A leading overcollateralized lending protocol with isolation modes, flash loans, and many-chain deployments.

A version of Aave's lending protocol with configurable collateral and borrowing controls, including efficiency and isolation features.

An Ethereum scaling ecosystem whose Nitro software powers optimistic rollups, including Arbitrum One, with transaction execution off Ethereum and dispute resolution on the parent chain.

An automated market maker protocol that separates shared token accounting from pool-specific pricing, including weighted pools with configurable asset proportions and other specialized pool designs.

An Ethereum Layer 2 network with EVM-compatible execution, ETH-denominated gas, and settlement mechanisms that distinguish rapid local confirmations from Ethereum finality and bridge withdrawals.

A privacy-oriented network of sync domains aimed at institutional tokenized assets and workflows.

The leading oracle network for prices, proofs, and cross-chain messages (CCIP).

A decentralized lending protocol with version-specific market designs; Compound III markets use one borrowable base asset and a set of approved collateral assets with separate risk limits.

An automated market maker protocol whose StableSwap pools concentrate liquidity around a reference price relationship, with other pool designs such as CryptoSwap serving assets whose relative prices move.

A restaking protocol that lets participants allocate staked economic value to additional services, with service-specific operators, rewards, and slashing conditions beyond ordinary Ethereum validation.

A liquid-staking protocol whose Ethereum staking tokens, stETH and wstETH, represent claims linked to staked ether; LDO is a separate governance token.

A public Ethereum zkEVM rollup powered by the Lineth software stack, with execution on Layer 2 and validity proofs and settlement on Ethereum.

The collateralized stablecoin system behind Dai and the predecessor of the Sky ecosystem, with vault debt accounting, stability fees, liquidation mechanisms, and governance-controlled risk parameters.

Morpho's permissionless lending-market design in which individual markets have fixed core parameters and separate accounting.

The largest NFT marketplace by historical volume, a Web2 company on top of on-chain transfers.

An Ethereum scaling ecosystem that develops the OP Stack; OP Mainnet is a particular network built with that stack, and other deployments have their own network configuration.

The dominant AMM on BNB Chain, with farms, lotteries, and perpetual add-ons.

A protocol for trading future yield separately from principal by wrapping yield-bearing positions into standardized yield tokens and splitting their economic rights into dated principal and yield tokens.

The leading crypto prediction market, built on Polygon and later expanded.

An Ethereum rollup that executes EVM-compatible transactions on Layer 2 and uses validity proofs, published data, and Ethereum contracts to settle its state.

The stablecoin and governance ecosystem developed from MakerDAO, including USDS, its sUSDS savings-vault representation, and the SKY governance token.

An Ethereum validity rollup with Cairo-based execution and native smart-contract accounts; proofs establish valid state transitions while transaction receipts separately report execution and settlement status.

The leading Ethereum AMM. v2 popularized constant-product pools. v3 added concentrated liquidity. v4 adds hooks.

A version of the Uniswap automated market maker architecture built around a shared pool manager and optional hooks that customize pool behavior.

A protocol and software ecosystem for validity-proof-based chains, including ZKsync Era; a deployment's execution environment, data availability, and settlement configuration determine its actual guarantees.
