Step execution is now built on a task pipeline architecture. Shared logic like balance checks and transaction preparation lives in the core SDK, while ecosystem packages implement only chain-specific tasks. New chain integrations ship faster and cross-chain debugging is more straightforward.

The Solana SDK provider now supports Jito bundles for atomic, MEV-protected transaction execution. Enable it with a single jitoBundle flag in your route options to submit multi-step Solana transactions as all-or-nothing bundles. The SDK auto-detects Jito-capable RPCs, submits to multiple endpoints in parallel for redundancy, and returns bundle IDs with per-transaction confirmation status for full observability.
