Overview

The Centrifuge Protocol is built on an immutable core protocol architecture, with a modular design that enables customized products to be built on top of it.

Immutable core​

The immutable core includes:

  • Hub: Central orchestration layer for pool management, accounting, and share class coordination
  • Spoke: Local registry and integration point for cross-chain deployments

Modular extensions​

Built on top of the immutable core, the protocol supports various extension points that enable customization without modifying core contracts:

  • Adapters: Cross-chain messaging adapters integrating with LayerZero, Wormhole, Axelar, and recovery mechanisms
  • Hooks: Transfer hook implementations (FreezeOnly, RedemptionRestrictions, FullRestrictions, FreelyTransferable)
  • Hub Managers: NAVManager for net asset value tracking and SimplePriceManager for single-share-class pool pricing
  • Spoke Managers: OnOfframpManager for asset custody, MerkleProofManager for permissioned operations, QueueManager for batched syncing
  • Valuations: Asset valuation implementations (IdentityValuation for 1:1 pricing, OracleValuation for oracle-based pricing)
  • Vaults: ERC-4626/ERC-7540 vault implementations (AsyncVault, SyncDepositVault), request managers, and router
