A 'synthetic dollar' that holds its $1 value not with bank reserves but with a delta-neutral basis trade — long staked crypto collateral, short an equal notional of perpetual futures — passing funding + staking yield to sUSDe stakers.

An AMM invariant that blends constant-sum and constant-product curves to give like-pegged assets (stablecoins, wrapped assets) dramatically lower slippage than Uniswap-style pools, making Curve the deepest stablecoin liquidity venue in DeFi.

A generalized AMM using a weighted geometric-mean invariant that turned index funds inside out — LPs get paid to be rebalanced — and helped ignite DeFi Summer with one of the first liquidity-mining programs, before a 2025 rounding-error exploit drained $128M from its V2 stable pools.

DEX that replaced the constant-product curve with a Proactive Market Maker (PMM) algorithm anchoring concentrated liquidity to an external oracle price.

Trader Joe's bin-based concentrated-liquidity AMM that made LP positions fungible and priced fees dynamically with an on-chain volatility accumulator.

A single-contract DEX (formerly CrocSwap) that fused full-range, concentrated, and knockout limit-order liquidity into one AMM — technically ahead of Uniswap v4 but commercially eclipsed after points-driven TVL evaporated.

A BNB Chain-native 'stableswap 2.0' AMM that replaced Curve-style paired pools with single-sided deposits priced by an asset-liability coverage ratio, hit ~$215M TVL within months, spawned its own veToken 'WOM Wars' — then bled to near-irrelevance as stableswap volume consolidated elsewhere.

A multichain DEX that replaced AMM bonding curves with an RFQ model in which professional market makers cryptographically sign off-chain quotes for zero-slippage, MEV-protected on-chain settlement.

Intent-based trading protocol where competing solvers settle batched orders via uniform-price 'coincidence of wants' auctions, shielding traders from MEV.

A Gelato spin-off that wrapped Uniswap V3 concentrated-liquidity positions into fungible, auto-managed ERC-20 vaults, briefly commanded ~25% of Uniswap V3 liquidity via MakerDAO's G-UNI integration, then pivoted to B2B onchain market making for token issuers after its whale-dependent TVL collapsed.

Automated concentrated-liquidity management protocol (formerly Visor Finance) whose 'Hypervisor' vaults actively rebalance Uniswap v3-style LP positions — twice rebuilt after major exploits.

Uniswap liquidity engine that evolved from fungible ERC-20 wrappers for Uniswap v3 positions into the leading 'shapeshifting' Uniswap v4 hook DEX, before an $8.4M rounding-error exploit in September 2025 forced a permanent wind-down.

A DeFi 'risk tranching' protocol that let liquidity providers split yield-farm exposure into senior and junior tranches, briefly a DeFi-winter darling before its TVL and token collapsed and it pivoted to fixed-income yield vaults.

One of the first protocols to split yield-bearing tokens into principal and tradable future-yield tokens, letting farmers sell unrealized yield in advance — it pioneered the mechanism Pendle later dominated, and survived by rebranding into Spectra.

Perpetual futures DEX that invented the 'virtual AMM' — an x*y=k curve with no real liquidity that priced leveraged perps against a USDC vault, scaled to $19B+ volume, then died of chronic long-short skew.

Oracle-priced decentralized perpetuals exchange whose pooled-counterparty GLP token and fee-sharing 'real yield' tokenomics defined the L2 perps category — later validated by a V2 redesign and stress-tested by a $40M V1 exploit.

The first fully on-chain options AMM, which priced options via a market-adjusted Black-Scholes model and hedged LP risk with perps, before abandoning the AMM design for an app-chain orderbook and rebranding to Derive.

Pseudonymous solo-dev options protocol that pioneered the peer-to-pool model — buyers trade against a pooled counterparty instead of an order book — surviving a launch-day bug, multiple full rewrites, and a bear market to remain the largest on-chain options AMM.

An oracle-free perpetual-options protocol that reinterprets Uniswap v3/v4 concentrated-liquidity positions as short options, letting anyone mint, trade, and market-make never-expiring puts and calls on any token.

Cross-chain decentralized derivatives protocol that was the first to implement 'everlasting options' on-chain, pricing perps and options against pooled LP capital via an oracle-fed proactive market maker (DPMM).

A Substrate-based appchain for prediction markets and futarchy in the Polkadot/Kusama ecosystem that shipped novel market-maker and court mechanisms but never found sustained trading volume.

SushiSwap's open-source token-launchpad suite (crowdsale, Dutch, and batch auctions) that raised ~$340M for BitDAO, survived a whitehat-averted $350M bug, suffered a $3M frontend supply-chain hack, and was sunset in early 2023 for lack of resources.

Simon de la Rouviere's 2017 protocol-design framework for tokenized curation of information via continuous (bonding-curve) tokens — the concept never shipped as a single protocol but seeded bonding curves, TCRs, and continuous token models across the ecosystem.

Aragon Black's DAICO-style continuous-fundraising suite for Aragon DAOs — a batched Bancor bonding curve plus a governable 'tap' — that was deprecated as a product but powered Aavegotchi's $30M+ GHST token sale for 2.5 years.

Fairmint implemented Thibauld Favre's Continuous Organization model — a bonding-curve 'Decentralized Autonomous Trust' that continuously sells revenue-backed securities — before pivoting to legally simpler Rolling SAFEs and onchain cap-table infrastructure.

A token-incentivized decentralized mixnet that pays independent node operators to shuffle encrypted 'sphinx' packets, aiming to protect network-level metadata against even nation-state surveillance.
