What are crypto integrations?

Crypto and Web3 integrations are the process of connecting external blockchain services, API providers, and protocols (wallets, payment gateways, exchanges, DeFi modules, NFT platforms) to your website, product, or app. These integrations allow you to connect your traditional business logic with decentralized infrastructure, providing access to crypto functionality without the need to build your own blockchain backend. With Web3 integrations, you can:

• accept crypto payments and work with on/off-ramp services;
• authorize users via Web3 wallets (MetaMask, WalletConnect, TON Connect);
• interact with exchanges, DEXs, and NFT marketplaces;
• receive data on tokens, transactions and on-chain activity;
• Integrate KYC/AML verification and security tools.

💡 In 2025, almost every Web3 project uses at least 3–5 external crypto services—smart integration is essential.

Main areas of integration

CryptonisLabs covers the full range of Web3 integrations, connecting your products to the most popular crypto services, payment modules, exchanges, and protocols. We ensure stable API operation, data security, and maximum compatibility with your technical infrastructure.

Crypto Payments & Gateways

Integration with payment systems such as Cryptomus, NOWPayments, BitPay, Binance Pay, and other providers allows you to accept crypto payments, automate billing, create subscriptions, and process transactions in any cryptocurrency. We ensure the correct operation of webhooks, payment calculations, exchange rates, and secure data processing.

Wallets & Web3 Login

We integrate Web3 wallets such as MetaMask, WalletConnect, TON Connect, Phantom, and other solutions for authentication, digital signatures, and crypto payments. These integrations ensure secure Web3 logins, user action confirmation, and seamless interaction with blockchain networks.

NFT Marketplaces & APIs

We set up integrations with OpenSea, Rarible, Magic Eden, TON NFT, and custom NFT modules. This allows you to automatically create, display, transfer, and sell NFTs, as well as manage collections, metadata, and market data through a unified API.

DeFi & DEX Integrations

We integrate Uniswap, PancakeSwap, 1inch, Jupiter, and other DeFi services for swaps, liquidity pools, staking, trade routing, and price aggregation. You gain access to DeFi functionality directly within your product without having to write smart contracts from scratch.

CEX Exchange APIs

Integrations with Binance, OKX, WhiteBIT, KuCoin, Bybit, and other centralized exchanges allow you to manage orders, balances, trade history, wallets, and market data. We provide secure authorization via API keys, data protection, and stable interaction with the exchange infrastructure.

Additional integrations

In addition to standard integrations with payment providers, wallets, and exchanges, the CryptonisLabs team implements an expanded suite of Web3 integrations for projects of any scale—from small applications to high-load platforms.

1. Blockchain Node Infrastructure and Providers

Integration with external node providers allows your product to interact securely and reliably with blockchain networks without the need to maintain the infrastructure yourself. CryptonisLabs configures access to RPC, WebSocket, and REST endpoints, ensuring high-speed request processing and correct operation of on-chain data.

Possibilities of such integration:

• receiving data from transactions, blocks and smart contract events;
• sending transactions and managing wallets via RPC;
• listening to events and implementing real-time updates via WebSocket;
• On-chain analytics and NFT/Token data API (Moralis, Covalent, Alchemy)
• connection to different networks and their testnets (multi-chain);
• access to historical blockchain data;
• increasing the stability and fault tolerance of applications;
• automatic scaling of requests to nodes;
• reducing costs for the development and maintenance of our own infrastructure.

💡 This approach speeds up development, reduces infrastructure costs, and ensures stable operation of Web3 services even under high load.

Supported providers: Alchemy, Infura / Consensys, QuickNode, Chainstack, GetBlock, Nownodes, Moralis Nodes, Tatum, BlockPi, Ankr (if necessary, you can add other providers or specify specific networks: Ethereum, BNB, Polygon, Solana, TON, Tron, Avalanche, Arbitrum, Optimism, etc.)

2. Own blockchain infrastructure and nodes

For projects with increased requirements for speed, security, data privacy, and infrastructure control, CryptonisLabs deploys its own full nodes, archive nodes, and validator nodes for various blockchains. This approach ensures maximum independence from external providers, operational stability, and high throughput for processing large numbers of on-chain requests.

What does your own blockchain infrastructure provide?

• full control over data, logs and internal processes;
• minimal response delay and high speed of query execution;
• no restrictions on the number of requests (unlike external APIs);
• increased stability and independence from third-party services;
• the ability to customize node optimization for your product;
• support for large volumes of historical data (archive nodes);
• corporate system level security – closed networks, firewalls, private RPCs;
• providing one's own validators and participating in consensus (staking/delegation).

Types of nodes we deploy:

• Full Nodes – processing transactions, data, and interacting with the network in real time.
  Archive Nodes – full access to the entire blockchain history.
• Validator Nodes — participation in the blockchain, block generation, staking, and increasing trust.
• Private RPC Nodes are closed channels for mission-critical products.
• Load-balanced Node Clusters — load balancing for highly loaded services.

💡 This infrastructure is used when standard RPC providers are limited in speed, access, or privacy.

3. Fiat On/Off-Ramp

Integrations with Transak, MoonPay, Mercuryo, Ramp, Banxa, and Simplex allow users to purchase cryptocurrency with fiat and withdraw funds back. These solutions simplify onboarding, increase conversion, and create a convenient bridge between traditional and cryptocurrency payments.

4. KYC/AML Verification

We integrate identification and transaction monitoring systems: Sumsub, ShuftiPro, Veriff, Onfido, and Fractal ID. They provide identity verification, compliance, risk analysis, and adherence to international security requirements. They are used on exchanges, launchpad platforms, and investment projects to ensure regulatory compliance.

5. Blockchain Data & Analytics APIs

Integrations with Moralis, Covalent, Alchemy, Infura, QuickNode, and the Etherscan API provide access to on-chain data, smart contract events, balances, transactions, and other analytical metrics. We build user-friendly interfaces for working with large amounts of blockchain data.

6. Cross-Chain Bridges & Oracles

We integrate technologies for cross-chain interaction and data retrieval: Chainlink, LayerZero, Wormhole, Axelar, and Python Network. This allows for asset synchronization across different networks, price feeds, and the implementation of complex cross-chain scenarios. This integration enables the construction of multi-chain DApps, DeFi platforms, and GameFi applications.

7. Portfolio & Token Analytics

Integrations with the Zapper, Zerion, DeBank, and DefiLlama APIs enable analysis of tokens, balances, yields, user holdings, and market dynamics. These tools are suitable for trading platforms, analytics dashboards, and crypto wallets.

8. Telegram / TON Payments

We implement payments through Telegram Stars, TON Payments, and mini-apps with Web3 interaction. Suitable for bots, marketplaces, mini-games, and services operating within the Telegram ecosystem.
