In a significant move for decentralized finance (DeFi), RedStone has introduced its price feed infrastructure on the Stellar network. This deployment offers an essential data layer, enhancing decentralized applications that traditionally focus on payment solutions.
The newly launched price feeds now include pricing information for key cryptocurrencies and stablecoins on Stellar’s mainnet, such as Bitcoin (BTC), Ethereum (ETH), USD Coin (USDC), and PayPal USD (PYUSD). Additionally, data for the Franklin Templeton BENJI tokenized money market fund is also part of this update.
RedStone has emphasized that these price feeds are crafted to bolster various financial applications, including lending markets, decentralized exchanges (DEXs), and platforms dealing with tokenized real-world assets. This development marks a pivotal expansion in Stellar’s DeFi ecosystem as developers continue to innovate in areas like lending and asset tokenization.
According to RedStone, the price feeds utilize a deviation-based update mechanism, along with freshness checks, ensuring the reliability and accuracy of the pricing data for crucial financial applications.
Co-founder Marcin Kazmierczak noted that Stellar has consistently showcased its potential as a robust blockchain for real-world financial transactions, particularly in payments and stablecoins. He remarked that the introduction of a high-level oracle infrastructure was necessary for the network to advance in developing sophisticated financial applications.
As RedStone enters the competitive oracle landscape, it aims to challenge predominant players like Chainlink, which holds approximately 64% of the market share, according to DeFiLlama data. Other notable competitors include Chronicle, Pyth, and internal protocol oracles.
The urgency of this launch follows a recent exploit in the DeFi space that exposed vulnerabilities linked to price feeds and collateral assessment within lending protocols. In February, a security breach drained around $10 million from a lending pool managed by YieldBlox DAO. This exploit was facilitated by a price manipulation of the USTRY token, which was being used as collateral.
A security report from blockchain firm BlockSec indicated that the lending protocol relied on price data from an illiquid market, which was vulnerable to manipulation. This allowed the attacker to exploit inflated collateral values and borrow assets beyond their actual worth. A representative from RedStone explained that pricing determined by thin on-chain markets significantly heightens the risk of such manipulations.
To mitigate these risks, RedStone’s price feeds employ deviation-based updates, typically ranging from 0.5% to 1% for stablecoins, along with daily refreshes to maintain current and accurate data.
Overall, RedStone’s move to provide robust price feeds on Stellar not only addresses pressing security issues but also strengthens the foundation for future financial innovations within the DeFi sector.
