Background

Maple is a decentralized corporate credit market. Maple provides capital to institutional borrowers through globally accessible fixed-income yield opportunities.

For Borrowers, Maple offers transparent and efficient financing done entirely on-chain.

  • Funds can leverage their reputation to borrow undercollateralized without constant fear of liquidation and margin calls
  • Borrowers access pools of capital governed by smart contracts and liaise with Pool Delegates to confidentially complete loan assessments

For Liquidity Providers, Maple offers a sustainable yield source through professionally managed lending pools.

  • Diversified exposure across premium borrowers with staked MPL-<liquidityAsset> 50-50 Balancer Pool Tokens (BPTs) providing reserve capital against loan defaults (E.g., MPL-USDC 50-50 BPTs for USDC Pools)
  • Set and forget solution with diligence outsourced to Pool Delegates
  • Interest is accrued and reinvested to enable capital to compound over time

For Pool Delegates, Maple is a vehicle to attract funding and earn performance fees.

  • Maple is a new platform providing decentralised asset management infrastructure
  • Globally accessible pools enable increased AUM from varied liquidity sources to be provided to networks of premium, creditworthy borrowers
