A decentralized exchange lets users trade directly from their own wallets. When you add liquidity, you become the counterparty for traders who swap against the pool.
What is providing liquidity?
Providing liquidity means depositing paired tokens into a DEX pool to earn trading fees. Traders pay a fee when they swap, and your share depends on your pool share; fees are not fixed.
How do you provide liquidity?

- 2Connect and choose a poolOpen the DEX, connect your wallet, and review the pool tokens and fee tier.
- 3Approve token spendingApprove only what you plan to deposit; native gas tokens do not need approval.
- 4Deposit and confirmEnter both amounts, review your share and the fees, then confirm. You receive LP tokens or a position NFT for your share.
