MultiVault

Multi-signature treasury protocol for DAOs on Base. Manage multiple independent vaults with weighted approvals and programmable payouts.

Overview

MultiVault enables DAOs and teams to create isolated treasury vaults with customizable governance. Each vault maintains its own signers, voting weights, and approval thresholds.

Documentation

• Vault Model Specification - Comprehensive technical documentation covering vault lifecycle, data model, configuration rules, and integration guidelines for developers and auditors
• Role System Design - Complete role hierarchy, access control matrix, and privilege escalation protection mechanisms
• Governance Patterns - Recommended governance configurations for DAOs, companies, and hybrid organizations

Key Features

• Multiple Vaults: Create unlimited independent treasuries
• Weighted Voting: Assign different voting power to signers
• Flexible Thresholds: Set custom approval requirements per vault
• Programmable Payouts: One-time, vesting, and streaming payments
• USDC Transfers: Native Base Pay integration
• Role-Based Access Control: Granular permissions with GLOBAL_ADMIN, VAULT_ADMIN, OPERATOR, and PAUSER roles
• Emergency Pause: Circuit breaker for security incidents
• Fully Upgradeable: UUPS proxy pattern with safe storage layout

Use Cases

DAO Treasury Management

// Create DAO treasury vault
uint256 daoVault = multiVault.createVault(
    "DAO Treasury",
    "ipfs://QmMetadata..."
);

// Add council members with weights
multiVault.addSigner(daoVault, member1, 100);  // 100 votes
multiVault.addSigner(daoVault, member2, 150);  // 150 votes
multiVault.addSigner(daoVault, member3, 200);  // 200 votes

// Set threshold (need 300+ votes to execute)
multiVault.setThreshold(daoVault, 300);

Multi-Department Budgets

// Separate vaults for different teams
uint256 devFund = multiVault.createVault("Development", "ipfs://...");
uint256 marketingFund = multiVault.createVault("Marketing", "ipfs://...");
uint256 grantsFund = multiVault.createVault("Grants", "ipfs://...");

// Each vault has independent signers and rules

Contributor Payroll

// Create proposal for payment
uint256 proposalId = multiVault.createProposal(
    contributor,
    5000 * 1e6,  // 5000 USDC
    USDC_ADDRESS,
    ""
);

// Signers approve
multiVault.approveProposal(proposalId);

// Execute when threshold met
multiVault.executeProposal(proposalId);
