LEVEL 01 · Basic
Solana Foundations
Understand the network, protect your keys, and read on-chain evidence.
Read and practice without a connection
This free pack contains the lesson explanations, diagrams, guided practice, self-checks, references, and the optional local lab files listed in each lesson. It contains no scored checkpoints, level-exam questions, answers, or completion records. Those remain available online through a free learner account; reading never requires an account or a wallet.
Source pages need an internet connection to open. Some included Devnet exercises also need a connection when you choose to run them. Never enter a recovery phrase or private key into a lesson or lab.
