Loan Dicer Smart Contract

A CosmWasm smart contract (with Provenance extensions) that manages loan dicer token (LDT) contributions and redemptions. The contract keeps track of pending contributions/redemptions, validates scope ownership, and mints/burns tokens via Provenance markers.

✨ Highlights

• Contributions: OTC initiates and finalizes contributions to mint LDT.
• Redemptions: Token holders initiate redemptions to receive underlying scopes, with pooling support.
• Marker integration: Uses Provenance markers for LDT and redemption pooling.
• Reference lookup: Optional human-friendly references for contributions and redemptions.

Contract State (high-level)

• CONFIGURATION: OTC, trust address, LDT denom, redemption marker admin
• PENDING_CONTRIBUTIONS: pending contributions by ID
• PENDING_REDEMPTIONS: pending redemptions by ID
• CONTRIBUTION_REFERENCES: optional reference → contribution ID
• REDEMPTION_REFERENCES: optional reference → redemption ID

Instantiate

Message: InstantiateContractMsg

{
  "otc_address": "...",
  "trust_address": "...",
  "ldt_denom": "...",
  "redemption_marker_admin": "..."
}

On instantiation, the contract stores configuration and creates the LDT marker with the contract as admin.
