Running a Polygon Node on a local environment will require us to do the following:

• Running a single local ethereum node at port 9545
  • Check out Matic Contract Repo which can be helpful in running an eth node with plasma contract deployed.
• Running a single Bor node at port 8545
• Running a single Heimdall node (default config are mentioned at ~/.heimdall/config,toml)

Setting up Heimdall locally:

• Clone the Heimdall Repo - https://github.com/maticnetwork/heimdall
• Build the binary of heimdall using make install. If it doesn't work, navigate to cmd/heimdall folder and run go build. This will generate a binary in the same directory. Save the location of binary in bash_profile
• Run heimdalld init which would generate a initialization JSON like so: { "chain_id": "heimdall-nzf7nw", "node_id": "705c8054c1b61bb3ffaaa2863d7b22f9aeb0b2da" }.
• The above command will also generate two config files for heimdall which are located at ~/.heimdall/config:
  • heimdall-config.toml
  • config.toml

Bor Repo: https://github.com/maticnetwork/bor

Run the heimdall

cd

make build network=local

make install network=local
heimdalld init
heimdalld start

Run the rest-server

heimdalld rest-server

Setup Bor

git clone https://github.com/

cd 
make bor-all
cp ~/home/go/bin/bor /usr/local/bin
bor --dev --datadir /tmp/bor --http --http.addr 127.0.0.1 --http.port 8545 --http.corsdomain '*' --http.vhosts "*" --http.api 'eth,net,web3,txpool'

We are not able to connecct heimdall with bor. nothing happens when we send tx on bor via metamask
