Public Allocator

Overview

MetaMorpho is a protocol for funds allocations and risk management on top of Morpho Blue. The Public Allocator is a contract that MetaMorpho vault owners can enable as allocator to let anybody reallocate the vault's funds to fill their liquidity needs.

The Public Allocator's function reallocateTo (source, interface) reallocates some liquidity from multiple markets to one market. It takes as input withdrawals, a list of pairs, which will be the markets and amounts that will be reallocated, and supplyMarketParams, a MarketParams, which is the market in which to supply the reallocated funds. Note that the id of the markets in withdrawals must be sorted, and that supplyMarketParams cannot be a market of withdrawals.

The Public Allocator provides the possibility to the vault owner or a per vault settable admin to constrain the public reallocation:

  • Max flows: Each market has a max inflow (maxIn) and max outflow (maxOut), that can be set by the vault owner or the Public Allocator vault admin. The markets from which funds are withdrawn through reallocateTo increase their maxIn and decrease their maxOut, and the market in which funds are deposited decrease their maxOut and increase their maxIn.
  • Fee: If set, user must pay a fee in ETH to be able to call reallocateTo. The vault owner or the Public Allocator vault admin can set this fee, as well as taking the accumulated fees out by calling transferFee.

Deployments

See the documentation.

Testing

To run tests: forge test. Note that running the tests this way will use this repository's compilation settings for dependencies (Morpho & MetaMorpho), potentially different from the settings used for deployment of those dependencies.
