April 2026 performance summary for iotaledger Rust SDKs focused on defining a cohesive, business-friendly API surface and robust, scalable type system. The month delivered a significant consolidation of blockchain types into the iota-sdk-types crate across crates, enabling a single source of truth and simpler maintenance. A safer, Version-based type system was introduced (Version struct) with expanded Digest/Identifier/Tag capabilities and parsing improvements to reduce runtime errors and improve developer ergonomics. Core types such as SequenceNumber, IotaAddress, ObjectID, Digest, Identifier/StructTag/TypeTag, RandomnessStateUpdate/RandomnessRound, and Owner were replaced with SDK equivalents and re-exported to preserve existing imports, delivering a unified API surface. RPC/OpenRPC surface gained a cleaner boundary by removing schemars/jsonschema dependencies from core crates and centralizing schema in iota-json-rpc-types, improving build stability for wasm targets. Other notable work includes improvements to RandomnessStateUpdate/RandomnessRound, Addressing ownership enhancements, and Streamlined OpenRPC generation with new serde adapters and adapters for common primitives.
