Key Features

  • Unified Configuration: Consistent Config struct across all SDKs with apiKey, endpoint, timeout, retries
  • Error Hierarchy: Standard error types (ApiError, ValidationError, TimeoutError, AuthenticationError)
  • Retry Logic: Automatic exponential backoff retry for transient failures
  • WebSocket Support: Real-time subscriptions for blocks, addresses, and mempool
  • Type Safety: Strong typing in all languages with comprehensive type definitions
  • Documentation: Doc comments and examples in all implementations

Implementation Details

Phase 1: Core Infrastructure

  • Wallet SDK (key management, signing)
  • RPC SDK (blockchain queries, subscriptions)
  • Storage SDK (file operations, pinning)

Phase 2: Platform Services

  • Database SDK (multi-model data storage)
  • Hosting SDK (decentralized web hosting)
  • Bridge SDK (cross-chain transfers)

Phase 3: DeFi Services

  • Mining SDK (pool integration)
  • Economics SDK (pricing, staking)
  • Governance SDK (DAO, voting)

Phase 4: Privacy & Contracts

  • Privacy SDK (confidential transactions)
  • Contract SDK (smart contract interaction)

Phase 5: Language Expansion

  • Extended all services to C, C++, C#, Ruby
  • Complete feature parity verification

Technical Notes

  • C/C++: Header-only declarations with implementation stubs for HTTP client integration
  • Rust: Async runtime using tokio with reqwest HTTP client
  • Python: Both sync and async APIs using httpx
  • Go: Context-based cancellation and goroutine-safe clients
  • Swift: Modern Swift 5.5+ concurrency with async/await
  • Kotlin: Coroutine-based with Flow for streaming
  • Java: CompletableFuture with OkHttp client
  • C#: Task-based async with HttpClient
  • Ruby: Faraday HTTP client with automatic retries
