Cap - stcUSD
not rated yetCap is a stablecoin protocol that provides verifiable yield through a covered credit engine. Users deposit USDC to mint cUSD (pegged 1:1 to USD), then stake cUSD into stcUSD — a yield-bearing ERC-4626 vault token. Yield is generated by an autonomous layer of institutional operators (banks, HFT firms, market makers, RWA protocols) who borrow from Cap's reserves and execute yield-generating strategies. The risk of yield generation is covered by restakers who delegate locked assets (via EigenLayer and Symbiotic) to back operators, with slashing mechanisms protecting stablecoin holders against defaults.
How Cap and stcUSD work:
- Deposit USDC to mint cUSD at a ~1:1 ratio — cUSD is redeemable for a proportional share of the reserves
- Stake cUSD into stcUSD (ERC-4626 vault) to earn auto-compounding yield
- Yield is generated by whitelisted institutional operators who borrow reserve capital and execute proprietary strategies
- Operators must exceed a dynamic hurdle rate (benchmarked against Aave's stablecoin lending rate) to participate
- Restakers delegate locked ETH/assets via EigenLayer and Symbiotic to underwrite operator risk — slashing protects cUSD holders
- The protocol uses a covered credit engine — yield-generation risk is programmatically insured by restaker collateral
Cap was founded by Benjamin Sarquis Peillard in 2024 and raised $11M in seed funding led by Franklin Templeton, with participation from Triton Capital, Susquehanna (SIG), Nomura's Laser Digital, and GSR. The protocol launched on Ethereum mainnet on 18 August 2025, and cUSD is also available on MegaETH and Tempo as a LayerZero OFT asset. Cap launched its CAP governance token in June 2026 (10B fixed supply; governance rights are being phased in).

Strategy
- Mint cUSD by depositing stablecoins
- Deposit USDC into Cap's Vault to mint cUSD at ~1:1 (mint fees are set dynamically by the Minter contract)
- cUSD reserves are currently almost entirely USDC, plus a small position in WisdomTree's tokenized WTGXX money-market fund; further stablecoins and tokenized funds can be whitelisted
- cUSD is always redeemable for underlying reserve assets
- Stake cUSD into stcUSD
- Deposit cUSD into the stcUSD ERC-4626 vault to receive yield-bearing stcUSD tokens
- Yield auto-compounds — the stcUSD/cUSD exchange rate appreciates over time
- Any cUSD holder has open access to stcUSD — no minimum or whitelist required
- Earn yield from institutional operators
- Whitelisted institutional operators borrow reserve capital to execute yield strategies
- Operators must exceed the dynamic hurdle rate (benchmarked against Aave) to participate
- Yield distribution: hurdle rate portion flows to stcUSD holders, fixed premium to restakers, excess to operators
- Idle reserves also earn base yield via Aave and Morpho integrations
- Redeem anytime
- Unstake stcUSD back to cUSD at the current exchange rate (includes all accrued yield)
- Redeem cUSD for underlying stablecoins via the PSM — subject to reserve liquidity
- Multi-collateral redemption distributes proportional basket outputs based on current weights
Yield Source
Yield is generated through Cap's three-sided marketplace of stablecoin holders, institutional operators, and restakers. The covered credit engine ensures that yield-generation risk is programmatically insured — operators borrow reserve capital, execute strategies, and return yield above the hurdle rate to stcUSD holders, with restaker collateral slashed in case of defaults.
Primary yield sources:
- Institutional operator strategies: Banks, HFT firms, market makers, private equity shops, and DeFi protocols borrow reserves to execute proprietary yield-generating strategies — these may include lending, market-making, arbitrage, and RWA investments
- Base reserve yield: Idle capital in the reserve earns passive yield via integrated protocols (Aave, Morpho) — this establishes a yield floor even without operator borrowing
- Fee Auction mechanism: A Dutch auction system converts protocol fees and operator yields into cUSD for distribution to stcUSD holders
Yield mechanics:
- Hurdle rate: A dynamic minimum yield rate that operators must exceed — set as a function of market rate (benchmarked against Aave) and utilization rate
- Example distribution: If an operator generates 15% yield, ~8% (hurdle rate) flows to stcUSD holders, ~2% (fixed premium) goes to restakers, and ~5% is operator profit
- Auto-compounding: Yield accrues to the stcUSD vault automatically — no manual claiming required
- Covered risk: Operator defaults trigger slashing of restaker collateral, which is auctioned and redirected to Cap's reserve to make stcUSD holders whole
The covered credit engine is Cap's key differentiator — unlike protocols where users bear yield-generation risk directly, Cap's restaker slashing mechanism provides programmatic downside protection for stcUSD holders, verifiable on-chain.
Strategy Limits
Deterministic Constraints
- Yield depends on operator participation — if no operators exceed the hurdle rate, only base Aave/Morpho yield is earned
- Redemption depends on reserve liquidity — if reserves are fully utilized by operators, redemption may be delayed
- Only whitelisted reserve assets are accepted as minting collateral — currently USDC and WisdomTree's tokenized WTGXX fund
- Cross-chain cUSD (via MegaETH/LayerZero) introduces bridge and oracle dependencies
Probabilistic Constraints
- Operator strategy performance varies with market conditions — low volatility or adverse conditions may reduce yields
- Restaker slashing coverage depends on sufficient delegation — undercollateralized operators increase systemic risk
- Reserves are concentrated in USDC — a USDC depeg or freeze would directly impair cUSD backing
- Protocol launched in August 2025 — just over a year of track record, with limited exposure to different market cycles

Risk Analysis
not rated yetPotential Risks
Based on the official Cap risk documentation and independent analysis:
- Smart Contract Risk - Despite 8 security reviews and a $1M bug bounty, potential code vulnerabilities in Cap's contracts, EigenLayer integration, or the slashing/redistribution mechanism could lead to loss of funds
- EigenLayer/Symbiotic Platform Risk - Cap inherits all risks from the Shared Security Networks it relies on; SSN-level exploits or governance failures directly impact Cap's security model
- Reserve Asset Depeg Risk - Underlying reserve assets (currently USDC, plus a small WisdomTree WTGXX position) may depeg, freeze, or be forfeited — losses are socialized across all cUSD holders via proportional redemption
- Operator Default Risk - Operators execute proprietary strategies off-chain; strategy failures or operator insolvency could trigger slashing cascades — coverage depends on sufficient restaker delegation
- Restaker Undercollateralization Risk - Underwriter collateral is volatile and concentrated in BTC wrappers and ETH LSTs (October 2026: uniBTC ~48%, LBTC ~17%, wstETH ~13%, weETH ~8%, SolvBTC ~5% per DefiLlama); sharp drawdowns, a wrapper depeg or looping increase liquidation risk and may leave insufficient coverage for stcUSD holders
- Redemption Liquidity Risk - If reserve assets are fully utilized by operators, redemptions may be delayed until operators repay or positions unwind
- Bridge and Oracle Risk - Cross-chain cUSD users are exposed to third-party bridge exploits and oracle pricing failures
- Idle Reserve Integration Risk - Idle assets deposited in Aave and Morpho expose Cap to those platforms' smart contract vulnerabilities
- Governance and Maturity Risk - Protocol is just over one year old with centralized access controls; the CAP token launched in June 2026 but governance rights are still being phased in
Risk Analysis (3rd Parties)
Summary
Cap's stcUSD offers yield-bearing stablecoin exposure through a novel covered credit engine that programmatically insures yield-generation risk. Institutional operators (banks, HFT firms, market makers) borrow reserve capital to execute proprietary strategies, while EigenLayer/Symbiotic restakers provide overcollateralized coverage — with slashing mechanisms protecting stcUSD holders against operator defaults. The protocol has undergone 8 security reviews (Trail of Bits, Zellic, Spearbit, Sherlock, Certora, Octane), maintains a $1M active bug bounty, and is backed by Franklin Templeton, Susquehanna, and Nomura's Laser Digital in an $11M seed round. However, significant risks remain: operator strategies are proprietary and execute off-chain with limited visibility, the protocol inherits all EigenLayer/Symbiotic platform risks, reserves are concentrated in USDC with most of it lent to borrowers, and the covered credit engine has limited real-world battle testing. Users should weigh the innovative downside protection mechanism against the protocol's youth and deep dependency on Shared Security Network infrastructure.
See Cap's audit reports: Cap Protocol Audits
Extensive Audit Coverage: Cap lists 8 security reviews: Zellic (February 2025), Trail of Bits (March 2025), Spearbit (April 2025), Electisec (May 2025), Recon invariant testing (May 2025), Sherlock contest (July 2025), Certora formal verification of the EigenLayer integration (September 2025), and Octane's review of the CAP token (March 2026). A $1M Sherlock bug bounty remains active.
Covered Credit Engine: Cap's core innovation is programmatic downside protection for stablecoin holders. Operators must secure overcollateralized delegations from restakers before borrowing. If an operator defaults or becomes undercollateralized, liquidators trigger a Dutch auction to slash restaker collateral and redirect proceeds to Cap's reserve — making stcUSD holders whole.
Institutional Backing: $11M seed round led by Franklin Templeton with participation from Susquehanna (SIG), Nomura's Laser Digital, GSR, Triton Capital, and RockawayX. Operators are whitelisted regulated financial institutions, reducing (but not eliminating) counterparty risk. The protocol won the TOKEN2049 NEXUS Startup Competition.
EigenLayer Platform Dependency: Cap is built on EigenLayer and Symbiotic as Shared Security Networks. The protocol inherits all platform risks from these SSNs — including potential slashing bugs, governance failures, or systemic issues. EigenLayer itself is still maturing, and the interaction between Cap's slashing logic and EigenLayer's redistribution mechanism introduces composability risk.
Operator Opacity: While operators are whitelisted institutions, their actual yield-generating strategies are proprietary and execute off-chain. Users have no visibility into what specific positions operators take with borrowed capital. Off-chain Guarantor Agreements provide recourse, but their effectiveness depends on counterparty solvency and legal enforceability.
Reserve Concentration and Utilization: cUSD was designed around a multi-asset basket, but on-chain reserves are currently almost entirely USDC (plus a small WisdomTree WTGXX position), so a USDC depeg or freeze would hit all cUSD holders directly. On 1 October 2026 about 70% of the Ethereum vault's USDC was lent to borrowers and about 30% sat in the Aave-based fractional reserve, so redemptions beyond that buffer depend on borrowers repaying.
Young Protocol: Cap launched on Ethereum mainnet in August 2025, giving it just over a year of history. TVL has retraced substantially from its January 2026 peak. Cap reports that it neither gated redemptions nor lost its peg during the October 2025 liquidation cascade or the Stream Finance contagion that followed, but it has not been tested through a full market cycle, and the slashing mechanism has not yet been exercised by a real borrower default.
