Chapter · Master Solana
DeFi on Solana
DeFi means decentralized finance, apps that let you trade, lend, or earn without a bank in the middle. Solana's low fees make it a natural home for this. You can swap tokens, provide liquidity to pools, or use lending markets, all from your own wallet. Well-known Solana apps include Jupiter for swaps and Raydium and Orca for trading pools.
Free to play. No ads, no token, no account needed to start.
What this lesson covers
Great power, real risk
DeFi is open and fast, but that cuts both ways. There is no manager to call if something breaks or you sign the wrong thing. Smart contracts can have bugs, prices can swing hard, and scam apps exist. Stick to well-known apps, start with small amounts, and read what you approve. None of this is financial advice, just basic safety.
What you get asked
What does DeFi let people do?
DeFi replaces the middleman with code. You can swap, lend, or earn straight from your wallet, with the rules enforced by programs on the chain.
On Solana, ___ is a popular app that finds the best route to swap one token for another.
Jupiter is a well-known Solana swap aggregator. It checks many pools at once to give you a good price when trading tokens.
Match each DeFi action to a plain description
Swapping trades tokens, pools hold the shared funds that make swaps possible, lending pays you to supply assets, and aggregators shop around for the best deal.
What is a real risk when using DeFi apps?
DeFi has no support desk to reverse mistakes. A buggy program or a malicious approval you sign can move your money, so caution matters a lot.
