v1.0.0

Breaking / Notable

• Dependency/features reshape for Alloy -> smaller build size
• tracing became an optional dependency gated by the tracing feature
• Error::RpcError no longer wraps the inner value in Arc.
  • Error no longer Clone-able
  • If Error cloneability is needed, it can be wrapped whole in Arc.

Added

• HTTP-based subscriptions (polling) behind feature flag
  • Adds polling subscription backend that can be enabled via:
    • features = ["http-subscription"]
    • RobustProviderBuilder::allow_http_subscriptions(true)
    • configurable RobustProviderBuilder::poll_interval
• Robust watch_blocks function support
• Much broader eth_* RPC method coverage
• Added Example: examples/get_latest_block.rs.

Changed

• Error model expanded and centralized
• Subscription connection being closed by the node is treated as a failover-worthy error.

Fixed

• Certain invalid filter / block errors are treated as non-retryable (reduces pointless retries).

New Contributors

• @smartprogrammer93 made their first contribution in #32

v0.1.0

Initial release

Highlights

• Automatic retries - Exponential backoff with configurable retry attempts for transient failures
• Transparent failover - Seamlessly switch between primary and multiple fallback RPC endpoints
• Bounded timeouts - Per-call timeouts prevent indefinite hangs on unresponsive nodes
• Resilient subscriptions - WebSocket block subscriptions with automatic reconnection and lag detection
• Fluent builder API - RobustProviderBuilder for easy configuration of timeouts, retries, and fallbacks
• Provider conversion traits - IntoRootProvider and IntoRobustProvider for flexible provider handling
• Extensibility - try_operation_with_failover for wrapping any RPC call with full resilience logic

Notes

⚠️ This is an early release under active development. APIs may change without notice. Currently not all eth rpc endpoints are available
