## USDT and USDC transfers with at least 1 million

### Description

Get a QuickAlert when at least 1 million USDT or USDC is transferred.

This QuickAlert listens to the `Transfer` event of USDT and USDC.

Here's the event definition, `Transfer (index_topic_1 address from, index_topic_2 address to, uint256 value)`.

### Blockchain & Network

Ethereum Mainnet.

> **Note:** To support other EVM-compatible network, change the `tx_logs_address` to the **contract address** of USDT and USDC on that specific network.
>
> Also make sure to change the `tx_logs_data_int` to reflect the **number of decimals** in the USDT and USDC contract.

### Expression Values

- `0xdac17f958d2ee523a2206206994597c13d831ec7` contract address of **USDT** on **Ethereum Mainnet**
- `0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48` contract address of **USDC** on **Ethereum Mainnet**
- `0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef` Topic hash of **Transfer** event
- `^0x[0]{24}[a-fA-F0-9]{40}$` regex to validate wallet addresses.
- `''` to make sure tx_logs_topic3 is empty
- `1000000000000` at least **1 million**, including **6 decimals** for USDT and USDC

### Expression

```
(
tx_logs_address == '0xdac17f958d2ee523a2206206994597c13d831ec7' ||
tx_logs_address == '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48'
) &&
tx_logs_topic0 == '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef' &&
tx_logs_topic1 =~ '^0x[0]{24}[a-fa-f0-9]{40}$' &&
tx_logs_topic2 =~ '^0x[0]{24}[a-fa-f0-9]{40}$' &&
tx_logs_topic3 == '' &&
tx_logs_data_int >= 1000000000000
```

### Expected Result
