+Abstract
+
+Margarita Finance proposes to deploy CC20 — a Canton Coin-denominated agentic yieldcoin 
+targeting ~20% APY — on the Canton Network. CC20 tokenizes an institutional-grade revolving 
+covered call strategy on CC/USDC into a permissionless, DEX-tradeable yield token. The 
+strategy is executed via multi-counterparty RFQ with Tier 1 institutional market makers, 
+managed by an regulated portfolio manager, and settled via a bankruptcy-remote Luxembourg 
+SPV. Margarita Finance has deployed this infrastructure for NEAR20 (NEAR 
+Protocol) with foundation-backed liquidity and SOL20 with Solana backed liqudity coming next. CC20 brings the same battle-tested 
+yield infrastructure natively to Canton, creating a flagship DeFi yield primitive for the 
+Canton Coin economy.
+

+
+Specification
+
+1. Objective
+
+Canton currently lacks a native, on-chain yield product for CC holders. CC holders have no 
+passive yield mechanism denominated in their native token. This proposal delivers CC20: a 
+Canton-native yieldcoin that generates yield by running a systematic and propriatory covered call strategy 
+on CC with institutional market makers, wrapping the accrued option premium into a 
+continuously appreciating token. The target APY is ~20% based on backtesting and market 
+maker quotes; this is a target, not a guarantee. CC20 gives the Canton ecosystem its first 
+institutional-grade yield primitive — composable, permissionless at the DEX layer, and 
+compliant at the issuance layer.
+
+2. Implementation Mechanics
+
+Strategy: Daily rebalancing into weekly ATM covered calls on CC. Each day, 1/5th 
+tranche of the NAV is deployed into a fresh 1-week option position. Competitive quotes are 
+collected from multiple Tier 1 institutional market makers (including STS Digital, GSR, and 
+others) via multi-counterparty RFQ. The best execution is selected by the regulated 
+portfolio manager. Collected option premium accrues daily 
+into the CC20 token's NAV.
+
+Tokenization: CC20 is issued by a Luxembourg bankruptcy-remote SPV as independent Portfolio Manager and 
+Calculation Agent. Margarita Finance acts as product sponsor — providing strategy parameters, 
+smart contract infrastructure, and agentic operational tooling. Assets are held in Fireblocks 
+institutional custody. Trade execution and counterparty selection are fully independent of 
+Margarita Finance.
+
+On-chain Settlement: CC20 smart contracts are deployed on Canton. Token mints and burns 
+are publicly verifiable on-chain. NAV is calculated daily by Verified Assets Limited and 
+published as a price feed. Investors hold CC20 tokens whose price reflects the growing 
+strategy NAV; yield accrues continuously into the token price with no fixed maturity.
+
+DEX Access: CC20 tokens are distributed to qualified investors via the permissioned 
+issuance layer (KYC at SPV level) and made available permissionlessly on Canton-compatible 
+DEX infrastructure for secondary trading. This dual-layer structure — permissioned issuance, 
+permissionless secondary — replicates the architecture proven with SOL20 on Raydium and 
+NEAR20 on RHEA Finance.
+
+Agentic Operations: Operational workflows (RFQ issuance, on-chain product minting, NAV 
+reporting) are automated via an agent-powered backend. AI is not used in investment 
+decision-making or portfolio management, which remains the exclusive domain of Verified 
+Assets Limited.
+
+ 3. Architectural Alignment
+
+CC20 aligns directly with Canton's architecture and ecosystem priorities:
+
+- Privacy-preserving settlement: Canton's native privacy model is well-suited to 
+  institutional OTC derivative workflows, where trade-level confidentiality is a requirement 
+  for Tier 1 market maker participation. CC20's settlement layer benefits from and 
+  demonstrates Canton's privacy primitives in a live financial product.
+- Financial-grade composability: Canton is designed for institutional financial 
+  workflows. CC20 is a production financial instrument — not a prototype — bringing 
+  real institutional capital flows and regulated infrastructure onto Canton rails.
+- DeFi liquidity: CC20 creates the first sustainable, non-inflationary yield source 
+  denominated in CC. This is foundational for DeFi composability: yield-bearing CC20 can 
+  serve as collateral, be integrated into lending protocols, and attract external liquidity 
+  to the Canton ecosystem.
+- CIP alignment: CIP-0082 explicitly targets "DeFi app(s), liquidity seeding, and 
+  critical infrastructure." CC20 fulfills all three: it is a live DeFi application, seeds 
+  CC liquidity via institutional market maker participation, and provides reusable 
+  tokenization infrastructure for future Canton-native yield products.
+
+ 4. Backward Compatibility
+
+No backward compatibility impact. CC20 is a net-new smart contract deployment and DEX 
+liquidity pool. No existing Canton contracts, integrations, or workflows are modified.

+
+ Motivation
+
+Canton Coin currently has no native yield product. CC holders who wish to earn yield on 
+their position must bridge assets off-chain or accept custodial risk in CEX staking 
+programs. This is a structural gap: without a native yield primitive, CC has limited DeFi 
+composability and reduced attractiveness as a reserve or treasury asset for protocols and 
+institutions building on Canton.
+
+CC20 fills this gap with a production-grade solution backed by a track record: Margarita 
+Finance's x20 yieldcoin infrastructure is live on Solana (SOL20) and NEAR Protocol 
+(NEAR20), with foundation-backed liquidity and institutional market maker 
+participation. The underlying strategy — revolving covered calls executed via multi-dealer 
+RFQ — has been backtested across market cycles and is managed by Verified Assets Limited, 
+an FCA-regulated portfolio manager.
+
+For the Canton ecosystem, CC20 delivers: a non-inflationary CC yield source for holders 
+and protocols; a flagship DeFi application demonstrating Canton's suitability for 
+institutional financial products; and reusable tokenization infrastructure that can 
+support future Canton-native yield instruments across additional asset classes.
+
+---
+
+ Rationale
+
+The covered call yieldcoin structure is the preferred approach for three reasons:
+
+Proven infrastructure. SOL20 and NEAR20 are live, not prototypes. The smart contracts, 
+SPV structure, regulated portfolio manager relationship, and market maker network are 
+operational. Deploying CC20 is an extension of proven infrastructure to a new chain, not 
+a greenfield build.
+
+Institutional-grade compliance. The Luxembourg SPV / regulated PM structure 
+provides a compliance layer that pure DeFi yield approaches cannot. This is important for 
+Canton, which explicitly targets institutional adoption. CC20 is the yield product 
+institutions can hold without regulatory ambiguity.
+
+Sustainable yield mechanics. Unlike liquidity mining or inflationary reward schemes, 
+covered call premium is a real economic return derived from market maker demand for 
+options exposure. The yield does not dilute CC supply and is not dependent on protocol 
+token emissions. This makes CC20 a durable, market-driven yield source rather than a 
+temporary incentive program.
+
+Alternative approaches considered: (1) staking rewards — rejected as inflationary and 
+not Canton-native; (2) lending protocol yield — rejected as dependent on borrower demand 
+and not yet available on Canton at scale; (3) cross-chain yield bridging — rejected as 
+introducing unnecessary bridge risk. The covered call yieldcoin approach delivers 
+sustainable, compliant, Canton-native yield with the lowest implementation risk given 
+existing infrastructure.
