### Quick Start with OfframpClient Initialization and Operations

Source: https://github.com/zkp2p/zkp2p-client-sdk/blob/main/README.md

Demonstrates how to initialize the OfframpClient with a wallet client and chain configuration, and perform common operations such as querying deposits and intents, creating new deposits, and using the advanced indexer. It utilizes viem for wallet management and the Offramp SDK for blockchain interactions.

```typescript
import { OfframpClient, Currency } from '@zkp2p/offramp-sdk';
import { createWalletClient, custom } from 'viem';
import { base } from 'viem/chains';

const walletClient = createWalletClient({
  chain: base,
  transport: custom(window.ethereum),
});

const client = new OfframpClient({
  walletClient,
  chainId: base.id,
  apiKey: 'YOUR_API_KEY',
});

// Query deposits (RPC - instant, real-time)
const deposits = await client.getDeposits();
const deposit = await client.getDeposit(42n);

// Query intents (RPC - instant, real-time)
const intents = await client.getIntents();

// Create a deposit to provide liquidity
await client.createDeposit({
  token: '0xUSDC',
  amount: 10000000000n,
  intentAmountRange: { min: 100000n, max: 1000000000n },
  processorNames: ['wise', 'revolut'],
  depositData: [{ email: 'maker@example.com' }, { tag: '@maker' }],

```typescript
const tierInfo = await client.getTakerTier({
  owner: '0xUserAddress',
  chainId: 8453
