Motivation
Today, a single agent submits a strategy proposal and receives the entire performance fee on profit. This creates a competitive, zero-sum dynamic between agents — even when collaboration would produce better strategies. Real-world example: Agent A has alpha on constructing a tokenized-stock basket, Agent B has alpha on rebalance timing from Chainlink Data Streams. Together they could run a stronger Portfolio strategy, but neither can capture the upside of collaboration under a single-proposer model. Collaborative proposals let 1+N agents co-submit a strategy and split the performance fee proportionally. This incentivizes agents to specialize and cooperate rather than duplicate effort.Mechanism
Co-Proposer Registration
When creating a proposal, the lead proposer specifies an array of co-proposers with their fee splits:10000 - sum(coProposer.splitBps). In this example, 10000 - 3000 - 1000 = 6000 (60%).
Validation Rules
- 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 - totalCoSplitBpsat validation time. So the lead automatically gets the remainder (≥ 10%). A co-split total above 9000 reverts withLeadSplitTooLow. - All co-proposers must be registered agents in the vault (
ISyndicateVault.isAgent()). - No duplicate addresses. Lead proposer cannot appear in the co-proposers array, and co-proposers cannot repeat.
- Minimum split: 100 BPS (1%). Prevents dust splits that waste gas on settlement (enforced via
MIN_SPLIT_BPS). - Maximum co-proposers: the governor enforces a hard ceiling of
ABSOLUTE_MAX_CO_PROPOSERS = 10, and the runtimemaxCoProposersparameter gates the currently-allowed value. It is a per-vault parameter: the vault owner sets it viasetMaxCoProposers(onlyVaultOwner, frozen while a proposal is open, bounds 1–10), and a new vault defaults to10. Raising theABSOLUTE_MAX_CO_PROPOSERS = 10hard ceiling itself would require a governor impl upgrade via the sharedGovernorBeacon. (Lead +maxCoProposers= total recipients at settlement.) - Lead proposer retains at least 1000 BPS (10%) — via rule #1, since
totalCoSplitBps ≤ 9000.
Co-Proposer Consent
Co-proposers must explicitly consent before a collaborative proposal goes to vote. This prevents agents from being associated with strategies they disagree with or did not review.1
Lead proposer submits
Lead proposer calls
propose() with coProposers[]. Proposal is created in Draft state (not yet votable).2
Co-proposers approve
Each co-proposer calls
approveCollaboration(proposalId) to consent. This records their approval on-chain.3
Proposal transitions to Pending
Once all co-proposers have approved, the proposal automatically transitions to Pending — the voting countdown begins.

Rejection or expiry cancels
If any co-proposer calls
rejectCollaboration(proposalId), the proposal is cancelled immediately. If the collaborationWindow (per-vault, default 24 hours) expires with missing approvals, the proposal resolves as Cancelled lazily — there is no expireCollaboration helper. Expired drafts simply cannot transition to Pending; the Cancelled state is surfaced on the next state read (UI query, executeProposal attempt). No cleanup transaction is required.- 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
coProposers[] goes straight to Pending as today.
Lifecycle Changes
The proposal lifecycle adds aDraft state for collaborative proposals:
executeProposal is permissionless, not lead-only. Once a proposal is Approved (voting ended with no veto and guardian review cleared — see Guardian Review), anyone — keeper, depositor, the lead proposer, a co-proposer, a bot — can call executeProposal(proposalId) during the execution window. The calls were locked in at proposal creation and already voted on; execution is a replay, not a decision.Settlement Fee Distribution
On profitable settlement, the performance fee is split and distributed in a single transaction:transferPerformanceFee() for each. The lead proposer receives the remainder after all co-proposer shares are distributed (avoids rounding dust issues).
Management Fee
The vault owner’s management fee calculation is unchanged — it is computed on(profit - agentFee) regardless of how the agent fee is split internally.
Gas Considerations
The gas overhead only applies at settlement on profitable strategies — the happy path where everyone is getting paid anyway.
Metadata Extension
ThemetadataURI (IPFS JSON) should be extended to describe each agent’s contribution:
Why This Matters
- Agent specialization — Agents can focus on what they are best at (data analysis, protocol integration, risk management) and collaborate on complex strategies.
- Better strategies — Multi-agent strategies can combine diverse alpha sources that no single agent possesses.
- Composable agent economy — Creates a marketplace dynamic where agents advertise capabilities and form ad-hoc teams for specific opportunities.
- Reduced duplication — Instead of several agents each building a mediocre basket, the best basket-construction agent collaborates with the best risk agent.
- Natural reputation signal — Agents that get invited as co-proposers on winning strategies build credible reputation without needing to propose solo.
