The MegaETH DeFi ecosystem launched with over 50 applications on mainnet day in February 2026 and has grown into a cluster of spot DEXes, perpetual platforms, stablecoin systems, yield aggregators, lending protocols, and emerging consumer apps. Total value locked sits around $108 million as of April 2026, concentrated in a handful of flagship protocols while newer teams from the MegaMafia 2.0 accelerator continue to ship. This directory covers every major protocol sorted by category.

Core Infrastructure

Aave V3

Aave V3 deployed on MegaETH at mainnet launch as one of the largest DeFi protocols to commit to the chain. The Aave DAO received a five-year revenue guarantee of at least $10 million and 6% of the MEGA token total supply in exchange for the deployment. This makes Aave the primary money market on MegaETH for borrowing and lending against stablecoins and blue-chip assets.

Chainlink is embedded directly in the MegaETH execution environment as a native precompile. Contracts call a system address to retrieve price data instead of making standard oracle calls, delivering sub-millisecond price updates. MegaETH was the first blockchain to integrate Chainlink Data Streams as a precompile. The chain also supports Chainlink Data Feeds and CCIP for cross-chain messaging.

USDm

USDm is MegaETH's native stablecoin, built in partnership with Ethena Labs and backed by BlackRock's BUIDL Treasury fund. The yield from the Treasury reserves covers sequencer operating costs, which keeps transaction fees on the chain near zero. USDm serves as the base settlement currency for most DeFi on MegaETH. Full details in our Cap Labs and USDm guide.

Spot Trading

GTE

GTE is the main spot DEX on MegaETH, incubated by MegaETH Labs. It combines a central limit order book (CLOB) for large-cap assets with an AMM for niche tokens, covering both high-volume and long-tail trading pairs in a single interface. The hybrid structure gives GTE broad coverage without fragmenting liquidity across separate venues.

Kumbaya

Kumbaya is the largest application on MegaETH by total value locked, holding approximately $51 million as of late February 2026 and generating roughly $19,000 in daily fees. It is a decentralized exchange built around cultural assets, emphasizing speed and a clean interface. The protocol is part of the MegaMafia 2.0 cohort.

Perpetuals and Derivatives

World Markets

World Markets launched on February 17, 2026, as a unified DEX combining spot trading, perpetual futures, and undercollateralized lending in a single cross-margin account. Its ATLAS risk engine evaluates portfolios as a whole to determine margin requirements. The fee structure caps at $10 per trade regardless of size, which favors institutional flow.

GMX V2

GMX V2 deployed on MegaETH on March 30, 2026, supporting BTC, ETH, and SOL perpetuals with up to 50x leverage. The deployment includes a USDm-based GLV (GMX Liquidity Vault) that auto-rebalances liquidity across GM pools. GMX's cumulative volume across all chains exceeded $363 billion before the MegaETH launch.

Euphoria

Euphoria is a mobile-first derivatives platform that turns options and perps into single-tap trades. The protocol raised a $7.5 million seed round led by Karatage with participation from Figment Capital and Robot Ventures. Euphoria uses RedStone Bolt for oracle data and ran the Tapathon launch campaign in early 2026.

Stablecoins

Cap (cUSD and stcUSD)

Cap Labs produces cUSD, a synthetic dollar fully backed by fiat stablecoins with yield generated by whitelisted operators. Users deposit USDC or USDT and mint cUSD at 1:1. The staked version, stcUSD, accrues yield from operator trading activity. Cap operates a three-sided marketplace linking users, operators, and delegators who stake CAP tokens to vouch for operator performance.

Yield Aggregation

StackUp

StackUp aggregates yield opportunities across MegaETH's DeFi protocols into automated vaults. The protocol handles allocation, rebalancing, and compounding so users earn optimized returns without manually rotating across lending markets, LP positions, and other yield sources. StackUp is useful for USDm deposits because MegaETH's fast block times make frequent rebalancing economically viable.

Prediction Markets

PredictFi

PredictFi operates prediction markets on MegaETH covering politics, crypto, music, and sports. Markets resolve to binary outcomes with payouts handled on-chain. The fast block times reduce latency between event outcomes and settlement, which matters for high-turnover markets.

Emerging Projects (MegaMafia 2.0)

The MegaMafia 2.0 cohort brings 15 teams into a year-long accelerator that runs through 2026. Several projects from this batch are worth tracking.

These projects are in various stages of development. Some are live on testnet. Others are targeting mainnet launches during 2026. The MegaMafia accelerator program provides development support and ecosystem exposure in exchange for alignment with the MegaETH roadmap.

Finding Apps on MegaETH

The simplest way to discover applications on MegaETH is through Rabbithole, the official ecosystem portal. It combines a bridge, a swap interface, and an app directory showing live and upcoming projects. DeFiLlama and L2BEAT also track MegaETH with protocol-level metrics for users who want to compare TVL and activity across the chain.

Ecosystem maps go stale quickly on young chains. Before committing capital to any protocol, check its most recent audit, current TVL, and team activity. New deployments often carry more risk even when they share a known team or framework with established protocols.

How Protocols Connect

Most MegaETH protocols share USDm as their base stablecoin and rely on the same Chainlink precompile for oracle data. This creates strong composability. A trader can deposit USDm into StackUp's yield vault, use the vault token as collateral on Aave, borrow against it, and trade the borrowed funds on GTE or World Markets in a single session. The shared settlement layer and oracle infrastructure reduce the friction of combining protocols.

For context on the chain underneath these protocols, see our MegaETH overview or browse our full MegaETH guides library. For first-time users, our Rabbithole bridging guide and trading walkthrough cover the initial setup. Hyperliquid takes a different approach with a purpose-built L1 and a fully on-chain order book, covered in our Hyperliquid ecosystem guide.
