1 Best APIs for Event Streaming (Chain Watch) in Nigeria

Blockdaemon is an enterprise blockchain infrastructure provider that offers the APIs, nodes, and custody tools powering the digital asset economy for regulated institutions and developers. Founded in 2017, Blockdaemon serves banks, asset managers, exchanges, fintechs, and Web3 developers who need production-grade blockchain infrastructure without the overhead of running their own nodes or managing validator keys. The company is ISO 27001, SOC 1 Type I, and SOC 2 Type II certified — making it one of the most compliance-ready blockchain infrastructure providers available. What the API Does The Blockdaemon API Suite comprises several products: (1) RPC API — low-latency JSON-RPC endpoints for reading and writing to supported blockchains including Ethereum, Solana, Cardano, NEAR, Sui, and TON among 12+ protocols; (2) Staking API — programmatically stake assets, manage validators, and retrieve staking rewards with compliance-ready reporting; (3) Wallet Transact (MPC Wallet API) — create and manage MPC (Multi-Party Computation) wallets for institutional key custody; (4) Chain Watch — real-time event streaming and blockchain data indexing for on-chain monitoring; (5) NFT API — metadata retrieval, ownership queries, and transfer history for NFTs across chains. How Developers Use It Developers sign up at app.blockdaemon.com, receive API keys immediately (no KYC for the free tier), and start making RPC calls to supported chains within minutes. The API is REST and JSON-RPC based. Authentication uses a Bearer Token (API key) in the Authorization header. Blockdaemon uses a Compute Unit (CU) model — different API operations cost different numbers of CUs depending on complexity. Simple balance queries cost fewer CUs than complex trace calls. Pricing Tiers Free: 3 million CU/month, 5 requests per second, 1 test key — suitable for development and prototyping. Starter: 15–65 million CU/month, 100 RPS, 10 live keys. Growth: 115–365 million CU/month, 200 RPS, overage at $0.000020/CU. Enterprise: 400M+ CU/month, custom RPS, 24/7 support, dedicated team, custom SLAs. Rate Limits Free tier: 5 RPS. Starter: 100 RPS. Growth: 200 RPS. Enterprise: custom. Limits apply per API key. Authentication API Key issued from app.blockdaemon.com passed as a Bearer Token in the Authorization header of each request. Multiple keys can be issued per account depending on tier. Compliance and Certifications Blockdaemon is ISO 27001 certified for information security management, SOC 1 Type I for financial controls, and SOC 2 Type II for security, availability, and confidentiality. This makes it suitable for regulated institutions such as banks and licensed fintechs in Nigeria that require auditable third-party infrastructure. Supported Protocols Ethereum, Solana, Cardano, NEAR Protocol, Sui, TON, Avalanche, Polygon, Bitcoin, Cosmos, Polkadot, and more — 12+ chains total. Nigeria Eligibility No geographic restrictions found in Blockdaemon documentation or terms. Nigerian developers can sign up with a standard email and begin using the free tier immediately. There is no requirement for a US bank account or restricted payment method for the free tier. Challenges and Gotchas (1) The Compute Unit model can be confusing — heavy workloads (trace calls, batch requests) consume CUs faster than expected. (2) Staking and MPC wallet products target institutional clients and may require enterprise contracts. (3) No fiat or NGN support — this is a pure crypto/blockchain infrastructure tool. (4) USSD and mobile money are not applicable to Blockdaemon. Company Background Blockdaemon was founded in 2017 and is headquartered in the United States. The company has raised over $300M in funding and counts major financial institutions among its clients. It manages hundreds of thousands of blockchain nodes globally. The company is a key infrastructure provider for institutional crypto adoption. FAQs Q: Can I use Blockdaemon for free in Nigeria? A: Yes.
