What Our Optimism Explorer Offers

Our Optimism Explorer is built for OP Stack-based execution, so it can allow you to:

Trace Optimism Fund Flow and State Changes Clearly
A single Optimism transaction can move assets and update state across many contracts. Our Optimism Explorer visualizes fund flow and balance changes in one view and exposes field-level state updates, helping you see what changed, where it changed, and who was affected.
Reveal Real Optimism Transaction Execution
Reproduce and Simulate Optimism Transactions Accurately
Turn Optimism Data into Actionable Insight

How to Analyze an Intricate Optimism Transaction in 3 Steps

Use our Optimism Explorer, Phalcon Explorer, to break down complex Optimism activity with execution path, simulation, fund flow, and balance changes.

1

Load the Transaction View

Enter the transaction hash into the search box and press enter to load the main GUI. Open the full transaction view and prepare to review OP Stack execution details, internal calls, and Optimism-specific behavior clearly on our Optimism Explorer.

    2

    Switch to Full-Screen Mode

    Click the top-right button to enter full-screen mode in Phalcon Explorer. Expand the workspace, reduce distractions, and focus on deep Optimism transaction analysis across execution, simulation, and state impact without interruption.

      3

      Review Core Analysis Modules

      Review transaction details through Invocation Flow, Fund Flow, Balance Changes, and State Changes first. Then use Simulator and Debugger to replay risky or attack-like behavior, inspect parameters and returns, and confirm what changed and why.

        Key Features

        invocation flow

        Optimism-Native Invocation Flow Visibility

        On Optimism, a single transaction often expands into many layered internal calls under the OP Stack model. Generic explorers collapse this logic. Our Optimism Explorer visualizes the complete invocation flow with trace-level detail and Optimism event logs, letting you follow execution step by step and understand how complex Optimism transactions actually unfold.

        Optimism-Aware Execution Debugging

        Debug on Optimism based on execution rules and gas behavior. Our Optimism Explorer lets you navigate internal and external calls with full execution context. You can directly inspect parameters and return values at each step, using source code views to pinpoint where Optimism-specific logic breaks during security reviews.

        Optimism-Accurate Transaction Simulation

        Optimism simulation must match real execution conditions. Our Optimism Explorer allows you to simulate transactions from any Optimism block using the same inputs, execution order, and OP Stack rules. Results are reproducible and easy to inspect, helping teams validate behavior, analyze attacks, and resolve Optimism issues faster together.

        Transaction-Level Fund Flow on Optimism

        Optimism transactions can move assets through many contracts in a single execution. Our Optimism Explorer tracks fund flow with granular precision, showing where assets move, when transfers occur, and which contracts are involved. This exposes hidden asset paths that generic explorers miss and clarifies real Optimism fund movement.

        Address-Level Balance Changes on Optimism

        A single Optimism transaction can affect many addresses at once. Our Optimism Explorer displays token balance changes for every involved EOA and contract before and after execution. This helps you quickly identify impacted addresses, abnormal movements, and potential attacker or victim accounts during Optimism investigations.

        Field-Level State Changes on Optimism

        Many Optimism state updates never appear clearly in logs. Our Optimism Explorer exposes contract state changes at the field level, showing exactly how variables update during execution. Instead of viewing mere transaction success, you can gain clear insight into how Optimism contracts evolve after every transaction.
