RedStone powers onchain NAV data for savUSD on Stellar, unlocking DeFi collateral for a $3B RWA market
Stellar’s tokenized real-world asset market has ballooned from roughly $800 million in January to over $3 billion by July 2026. The problem? Most of those assets have been sitting on the sidelines of DeFi, unable to participate as collateral or in lending protocols because reliable onchain pricing simply didn’t exist for them.
RedStone, one of crypto’s more established oracle providers, just plugged that gap for Avant Protocol’s savUSD token. The integration delivers a contract rate feed capturing the savUSD/avUSD exchange rate directly on Stellar, giving DeFi protocols the standardized pricing data they need to actually use these assets.
What RedStone built and why it matters
The feed launched on May 29 and follows Stellar’s SEP-40 oracle standard, a specification designed to let any protocol on the network consume pricing data without building bespoke integrations. Instead of every DeFi app on Stellar needing to wire up its own pricing source for savUSD, they can all pull from the same RedStone feed.
For savUSD specifically, the data functions as onchain Net Asset Value, or NAV, made available continuously for smart contracts running on Stellar’s Soroban execution environment.
The broader SEP-40 implementation kicked off in March 2026, with RedStone planning a gradual rollout throughout the year. Six additional issuers are expected to receive similar oracle support by August, which would meaningfully expand the range of assets available for DeFi composability on Stellar.
RedStone reports no mispricing events across its existing feeds, a claim that carries real weight given how many DeFi exploits trace back to faulty or manipulated price data.
Inside savUSD: the asset getting priced
SavUSD is a senior-tranche token from Avant Protocol, backed 1:1 by USDC and USDT collateral. It derives returns through delta-neutral trading strategies, capturing funding rate payments and basis trade spreads while hedging out directional market exposure.
Pennyworks, an independent third party, conducts weekly NAV calculations to verify the token’s value. Combined with the real-time onchain visibility that RedStone now provides, investors get two layers of price verification: one from traditional auditing cadence, another from continuous oracle feeds.
Before this integration, savUSD existed in a kind of DeFi limbo on Stellar. Without a price feed, a lending protocol can’t accept savUSD as collateral, a DEX can’t properly route trades, and an automated portfolio manager can’t rebalance positions that include it.
Stellar’s RWA growth meets its DeFi bottleneck
Growing from $800 million to over $3 billion in tokenized assets within roughly six months puts Stellar among the fastest-expanding RWA networks in crypto. Each new asset on Stellar previously needed custom pricing solutions, creating a patchwork of data sources that raised integration costs and security risks. Standardizing through SEP-40 means protocols can support new assets faster, with less engineering overhead and fewer potential failure points.
The yield-bearing nature of savUSD makes proper pricing especially critical. Unlike a simple stablecoin pegged to $1, savUSD’s value fluctuates based on accumulated yield. A stale or inaccurate price feed could lead to under-collateralized positions or liquidation failures.
With six more issuers expected to receive RedStone oracle support by August, Stellar’s DeFi layer is approaching something closer to infrastructure maturity.

VIPTradFi Focus: Where Does the RWA Market Stand Today?
1. Crypto outperformed traditional equity indexes following the rate hike, but elevated interest rates remain a key constraint on cross-asset allocation. From September 12 to 18, BTC, ETH, and SOL gained 4.83%, 3.84%, and 9.96%, respectively, while the S&P 500 edged down 0.08%. The U.S. Dollar Index rose 1.11%, and the 10-year U.S. Treasury yield closed at approximately 4.998%. Improving risk appetite is therefore coexisting with elevated discount rates, raising the bar for RWA allocation: investors need to compare not only returns on the underlying assets, but also on-chain liquidity and collateral efficiency. 2. Growth in tokenized equities is occurring even as the overall RWA market remains under pressure. As of September 18, Distributed Asset Value across RWAs stood at $38.503 billion, down 1.13% week over week, while tokenized equities reached $3.056 billion, up 6.03%. This week's data are better explained by capital reallocating across different RWA segments than by a broad-based expansion of the entire RWA market. 3. For exchanges, the opportunity lies in connecting spot holdings, collateral, and derivatives. Reality's distributed asset value stands at approximately $155 million, while eligible rTokens can already be used within Bitget's UTA margin framework. Across CoinGlass's verifiable sample of 177 TradFi instruments, open interest reached approximately $11.498 billion, up 2.06% week over week, even as weekly trading volume declined 7.60%. The medium-term opportunity remains intact, but deeper utilization will depend on liquidity, collateral use, and sustained trading activity. 4.Assets to watch: BTC, ETH, SOL, NEAR, ZEC, gold, tokenized U.S. equities, COST. 5.Key metrics to watch: rToken collateral utilization, the durability of TradFi open interest and trading volume, and next week's employment and consumer data.
