Infura network support for sepollia in Brownie

Question

I have been trying to get testnet LINK for Goerli from chain.link. But it looks like it is no longer providing that for Goerli but Sepolia only. I am using the latest version of Brownie and it only has Goerli for Infura. So can you add manually Sepolia into the Brownie supported networks. On infura.io site, there is some info on network and URL.

Output from brownie networks list command:

Ethereum

Mainnet (Infura): mainnet

Ropsten (Infura): ropsten

Rinkeby (Infura): rinkeby

Goerli (Infura): goerli

Kovan (Infura): kovan

ganache-local: ganache-local

From infuro.io:

Network Description URL

Sepolia JSON-RPC over HTTPS https://sepolia.infura.io/v3/YOUR-API-KEY

Sepolia JSON-RPC over WebSocket wss://sepolia.infura.io/ws/v3/YOUR-API-KEY

Any suggestions?

Answer 1

Use this command in the terminal

brownie networks add Ethereum sepolia host="https://rpc.sepolia.dev" chainid=11155111

Answer 2

In the .brownie\network-config file:

Put this code into the section where other Infura networks are located.

  - chainid: 11155111
    explorer: https://api-sepolia.etherscan.io/api
    host: https://sepolia.infura.io/v3/$WEB3_INFURA_PROJECT_ID
    id: sepolia
    multicall2: '0x5BA1e12693Dc8F9c48aAD8770482f4739bEeD696'
    name: Sepolia (Infura)
    provider: infura

Answer 3

Use this command in the terminal

networks add Ethereum sepolia host="https://rpc.sepolia.org/" chainid=11155111

If following host is not working try changing the rpc host you can find hosts from this site : https://sepolia.dev/

Answer 4

brownie networks add Ethereum sepolia host=https://sepolia.infura.io/v3/$WEB3_INFURA_PROJECT_ID chainid=11155111 multicall2='0x5BA1e12693Dc8F9c48aAD8770482f4739bEeD696' explorer=https://api-sepolia.etherscan.io/api name="Sepolia (Infura)"

[SOLVED]

Adding the network to Brownie at the bottom works well, just make sure:

• in .env you have a variable called "WEB3_INFURA_PROJECT_ID"
• you do not overwrite the host in brownie-config.yaml.

Here is what I have in my brownie config for sepolia: sepolia: explorer: https://api-sepolia.etherscan.io/api keyhash(genesis hash): "0x25a5cc106eea7138acab33231d7160d69cb777ee0c2c553fcddf5138993e6dd9" eth_usd_price_feed: '0x694AA1769357215DE4FAC081bf1f309aDC325306'

Any News on this ? I'm trying to add Sepolia as well to Brownie networks but keep getting "HTTPError: 401 Client Error: Unauthorized for url: https://sepolia.infura.io/v3/" error.

I'm running the following command to add Sepolia to Brownie networks, and I do have the right WEB3_INFURA_PROJECT_ID set in my brownie-config.yaml.

brownie networks add Ethereum sepolia host=https://sepolia.infura.io/v3/$WEB3_INFURA_PROJECT_ID chainid=11155111 multicall2='0x5BA1e12693Dc8F9c48aAD8770482f4739bEeD696' explorer=https://api-sepolia.etherscan.io/api name="Sepolia (Infura)"

Answer 6

To add to the top upvoted answer, you can view all of the supported networks by typing brownie networks list.

The output you see comes from the network-config.yaml file located at ~/USERNAME/.brownie/network-config.yaml. If you add the following code to the network-config.yaml file and save it, you should see sepolia in the networks list:

- name: Sepolia (Infura)
  chainid: 11155111
  explorer: https://api-sepolia.etherscan.io/api
  host: https://sepolia.infura.io/v3/$WEB3_INFURA_PROJECT_ID
  id: sepolia
  multicall2: '0x5BA1e12693Dc8F9c48aAD8770482f4739bEeD696'
  provider: infura

To make sepolia the default chain that is used for your project, you can create a brownie-config.yaml file at the root of your project and set the default to sepolia.

networks:
    default: sepolia
