string

ETH1 (execution client) node endpoint URL

--ssv-contract-address (-ca)

string

int

The cluster owner address (in the SSV contract)

--operator-ids (-oids)

string

Comma-separated list of operator IDs. The amount must be 3f+1 compatible.

Run

yarn cli cluster -n <ETH1_NODE_ENDPOINT_URL> -ca <SSV_CONTRACT_ADDRESS> -oa <CLUSTER_OWNER_ADDRESS> -oids <OPERATOR1_ID, OPERATOR2_ID, OPERATOR3_ID, OPERATOR4_ID>

Example:

Cluster snapshot:
┌─────────────────┬────────────────────────┐
│     (index)     │         Values         │
├─────────────────┼────────────────────────┤
│ validatorCount  │          '1'           │
│ networkFeeIndex │          '0'           │
│      index      │      '4647545440'      │
