# Usage notes

#### Full Deposit Process (Ethers.js)

```javascript
import { ethers } from "ethers";
import brinkVaultAbi from "./BrinkVault.json";

const brinkVault = new ethers.Contract(brinkVaultAddress, brinkVaultAbi, signer);
const asset = new ethers.Contract(assetAddress, erc20Abi, signer);

const amount = ethers.parseUnits("100", 18);

// Step 1: Approve
await asset.approve(brinkVaultAddress, amount);

// Step 2: Deposit
const tx = await brinkVault.deposit(amount, await signer.getAddress());
await tx.wait();

// Step 3: Check balance
const shares = await brinkVault.balanceOf(await signer.getAddress());
console.log("Vault shares:", shares.toString());
```

#### Withdraw Tokens

const withdrawTx = await brinkVault.withdraw(amount, await signer.getAddress(), await signer.getAddress());
await withdrawTx.wait();
```
