Developer Overview

Current Phase: Shadow Mainnet Testing

Multyr contracts are deployed on Arbitrum One. The system is currently in validation phase. Deposits are not open to the public. Behavior described on this page reflects the protocol's designed behavior; some mechanisms are active in shadow testing, others become active at public launch. See the Status page for details.

Multyr is a non-custodial, multi-chain capital allocation protocol built around a modular ERC-4626 vault architecture.

It enables developers, protocols, and integrators to:

  • deposit and manage capital programmatically
  • build products on top of yield-bearing vault shares
  • access on-chain and indexed data for analytics
  • integrate automated yield strategies without managing execution

Core Primitive​

The main integration point is the CoreVault, an ERC-4626 compliant vault.

  • accepts USDC deposits
  • issues vault shares
  • allocates capital across strategies
  • returns yield via share price appreciation

What You Can Build​

Multyr is designed as an infrastructure layer.

Integrators​

  • deposit and withdraw capital
  • integrate yield into existing products
  • use vault shares as composable assets

Frontends & Dashboards​

  • display TVL, APY, allocations
  • track user positions
  • visualize yield and historical performance

Keepers & Automation​

  • trigger maintenance operations
  • execute rebalancing and harvesting
  • integrate with Chainlink Automation

Analysts & Indexers​

  • consume events
  • query subgraph data
  • reconstruct historical state

Architecture Overview​

Multyr is composed of multiple interacting layers:

  • CoreVault — accounting, deposits, withdrawals
  • BufferManager — liquidity management
  • StrategyRouter — capital allocation
  • Adapters — external protocol integrations
  • Fee System — fee accrual and distribution
  • Oracle Layer — pricing and validation

Multi-Chain Design​

Multyr is designed for multi-chain deployment:

  • currently deployed on Arbitrum One (chainId 42161)
  • expansion planned to Ethereum, Base, and additional L2 networks

When multi-chain deployment becomes active, each chain will operate as an independent system with its own vaults, strategies, liquidity, and governance configuration. Capital is not bridged automatically between chains.

See Multichain Architecture for the full design.

Developer Flow​

Typical integration flow:

  1. discover vault
  2. deposit assets
  3. receive shares
  4. track share value
  5. withdraw or redeem

Next Steps​

  • Core Concepts — understand how the system works internally
  • Integration Guide — interact with the protocol
  • Events & Indexing — consume data
  • Contracts & Modules — technical architecture

Summary​

Multyr provides:

  • a standard ERC-4626 interface
  • modular yield strategies
  • permissionless integration

Designed for:

→ composability → automation → capital efficiency
