# Update Validator Info

## **Config File**

Create a config file in JSON format that contains the following parameters (you can also leave parameters empty):

```
{  "name": "VALIDATOR_NAME", /* Name of the validator */
  "logoUrl": "LOGO_URL", /* Validator logo (PNG|JPEG|SVG) - 100px x 100px is enough */
  "website": "WEBSITE_URL", /* Website icon on the right */
  "contact": "CONTACT_URL" /* Contact icon on the right */
}
```

Example:

```
{
  "name": "any",
  "logoUrl": "https://any.site/vinu/any.png",
  "website": "https://any.site",
  "contact": "https://t.me/any_vinu"
}
```

Then host it somewhere publicly accessible.

## **Update your info in the smart contract**

1. Connect to your validator node
2. Open up a go-opera console session via `go-opera attach`
3. Load the `stakerInfoContract ABI` and instantiate the contract:

```
abi = JSON.parse('[{"inputs":[{"internalType":"address","name":"_stakerContractAddress","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":false,"internalType":"uint256","name":"stakerID","type":"uint256"}],"name":"InfoUpdated","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"internalType":"address","name":"previousOwner","type":"address"},{"indexed":true,"internalType":"address","name":"newOwner","type":"address"}],"name":"OwnershipTransferred","type":"event"},{"constant":true,"inputs":[],"name":"isOwner","outputs":[{"internalType":"bool","name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"internalType":"address","name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"renounceOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"internalType":"uint256","name":"","type":"uint256"}],"name":"stakerInfos","outputs":[{"internalType":"string","name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"internalType":"address","name":"newOwner","type":"address"}],"name":"transferOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"internalType":"address","name":"_stakerContractAddress","type":"address"}],"name":"updateStakerContractAddress","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"internalType":"string","name":"_configUrl","type":"string"}],"name":"updateInfo","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"internalType":"uint256","name":"_stakerID","type":"uint256"}],"name":"getInfo","outputs":[{"internalType":"string","name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}]')
```

**Mainnet:**

```
stakerInfoContract = web3.vc.contract(abi).at("0xb914a0b16111BaB228ae6214e6E1FD4a5EaE877C")
```

**Testnet:**

```
stakerInfoContract = web3.vc.contract(abi).at("0x6b39bcd174DddF5A17d065822BDC43353eB6112A")
```

4. Unlock validator account

```
# Unlock validator wallet
personal.unlockAccount("VALIDATOR_WALLET_ADDRESS", "PASSWORD", 300)
```

5. Call the `updateInfo` function of the `stakerInfoContract` (make sure you have enough VC on your wallet to cover the transaction fee)

```
stakerInfoContract.updateInfo("CONFIG_URL", 
{ from: "VALIDATOR_ADDRESS" })
```

Example:

```
stakerInfoContract.updateInfo("https://any.site/vinu/config.json", 
{ from: "VALIDATOR_WALLET_ADDRESS" })
```

6. Validate if you updated your info correctly

```
stakerInfoContract.getInfo(STAKER_ID)
```

Example:

```
stakerInfoContract.getInfo(14)
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://vinu.gitbook.io/vinuchain/technical-docs/nodes-and-validators/update-validator-info.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
