Go to Trade > 'Supply liquidity' and choose a liquidity pool. Pools incentivized with BALN will display an APY, calculated with(BALN allocation x USD value x 365) / Total USD value of pool x 100. Non-Balanced pools may offer liquidity rewards on another website, like Omm.
Choose the amount to supply. All pools require an equal value of two assets, except ICX/sICX, which only requires ICX.
Click Send to move each asset to the contract, then click Supply and complete the transaction.
Assets supplied to a Balanced-incentivized pool will be locked for the first 24 hours. If you supply more liquidity to the same pool within that time, the lockup period will be reset.
If you supply liquidity but don't see it in the UI, or you leave the page before the transaction is complete, click Supply for the same pool. You'll see your assets in the contract and can remove them.
Make sure you leave at least 2-3 ICX in your wallet to cover the transaction fees.
To withdraw assets from a pool, click Withdraw in the liquidity details section and choose the amount. Then click 'Withdraw liquidity' and complete the transaction.
If you're in the ICX/sICX pool, you can only withdraw the full amount. If you don't see your liquidity details for a third-party liquidity pool, make sure you haven't staked your LP tokens.
About the liquidity pools
Some of the liquidity pools on Balanced behave differently to others, as outlined below.
BALN/bnUSD & BALN/sICX
BALN supplied to these pools counts as staked BALN. It will accrue network fees and is factored into your voting weight.
sICX / ICX
The sICX/ICX pool is not a traditional liquidity pool. You only supply ICX, so it operates like an order queue that follows the First In First Out (FIFO) method. There's no risk of impermanent loss.
While your order is open, your ICX doesn't earn ICON staking rewards, but you will earn Balance Tokens.
Your order is filled when your ICX has been converted to sICX. You're no longer supplying ICX so you stop earning Balance Tokens, and can withdraw your sICX from the liquidity details section at any time. sICX is staked ICX, so it will earn ICON staking rewards.
Pools that aren't incentivized by Balance Tokens, like OMM/sICX, OMM/IUSDC, and OMM/USDS, don't require a 24 hour lockup. They do receive 50% of the trading fees generated by their assets
Liquidity providers may be able to earn liquidity rewards by staking their LP tokens on another platform (example: Provide liquidity for OMM). While your LP tokens are staked, you won't be able to view your liquidity details for that pool on Balanced, and will have to unstake your LP tokens before you can withdraw your assets from the pool.
