Three Stablecoin Markets Go Live
Aave has put its first externally curated lending markets into operation on V4, handing three markets on Ethereum to institutional DeFi platform Sentora. The markets let users borrow Ripple’s $RLUSD, PayPal’s $PYUSD and Origin’s $OUSD against selected crypto assets, and Aave’s official announcement confirms Sentora sets each market’s collateral requirements, interest rate curves, price oracles and liquidation parameters. All three draw on a dedicated Sentora Liquidity Hub on Ethereum, effectively a shared liquidity pool that holds the assets available for borrowing and feeds the individual markets, and each market keeps separate borrowing conditions despite drawing from that same Hub, so a curve or liquidation threshold set for one does not bind another. Users reach the three markets through Aave Pro, the interface Aave built for its curated lending products, and the rollout marks the first external curation on V4 in the Aave protocol. The launch lands while the Aave price holds a place in the market’s wider lending conversation, though the announcement itself carries no token-level figures. The market composition is explicit. The $RLUSD Yield market accepts four collateral assets: USDe, PRIME, mWIN and PST. Sentora’s $OUSD Yield market takes the same four but issues $OUSD as the borrowed asset. A third market, Bluechip, supports borrowing $RLUSD, $PYUSD and $OUSD against kBTC, a Bitcoin-backed asset. Sentora’s October 22 research article frames the deployment as the first governance-approved Hub and Spoke deployment operated by an external curator on Ethereum, meaning an independent risk manager now runs dedicated lending markets on Aave’s infrastructure while staying inside safeguards the DAO sets.
Separate Liquidity, Shared Safeguards
Aave V4 separates where lending liquidity sits from where users borrow. Liquidity Hubs hold the funds and keep the accounting for supplied assets, while individual Spokes connect to those Hubs and decide which collateral borrowers may post, how much they can draw and when a position becomes eligible for liquidation. Each Spoke receives its borrowing and supplying limits from the Hub it connects to, and emergency controls can restrict activity when needed. Borrowing positions are accounted for separately inside each Spoke, so collateral and debt in one market never merge with another. Borrowing costs move with utilization: heavier use of an asset’s available liquidity raises rates for borrowers and the returns to suppliers, the mechanism that drives yield farming income on the platform. V4 also applies a risk premium based on collateral quality, so borrowers posting riskier assets can face higher charges. The architecture has already hosted specialized products. In September, Aave opened an equities market on Base that accepts seven Coinbase tokenized stocks as collateral for USDC loans with an initial borrowing cap of $21 million, consistent with the founder’s public expectation that tokenized stock lending will overtake crypto lending next year. Aave Labs reported V4 deposits surpassed $1 billion during September, alongside $310 million in active loans. On safeguards, Aave governance keeps ownership of the underlying contracts: any change that raises market risk passes through a 48-hour timelock, and new collateral assets require a governance review before listing. Sentora says its platform has allocated more than $2 billion across onchain strategies and runs more than 1,000 risk models in each, while its Risk Radar covers more than 40 DeFi protocols across 12 or more blockchain networks, now including Aave V4. A fourth market, $PYUSD Yield, appears in Sentora’s published architecture diagram as planned, though its collateral assets remain unconfirmed. Separately, an October 14 proposal from Babylon Labs would let users borrow stablecoins against native Bitcoin held in vaults on the Bitcoin blockchain; it still awaits governance approval, finalized risk settings and security checks.
