Hack, Hustle, Build: The Magic of Hackathons

Hackathons have come a long way. What started as small, scrappy coding sessions between friends are now global events where people gather to build something new in just a day or two. They’re intense, collaborative, and a lot of fun. More importantly, they’re a great way to turn ideas into real products.

So what exactly is a hackathon? And why should you care if you’re in Web3?

What is a hackathon?

At its core, a hackathon is a short, focused sprint where small teams work on a project from start to finish. Usually lasting between 24 and 72 hours, it’s about coming up with an idea, building a prototype, and then showing it off at the end.

The “hack” is about problem-solving and creativity, not cybercrime.

The “marathon” is about endurance. Put the two together, and you get a few days of pure building energy.

Why blockchain hackathons matter

In Web3, hackathons are especially powerful. They’re a chance to build directly on live infrastructure, test new ideas, and even stress-test protocols.

For newcomers, it’s the perfect entry point, your first smart contract, your first dapp, your first time pulling data from an RPC. For experienced developers, it’s an opportunity to try something different, push the limits of a tool, or experiment with a use case you don’t normally get time for.

Who takes part?

You don’t need to be a hardcore developer to join a hackathon. The best teams usually mix:

- Builders writing smart contracts and connecting APIs‍

- Designers making sure things actually make sense to use

- Product minds who spot the problem and shape the solution

-Storytellers who can pitch an idea clearly

It’s the mix that often makes a winning project, not just the code.

Famous projects that started in hackathons

Hackathons aren’t just weekend fun, they’ve been launchpads for products many of us use today:

- GroupMe was built in a hackathon and later bought by Skype.

- 1inch started as a prototype at ETHGlobal and is now a major DeFi player.

- STEPN came out of a Solana hackathon and popularized “move-to-earn.”

These examples show how far a simple weekend project can go.

Why Tatum is doing hackathons

At Tatum, we believe the best way to show what’s possible in Web3 is to let people build with their own hands. Hackathons give devs the freedom to try bold ideas in a short burst of time. No long roadmaps, no months of planning, just you, your team, and a weekend to see what’s possible.

We’re hosting this hackathon to lower the barrier to entry for builders.

With our infrastructure in your corner, RPC Gateway or dozens of blockchains MCP server to plug your apps and agents directly into on-chain data.

All it takes is an API key and a few lines of code, and you’re off to the races.

What to build?

That part is up to you.

Some hackathons set a strict theme, like only DeFi, only gaming, or only a single chain, which narrows the possibilities.

That approach can be fun, but it also limits creativity.

At Tatum, we keep it open. In our events, you’re free to build whatever excites you, whether that’s a wallet feature, an analytics tool, a DeFi protocol, or even a lightweight game. The only rule is: ship something that works and makes life easier (or more fun) for users.

And don’t overthink it. Hackathons aren’t about perfection, they’re about getting an idea out of your head and into code.

Sometimes, the simplest project is the one that wins.

Wrapping up

Hackathons are chaotic, fast, and you might drink way more coffee than advised to. They’re one of the best ways to learn, connect with others, and maybe even kickstart a bigger project.

If you’ve been looking for an excuse to finally try building something on-chain, this is it.
