Node Operators Endpoint Mapping Contract

This is a contract used by node operators to register their node.

Projects when choosing a node operator will have to choose it from the registered nodes on the pNetwork DAO and then:

1. Check the node has an endpoint registered within this contract
2. Check the node attestation is valid

Deploy

Set the ETH_FROM and ETH_KEYSTORE_ACCOUNT with the deployer address and private key respectively into the .env file and run:

forge create --verify --rpc-url polygon  PNetworkV4Nodes

Note: the official contract has been deployed here https://polygonscan.com/address/0x228e705ad070def5072d283606d14dad7592377b with one of the pNetwork Association key 0x984D8222e11afA2C4F6493BaF8b1f157C11d2629.

Scripts

Initial setup

Before running scripts, you need to setup the forge keystores in order to interact with the contract:

cast wallet import <sender-keystore-alias> --interactive

Note: You'll be prompt to type the private-key and a password that you'll need to add later to the .env file.

Create the .env file

Create an .env file at the project's root:

ETH_FROM=<sender-address>
ETH_KEYSTORE_ACCOUNT=<sender-keystore-alias>
ETH_PASSWORD=<sender-keystore-password-file-path>
ENDPOINT=<url-to-polygon-node>

Execute commands

All the commands are send through forge script contained into the scripts/ folder. For instance, to set an endpoint use:

./PNetworkV4Nodes.sh 'setEndpoint(address,string)' <node-operator-contract-address> 'http://helloworld.com' --broadcast

Note: remove --broadcast if you want to just run a simulation of the call

In order to remove an endpoint, execute:

./PNetworkV4Nodes.sh 'removeEndpoint(address)' <node-operator-contract-address> --broadcast

If you want to check your endpoint, call

./PNetworkV4Nodes.sh 'getEndpoint(address)' <node-operator-contract-address> --broadcast

Or

./PNetworkV4Nodes.sh 'getEndpoint(address,address)' <node-operator-contract-address> <node-address> --broadcast
