What Our Sepolia Explorer Offers

Our Sepolia Explorer is built only for Ethereum testnet work and helps you:

See How Sepolia Transactions Really Execute

Sepolia transactions are meant to expose real execution behavior, not just mere ultimate results. Our Sepolia Explorer shows full call flows and execution details, including invocation order and gas usage. You can follow every step in order and understand how a transaction behaves on Sepolia.

Review Sepolia Transactions with Full Context

Track Sepolia Asset and Balance Changes Clearly

Turn Sepolia Execution Data into Clear Decisions

How to Analyze an Intricate Sepolia Transaction in 3 Steps

Our Sepolia Explorer gives you a simple workflow to review Sepolia transactions before you ship anything to mainnet.

Load the Sepolia Transaction View

Enter the Sepolia transaction hash into our Sepolia Explorer and open the main transaction view. Access the full execution context and prepare to inspect how the transaction runs on Sepolia.

Examine the Sepolia Execution Flow in Detail

Switch focus to Sepolia invocation flow and follow the full call path in order. Review internal calls, events, and reverts. Identify unusual delegate calls, router hops, or unexpected handlers early.

Review Fund Flow and Balance Impact on Sepolia

Check Sepolia fund flow and balance changes across all affected addresses and contracts. Track how assets move through contracts. Confirm who gained, who lost, and where value finally settled on Sepolia.

Use Cases

Developers

Review Sepolia Contracts Before Mainnet

Use Sepolia Explorer to trace real Ethereum testnet execution, gas use, and reverts, so you catch issues early and deploy with clear insights.

Security Researchers

Trace Sepolia Risks at Execution Level

Employ Sepolia Explorer to follow deep calls and failure paths, helping you locate risk sources during audits and investigations.

High-Frequency Traders

Verify Sepolia Transaction Results Accurately

Leverage Sepolia Explorer to read real Sepolia costs, fund flow, and execution impact. Make better arbitrage decisions.

Key Features

Sepolia-Native Invocation Flow

Sepolia is used to test real Ethereum execution before mainnet. Call order and failure paths matter more than final results. Our Sepolia Explorer shows the full invocation flow exactly as Sepolia runs it, so you can seamlessly follow every internal call and execution step without hidden or collapsed data.

Try This Transaction

Complete Sepolia Fund Flow Visibility

Sepolia transactions often involve complex asset movement across multiple contracts. Final balances alone is far from enough to explain what happened. Our Sepolia Explorer tracks fund flow across the entire transaction, showing where assets move, which contracts are involved, and how each transfer connects.

Sepolia-Wide Balance Change Tracking

A single Sepolia transaction usually affects many addresses. Partial views tend to hide impact. In this regard, our Sepolia Explorer can show you balance changes for every involved address, so you can clearly see who gained, who lost, and how fund shifted across Sepolia.

Community Endorsement

"Anytime a post-mortem needs to be done on an attack, these are the explorers to use. They give fine-grained details on exactly how the hacks go down."

@PatrickAlphaC

"The Phalcon tx explorer by @BlockSecTeam is 🔥 One particular useful feature is the Fund Flow, which provides a visual summary of value movement on a single tx 🤯"

@Quantaraum

"Recently, I've been using the Phalcon Transaction Explorer @Phalcon_xyz and am impressed by its debugging feature. It's been an absolute lifesaver during my recent hack investigations! Any recommendations for other tools that could aid in hack probes?"

@i2huer

"– @Phalcon_xyz (built by @BlockSecTeam ), advanced explorer. • Visualized balance changes and funds flow; • Function level analysis with source code view; • Simulation of Ethereum & BSC transactions. Best for: On-chain analysts, devs."

"a major thank you to the @phalcon_xyz team whose advanced monitoring system caught this and alerted the crew a seemingly innocuous 0 ETH transaction with encrypted call data….that would’ve drained the full 477 WETH treasury"
