Registering as an Operator

​
Step 1: Get Whitelisted

To register, you must first be whitelisted as an operator. Please reach out to our team to request whitelisting.

​
Step 2: Call addStake

Once whitelisted, you can register by calling: 
addStake(bytes[] blsKeys)
  • blsKeys: Provide a list of your validator public keys.
  • You must also provide the required ETH collateral when calling.
Formatting Note for Etherscan: When providing bytes[] input on Etherscan, use the format: 
0xkey1,0xkey2,0xkey3,...
(No brackets, no quotes)

​
Stake Requirement

The parameter VanillaRegistry.minStake determines how much ETH must be staked per validator pubkey to opt-in to mev-commit:
  • Mainnet: 1 ETH (not live yet)
  • Hoodi: 0.0001 ETH

​
Withdrawing

If you need to deregister and withdraw:
  1. Call unstake(bytes[] blsKeys) to start the process. Validators are considered opted out during this time.
  2. Wait 96 blocks on Hoodi (the unstaking period).
  3. Call withdraw(bytes[] blsKeys) to receive your ETH back.
