Share your transfer tool

The Scenario

Yesterday you documented what you’ve learned about Solana transactions. You broke down the anatomy of a transaction, explained how signatures and instructions work together, and published your understanding for others to learn from. Today, you flip the lens: instead of explaining what you know, you’re going to show what you’ve built.

In the real world, developers don’t just write code in isolation. They share tools, get feedback, and build in public. The transfer tool you built over the past few days, whether it sends native SOL using the Solana CLI or moves SPL tokens with spl-token, is something worth showing off. It’s a working piece of software that interacts with a global blockchain. That’s not nothing.

The Challenge

Package up and share your transfer tool with the developer community. Create a short, compelling post that walks through what you built, how it works, and what you learned along the way.

What You’ll Need

  • Your completed transfer tool from earlier in this arc
  • A screenshot or terminal recording of your tool in action
  • A transaction signature from a successful transfer on devnet (you can look it up on Solana Explorer)
  • A social media account (X/Twitter, LinkedIn, or wherever you engage with other developers)

Steps

  1. Gather your proof. Run your transfer tool one more time on devnet. Copy the transaction signature from the output. Paste it into the Solana Explorer (devnet) and take a screenshot of the confirmed transaction. This is your receipt: on-chain proof that your code works.
  2. Capture a demo. Take a screenshot or short screen recording of your terminal showing the transfer command and its output. If your tool accepts command-line arguments, show how you call it. If it uses prompts, show the full interaction. The goal is to let someone else see exactly what running your tool looks like.
  3. Write your post. Craft a short social media post that includes:
    • A one-sentence description of what you built (e.g., “I built a CLI tool that transfers SOL on Solana’s devnet”)
    • One thing you learned while building it (e.g., how transaction fees work, what a blockhash does, or why you need to sign with a keypair)
    • Your screenshot or demo
    • The link to your transaction on Solana Explorer
    • The hashtag #100DaysOfSolana
  4. Post it. Share your post on X/Twitter, LinkedIn, or any developer community you’re part of. Tag @solana if you’re on X. If you want to go the extra mile, reply to or quote someone else in the #100DaysOfSolana community to start a conversation about what you’ve each built.
  5. Engage. Scroll through the #100DaysOfSolana hashtag and find at least one other participant’s post. Leave a genuine comment, ask a question about their approach, or share something you noticed that was different from yours.

What Just Happened

You just did something most developers skip: you shared your work before it felt “ready.” Building in public is one of the most effective ways to grow as a developer. It forces you to articulate what you’ve done, which deepens your own understanding. It also puts your work in front of other people who are on the same journey, opening the door to feedback, collaboration, and accountability.

The transfer tool you built is a real piece of blockchain infrastructure. It constructs transactions, signs them with a cryptographic keypair, submits them to a network of validators, and produces a permanent, verifiable record on the Solana blockchain. That’s worth talking about, even if the amounts are small and the network is devnet. Every production tool started as a devnet experiment.
