rocketpool

name

rocketpool

description

Interact with Rocket Pool protocol contracts on Ethereum mainnet and Hoodi testnet. Use for any task involving rETH (liquid staking token), RPL (governance token), ETH staking, minting/burning rETH, checking exchange rates, node operator registration, minipool/megapool management, RPL staking, governance proposals, voting, rewards claiming, deposit pool queries, network balances, smoothing pool, or any Rocket Pool smart contract interaction. Supports both cast (Foundry CLI) and Ethereum MCP tools.

Rocket Pool Contracts

Quick Start

Query rETH Exchange Rate

cast call 0xae78736Cd615f374D3085123A210448E74Fc6393 "getExchangeRate()(uint256)" --rpc-url https://ethereum-rpc.publicnode.com

Deposit ETH to Mint rETH

cast send 0xCE15294273CFb9D9b628F4D61636623decDF4fdC "deposit()" --value 1ether --rpc-url $RPC_URL --private-key $PK

Check rETH Balance

cast call 0xae78736Cd615f374D3085123A210448E74Fc6393 "balanceOf(address)(uint256)" $WALLET --rpc-url https://ethereum-rpc.publicnode.com

Workflow

1. Look up the contract address from references/addresses.json
2. Find the function signature in the relevant domain reference file (see table below)
3. Use ABI files in assets/abis/<contractName>.json as a reference for function signatures and tuple layouts when needed
4. Execute via cast call (read) or cast send (write), or via MCP eth_call/eth_sendTransaction

For calls that involve complex types (for example tuples), use the ABI JSON to derive the exact signature:

cast call 0xCE15294273CFb9D9b628F4D61636623decDF4fdC "getBalance()(uint256)" --rpc-url $RPC_URL

Network Configuration

Network	Chain ID	RPC	rocketStorage
Mainnet	1	https://ethereum-rpc.publicnode.com	0x1d8f8f00cfa6758d7bE78336684788Fb0ee0Fa46
Hoodi	560048	https://rpc.hoodi.ethpandaops.io	0x594Fb75D3dc2DFa0150Ad03F99F97817747dd4E1

All contract addresses per network are in references/addresses.json.

Architecture

• RocketStorage is the central registry — all contracts resolve each other's addresses through it
• Contracts are upgradeable via governance: addresses in addresses.json reflect current deployments but can change
• To resolve an address dynamically:

  cast call $ROCKET_STORAGE "getAddress(bytes32)(address)" $(cast keccak "contract.addressrocketDepositPool") --rpc-url $RPC_URL
  

• Minipools (legacy): one contract per validator, 8 or 16 ETH bond
• Megapools (Saturn/v1.4): one contract per node, multiple validators, variable bond
• All ETH values are in wei (18 decimals); all percentages are 18-decimal fixed point (1e18 = 100%)

ABIs

ABI JSON files are bundled for most mainnet contracts in assets/abis/. The following contracts are signature-only in this skill (no bundled ABI): rocketNetworkRevenues, rocketDAOSecurityUpgrade, rocketMegapoolFactory, rocketMegapoolDelegate, rocketMegapoolManager, rocketMegapoolPenalties. Use these files as signature references for cast call / cast send:

cast call 0xae78736Cd615f374D3085123A210448E74Fc6393 "getExchangeRate()(uint256)" --rpc-url $RPC_URL
