Diagram: User Interaction Flow (Description)

Here's a visual breakdown for rendering the flow diagram:

[User Wallet]

    |

    |--- (1) Deposit Stablecoin (USDC) --->

    |

[DeraEngine Contract]

    |

    |--- Validate Token Address & User Approval

    |--- Split Amount by Allocation %

    |

    |--- For Each Pool:

          |

          |--- Deposit into pool or vault

    |

    |--- (2) Mint DERA Token to User ---> [DERA1 Contract]

    |

    |--- (3) Passive Yield Accrual Over Time

    |

    |--- (4) User Calls Burn to Redeem

    |

    |--- Withdraw Funds from Connectors

    |

    |--- Send USDC to User Wallet

Interest allocation: What the connector contracts do​

Interest is generated and stored in the form of LP tokens in connector contracts (e.g., Aave pools). Each connector tracks:

  • LP token balance

  • Pool value

Withdrawn interest is routed through the withdrawPerformanceFee function and distributed to the fee recipient.

"Fund/allocation management" Parameters Dera can adjust/Admin function​

The protocol admin, via DeraAdmin, controls fund routing through a limited set of callable functions.

Adding/removing pools​

  • addProtocolPool: Adds a new pool with zero allocation.

  • removePool: Withdraws capital and removes the pool from storage.

Setting allocations ​

  • setProtocolPoolAllocation: Assigns percentage values across pools.

Re-allocating ​

  • Re-allocation is achieved by updating percentages and withdrawing/redepositing funds.

Granting and revoking of roles ​

  • Admin can assign delegate permissions or revoke them via standard access control patterns.

All operations are logged via events and access control is restricted to specific roles with custom access modifiers.

Pool allocations:​

    Dera uses an allocation-based architecture to diversify investment risk across multiple DeFi protocols. Allocation percentages are configurable by the protocol admin and are stored per pool using the ProtocolPool struct.

Pool 1: Protocol description, contract addresses, percentage​

Connector Logic:

  • Deposits USDC in Aave aUSDC Pool

  • Tracks netUnderlyingAssetDeposits and currentYield for fee accounting.

Yield: Accrued directly via Aave pool token rebasing.

Pool 2: Protocol description, contract addresses, percentage​

Connector Logic:

  • Deposit stablecoins.

  • Tracks netUnderlyingAssetDeposits and currentYield for fee accounting. Share price is determined by Fluid and can be checked with  getPricePerShare

Yield: Accrued via the increase in LP token value

This multi-pool strategy minimizes dependence on one DeFi source and improves yield stability.
