Run

1. Install and sync Minter Node

minter node

2. Install and sync Ethereum & BSC node

geth --http --http.addr "127.0.0.1" --http.port "8545"

3. Sync Minter Hub Node

# Download genesis
mkdir -p ~/.mhub2/config/
curl ... > ~/.mhub2/config/genesis.json

# Start and sync Minter Hub node
mhub2 start \
  --p2p.persistent_peers="..."

for testnet:

# Download genesis
mkdir -p ~/.mhub/config/
curl https://raw.githubusercontent.com/MinterTeam/mhub2/master/testnet/genesis.json > ~/.mhub2/config/genesis.json

# Start and sync Minter Hub node
mhub2 start \
  --p2p.persistent_peers="99d3c94add8faccdfe37aaa0e0a5889e1a06426a@46.101.215.17:26656"

4. Generate Hub account

mhub2 keys add validator1

• WARNING: save generated key
• Request some test HUB to your generated address

5. Create Hub validator

mhub2 tendermint show-validator # show validator's public key
mhub2 tx staking create-validator \
  --from=validator1 \
  --amount=1000000000000000000hub \
  --pubkey=<VALIDATOR PUBLIC KEY>  \
  --commission-max-change-rate="0.1" \
  --commission-max-rate="1" \
  --commission-rate="0.1" \
  --min-self-delegation="1" \
  --chain-id=mhub-mainnet-2 (mhub-testnet-11 for testnet)

• WARNING: save tendermint validator's key
• An important point: the validator is turned off if it does not commit data for a long time. You can turn in on again by sending an unjail transaction. Docs: mhub2 tx slashing unjail --help

6. Generate Minter & Ethereum keys

mhub-keys-generator

• WARNING: save generated keys
• Request some test ETH to your generated address

7. Register Ethereum keys

mhub2 query account <YOUR_ACCOUNT> # get account nonce

mhub-keys-generator make_delegate_sign <YOUR_ETH_PRIVATE_KEY> <YOUR_ACCOUNT> <YOUR_NONCE>

mhub2 tx mhub2 set-delegate-keys <VALADDR> <YOUR_ACCOUNT> <ETH_ADDR> <SIG> --from=...

8. Start services. You can set them up as services or run in different terminal screens.

• Start Hub ↔ Ethereum oracle.
