (ranging roughly from 0.01% to 2%) that apply to all trades, and those fees are shared between liquidity providers, the protocol treasury, and a climate fund.

Kuna applies a flat 0.25 % trading fee for both makers and takers, without tiered volumes—though holding at least 100 KUN tokens grants VIP status, which waives maker fees entirely.

Futures/Derivatives

Orca is strictly a decentralized AMM-based spot platform on Solana and does not offer any futures or derivatives trading, meaning there are no maker/taker or funding fees to consider.

Kuna does not offer futures or other derivative trading instruments; therefore, there are no associated maker, taker, or funding fees.

Average Spreads on Liquid Pairs

Because Orca routes trades through concentrated liquidity pools (Whirlpools) via its smart router, traders usually benefit from highly efficient execution and minimized slippage; though exact spreads fluctuate dynamically, these liquid pairs consistently enjoy tight pricing thanks to deep, targeted liquidity.

Kuna does not publicly disclose spread data, and their simplified fee model suggests minimal hidden spread, though precise average figures for these pairs are not available.

Fiat Deposits & Withdrawals

Orca operates entirely on-chain without direct fiat support—it doesn’t accept or process fiat deposits or withdrawals, meaning no time delays or fees, but you’ll need to convert external fiat to crypto before interacting with the platform.

Fiat deposits are accepted (e.g., via credit card for Ukrainian-issued Visa/Mastercard or via methods like Perfect Money, Payeer, Advanced Cash, or Kuna Code), with variable fees depending on the method—withdrawals mirror those deposit options, again with method-dependent fees and typical processing within short timeframes.

On-chain Withdrawals

Orca doesn’t handle withdrawals across multiple blockchains—it functions solely on Solana, so on-chain fees consist only of Solana network transaction costs (typically a tiny, fixed amount of SOL), rather than dynamic variable fees across different networks.

Crypto withdrawal fees are based on asset and network; for example, withdrawing BTC incurs a fixed fee of approximately 0.0005 BTC. Other assets like ETH or TRX may have different dynamic fees, though Kuna doesn’t specify those publicly across all networks.

Hidden Costs

Orca avoids most hidden fees—there are no inactivity penalties or express KYC charges, and currency conversion only incurs standard swap route costs; the main ongoing cost is network transaction fees and whichever pool fees apply when trading.

There’s no explicit information about inactivity fees or express KYC charges; however, currency conversion may incur a flat percent fee embedded in the exchange rate, depending on your selected method.

Real-World Cost Example: “€500 BTC

Since Orca doesn’t support fiat on-ramps or BTC trading directly, a real-world purchase of €500 worth of BTC would involve using a separate service to convert euros to a Solana-compatible asset (e.g., USDC), then swapping via Orca to your target token—so total cost includes external fiat conversion spread, Orca’s pool fee tier (deducted from the input token), and the minimal Solana transaction fee.

Buying €500 worth of BTC would incur the standard 0.25 % trading fee and any minor spread embedded by the platform, plus the fixed withdrawal cost of ~0.0005 BTC when sending the funds on-chain—exact totals depend on BTC’s live price at the time.

Crypto Offering & Trading Features

Number of Coins & Pairs

Orca supports approximately 490 tradable coins and over 1,300 trading pairs, with the most active including SOL/USDC, SOL/STSOL, and SOL/MSOL based on volume.

Kuna lists approximately 22 to 40 cryptocurrencies and supports around 40 trading pairs, with the most active ones being BTC/UAH, ETH/BTC, ZEC/UAH, DAI/UAH, ZEC/USDT, KUN/USDT, BTC/USDC, and ETH/UAH.

Product Range

Orca focuses on spot swapping and liquidity provision—there’s no margin, derivatives, options, ETFs, loans, copy-trading, grid bots, or automatic DCA. It does reward LPs and enables staking of liquidity positions.

Kuna’s product suite is straightforward—spot trading only (crypto–crypto and crypto–fiat), no margin, derivatives, ETFs, lending, copy trading, grid bots, automatic DCA, or options; however, it does offer staking rewards through holding certain assets.

Liquidity

Orca handles hundreds of millions in daily volume—CoinGecko reports about $440–$540 million 24h across the platform, with deep liquidity especially in major pairs like SOL/USDC.

Kuna’s 24-hour volume is modest (several million USD equivalent), with BTC/USDT and ETH markets showing some activity; however, order-book depth is not publicly detailed, suggesting liquidity is appropriate for medium-sized trades but not high-frequency institutional-level operations.

Tools

Orca offers core AMM functionality—no limit, stop, OCO orders or alerts—though it includes handy UI features like the “Magic Bar” and Fair Price Indicator, and there’s SDK, developer APIs (TypeScript), and native Solana wallet integration.

Kuna supports basic order types like limit, market, and stop orders, features standard trading charts (not TradingView-native), and provides API access; it doesn’t offer advanced charting tools, OCO orders, price alerts, or built-in TradingView integration.

Geographic Restrictions by Product

Orca does not officially restrict any regions—however, users are advised not to access the platform if local laws deem it prohibited.

While spot trading is broadly available, Kuna does not provide derivatives or advanced products in any region, and its services are restricted for U.S. users; features like staking may also be limited depending on local regulations.

Innovation

Orca enables permissionless pool launches (via token-creation tools), supports concentrated liquidity with Whirlpools, and offers Double-Dip pools (earning dual rewards)—but it doesn’t include launchpads, launchpools, or separate flexible vs locked earn options.

Kuna’s innovation footprint includes unique tools like Kuna Code (transfer via code), Kuna Pay (payment processing), and browser extensions from the community, but it currently lacks features such as a launchpad, launchpool, or differentiated flexible vs locked earning programs.

Security, Regulation & Custody

Operating Entity & Jurisdiction

Orca is a decentralized, non-custodial protocol built on Solana with no central operating company handling custody; governance and UI are supported by an autonomous protocol structure, not a traditional corporate entity.

Kuna was founded in 2014 in Ukraine and maintained operations through regional entities—including those in the UK and Lithuania—but as of March 2025, the platform has fully ceased operations and is no longer active.

Licenses/Registration

Orca does not hold industry-standard exchange licenses like VASP or MiCA, given its decentralized architecture—there is no regulatory registration as it doesn’t engage in fiat transactions or centralized trading.

Kuna did not hold formal VASP licenses under European frameworks like MiCA, nor did it register under equivalent regimes; current regulatory programs such as those in the Cayman Islands or EU never applied to Kuna due to its closure prior to implementation of those licensing regimes.

Custody

The platform is fully non-custodial—users always retain control of their assets in their own wallets. Orca does not hold user funds, nor does it provide formal proof-of-reserves or cold storage backing, since liquidity is deposited by users in smart contracts.

Kuna undertook what it called “the largest Proof of Reserves in history” to demonstrate backing of user funds, though there is no evidence of third-party audits, formal PoR implementation, or specified cold storage reserve ratios.

Insurance & Protection Funds

Orca does not currently offer formal insurance or compensation funds for user losses; instead, it relies on strong security design and audit practices to safeguard the protocol and users’ liquidity.

No formal insurance products or customer protection funds were publicly offered or advertised by Kuna at any point during its operation.

Incident History

Orca has maintained a clean security record over its history—no hacks, fund losses, or regulatory sanctions have been recorded since its launch, and the team celebrates its continuous uptime and safety focus.

Kuna maintained a calm incident history, with no publicly documented hacks, platform outages, account freezes, or regulatory fines reported prior to its closure.

Risk Controls

Access is secured via users’ wallets; there are no built-in features like two-factor authentication, whitelists, or sub-account structures. Orca promotes a zero-trust design and encourages secure wallet use without centralized API permission controls.

Kuna offered basic security features such as two-factor authentication (2FA) and email confirmations, though advanced tools like withdrawal whitelists, anti-phishing measures, tiered sub-accounting, or granular API permission controls were not prominently supported.

Transparency

The protocol publishes regular security audits and adheres to standards like ISO 27001 and ISO 9001 for information security and quality management, offering clear documentation—but it does not offer monthly financial reports, formal SLAs, or public on-chain dashboards beyond smart contract visibility.

There were no monthly transparency reports, public audit statements, or disclosed service-level agreements. While the platform shared its initiative around reserves, ongoing financial transparency metrics or operational dashboards were not made available.

Deposits, Withdrawals, KYC & Support

Fiat Deposit Methods

Orca is fully on-chain and does not accept direct fiat deposits via bank transfer, cards, or e-wallets—users must first convert fiat to crypto outside the platform, typically via a centralized exchange or on-ramp service.

Fiat deposit options on Kuna include credit cards (limited to Ukrainian-issued Visa/MasterCard) and payment services like Advanced Cash, Perfect Money, Payeer, or Kuna Code; there’s no publicly stated minimum or maximum, and processing times vary—card payments can be nearly instant, while some transfer methods may take several minutes to days depending on method and region.

Supported Fiat Currencies & Conversion

KYC (Verification Levels)

Orca is a decentralized, non-custodial platform with no institutional KYC structure—there are no defined user levels (basic or advanced), identity checks, or trading limits based on KYC.

Kuna requires identity verification to unlock full functionality—basic account creation has limited access, and submitting documents (ID, proof of address) elevates you to a fully verified level, with no public breakdown of tiered access or trading limits, but verification is mandatory for fiat operations.

Withdrawals

Limits, Durations & Networks

Cryptocurrency withdrawals on Kuna support networks like ERC-20, TRC-20, BTC (native), and others; BTC withdrawals, for example, incur a 0.0005 BTC fee and typically process within 10 minutes after email and 2FA confirmation—limits are set internally and not publicly disclosed.

Customer Support

Users can open support tickets directly in the Orca UI, and also reach out via Discord or Telegram; requests are verified via wallet signature, and responses appear in the UI live ticket chat.

Kuna offers multilingual support via the help center and ticketing system (English, Ukrainian, Russian), with an extensive FAQ and tutorial base—while there’s no 24/7 live chat, support is accessible through email or tickets, and response times are generally prompt but unspecified.

Languages & Localization

Orca’s documentation and FAQs are available in multiple languages (including Chinese, Japanese, Korean, Vietnamese) though the platform UI doesn’t show fiat prices or localized fees in currencies like EUR; regulatory localization is up to the user.

The platform supports English (as well as Ukrainian and Russian), displays prices and fees in common fiat currencies like €/USD, and reflects some local regulatory positioning (e.g., awareness of Lithuanian VASP licensing), although it remains primarily headquartered in Ukraine.

App Quality & Stability

Orca is known for its smooth, highly responsive performance on Solana—it delivers a seamless experience, with low incidence of crashes and consistent updates, drawing praise for reliability in its V2 build.

Kuna offers a mobile app for both iOS and Android that integrates core features like deposits and withdrawals; while there’s no public data on crash rates or update frequency, documentation includes instructions for confirming withdrawals via the app—suggesting a maintained and functional experience.

Experience, Performance & Ecosystem

UX/UI

Orca’s interface is clean and intuitive for beginners, featuring playful visuals and straightforward navigation; it doesn’t currently provide separate “Lite” or “Pro” modes, so both newcomers and experienced users share the same streamlined experience.

Kuna’s design is widely praised for being intuitive and accessible to beginners, with no separate “Lite” or “Pro” modes—just a unified interface that blends simplicity with functionality to help new traders start quickly while still serving seasoned users.

Performance

Built on Solana, Orca delivers rapid execution with minimal latency, and gracefully handles market surges—its decentralized design avoids KYC queues and centralized congestion even during intense volatility.

Users report that orders on Kuna process nearly instantly under normal conditions; while data on crashes during volatile markets or extended KYC backlogs is limited, the lightweight design and responsiveness suggest generally stable performance even under pressure.

Education

Orca offers multilingual FAQs and guided documentation—including Spanish resources—but does not yet include a dedicated academy, demo environment, or simulator for hands-on learning or live practice.

Kuna currently offers limited educational materials and lacks demo or simulator tools; content is primarily in English, Ukrainian, and Russian, with no dedicated academy or learning hub in Spanish available at this time.

Community

Orca maintains active, developer-friendly channels on Discord and Telegram, fostering a collaborative community; while referral programs aren’t a featured part of its offering, users benefit from strong ecosystem engagement.

Kuna fosters an active user community via its official Telegram and social media channels, alongside a generous affiliate/referral program (up to ~75% commission), though it doesn’t operate its own dedicated forums or Discord server.

Integrations

Orca provides robust integration via its high-level SDKs, enabling automated trading and infrastructure use, though it doesn’t yet offer built-in links to TradingView charts, external trading bots, or tax/accounting platforms.

The platform doesn’t natively integrate with TradingView or third-party trading bots; there are no built-in tax reporting or accounting tools, making it more suited to straightforward trading rather than advanced automation or reporting workflows.

Who Each One Is Best For

Orca is ideal for on-chain DeFi users rooted in Solana, developers seeking modular liquidity functionality, and traders who value fast, transparent swapping—while those needing advanced charting, fiat tools, or demo environments may find it less suitable.

Kuna shines for casual traders, especially in Eastern Europe, who want a no-frills, easy-to-navigate platform for basic spot trading in fiat and crypto—making it a solid fit for those seeking simplicity and regional accessibility rather than advanced trading features.
