Understanding Solana basics before you download a wallet
Most beginner guides jump straight to an app store download. That works for some people, but when a step fails — during seed phrase backup or devnet switching — it helps to know what a wallet actually controls on Solana.
Your wallet holds keys, not coins
On Solana, tokens and account data live on the network. Your wallet app stores a private key derived from your seed phrase. That key lets you sign transactions that move SOL or tokens between accounts. If you lose the phrase, the on-chain assets remain, but you lose the ability to sign for them.
Accounts are the basic unit
Everything on Solana — your SOL balance, a token balance, a program's code — exists in an account. Each account has an address (a long string of letters and numbers). Your wallet address is one account. When someone sends you SOL, they instruct the network to debit their account and credit yours.
Programs vs wallets
Wallets are apps you install. Programs (sometimes called smart contracts on other chains) are code deployed on Solana that runs when invoked by a signed transaction. Swapping tokens on a decentralized exchange, for example, involves your wallet signing a transaction that calls a program. You do not install those programs on your phone — you interact with them through your wallet.
Validators keep the ledger
Validators are computers that propose and confirm blocks of transactions. You do not need to run one to use Solana. As a beginner, it is enough to know that when your wallet shows "confirmed," a supermajority of validators agreed your transaction is valid.
Devnet vs mainnet
Devnet is a public test network. SOL there has no monetary value. Mainnet is the live network where real value moves. Wallet apps let you switch between them in settings. We always practice on devnet in our sessions before discussing mainnet.
