Crypto exchange API integration
Real-time prices, order book and balance data are pulled from exchanges' REST and WebSocket APIs; rule-based automated trading, stop and take-profit orders are managed. API keys are stored encrypted on the server side with only the permissions required, and rate limits and connection drops are handled safely.
Detailed example: crypto trading API integration.
Trading and analysis platforms
Number One Trading is a platform used by around 300 traders, offering live charts, analysis sharing and signal tracking for BIST and crypto. Real-time data streaming, membership and permission management, notifications and reporting all run on the same infrastructure.
Web3 wallet and smart contract integration
Web and mobile apps get Web3 wallet connection, signed sign-in, token balance and transaction history reading, and interaction with existing smart contracts. In smart contract development, testnet verification and an independent security audit are planned as mandatory steps.

Frequently asked questions
What does a blockchain developer do?
Builds software that works with crypto exchanges, blockchain networks and smart contracts: API integration, automated trading, trading platforms, wallet connection and contract interaction.
Can you build an automated trading bot for a crypto exchange?
Yes; infrastructure can be built that places orders through the exchange's API based on defined rules, logs everything and enforces risk limits.
Will my API keys be safe?
Keys are created with only the required permissions (withdrawals disabled) and stored encrypted on the server side.
How is smart contract security ensured?
The contract is verified on a testnet, tested against known attack scenarios, and an independent security audit is recommended before mainnet deployment.
What does a crypto exchange developer do?
Builds a crypto exchange's order matching, wallet, KYC/AML and admin layers, or connects existing systems to exchange APIs.
What should I look for when working with a crypto exchange developer?
Look for live finance/trading references, their security approach (wallets, keys, withdrawal approval) and their ability to build record-keeping and reporting infrastructure compliant with SPK (Capital Markets Board of Turkey) and MASAK (Financial Crimes Investigation Board) obligations.
