Maple Protocol Overview V1.0.0
The Maple protocol offers the most capital efficient option for institutional borrowing and fixed income lending in decentralized finance.

Lenders can access reliable yield opportunities on Maple by depositing capital into lending pools. These lending pools are managed by experienced professionals, known as Pool Delegates.
See our technical documentation here.
Institutional Borrowers can access transparent and efficient financing on-chain with Maple, leveraging their reputations to borrow under-collateralized without fear of liquidation and margin calls.
Pool Delegates conduct due diligence and agree on terms with Borrowers before funding loans from their designated Liquidity Pool.
Lenders earn a sustainable yield through diversified exposure to crypto's premium institutions and enjoy a set-and-forget solution as diligence is conducted by Pool Delegates.

Lenders - provide capital to a pool to earn interest from Institutional Borrowers as well as any associated MPL lending rewards.
Pool Delegates - credible experts who launch and manage Lending Pools. They each develop their own investment strategy and underwriting process for determining creditworthy borrowers.
Borrowers - institutions looking for capital to fund operations and grow their business. Borrowers currently include hedge frequency traders, prop traders, market makers, exchanges and centralized lenders with a strong requirement for delta neutral strategies.
Pool Cover providers - participants provide Pool Cover by staking MPL tokens into a Balancer Pools as first loss capital. These tokens will be first to be liquidated in the event a Borrower defaults. Cover providers receive a percentage of the interest earned by the pool from borrowers and MPL staking rewards.

    Delegate deploys and initiates lending pool
  4. 4.
    Delegate activates pool by posting pool cover as MPL:USDC Balancer Pool Tokens (BPT)
  5. 5.
    Lenders view delegate profile and add additional BPTs for pool cover to chosen pools
  6. 6.
    Lenders (LPs) review delegate profile and add liquidity to desirable pools
  7. 7.
    Borrower creates borrower profile and details loan terms
  8. 8.
    Delegate views borrower requests and conducts private diligence on terms directly with borrower
  9. 9.
    Once terms are agreed, borrower launches loan contract
  10. 10.
    Delegate funds the loan contract with the pool liquidity
  11. 11.
    Borrower draws down the loan and stakes collateral in one transaction. An Establishment Fee is taken from drawdown and sent to the delegate and Maple DAO Treasury
  12. 12.
    Borrower pays interest according to the scheduled repayment cycle and pays principal with final repayment upon maturity
  13. 13.
    Delegate claims interest on behalf of the pool throughout the loan term and claims principal with final repayment upon maturity
  14. 14.
    Delegates, Lenders, and Cover Providers can all claim available interest throughout the process

Parameters associated with the Maple protocol include those that are pool specific (Pool Parameters), and those that affect the entire system (Global Parameters).

These parameters are determined by the Pool Delegate when first configuring and deploying the pool contract.

These parameters define aspects that cannot be changed post pool deployment.
Liquidity Asset - denominated ERC20 token asset used for a pool to lend to borrowers and accept as interest.
Delegate Fee - percentage of interest generated by the pool that is allocated to delegate.
Staker Fee - this is the percentage of interest generated by the pool that is given to Stakers.

These parameters can be changed post pool deployment.
Pool Capacity - total liquidity value a pool will accept. Once this value is reached, the pool has no more capacity for additional liquidity.
Liquidity Access - delegates determine whether the opportunity to provide liquidity in a pool is open privately to a select list of Ethereum addresses or open publicly to any address.
Cover Access - delegates determine whether the opportunity to provide cover for a pool is open privately to a select list of Ethereum addresses or open publicly to any address.
Lockup Period - this period determines the length of time liquidity in a pool must be locked prior to withdrawal by LPs or Stakers. The period can be decreased by the pool delegate, but not increased.

The global parameters span a broad range of factors that contribute to the possibilities enabled by the Maple protocol. These parameters were first specified by the Maple core team and eventually will be determined via broader Maple governance.
Treasury Fee - fee sent to the Maple DAO Treasury from every loan drawn down from the protocol.
Delegate Fee - fee sent to the delegate from every loan drawn down in their specific pool.
Cooldown Period - the cooldown period is a period of time require to past after an LP or Staker initiates withdraw.
