If any transaction fails, the entire bundle is rejected. Solscan presents these relationships through structured visualizations, simplifying debugging and monitoring.<\/p>\n<p data-start=\"876\" data-end=\"1110\">Bundle checkers examine validator submissions across RPC nodes, verify signature dependencies, and optimize block packing.
