What Solana Explorer Taught Me That My Code Couldn't

Source: Dev.to

Introduction

Four weeks into #100DaysOfSolana, I finally stopped treating Solana Explorer as “just a checker” and started using it as a learning tool. The shift changed how I approached development.

Key Takeaways

1. Programs are just accounts too

   • Example: the SPL Token program (TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA). In Explorer it appears like any other account, with an owner, a balance, and a data field. The only difference is the Executable: true flag. That single boolean separates a wallet from a smart contract on Solana. Seeing it in the UI reinforces what the docs describe.

2. Everything is public, and that’s the point

3. The explorer is your debugger

   • It shows exactly which instruction failed and why. I had a failed transfer in my devnet history; expanding the logs revealed the error: insufficient lamports. The same information was in my terminal, but Explorer made it much easier to identify the offending account and trace the problem step‑by‑step.

Using Solana Explorer

I use the official Solana Explorer for most of my devnet work. It’s clean, handles devnet/mainnet switching effortlessly, and the raw transaction view is invaluable when you’re still learning how everything fits together.

Alternative: Solscan

For mainnet work, Solscan can feel more convenient because it provides labeled accounts and clearer token flow visualizations.

Recommendation

If you’re early in your Solana journey, bookmark Explorer and open it every time you send a transaction. Don’t just check if it succeeded—expand every section, click into the accounts, and read the logs. It will teach you more than staring at documentation ever will.
