Uniswap is the foundational decentralised exchange (DEX) on the Ethereum blockchain, fundamentally reshaping how digital assets are traded. As a permissionless, automated market maker (AMM), Uniswap allows anyone to swap a vast array of ERC-20 tokens directly from their self-custody wallets, without intermediaries. Its open-source nature and pioneering design have made Uniswap a cornerstone of decentralised finance, processing billions in daily trading volume across various Ethereum-compatible networks.

scam or legit
Legit. Uniswap shows the markers we look for in a credible operator: identifiable team, working product, transparent terms and consistent withdrawal performance. No platform is risk-free, but on the evidence available there is no reason to consider Uniswap a scam.

What you get
Permissionless swaps
Trade any ERC-20 directly from your self-custody wallet via an automated market maker — no account, no KYC, no custodian.
Multi-chain
Live on Ethereum and major L2s (Arbitrum, Optimism, Base, Polygon and more), so you can swap where fees are lowest.
Open-source & audited
The protocol's contracts are public, audited and battle-tested through billions in volume — the blueprint most other DEXs copy.
Provide liquidity
Earn a share of trading fees by supplying liquidity — with concentrated-liquidity control in V3, and impermanent-loss risk to understand first.
Who it's for
Self-custody users who want to swap tokens or earn LP fees on-chain without trusting a centralised exchange — comfortable verifying contracts and managing gas.

Frequently asked questions
Is Uniswap safe?+
The protocol is audited, open-source and the most battle-tested DEX in crypto. The risks are around it — scam tokens, fake front-end sites and risky approvals — not the core contracts.
Does Uniswap hold my funds?+
No. It's fully non-custodial — you swap directly from your own wallet and keep your keys throughout. There's no account and no custodian.
How do I avoid scam tokens on Uniswap?+
Anyone can list a token, so always confirm the official contract address from a trusted source (the project site or a reputable explorer) before swapping, and be wary of tokens you can't sell.
What are Uniswap's fees?+
You pay a small protocol/LP fee per swap (commonly 0.05%–0.30% depending on the pool) plus network gas. Using an L2 dramatically lowers the gas cost.
