Rocketpool Node Operations

Rocket Pool — Node Operations

Quick Start

Check Node Count

cast call 0xcf2d76A7499d3acB5A22ce83c027651e8d76e250 "getNodeCount()(uint256)" --rpc-url https://ethereum-rpc.publicnode.com

Check If Address Is Registered Node

cast call 0xcf2d76A7499d3acB5A22ce83c027651e8d76e250 "getNodeExists(address)(bool)" $NODE_ADDR --rpc-url https://ethereum-rpc.publicnode.com

Check Staked RPL

cast call 0xedFc7DCaE43fF954577a2875a9D805874490eE3E "getNodeStakedRPL(address)(uint256)" $NODE_ADDR --rpc-url https://ethereum-rpc.publicnode.com

Workflow

1. Look up the contract address from references/addresses.json
2. Find the function signature below
3. Load the ABI from assets/abis/<contractName>.json when available (Megapool contracts in this skill are signature-only)
4. Execute via cast call (read) or cast send (write)

Network Configuration

Architecture

• RocketStorage is the central registry — all contracts resolve each other's addresses through it
• Minipools (legacy): one contract per validator, 8 or 16 ETH bond
• Megapools (Saturn/v1.4): one contract per node, multiple validators, variable bond
• Deploy megapool via rocketNodeManager.deployMegapool(), not the factory directly
• All ETH values are in wei (18 decimals); all percentages are 18-decimal fixed point (1e18 = 100%)

Megapool Contracts (Saturn)

Megapools replace minipools as the new validator structure. A single megapool contract per node can manage multiple validators. No ABI files are bundled for rocketMegapoolFactory, rocketMegapoolDelegate, rocketMegapoolManager, rocketMegapoolPenalties, or rocketMegapoolProxy in this skill. Use the raw signatures below with cast.

rocketMegapoolFactory

deployContract(address _nodeAddress) → address
getExpectedAddress(address _nodeAddress) → address [view]
getMegapoolDeployed(address _nodeAddress) → bool [view]

rocketMegapoolDelegate (per-megapool logic)

newValidator(uint256 _bondAmount, bool _useExpressTicket, bytes _validatorPubkey, bytes _validatorSignature, bytes32 _depositDataRoot)

Gotchas

• Deploy megapool via rocketNodeManager.deployMegapool(), not the factory directly
• Each node has exactly one megapool address, but can have multiple validators within it
• Bond reduction has a waiting period and can be cancelled by the oDAO
