Setting Up a Treasury Advisory Board with On-Chain Mandate

A Treasury Advisory Board (TAB) is a specialized committee responsible for providing strategic guidance on a protocol's treasury management. Unlike traditional boards, a TAB's authority and operational rules can be encoded directly into smart contracts, creating a transparent and tamper-proof governance layer. This on-chain mandate ensures that the board's actions—from proposing investment strategies to executing transactions—are publicly verifiable and bound by pre-defined rules, reducing reliance on opaque, off-chain processes.

The core components of an on-chain TAB mandate include its composition, proposal authority, voting mechanics, and execution permissions. For example, a mandate might specify that the board consists of five members, requires a 4/5 multi-signature wallet (like a Safe) to approve transactions over $100k, and uses a Snapshot space for off-chain signaling on broader strategy. These rules are deployed as immutable contracts or configured within existing treasury management platforms such as Llama or Syndicate.

Setting up the mandate begins with defining the board's purpose in a clear scope of work document. Common responsibilities include asset diversification, risk assessment for DeFi yield strategies, budgeting for grants programs, and managing operational expenses. This document should be ratified by the DAO's broader tokenholder governance, often via a Temperature Check or Consensus Check vote, before any technical implementation begins.

Technically, implementation involves deploying the smart contracts that enforce the board's rules. A typical setup uses a multi-signature wallet as the execution vehicle, with its signer set and threshold defined by the mandate. More advanced setups might use a module within a DAO framework like Aragon OSx or a custom Governor contract that allows the TAB to create proposals that are then ratified by a timelock and executor. The key is that all permissions are visible on-chain.

For ongoing operations, the TAB's activity should be fully transparent. All proposals, discussions (which can occur on forums like Commonwealth or Discourse), and on-chain votes should be publicly accessible. Tools like DeepDAO or Tally can be used to track the board's proposal history and treasury movements. This transparency is critical for maintaining trust with the broader community and serves as a real-time audit trail.

Ultimately, an on-chain TAB moves treasury governance from subjective, informal guidance to objective, programmatic execution. It provides a clear framework for expert stewardship while ensuring the community retains ultimate sovereignty. By following this guide, projects can build a resilient structure that protects assets and aligns long-term financial strategy with protocol goals.

Establishing a Treasury Advisory Board (TAB) with an on-chain mandate requires a clear governance framework. This starts with a formal charter, ratified by your DAO or core team, that defines the board's purpose, scope of authority, and reporting lines. The charter should specify key parameters such as the board's composition (e.g., 3-7 members), member selection process (e.g., community vote, core team appointment), term limits, and compensation structure. This document serves as the legal and operational bedrock, ensuring all stakeholders understand the board's role before any code is written.

The technical prerequisite is a secure, multi-signature (multisig) wallet that will serve as the board's operational treasury. For Ethereum-based organizations, Gnosis Safe is the industry standard, but alternatives like Safe{Wallet} on other EVM chains or Squads on Solana are also viable. This wallet's signers should be the appointed board members. The multisig threshold—the number of signatures required to execute a transaction—must be carefully calibrated (e.g., 3-of-5) to balance security with operational efficiency. This wallet address will be the target for the on-chain mandate's permissions.

You must also decide on the blockchain and the specific smart contract framework for encoding the mandate. For maximum security and composability, many projects use Ethereum or an EVM-compatible Layer 2 like Arbitrum or Optimism. The mandate itself can be implemented using custom access control logic within your existing treasury management contracts, or via a dedicated policy engine like OpenZeppelin Defender for rule-based automation or Syndicate for transaction framing. The choice depends on the complexity of the spending rules you intend to enforce.

Finally, ensure all board members possess the necessary operational knowledge. This includes familiarity with using the chosen multisig wallet interface, understanding basic transaction signing (gas fees, nonces), and recognizing common security threats like phishing. For advanced mandates involving DeFi operations, members should understand concepts like slippage, liquidity pools, and oracle prices. Providing documented runbooks and conducting a dry-run with testnet funds are critical steps to prevent costly errors when the system goes live on mainnet.

An on-chain advisory mandate is a set of encoded rules that defines the scope, authority, and operational procedures for a treasury advisory board. Unlike traditional paper-based charters, this mandate is deployed as a smart contract on a blockchain, making it immutable, transparent, and automatically executable. Key components typically include the board's composition (e.g., number of members, required expertise), proposal submission processes, voting mechanisms for recommendations, and clear delineation between advisory power and executive authority held by a DAO's core team or multisig. This creates a verifiable public record of the board's intended function.

Setting up this structure begins with drafting the mandate's legal and operational terms off-chain. The critical technical step is translating these rules into smart contract logic. For example, a contract might enforce that only wallet addresses whitelisted as boardMembers can create Proposal structs. It could mandate a minimum quorum of members and a passingThreshold (e.g., 4 of 7 votes) for a recommendation to be formally recorded on-chain. Using a framework like OpenZeppelin's Governor or Aragon OSx can accelerate development by providing modular, audited components for voting and access control.

The primary advantage is enhanced trust and accountability. All stakeholders can audit the board's rules and its activity history directly from the blockchain. For instance, a community can verify that a costly investment recommendation truly achieved the required supermajority vote. Furthermore, the mandate can programmatically trigger downstream actions. A successful advisory vote could generate an event that automatically creates a formal treasury management proposal in the DAO's main governance system, streamlining workflow. This reduces ambiguity and prevents mission creep by the advisory body.

Consider a DAO with a $50M treasury wanting to manage risk. Its on-chain mandate for a Financial Advisory Board might specify: 5 members, a 7-day voting period on the Optimism network, and a 60% approval threshold. A code snippet for a simplified voting checkpoint might look like:

solidityCopy
function voteOnRecommendation(uint proposalId, bool support) external onlyBoardMember {
    Proposal storage p = proposals[proposalId];
    require(block.timestamp <= p.votingDeadline, "Voting closed");
    // ... record vote logic
    if (votesFor >= (totalBoardMembers * 60) / 100) {
        p.executed = true;
        emit RecommendationApproved(proposalId);
    }
}

This transparent mechanism ensures the board's output is credible and binding according to pre-set rules.

Implementing an on-chain mandate requires careful design to avoid rigidity. Smart contracts are difficult to modify, so the mandate should focus on core procedural invariants while leaving operational details to an off-chain handbook. It's also crucial to integrate the advisory board's output with the DAO's existing governance, such as having the on-chain approval event serve as a prerequisite for a Snapshot vote or a Safe multisig transaction. By codifying the advisory process, DAOs can professionalize treasury management while maintaining the decentralized, verifiable ethos of blockchain governance.

The core of an on-chain Treasury Advisory Board is a smart contract that defines the board's membership, proposal lifecycle, and execution logic. We'll use a modular approach, separating the voting token (often an ERC-20 or ERC-1155), the governor contract (e.g., OpenZeppelin's Governor), and the Treasury contract (e.g., OpenZeppelin's TimelockController). The mandate is encoded directly into the proposal and execution logic, ensuring all actions are permissioned and transparent. Start by defining the board's parameters: votingDelay, votingPeriod, proposalThreshold, and quorum.

First, deploy the voting token that represents board membership. This could be a non-transferable ERC-1155 NFT where each unique token ID represents a board seat, granting one vote. Alternatively, use a weighted ERC-20 token where balances represent voting power, allowing for senior or lead advisor roles. The constructor mints tokens to the initial set of advisors. Here's a basic example of a non-transferable membership token:

solidityCopy
import "@openzeppelin/contracts/token/ERC1155/ERC1155.sol";
contract AdvisoryToken is ERC1155 {
    address public admin;
    constructor(address[] memory initialAdvisors) ERC1155("") {
        admin = msg.sender;
        for (uint i = 0; i < initialAdvisors.length; i++) {
            _mint(initialAdvisors[i], i, 1, ""); // Mint seat ID i
        }
    }
    function _beforeTokenTransfer(...) internal override {
        revert("NonTransferable"); // Lock tokens in wallet
    }
}

Next, set up the governance and treasury execution contracts. Use OpenZeppelin Governor with a custom voting module that reads from your AdvisoryToken. The TreasuryTimelock contract holds the DAO's assets and executes successful proposals after a delay. The key integration is in the governor's _execute function, which calls the timelock. Proposals are limited to pre-defined target addresses and function selectors that align with the board's on-chain mandate (e.g., only interacting with specific DeFi protocols or custody solutions).

The proposal lifecycle is critical. A typical flow is: 1) Propose: An advisor submits a transaction list (target, value, calldata). 2) Vote: Token holders cast votes within the votingPeriod. 3) Queue: If quorum and majority are met, the proposal is queued in the TreasuryTimelock. 4) Execute: After the timelock delay (e.g., 48 hours for review), anyone can trigger execution. This delay is a key security feature, allowing for last-minute cancellation if a proposal is malicious. Use OpenZeppelin's Governor contracts to inherit this standard logic securely.

To enforce the mandate, implement proposal validation. Create a MandateChecker contract or modifier that validates proposal calldata against a whitelist of allowed functions. For example, the mandate may only permit calls to swap() on a specific DEX, deposit() into a named yield vault, or transfer() to a multisig. Failed validation should revert the proposal creation. This on-chain rule set ensures the board cannot deviate from its predefined operational scope, providing accountability to the broader DAO.

Finally, integrate with front-end tools like Tally or Boardroom for user-friendly proposal creation and voting. Use the OpenZeppelin Defender for admin tasks and proposal automation. Remember to conduct thorough testing and audits on a testnet (like Sepolia) before mainnet deployment. The complete code, along with deployment scripts using Hardhat or Foundry, can be found in the Chainscore Labs GitHub repository.

To ensure your Treasury Advisory Board is operational, complete this implementation checklist. First, finalize the governance proposal with clear specifications: the board's size (e.g., 3-7 members), term lengths (e.g., 1 year), and compensation structure (e.g., a flat ETH/USDC stipend per quarter). Second, deploy the required smart contracts. This includes the TABRegistry for member management, a MultisigWallet (like Safe) for fund custody, and any custom Vesting or Streaming contracts for compensation. Third, conduct the inaugural election using your DAO's existing Snapshot and Governor Bravo-compatible voting system to seat the first members.

With the board operational, the next phase involves optimizing its processes and reporting. Establish a regular cadence for reviews, such as quarterly portfolio assessments against the mandate's risk parameters. Implement on-chain reporting by having the board publish key metrics—like treasury asset allocation, performance against benchmarks, and executed transactions—to a public forum or a dedicated dashboard like Llama. This transparency builds trust with the DAO community and provides verifiable data for performance evaluation. Consider using tools like OpenZeppelin Defender to automate and secure recurring administrative tasks, such as processing compensation streams.

For projects seeking more sophisticated control, explore advanced mandate structures. Instead of a simple multisig, implement a module-based architecture within your Safe wallet. This allows you to add a Zodiac Module that enforces rules, such as requiring a positive on-chain vote from a token-weighted governance contract for any transaction over a certain threshold. You can also integrate DeFi risk monitoring services like Gauntlet or Chaos Labs to provide the TAB with real-time alerts on protocol exposures, moving beyond static allocation limits to dynamic risk management.

The final step is continuous iteration. Governance is not set-and-forget. After each board term, propose amendments to the on-chain mandate based on performance reviews and changing market conditions. Use forum discussions and temperature checks to gauge community sentiment on adjustments to investment strategies or risk tolerance. By treating the TAB framework as upgradeable code, your DAO can systematically improve its treasury management, turning a defensive asset holding into a strategic engine for sustainable growth.
