## EAS Attestation Event

### Description

Get a QuickAlert when a specific EAS schema attestation is emitted

This QuickAlert listens to the `Attested` event from EAS and can be filtered to a specific schema.

Here's the event definition, `Attested (index_topic_1 address recipient, index_topic_2 address attester, bytes32 uid, index_topic_3 bytes32 schema)`.

### Blockchain & Network

Ethereum Mainnet.
Optimism Mainnet.

> **Note:** To support other EVM-compatible network, change the `tx_logs_address` to the **contract address** of EAS 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

- `0x4200000000000000000000000000000000000021` contract address of **EAS** on **Optimism Mainnet**
- `0xA1207F3BBa224E2c9c3c6D5aF63D0eb1582Ce587` contract address of **EAS** on **Ethereum Mainnet**
- `0x8bf46bf4cfd674fa735a3d63ec1c9ad4153f033c290341f3a588b75685141b35` Topic hash of **Attested** event

### Expression

```
tx_logs_address == '0x4200000000000000000000000000000000000021' &&
tx_logs_topic0 == '0x8bf46bf4cfd674fa735a3d63ec1c9ad4153f033c290341f3a588b75685141b35'
```
Optionally you can filter by a specific schema
```
... &&
tx_logs_topic3 == SPECIFIC_SCHEMA_UID
```

### Expected Result

```
