DualInvestmentManager

Main entry for creating Dual Investment positions. Validates inputs, coordinates collateral/borrow flows, mints ERC‑1155 positions, and updates risk tracking.

Key Responsibilities

• Validate position params (supported markets, size bounds, direction, time window).

• Compute position value in USD using pToken exchange rate + oracle.

• Route via VaultExecutor for collateral path; via CompoundBorrowRouter for borrow path.

• Mint ERC‑1155 position tokens (ERC1155DualPosition).

Primary Functions

• enterPosition(cTokenIn, cTokenOut, amount, direction, strike, expiry, useCollateral)

  • Validates inputs; generates tokenId; chooses path:

  • Collateral: vaultExecutor.redeemAndSupplyToProtocol(msg.sender, cTokenIn, amount); mint position.

  • Borrow: compute underlyingAmount = amount * exchangeRate / 1e18; borrowRouter.borrowAndRoute(... -> vaultExecutor); vaultExecutor.mintCTokensTo(...); mint position.

• enterPositionWithBorrowed(cToken, cTokenOut, underlyingAmount, direction, strike, expiry)

  • User borrows externally; vault pulls underlying and mints cTokens; position minted from actual minted amount.

• canEnterPosition(user, cTokenIn, amount, useCollateral) -> (bool, reason)

  • Pre‑checks size, balances (collateral) or liquidity (borrow).

• getPositionInfo(tokenId) -> (Position, canSettle, isSettled)

• Admin: setSupportedCToken(cToken, supported), setRiskParameters(maxPos, minPos, maxExpiry, minExpiry).

Events

• PositionEntered(tokenId, user, cTokenIn, cTokenOut, amount, strike, expiry, direction, useCollateral)

Notes

• Position tokenId is user‑scoped (generateTokenIdForUser) to avoid collisions.

• Uses exchangeRateStored() for deterministic conversions during entry.
