This script helps you upload your validator's metadata and image to IPFS, then update the StakeManager contract on Polygon with the new metadata URI.

• Validator private key from file: ./test-chain-5/consensus/validator.key in your validator node installation directory.
• Polygon funds: Some $POL (MATIC) in the validator wallet

• Node.js: v18.20.x
• npm

1. Switch to Node 18

nvm use 18

2. Configure environment

   • Update the .env file in the project root
   • Set your Polygon RPC endpoint (or use the default public RPC provided)

3. Add your validator image

   • Place a PNG image (256×256px) in this directory alongside the script
   • Example: my-logo.png

4. Install dependencies

npm install

Run the updateValidatorInfo.js script with the following arguments:

node updateValidatorInfo.js <VALIDATOR_PRIVATE_KEY> "<VALIDATOR_NAME>" "<METADATA_JSON_OR_EMPTY>" <PATH_TO_VALIDATOR_IMAGE>

• <VALIDATOR_PRIVATE_KEY>: Your node's private key (hex string)
• <VALIDATOR_NAME>: A descriptive name for your validator (wrapped in quotes)
• <METADATA_JSON_OR_EMPTY>: Any additional metadata as a JSON string, or " " for none
• <PATH_TO_VALIDATOR_IMAGE>: Path to your 256×256 PNG image
