Setting Up On-Chain Treasury Governance Protocols

On-chain treasury governance replaces opaque, multi-signature wallets with transparent, programmable rules for fund management. Protocols like OpenZeppelin Governor and Compound's Governor Bravo provide standardized frameworks. The core components are a treasury contract (e.g., using OpenZeppelin's TimelockController) that holds assets, and a governance contract that submits and executes proposals to move them. Setting this up involves deploying these contracts, configuring key parameters like voting delay and period, and connecting them to your governance token.

The first step is defining your governance parameters. These are critical security and operational settings baked into the contract upon deployment. Key values include:

• Voting Delay: The number of blocks between proposal submission and the start of voting.
• Voting Period: The duration (in blocks) that voting is open.
• Proposal Threshold: The minimum token balance required to submit a proposal.
• Quorum: The minimum percentage of the total token supply that must participate for a vote to be valid. For example, a common setup might use a 1-block voting delay, a 40,000-block (~7-day) voting period, a 1,000 token proposal threshold, and a 4% quorum.

Next, you deploy the core contracts. Using a framework like OpenZeppelin's Governor, the process involves writing and running a deployment script. Here's a simplified example using Hardhat and the @openzeppelin/contracts library:

solidityCopy
// Deploy a TimelockController with a 2-day delay
TimelockController timelock = new TimelockController(2 days, [], []);
// Deploy the Governor contract
MyGovernor governor = new MyGovernor(governanceToken, timelock);
// Grant the Governor the 'PROPOSER_ROLE' on the Timelock
timelock.grantRole(timelock.PROPOSER_ROLE(), address(governor));
// Grant the 'EXECUTOR_ROLE' to allow anyone to execute passed proposals
timelock.grantRole(timelock.EXECUTOR_ROLE(), address(0));

After deployment, the treasury's funds are transferred to the TimelockController address.

Finally, you must integrate the system with your front-end and community tools. The governance contract emits events for each proposal state change (ProposalCreated, VoteCast, ProposalExecuted), which should be indexed by a subgraph or backend service for display. Platforms like Tally or Boardroom can provide a pre-built user interface by connecting to your contract addresses. Ensure your community knows how to interact with the system: creating proposals requires calling propose(), voting uses castVote(), and successful proposals are queued and executed via the timelock after the delay.

Security considerations are paramount. Always use audited, battle-tested contract libraries from OpenZeppelin. The timelock delay is a critical defense, allowing token holders to review the calldata of a passed proposal before it executes. For high-value treasuries, consider a Security Council or Guardian role with the ability to veto malicious proposals in extreme cases, as seen in systems like Arbitrum. Thoroughly test all governance flows on a testnet (like Sepolia or Goerli) and conduct a time-locked mainnet deployment with progressively increased authority.

Setting up an on-chain treasury governance protocol requires a clear technical and operational foundation. The core prerequisites are a smart contract development environment (like Hardhat, Foundry, or Truffle), a blockchain node connection (via providers like Alchemy, Infura, or a local node), and a wallet with testnet funds for deployment. You must also have a solid understanding of the governance lifecycle, which includes proposal creation, voting, execution, and the timelock delay period that separates a vote's approval from its on-chain execution. This delay is a critical security feature.

The primary technical requirement is proficiency with a smart contract language, typically Solidity or Vyper. You will be working with, and often extending, standard governance contract interfaces like OpenZeppelin's Governor contracts. Familiarity with the ERC-20 token standard is essential, as your governance token will serve as the voting weight. For the setup, install Node.js (v18+ recommended) and your chosen development framework. Initialize a project and install dependencies, including the OpenZeppelin Contracts library: npm install @openzeppelin/contracts.

You must define your governance parameters before writing any code. These are immutable decisions that define your DAO's character. Key parameters include: voting delay (time between proposal submission and voting start), voting period (duration of the active vote), proposal threshold (minimum token balance to propose), and quorum (minimum participation required for a vote to be valid). For example, a common setup is a 1-block voting delay, a 3-day voting period, a 5% quorum, and a 2-day timelock. These values are set in the constructor of your custom Governor contract.

A secure setup mandates the use of a timelock controller. This contract acts as the sole executor of successful proposals, introducing a mandatory delay between vote completion and execution. This gives token holders a final window to react if a malicious proposal passes. In your system architecture, the timelock should hold the treasury funds and have ownership over any protocol contracts you wish to govern. Your Governor contract will be the only entity authorized to schedule and execute operations on the timelock, creating a clear, auditable permission chain from vote to action.

Finally, comprehensive testing is non-negotiable. Use a framework like Hardhat's test environment or Forge to simulate the entire governance flow. Write tests for: proposal creation with correct thresholds, voting with token weights, vote tallying and quorum calculation, the timelock delay period, and successful execution of proposal calldata. Test edge cases, such as failed proposals and attempts to bypass the timelock. Only after all tests pass and you have conducted a thorough review (or audit) should you proceed to deploy to a testnet for a final community trial before mainnet launch.

An on-chain treasury protocol is a system of smart contracts that holds and manages a pool of digital assets (like ETH, USDC, or governance tokens) according to predefined rules. The architecture typically separates concerns into distinct modules: a vault for asset custody, a governance module for proposal creation and voting, and an execution module to carry out approved transactions. This separation enhances security and upgradability. Popular foundational frameworks include OpenZeppelin's Governor contracts and Gnosis Safe's multi-signature wallet, which provide battle-tested templates for building custom solutions.

The data flow for a governance action begins with proposal creation. An authorized participant submits a transaction to the governance contract, specifying a target contract (e.g., the treasury vault), a calldata payload (the function to execute, like transfer(address,uint256)), and a description. This proposal is then subject to a voting period, where token holders or designated signers cast their votes. Voting power is often calculated via token snapshots to prevent manipulation, a mechanism known as vote delegation or using a checkpoint token like OpenZeppelin's ERC20Votes.

Once a proposal achieves the required quorum and majority (e.g., >50% approval), it enters a timelock period. This is a critical security feature that delays execution, giving the community time to react to a malicious proposal. After the delay, any account can trigger the execution of the proposal, which calls the predefined function on the target contract. For example, to transfer 1000 USDC from the treasury to a grant recipient, the execution would call vault.transfer(recipientAddress, 1000000000) (accounting for 6 decimals). This entire flow is transparent and immutable on the blockchain.

Key architectural decisions involve choosing between gas-optimized and flexible governance. A minimal Governor contract might bundle voting and execution, while a more complex system like Compound's Governor Bravo uses a separate Timelock contract and supports proposal queuing. Security considerations are paramount: always use proxy patterns (like Transparent or UUPS) for upgradability, implement multisig guardians for emergency pauses, and conduct thorough audits on all custom logic that interfaces with the treasury vault.

Snapshot is the leading platform for off-chain governance signaling, used by protocols like Uniswap, Aave, and Lido. It allows token holders to vote on proposals without paying gas fees, creating a low-friction environment for community discussion and consensus-building. Votes are signed cryptographically, and results are stored on IPFS and Arweave for verifiability. This step is critical for any on-chain treasury because it establishes a clear, transparent record of community sentiment before any funds are moved.

To begin, navigate to snapshot.org and connect your wallet. You must control the Ethereum Name Service (ENS) domain you wish to use for your governance space (e.g., daoname.eth). This domain becomes the public URL for your proposals. In your wallet, you will delegate signing authority to a specific address, which can be a personal wallet for testing or a Gnosis Safe multi-signature wallet for production use. This delegated address will create proposals and settings for the space.

The core configuration happens in the Settings tab of your new space. Key parameters include:

• Strategies: Define how voting power is calculated (e.g., erc20-balance-of, erc721-with-multiplier).
• Validation: Set rules for proposal creation (e.g., minimum token threshold).
• Voting System: Choose between single-choice voting, weighted voting, or quadratic voting.
• Plugins: Add functionalities like delegation (delegation) or proposal discussion forums. A basic erc20-balance-of strategy using your governance token's contract address is the most common starting point.

For advanced setups, you can write custom strategies in JavaScript to calculate voting power based on complex logic, such as time-locked tokens or cross-chain balances. The configuration is saved in a space.json file pinned to IPFS. Here is a minimal example of a space settings file referenced by your ENS domain:

jsonCopy
{
  "name": "My DAO",
  "strategies": [
    {
      "name": "erc20-balance-of",
      "params": {
        "address": "0x...",
        "symbol": "GOV",
        "decimals": 18
      }
    }
  ],
  "validation": {
    "name": "basic",
    "params": {
      "minScore": 10000
    }
  }
}

After configuration, test the space thoroughly. Create a dummy proposal and vote on it using different wallets to ensure voting power calculates correctly and the validation rules work as intended. The final, verified proposal outcomes from Snapshot provide the mandate that will be executed by the on-chain component, such as a SafeSnap module on a Gnosis Safe, which we will cover in the next step. Proper setup here prevents disputes during the critical on-chain execution phase.

Begin by deploying a new Gnosis Safe multisig wallet. This will serve as the secure treasury vault for your protocol's assets. You can deploy a new Safe directly via the Safe{Wallet} interface or programmatically using the @safe-global/safe-core-sdk. For a production treasury, a 2-of-3 or 3-of-5 signer configuration is a common starting point, balancing security with operational resilience. Ensure all signers are hardware wallets or secure smart contract accounts.

Once your Safe is active, you must connect it to the Zodiac ecosystem. Zodiac is a collection of modular tools that extend Safe's capabilities. The first critical module to install is the Zodiac Roles Modifier. This module enables role-based permissions, allowing you to define which addresses (e.g., a governance contract or a dedicated operator) can execute specific types of transactions from the Safe, such as token transfers or contract interactions.

After installing the Roles Modifier, you will configure its permissions. This involves defining target addresses (the contracts you want to interact with), function selectors (the specific functions allowed, like transfer), and assigning these permissions to role identifiers. For example, you could grant a "Treasury Manager" role the permission to call transfer on your project's ERC-20 token contract, but not to approve unlimited spends.

The next essential module is the Delay Modifier. This introduces a mandatory timelock between when a transaction is proposed and when it can be executed. This is a critical security feature, providing a final review period for signers to veto any malicious or erroneous proposal. A typical delay for a treasury might be set between 24 to 72 hours. The Delay Modifier is often stacked behind the Roles Modifier in the transaction execution flow.

Finally, you will connect your governance mechanism. If using a Snapshot-based off-chain voting system, you deploy and configure an Exit Module or a Reality Module (like the Reality.eth oracle). These modules allow off-chain vote results to trigger on-chain execution via the Safe. For on-chain governance (e.g., an OpenZeppelin Governor contract), the governor address itself would be granted a role via the Roles Modifier to execute transactions directly.

Test the entire setup thoroughly on a testnet like Sepolia or Goerli. Propose a dummy transaction through your governance flow, observe the timelock, and confirm execution. Verify that unauthorized actions are correctly blocked. Your treasury is now a programmable, securely governed on-chain entity, ready for asset management and protocol operations.

A custom proposal contract defines the executable logic for a governance action, such as transferring funds or upgrading a protocol. Unlike a simple text proposal, it encodes the target address, calldata, and value for an on-chain transaction that executes automatically upon successful vote. This pattern, used by protocols like Compound and Uniswap, minimizes human intervention and reduces execution risk. The contract must implement a standard interface, typically an execute() function, which the governance timelock or executor contract will call.

Start by inheriting from a base contract like OpenZeppelin's GovernorProposal.sol or a DAO framework's template (e.g., Aragon's Agreement). Your core contract structure needs several key components:

• Proposal Data: Structs to store the target, value, and calldata.
• State Tracking: Variables for lifecycle states (Pending, Active, Executed, Canceled).
• Permission Checks: Modifiers to restrict proposal creation and execution to authorized addresses (e.g., the governance token contract or a multisig).
• Execution Logic: The execute() function containing the low-level call to the target.

Here is a minimal Solidity example for a treasury transfer proposal:

solidityCopy
contract TransferProposal {
    address public target;
    uint256 public value;
    bytes public data;
    bool public executed;

    constructor(address _target, uint256 _value, bytes memory _data) {
        target = _target;
        value = _value;
        data = _data;
    }

    function execute() external {
        require(!executed, "Already executed");
        (bool success, ) = target.call{value: value}(data);
        require(success, "Execution failed");
        executed = true;
    }
}

This contract, once deployed with specific parameters, represents a single executable proposal.

For complex operations like contract upgrades or parameter changes, the calldata must be carefully constructed. Use libraries like @openzeppelin/hardhat-upgrades to generate upgrade calldata for Transparent or UUPS proxies. Always include safety checks within the execute() function, such as deadline expiration or a minimum treasury balance requirement, to prevent failed transactions. Consider emitting events for each state change (ProposalCreated, ProposalExecuted) to facilitate off-chain tracking and indexing by tools like The Graph.

Thoroughly test proposals on a forked mainnet or testnet before governance submission. Use a framework like Hardhat or Foundry to simulate the full lifecycle: deployment, a successful vote passing in the governance contract, passage through a timelock delay, and final execution. Test edge cases, including failed executions due to insufficient gas or reverted calls. Auditing is critical; consider engaging a firm like Trail of Bits or CertiK for high-value treasury contracts, as seen in major DAOs like MakerDAO and Arbitrum.

Finally, integrate your proposal contract with the broader governance system. The proposal's address is typically submitted to the governance module (e.g., an OpenZeppelin Governor contract) via a propose() function. Upon vote success, the governance executor will call your contract's execute() function. Document the exact steps for community members to create and submit proposals, specifying required parameters and any associated proposal deposits. Clear documentation, as provided by Compound's governance guide, is essential for decentralized participation.

Implementing on-chain treasury governance requires integrating several critical components: a multisig wallet or DAO framework for proposal execution, a voting mechanism (like token-weighted or quadratic voting), and secure asset management modules. The primary goal is to create a transparent, automated system where fund allocation is controlled by the collective will of token holders, recorded immutably on the blockchain. Successful deployment minimizes human intermediaries and establishes clear, auditable rules for treasury operations.

For ongoing maintenance, establish regular security practices. Conduct periodic smart contract audits for any upgraded logic, using firms like ChainSecurity or OpenZeppelin. Implement a bug bounty program on platforms like Immunefi to incentivize external scrutiny. Monitor treasury activity with dashboards from Dune Analytics or Nansen to track fund flows and proposal participation. It is also crucial to maintain an active community forum (e.g., Commonwealth or Discourse) for off-chain discussion before proposals are formalized on-chain.

To extend your protocol's capabilities, consider integrating advanced modules. Streaming payments via Sablier or Superfluid allow for gradual fund disbursement upon proposal approval. Cross-chain governance can be facilitated using platforms like Axelar or LayerZero to manage assets on multiple networks. For more complex decision-making, explore conviction voting or holographic consensus models. Always reference the latest documentation from your chosen framework, such as OpenZeppelin Governor or Compound's Governor Bravo, for implementation details.

The next step is to stress-test the governance system in a low-stakes environment. Deploy the entire suite of contracts to a testnet (like Sepolia or Goerli) and run through full governance cycles: proposal creation, voting, timelock execution, and treasury payout. Use this phase to calibrate parameters like voting delay, voting period, and proposal threshold based on simulated participation. Engage a small group of trusted community members in this dry run to identify UX friction points and security assumptions before mainnet launch.

Finally, remember that technology is only one pillar of effective governance. The legal structure around the treasury, clear communication channels, and a culture of informed participation are equally vital. The most robust smart contract system will fail without an engaged and educated community. Your work now shifts from pure development to stewardship—maintaining the system, educating users, and iterating based on decentralized feedback to ensure the treasury serves its intended purpose for the long term.
