DeFi is a set of permissionless financial services (lending, trading, savings, derivatives) built on public blockchains that run via smart contracts instead of traditional intermediaries. It lets users interact directly with protocols using wallets, enabling composable services and transparent on‑chain transaction history.

Most DEXs use automated market makers (AMMs) where pools of token pairs follow a formula (e.g., x*y=k) so swaps move the pool balance and change the implied price. Price slippage depends on pool size and trade size, and large trades move the price exponentially compared with central limit order books.

Staking secures a blockchain by locking native tokens and earning protocol rewards; lending lets users supply assets to earn interest while borrowers pay to borrow; yield farming typically means moving assets across protocols to maximize returns via interest, liquidity provider fees, and reward token incentives. Each has distinct risk profiles: staking relies on protocol consensus, lending on smart contract and counterparty risk, and farming on incentives and tokenomics.

Start with a hardware or reputable non‑custodial wallet (Metamask or Ledger), transfer a small amount to test (covering estimated gas), and use a well‑known protocol with audited contracts (Uniswap/Aave/Maker). Limit exposure, read the protocol's docs, verify contract addresses from official sources, and never share private keys or seed phrases.

Primary risks are bugs, oracle manipulation, governance attacks, and rug pulls. Mitigate by using audited, battle‑tested protocols, diversifying, avoiding unaudited token incentives, checking audits/bug bounty history, and limiting the amount you allow for token approvals.

Bridges lock assets on one chain and mint wrapped representations on another or route liquidity via liquidity pools/relayers; many use multisig or federated validators. Bridges have been the single largest source of losses historically—use audited, widely used bridges, limit amounts, and prefer bridges with on‑chain finality proofs.

Yes—most jurisdictions treat token sales, swaps that realize gains, and generated income (interest/yield/token rewards) as taxable events or income. Keep detailed on‑chain records, export transaction histories, and consult a tax advisor experienced with crypto to correctly classify events (income vs capital gains).

Impermanent loss happens to liquidity providers when the relative price of pooled tokens diverges from deposit time, reducing value versus simply holding the assets. It's most relevant for volatile pairs and small pools; choose stablecoin pairs or concentrated liquidity strategies (Uniswap v3) to reduce exposure.

Oracles feed off‑chain data (prices, events) into smart contracts; Chainlink is a widely used decentralized oracle network that aggregates price feeds to reduce single‑point manipulation. Reliable oracles are critical for lending collateralization checks, liquidations, and derivatives pricing—weak or manipulated oracles can cause major protocol losses.

Evaluate audits and bug‑bounty history, TVL and on‑chain activity, multisig/governance structure, open‑source code transparency, tokenomics, and track record during stress events. Also review community governance proposals, third‑party risk scores, and whether reputable teams or backers are involved.
