To provide liquidity:
- Go to the Pools tab at app.ston.fi.
- Find the pool for the pair you want, or create a new one.
- Connect your wallet.
- Click Add liquidity.
- Enter the token amounts.
- Confirm the transaction in your wallet. Keep some Gram (formerly Toncoin) in your wallet for the network fee.
After confirming, you'll receive LP tokens that represent your share of the pool. These accrue swap fees automatically as people swap through the pool.
If you're adding liquidity to a custom token that doesn't exist as a pool yet, you'll need to create the pool first — see How to create a new liquidity pool.
V2 pools support Arbitrary Provision, which lets you add liquidity using only one token (the interface routes the necessary swap into the other side under the hood). This makes it easier to add liquidity when you only hold one of the two assets.
See the full liquidity provision guide.
