Best DeFi and Web3 Social DApps in 2026

Uniswap holds a key position in on-chain DeFi because it combines a battle-tested AMM with features that now cover far more than simple swaps.

The app supports Ethereum, major L2s such as Arbitrum, Optimism, Base, and Polygon, plus several EVM chains, so you can route most ERC-20 trades through one interface.

Uniswap v3 still handles most pool volume, yet v4 adds hooks that attach custom logic to pools for dynamic fees, on-chain limit orders, and automated liquidity control, with gas use far lower than earlier versions.

On top of that base, UniswapX introduces Dutch auction intent settlement that draws on both on-chain and off-chain liquidity, offers gasless swaps in some cases, and can extend to cross-chain execution, so you often see better net prices and fewer failed transactions.

dYdX focuses on perpetual futures that settle in USDC, with all positions managed from your own wallet on the dYdX Chain. The protocol runs on a dedicated Cosmos appchain, which uses validators and an in-memory order book to support rapid order updates without a central operator.

You get to access more than 200 markets through the web app or mobile apps, with limit, market, and stop orders, plus a full API for systematic strategies.

Perpetuals on dYdX use funding payments to keep contract prices close to spot, while cross-margin tools manage risk across open positions.

Fees stay competitive for high-volume accounts, and the app removes custodial layers, so margin stays in your address rather than on an exchange balance sheet. dYdX suits you if you already feel comfortable with leverage and want a derivatives DApp that avoids full central custody.

Aave turns major tokens into working collateral instead of idle balances in a wallet. You supply assets to shared pools, receive interest, and unlock a borrow limit that depends on collateral quality, set LTVs, and pool health.

Rates adjust with pool use, so strong loan demand often leads to higher returns for depositors.

With v3, Aave adds isolation mode, efficiency mode, and strict supply caps. Those tools limit damage if one asset depegs or loses depth. Support for networks such as Arbitrum, Optimism, and Base keeps gas costs low enough for medium-sized positions.

Aave suits you if you want flexible DeFi credit against blue chip assets and accept that any loan can face liquidation when markets move fast.

Lido lets you stake ETH and receive stETH, a token that tracks your share of pooled validators and updates your balance as rewards accrue. That setup removes the 32 ETH threshold and allows any amount, with rewards tied to Ethereum proof-of-stake yields.

For DeFi use, you can switch to wstETH, a non-rebasing version that suits money markets and derivatives platforms on Ethereum and major L2s.

Lido now serves as one of the largest providers in the ETH staking segment, which means deep liquidity and many integrations (but also a real debate around validator concentration).

stETH and wstETH appear in lending markets, DEX pools, and structured products, so you can stack base staking yield with extra rewards if you accept more risk.

At the protocol level, Lido moves toward a more modular v3 design with stVaults and distributed validator tech, which aims to broaden the node set while keeping governance in the Lido DAO.

Lens Protocol works as a base social layer rather than a single app. You claim a Lens profile, which sits as a Profile NFT or smart account that tracks your posts, follows, and social graph across all Lens apps.

The move to Lens Chain turns that graph into a SocialFi network on an Ethereum L2 with very low fees in GHO and social data stored on-chain through Grove.

You then sign in to clients such as Lenster, Phaver, or other SocialFi frontends with the same profile, so your followers, posts, and handle no longer depend on one company or one app.

Open Actions and V2 modules add hooks inside posts that connect to other smart contracts, so creators can gate content, route rewards, or link to DeFi actions without new accounts on each site.

Lens fits you if you want a portable social identity with on-chain control instead of closed web2 feeds.

Galxe is placed in a slightly different corner of web3 because it connects projects to users through quests, rewards, and identity instead of pure trading or lending.

Quest pages list tasks across many chains, with rewards such as OAT badges, NFTs, loyalty points, and token drops once you complete specific on-chain or social actions. That setup turns Galxe into a campaign hub where you track progress, claim rewards, and filter quests by network, partner, or requirement.

When it comes to identity, Galxe Passport and the Galxe Identity Protocol give you a reusable web3 profile with sybil resistance and optional KYC, backed by zero-knowledge proofs for traits such as uniqueness or residency.

Projects can plug this stack into allowlists, raffles, or loyalty systems so rewards reach real users instead of bots. Newer modules, such as Smart Savings, even link into DeFi by pooling balances for cross-chain gas use and yield, which fits users who want one quest and identity hub that also touches DeFi rails.
