Heleket

Heleket is a cryptocurrency payment processing service designed for online merchants. It handles the complete payment lifecycle from customer checkout through to merchant wallet crediting, and separately offers virtual Visa cards that can be loaded with stablecoins for online spending.

How It Works

Merchants integrate Heleket through one of three paths: a JavaScript payment widget embedded in their site, a direct REST API for custom builds, or pre-built plugins for popular commerce platforms. When a customer pays, Heleket generates a unique receiving address for that transaction, monitors the relevant blockchain for confirmation, and credits the merchant's internal account. The merchant can then hold funds in the received asset, trigger automatic conversion to USDT or USDC to protect against price volatility, or schedule automatic withdrawals to an external wallet when a configurable balance threshold is met.

For businesses that need to disburse funds at scale, Heleket offers a mass payout feature that allows sending to multiple recipients in a single operation. A built-in converter handles asset swaps within the platform, and payment links provide a no-code option for merchants who do not require a full site integration.

Registration requires only an email address. No phone number or identity documents are needed at sign-up, though account moderation takes up to 24 hours before full access is granted.

Supported Cryptocurrencies

Heleket supports more than 20 digital assets, including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Tether (USDT on both ERC-20 and TRC-20 networks), USD Coin (USDC), Litecoin (LTC), Tron (TRX), Binance Coin (BNB), Dogecoin (DOGE), Toncoin (TON), Monero (XMR), Dash, Polygon (MATIC), Bitcoin Cash (BCH), Dai, and GRAM. The currencies page on the Heleket website is the authoritative list and is updated as new assets are added.

Solana Integration

SOL is a supported payment currency on Heleket. The platform highlights Solana throughput and low transaction costs as specific advantages for merchants: network fees run approximately $0.00025 per transaction, and Solana capacity to process thousands of transactions per second means payments register close to instantly. Heleket markets its Solana support specifically toward game developers, NFT projects, DeFi applications, and other businesses whose customers are active on the Solana network.

Virtual Cards

Heleket issues virtual Visa cards funded with USDT or USDC. To create a card a user needs a minimum account balance of $20; the card is issued with a $15 balance, making the effective issuance fee $5. Cards have a one-year validity period and are digital-only — card details are accessed through the Heleket dashboard. They cannot be linked to Apple Pay or Google Pay. Cards are usable at services including Netflix, Spotify, Google Ads, Facebook Ads, and Steam. Two-factor authentication is required on the account to access the virtual card feature.

CMS and Platform Integrations

Pre-built modules are available for WooCommerce, WHMCS, XenForo, OpenCart, and PrestaShop. These modules handle the payment flow without requiring custom API work. Merchants on other platforms can use the REST API directly with code examples provided in the documentation.

Fees and Pricing

Processing fees start from 0.4% on incoming payments. The platform states there are no setup fees, no connection fees, and no withdrawal fees. The company compares this favorably against traditional card acquiring, which typically runs 1.5% to 4% plus additional international transaction charges.

Scale and Reach

According to figures on the Heleket website, the platform processed $1.3 billion in payment volume in 2025, serves more than 100,000 active users, and supports merchants operating in over 190 countries.

Security and Compliance

Heleket implements two-factor authentication for account access and applies AML and CFT compliance policies that automatically flag suspicious transactions. The platform claims 99.99% historical uptime and a 99.9% success rate for automatic transaction recognition. No independent third-party security audits are publicly documented. Webhook testing tools are available to help merchants debug integrations before going live.

Team and Background

No information about Heleket founding date, company registration details, or team members is publicly disclosed. Support is available 24 hours a day via online chat, email, and Telegram. Each merchant is assigned a personal account manager for onboarding and ongoing technical questions. A referral program offers up to 30% commission on fees generated by referred merchants.

Ecosystem Fit

Heleket sits in the payment processing layer of the Solana ecosystem rather than in DeFi or infrastructure. Its relevance to Solana is as a crypto-to-merchant settlement layer: merchants who want to accept SOL payments without building custom blockchain integrations can use Heleket existing plugins and API. The platform auto-conversion feature means a merchant can accept SOL and immediately hold USDC without manual intervention, reducing exposure to SOL price movements while still serving Solana-native customers.
