Share your explorer

The Scenario

Yesterday, you wrote about the Solana account model, translating what you’ve learned into your own words. That kind of reflection is powerful for your own learning, but it also helps others who are a few steps behind you on the same path. Today, you’re going to take that a step further. You’ve been spending time in Solana’s block explorers, poking around accounts, inspecting transactions, and making sense of how data lives on-chain. Now it’s time to show the world what you’ve found.

Think of this like a developer sharing a cool debugging trick or a favorite dev tool on social media. You’ve got something worth showing off: a real, working knowledge of how to navigate the Solana blockchain using an explorer. That’s not trivial, and other developers will find it genuinely useful.

The Challenge

What You’ll Need

  • Access to a Solana block explorer (pick your favorite: Solana Explorer, Solscan, or SolanaFM)
  • A wallet address or transaction signature from your previous days’ work on devnet
  • A social media account (X/Twitter, LinkedIn, or wherever your developer community hangs out)
  • A screenshot tool (your OS’s built-in one works fine)

Steps

  1. Pick your best explorer moment. Open the explorer you’ve been using throughout this program and find something interesting to show. Good options include:
    • Your own wallet account on devnet, showing the balance and transaction history
    • A transaction you submitted, with the instruction logs expanded
    • A program account, showing how code and data are stored separately
    • A comparison of how the same account looks across two different explorers
  2. Take a clear screenshot. Make sure the screenshot captures something meaningful. Expand the details panel, show the account’s data fields (owner, lamports, executable flag), or highlight the instruction logs of a transaction. If your explorer supports it, use the devnet cluster toggle so people can see you’re working on devnet.
  3. Write a short post. Your post should answer three questions:
    • What are you looking at? (e.g., “This is a devnet transaction where I transferred SOL between two accounts”)
    • What’s one thing you noticed or learned? (e.g., “I didn’t realize the explorer shows you exactly which programs were invoked in a single transaction”)
    • Which explorer are you using, and would you recommend it?
  4. Share it. Post your screenshot and write-up to X/Twitter, LinkedIn, or your preferred developer platform. Tag it with #100DaysOfSolana so the community can find it. If you’re on X, consider tagging @solaboratory (the Solana Explorer creators) to connect with the ecosystem.

What Just Happened

You just did something that most developers skip: you shared your learning process publicly. That takes confidence, and it matters more than you might think. When you post about a tool like Solana Explorer and explain what you see on screen, you’re doing two things at once. First, you’re reinforcing your own understanding. Writing a short explanation of a transaction’s instruction logs forces you to actually understand what those logs mean. Second, you’re creating a breadcrumb trail for other developers who are curious about Solana but haven’t taken the leap yet.

Block explorers are the debugger of the blockchain world. In Web2, you’d use browser DevTools to inspect network requests or check the state of your application. On Solana, explorers give you that same visibility into on-chain state: account balances, program ownership, transaction histories, and instruction-level logs. The fact that all of this data is public and transparent is one of the things that makes blockchain development fundamentally different from what you’re used to. Getting comfortable reading an explorer is a skill you’ll use every single day as a Solana developer.
