git clone https://github.com/airchains-network/evm-station.git
git clone https://github.com/airchains-network/tracks.git

2. Setting Up and Running the EVM Station:

cd evm-station

go mod tidy

/bin/bash ./scripts/local-setup.sh
/bin/bash ./scripts/local-start.sh 

Get Your Private Key of EVM Station

/bin/bash ./scripts/local-keys.sh

Result:

⚡ root@vmi1797354  ~/evm-station   master ±  /bin/bash ./scripts/local-keys.sh

Save private key to import MetaMask Wallet

3. Setting Up DA Keys and Running DA Client: (Eigen)

wget https://github.com/airchains-network/tracks/releases/download/v0.0.2/eigenlayer

Create and List Keys:

./eigenlayer operator keys create --key-type ecdsa [keyname]

Result:

eigenlayer operator keys create --key-type ecdsa test
? Enter password to encrypt the ecdsa private key:
ECDSA Private Key (Hex):  b3eba201405d5b5f7aaa9adf6bb734dc6c0f448ef64dd39df80ca2d92fca6d7b
Please backup the above private key hex in safe place.

Key location: /home/ubuntu/.eigenlayer/operator_keys/test.ecdsa.key.json
Public Key hex:  f87ee475109c2943038b3c006b8a004ee17bebf3357d10d8f63ef202c5c28723906533dccfda5d76c1da0a9f05cc6d32085ca1af8aaab5a28171474b1ad0aa68

Remember this PUB_KEY

4. Setting Up and Running Tracks:

Open new tmux tab

sudo rm -rf ~/.tracks

cd tracks

go mod tidy

Initiate Sequencer:

go run cmd/main.go init --daRpc "da-rpc" --daKey "daKey" --daType "<da-type>" --moniker "<moniker-name>" --stationRpc "http://127.0.0.1:8545" --stationAPI "http://127.0.0.1:8545" --stationType "evm"

• --daRpc: "disperser-holesky.eigenda.xyz"

• --daKey: <PUB KEY of DA key>

• --daType: "eigen"

• --moniker: "moniker name"

Sample:

go run cmd/main.go init --daRpc "disperser-holesky.eigenda.xyz" --daKey "6a822c60ca15c81e824df6c2ff83f050224473bcbaabccab2d8ac084a7749fbb745c3ae96c0b3964083409c39d074cb6000ddb8b093ca3e98bde7c78f794267e" --daType "eigen" --moniker "JosephTran" --stationRpc "http://0.0.0.0:8545" --stationAPI "http://0.0.0.0:8545" --stationType "evm"

Create Keys for Junction:

Generate keys for the Junction component using the following command:

go run cmd/main.go keys junction --accountName <account-name> --accountPath $HOME/.tracks/junction-accounts/keys

Replace <account-name>

Sample:

go run cmd/main.go keys junction --accountName josephtran --accountPath $HOME/.tracks/junction-accounts/keys

Result:

Start Node:

go run cmd/main.go start

Add Wallet and your network to Meta mask:

Use private key which created by /bin/bash ./scripts/local-keys.sh

Add Network:

Open EVM RPC port to connect from Client:

nano /root/.evmosd/config/app.toml

###############################################################################
###                           JSON RPC Configuration                        ###

[json-rpc]

# Enable defines if the gRPC server should be enabled.
enable = true

# Address defines the EVM RPC HTTP server address to bind to.
address = "0.0.0.0:8545"

Restart EVM Station:

/bin/bash ./scripts/local-start.sh 

Add wallet from Client:

*Chain ID will auto get after input URL network:
