Chainstack
Chainstack is a production-grade blockchain infrastructure provider delivering managed RPC nodes, archive data access, real-time streaming, and dedicated node infrastructure across 70+ blockchain protocols. Designed for teams building multi-chain applications, trading systems, analytics platforms, and AI agents that need reliable, high-performance blockchain connectivity without the overhead of running their own nodes, Chainstack serves developers ranging from solo builders on a free plan to enterprise trading desks on dedicated infrastructure. For Nigerian Web3 developers, DeFi teams, and blockchain startups, Chainstack provides the node access layer that is the foundation of every blockchain application.
Nigeria's growing blockchain developer community needs reliable, low-latency access to Ethereum, Solana, BNB Chain, Base, and other networks. Running your own blockchain node is impractical for most Nigerian startups — it requires significant cloud infrastructure costs, continuous maintenance, and weeks of initial chain synchronization. Chainstack eliminates all of that by providing managed, globally distributed nodes that Nigerian developers can start using in minutes with a free-tier API key.
Chainstack provides RPC (Remote Procedure Call) endpoints for reading and writing to supported blockchains including Ethereum, Solana, Bitcoin, Base, Arbitrum, Polygon, Avalanche, and 65+ more. Key capabilities include: full node RPC for current-state queries; archive node access for complete historical data going back to the genesis block; WebSocket subscriptions for real-time event listening; Yellowstone gRPC streaming for ultra-low-latency Solana data (blocks, transactions, account changes); advanced token and NFT APIs; and global routing that automatically directs requests to the nearest region for the lowest possible latency.
Archive node access is particularly valuable for Nigerian blockchain analytics companies and DeFi protocols that need historical data. A full node only stores the current blockchain state — it cannot answer questions about what an address's balance was six months ago. Archive nodes store every historical state, enabling queries like "what was the ETH balance of this address at block 15,000,000?" This historical data layer is essential for backtesting, analytics, and compliance workflows.
The Yellowstone gRPC streaming interface for Solana is a premium capability that enables sub-millisecond data delivery for Solana-specific events: new blocks, new transactions, account state changes, and program-specific events. For Nigerian DeFi trading systems and MEV (maximal extractable value) infrastructure that operate on Solana, this real-time streaming is critical for competitive execution.
Chainstack uses a Request Unit (RU) billing model rather than per-method pricing. Each API call consumes RUs from the monthly pool: full node requests cost 1 RU, archive requests cost 2 RU. This transparent billing means Nigerian developers always know exactly what their usage costs. The free Developer plan provides 3 million RUs per month with no credit card required — sufficient for building and testing most dApp features. Paid plans scale from Growth ($49/month, 20M RUs) through Pro ($199/month, 80M RUs), Business ($349/month, 140M RUs), and Enterprise ($990/month, 400M RUs with custom SLAs and dedicated infrastructure).
Nigerian blockchain teams building production-scale applications — exchanges, wallets, DeFi protocols, NFT platforms — benefit from Chainstack's globally distributed node network. Chainstack operates nodes across multiple cloud regions, and its global routing automatically connects each request to the nearest available node. This reduces latency for Nigerian developers and their end users compared to a single-region node provider. For latency-sensitive applications like trading bots and real-time price feeds, this geographic distribution matters.
Multi-chain support in a single platform is another key advantage. Rather than managing separate accounts and configurations across Alchemy (for Ethereum), Helius (for Solana), and other per-chain providers, Nigerian developers can manage all blockchain connectivity from Chainstack's unified dashboard. One account, one billing relationship, and one API key pattern across every supported chain simplifies developer operations for teams managing complex multi-chain infrastructure.
Authentication uses API keys generated in the Chainstack dashboard under Settings. Keys are embedded directly in the RPC endpoint URL for most protocols, or passed as a header for HTTP-based requests. WebSocket connections include the API key in the WebSocket URL. No geo-blocking has been reported for Nigerian users — Chainstack is a global infrastructure provider accessible from Nigeria without restrictions.
