# 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)
```
