Explore Solana Explorer

The Scenario

Over the past four weeks, you’ve built wallets, read on-chain data, sent transactions, and explored the account model. You’ve done all of this through CLI commands and scripts. But there’s a faster way to browse on-chain data when you just want to look around: Solana Explorer. It’s a web interface that lets you search for any address, transaction, or program and view its data in a readable format. Think of it like a database admin tool, but for a public blockchain.

Today is about exploring. No specific build target, no starter code. You’re going to dig around on-chain, find something you think is interesting, and share it.

The Challenge

Using Solana Explorer, find something interesting on devnet or mainnet and write a short explanation of what you found. This could be a large transaction, an active program, a wallet with unusual activity, a token you haven’t heard of, anything that catches your attention.

What You’ll Need

Solana Explorer

Where to start

If you’re not sure what to look for, here are a few starting points:

Paste one of the transaction signatures from a transfer you sent in Arc 3 into the Explorer search bar. You’ll see the full transaction details: the accounts involved, the instructions that were executed, the fees paid, and whether it succeeded or failed.

Switch the Explorer to mainnet (using the network dropdown in the top bar) and search for the Token-2022 program address you queried in Arc 2: TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb. Compare what you see there with what you saw on devnet.

Browse the Solana Explorer programs page to see a list of verified programs running on mainnet. Pick one and look at its recent transaction activity.

Look at the Explorer homepage on mainnet. It shows live network stats: transactions per second, the current slot number, and recent activity. Watch the slot numbers tick up in real time to get a feel for how fast the network moves.

What to pay attention to

As you explore, notice how everything connects. Transactions reference accounts. Accounts are owned by programs. Programs process instructions. Every piece of data you’ve been reading through RPC calls over the past weeks is visible here in a different format.

Also, notice what’s public. Wallet balances, transaction histories, program activity. None of this data is hidden. This is the same principle you’ve been working with throughout this program, but seeing it in a visual interface makes its scale more concrete.
