The Multyr Protocol
Multyr is on-chain infrastructure for capital allocation across DeFi. The protocol is currently deployed on Arbitrum One (chain ID 42161), with multichain expansion planned.
The system is composed of ERC-4626 vaults, allocation logic, guardrails, and governance modules. It is built to apply rules on-chain rather than discretionary portfolio management behind an interface.
Current deployment
Architecture and core components
Capital moves through a central vault, liquidity buffers, strategy routers, isolated strategy vaults, and scoped adapters. Governance and fee routing sit alongside the execution stack rather than above it.
CoreVault
The central ERC-4626 vault contract. It accepts deposits, issues shares, and delegates capital allocation to the StrategyRouter.
BufferManager
Maintains hot and warm liquidity buffers. Hot liquidity is immediately withdrawable; warm liquidity is near-liquid and can be unwound quickly.
StrategyRouter
Executes allocation and rebalancing across Strategy Vaults. Supports PRIORITY, WEIGHTED, and NONE allocation modes.
Strategy Vaults
Isolated vaults that provide direct exposure to a single strategy. The current USDC Lending strategy allocates across Aave, Euler, Morpho, Compound, and Venus.
Adapters
Scoped execution modules that connect strategies to specific external protocols. A failure in one adapter does not automatically propagate to others.
Fee Router
Collects protocol fees from vault operations and routes them across Treasury, Operations, and Safety Reserve according to configured distribution.
Governance modules
ROOT_TIMELOCK
48h delay that gates all parameter changes.
SAFE_GOV
3-of-5 multisig that proposes and executes governance actions.
SAFE_VETO
1-of-1 multisig that can cancel pending actions during the timelock window.
SAFE_GUARDIAN
1-of-1 multisig that can emergency-pause pausable contracts.
Allocation logic
The protocol does not chase the highest advertised yield opportunistically. It scores eligible targets under encoded constraints and rebalances only when the move passes on-chain guardrails.
- Current yield across eligible targets
- Available liquidity at size
- Capacity remaining within per-strategy caps
- Stability signal based on rolling yield variance
- Execution cost sensitivity
Rebalancing guardrails
Every rebalance batch is checked on-chain. These controls are part of execution, not advisory risk language.
Cooldown between rebalance batches
Batch size limits on number of actions per batch
Adapter allowlist so only approved targets are used
Oracle freshness and deviation checks
NAV delta limits with revert-on-excess move
Per-strategy and aggregate loss caps
Health checks that skip unhealthy targets during deposits
Multichain roadmap
Arbitrum is the initial deployment because of its L2 cost profile, deep DeFi integration, and mature tooling. Additional chains will be evaluated, but no specific expansion timeline is committed.
- Underlying protocol maturity on the target chain
- Liquidity conditions
- Oracle availability
- Governance capacity to monitor additional deployments
