# Add liquidity (Mint nTokens)

## Deposit from wallet and Mint nTokens

Users can use the `batchBalanceAction` method to mint nTokens across multiple maturities:

```
# Deposit 100 DAI and 1 WBTC and Mint nDAI and nWBTC LP tokens.

mintNDaiAction = get_balance_action(2, "DepositUnderlyingAndMintNToken", depositActionAmount=10e18)
mintNWbtcAction = get_balance_action(4, "DepositUnderlyingAndMintNToken", depositActionAmount=1e8)
notional.batchBalanceAction(account.address, [mintNDaiAction, mintNWbtcAction], {"from": account})
```
