Mechanism

Co-Proposer Registration

struct CoProposer {
    address agent;      // Co-proposer address (must be registered agent)
    uint256 splitBps;   // Share of performance fee in basis points
}

propose(
    vault,                // target vault
    strategy,             // Lane A live-NAV source: positions() priced by the PriceRouter; address(0) = Lane B (async queue) only
    metadataURI,
    strategyDuration,
    executeCalls,
    settlementCalls,
    coProposers: [
        { agent: agentB, splitBps: 3000 },  // 30%
        { agent: agentC, splitBps: 1000 },  // 10%
    ]
)

​

Validation Rules

1. The sum of co-proposer splits must be ≤ 9000 BPS (≤ 90%). The lead proposer’s split is not passed in — it is derived as 10000 - totalCoSplitBps at validation time. So the lead automatically gets the remainder (≥ 10%). A co-split total above 9000 reverts with LeadSplitTooLow.
2. All co-proposers must be registered agents in the vault (ISyndicateVault.isAgent()).
3. No duplicate addresses. Lead proposer cannot appear in the co-proposers array, and co-proposers cannot repeat.
4. Minimum split: 100 BPS (1%). Prevents dust splits that waste gas on settlement (enforced via MIN_SPLIT_BPS).
5. Maximum co-proposers: the governor enforces a hard ceiling of ABSOLUTE_MAX_CO_PROPOSERS = 10, and the runtime maxCoProposers parameter gates the currently-allowed value. It is a per-vault parameter: the vault owner sets it via setMaxCoProposers (onlyVaultOwner, frozen while a proposal is open, bounds 1–10), and a new vault defaults to 10. Raising the ABSOLUTE_MAX_CO_PROPOSERS = 10 hard ceiling itself would require a governor impl upgrade via the shared GovernorBeacon. (Lead + maxCoProposers = total recipients at settlement.)
6. Lead proposer retains at least 1000 BPS (10%) — via rule #1, since totalCoSplitBps ≤ 9000.

​

Co-Proposer Consent

• Simpler — no EIP-712 typed data or signature aggregation needed
• Transparent — voters can verify all agents explicitly approved
• Auditable — consent is an on-chain event, not an off-chain blob
• Agents are already on-chain actors (registered wallet addresses) — calling a function is trivial

​

Lifecycle Changes

Solo:          Pending → Approved → Executed → Settled
Collaborative: Draft → Pending → Approved → Executed → Settled
                 ↓         (after all co-proposers approve)
              Cancelled   (if any reject or window expires)

​

Settlement Fee Distribution

Total profit: $10,000
Performance fee (20%): $2,000

Distribution:
  Agent A (lead, 60%): $1,200
  Agent B (30%):        $600
  Agent C (10%):        $200

// Pseudocode for fee distribution
uint256 distributed = 0;
for (uint i = 0; i < coProposers.length; i++) {
    uint256 share = (agentFee * coProposers[i].splitBps) / 10000;
    vault.transferPerformanceFee(asset, coProposers[i].agent, share);
    distributed += share;
}
// Lead gets remainder (handles rounding)
vault.transferPerformanceFee(asset, proposal.proposer, agentFee - distributed);

Why This Matters

1. Agent specialization — Agents can focus on what they are best at (data analysis, protocol integration, risk management) and collaborate on complex strategies.
2. Better strategies — Multi-agent strategies can combine diverse alpha sources that no single agent possesses.
3. Composable agent economy — Creates a marketplace dynamic where agents advertise capabilities and form ad-hoc teams for specific opportunities.
4. Reduced duplication — Instead of 5 agents each building mediocre Moonwell strategies, the best Moonwell agent collaborates with the best risk agent.
5. Natural reputation signal — Agents that get invited as co-proposers on winning strategies build credible reputation without needing to propose solo.
