mint

Mint an exact number of vault shares to a receiver, pulling the required USDC from the caller.

Signature

function mint(uint256 shares, address receiver) external returns (uint256 assets);

Parameters

Name	Type	Description
shares	uint256	Exact number of vault shares to mint (18 decimals).
receiver	address	Address that will receive the shares.

Returns

Name	Type	Description
assets	uint256	Amount of USDC pulled from the caller (6 decimals).

Preconditions

• depositsPaused() must be false.
• shares > 0.
• receiver must be a non-zero address.
• The caller must have approved at least the resulting assets of USDC to the vault. Quote the required amount with the read function previewMint(shares).

Events emitted

event Deposit(address indexed sender, address indexed owner, uint256 assets, uint256 shares);
event Transfer(address indexed from, address indexed to, uint256 value); // share mint

Example — mint 100 shares

import { parseUnits } from 'viem'
import { publicClient, walletClient } from './client'
import { liteUsdVaultAbi } from './abi'
import { VAULT, SHARE_DECIMALS } from './constants'

const account = walletClient.account!
const shares = parseUnits('100', SHARE_DECIMALS)

// Simulate first — `result` is the USDC amount the vault will pull.
// Make sure your USDC allowance to the vault is >= this value
// before calling writeContract. (See Getting Started.)
const { request, result: requiredAssets } = await publicClient.simulateContract({
  account,
  address: VAULT,
  abi: liteUsdVaultAbi,
  functionName: 'mint',
  args: [shares, account.address],
})

console.log('Will pull', requiredAssets, 'USDC (raw, 6 decimals)')

const hash = await walletClient.writeContract(request)
await publicClient.waitForTransactionReceipt({ hash })

When to use this vs deposit

Use deposit when you have an exact USDC amount in mind. Use mint when you need an exact share amount — for example, when matching a pre-quoted position or rebalancing to a target share count.
