Mercury
Where it all begins. Feel the difference between centralized and distributed systems by attacking a virtual city, then watching the network survive.
Venus
Cryptography made tactile. Break hashes, forge signatures, and see the avalanche effect ripple through data in real time.
Earth
How strangers agree without trust. Simulate proof-of-work, proof-of-stake, and Stellar's federated consensus with living networks.
Mars
Your first wallet — safely. Sign transactions, watch fees settle, and understand every byte before touching real assets.
Jupiter
Programs that live on chains. Write, deploy, and break Soroban smart contracts inside a fully simulated blockchain.
Saturn
Assets, tokens, and the anchors that give them meaning. Issue your own token on a simulated Stellar network.
Uranus
Prove you own something the world can verify. Mint, trade, and understand NFTs beyond the hype.
Neptune
The final launch. Connect a real wallet and perform your first authenticated transaction on Stellar Mainnet.
