make start-local-blockchain

3. deploy the contract to local blockchain

make deploy-local

4. migrate abi to client-web

make migrate-client-web

5. set environment valiables for client-web

Create .env file in the client-web directory

cd client/web
touch .env

Set the address of the deployed contract on the localhost

REACT_APP_LOCAL_CONTRACT_ADDRESS=<deployed-contract-address-on-localhost>

6. start the client-web

make start-client-web

You can use dSNS on localhost:3000!!

How to deploy dSNS (to Mumbai; testnet of Polygon layer2 network)

1. set environmental variables for deploying settings

Create .env file

cd blockchain
touch .env

Set environmental variables

MUMBAI_URL=https://polygon-mumbai.g.alchemy.com/v2/<YOUR ALCHEMY KEY>
PRIVATE_KEY=abc123abc123abc123abc123abc123abc123abc123abc123abc123abc123abc1

• MUMBAI_URL: api endpoints of the infrastructure you are deploying to (e.g. Alchemy, infura, etc.)
  If you have not created it yet, click here.
• PRIVATE_KEY: your private key of the wallet (Never disclose this information to the public!!)

2. deploy the contract

Deployment costs gas, so you need to have some amount of MATIC in advance. mumbai's MATIC is distributed here

make deploy-mumbai
