# Deposit

Deposit liquidity into vaults. Users can deposit coinA and coinB, and the associated LP Token will be minted to the user.

```typescript
const input_amount = toDecimalsAmount(3, 9).toString()
const InputType = {
  Both: 'both',
  OneSide: 'oneSide',
}

// Calculate deposit amount
const result = await sdk.Vaults.calculateDepositAmount({
  vault_id,
  fix_amount_a: false,
  input_amount,
  slippage: 0.01,
  side: InputType.OneSide,
})
// Build and send transaction
const tx = new Transaction()
const params: DepositParams = {
  vault_id,
  slippage: 0.01,
  deposit_result: result,
  coin_object_b: VaultsUtils.buildCoinWithBalance(
    BigInt(input_amount),
    '0x0000000000000000000000000000000000000000000000000000000000000002::sui::SUI',
    tx
  ),
  return_lp_token: true,
}
const lp_coin = await sdk.Vaults.deposit(params, tx)
if (lp_coin) {
  tx.transferObjects([lp_coin], '0x0..')
}
```
