HyperliquidIntermediatePerpetual futures track an asset's price with no expiry, using funding payments between longs and shorts to stay near spot. Hyperliquid runs them on its own chain with an on-chain order book and the HLP vault. Leverage can erase your margin quickly.

EthereumAdvancedMEV is the profit made by choosing which transactions enter a block and in what order. On public DEX swaps, a bot can sandwich your trade and push you to the worst price your slippage allows. Tight limits, private RPCs and intents reduce the risk.

ChainlinkIntermediateA blockchain oracle brings outside data such as prices onto a chain so smart contracts can use it. Learn how push and pull feeds, Chainlink, Pyth and TWAPs work, how the Mango Markets attack exploited a thin market, and how protocols defend against bad prices.

GeneralIntermediateDeFi lending pools set interest rates from utilization and require more collateral than the loan. A liquidation is triggered when the health factor falls below 1. This guide explains LTV, liquidation thresholds and bad debt with a worked example and real incidents.

GeneralBeginnerA centralized exchange holds your crypto and matches trades on its own systems, while a decentralized exchange lets you swap from your own wallet. Compare order books and AMMs, custody, KYC, fees and real failures such as FTX, with a decision guide.

GeneralBeginnerDeFi provides financial services — trading, lending, borrowing — through public smart contracts instead of banks. It's permissionless, non-custodial and composable, with borrowing secured by over-collateralisation rather than credit checks, and no safety net if code fails.

EthereumAdvancedRestaking reuses staked ETH to secure extra services. In EigenLayer, restakers delegate to operators who run software for AVSs and earn more rewards, but each AVS can slash the stake allocated to it, stacking new risks on top.
#defi#security#staking
GeneralBeginnerIt means issuing a blockchain token backed by a legal claim on an off-chain asset like Treasuries, gold or loans. A custodian and legal wrapper hold the asset; the issuer mints tokens on deposit and burns them on redemption.

EthereumIntermediateLiquid staking gives you a token for staked ETH, like stETH or rETH, that keeps earning rewards while usable in DeFi. The main risks are contract bugs, slashing, the token trading below its ETH value, and stake centralization.

EthereumIntermediateUniswap prices tokens from its own reserves: in a constant product pool x * y = k, so the price is the reserve ratio and every trade moves it. Arbitrage keeps pools in line with the market, while LPs bear impermanent loss.

EthereumBeginnerA stablecoin is a token built to track $1. Its peg holds because anyone eligible can mint or redeem near $1, so arbitrage corrects drift. Backing ranges from fiat reserves to over-collateralized crypto to hedged derivatives.
