# @elizaos/plugin-goldrush
2+
3+
A plugin for ElizaOS that integrates Covalent's GoldRush SDK for cross-chain wallet monitoring.
4+
5+
## Features
6+
7+
- Cross-chain wallet balance tracking (in chain's native currency)
8+
- Basic transaction history (last 10 transactions)
9+
- Support for multiple chains:
10+
- Ethereum
11+
- Solana
12+
- Algorand
13+
- Aptos
14+
- Cosmos
15+
- Tron
16+
- Comprehensive error handling and logging
17+
18+
## Installation
19+
20+
```bash
21+
pnpm add @elizaos/plugin-goldrush
22+
```
23+
24+
## Configuration
25+
26+
1. Get a Covalent API key from [Covalent](https://www.covalenthq.com/platform/auth/register/)
27+
28+
2. Add your API key to your ElizaOS environment:
29+
30+
```bash
31+
# .env file
32+
COVALENT_API_KEY=your_api_key_here
33+
```
34+
35+
3. Add the plugin to your ElizaOS configuration:
36+
37+
```typescript
38+
import { goldrushPlugin } from "@elizaos/plugin-goldrush";
39+
40+
// The plugin will be automatically loaded if COVALENT_API_KEY is present
41+
const config = {
42+
plugins: [goldrushPlugin],
43+
};
44+
```
45+
46+
## Usage
47+
48+
The plugin provides a provider that can be used to fetch wallet data:
49+
50+
```typescript
51+
try {
52+
// Get wallet data - note that runtime parameter is required
53+
const result = await runtime.providers.goldrush.get(runtime, {
54+
address: "0x123...",
55+
chain: "eth-mainnet" // Optional, defaults to eth-mainnet
56+
});
57+
58+
// The result includes:
59+
{
60+
address: string; // The wallet address
61+
balance: string; // Balance in chain's native currency (e.g., ETH for Ethereum)
62+
transactions: string[]; // Array of transaction hashes (up to 10 most recent)
63+
lastUpdated: number; // Timestamp of when the data was fetched
64+
}
65+
} catch (error) {
66+
// Handle specific error cases
67+
if (error.message.includes("Invalid Ethereum address")) {
68+
console.error("The provided address is not a valid Ethereum address");
69+
} else if (error.message.includes("Unsupported chain")) {
70+
console.error("The specified blockchain is not supported");
71+
} else if (error.message.includes("Invalid API key")) {
72+
console.error("Please check your Covalent API key configuration");
73+
} else {
74+
console.error("An error occurred while fetching wallet data:", error);
75+
}
76+
}
77+
```
78+
79+
## Supported Chains
80+
81+
- eth-mainnet (Ethereum Mainnet)
82+
- solana-mainnet
83+
- algorand-mainnet
84+
- aptos-mainnet
85+
- cosmos-mainnet
86+
- tron-mainnet
87+
88+
## Error Messages
89+
90+
The provider may throw the following errors:
91+
92+
- `"Covalent API key is required"` - When initializing without an API key
93+
- `"Invalid API key"` - When the provided API key is invalid
94+
- `"Wallet address is required"` - When calling get() without an address
95+
- `"Invalid Ethereum address format"` - When the address doesn't match the expected format
96+
- `"Unsupported chain: {chain}"` - When the specified chain is not supported
97+
- `"Failed to fetch wallet balances"` - When the Covalent API request fails
98+
- `"An unknown error occurred while fetching wallet data"` - For unexpected errors
99+
100+
## Error Handling
101+
102+
The provider includes error handling for common scenarios:
103+
104+
- Invalid API key validation on initialization
105+
- Invalid wallet address format checking
106+
- Unsupported chain validation
107+
- Network error handling with appropriate error messages
108+
- Graceful handling of failed transaction fetches (continues with empty array)
