TL;DR:
- DIA partnered with River to provide oracle price feeds for satUSD across five blockchains and fundamental valuation for satUSD+.
- The satUSD market feeds include Ethereum, $BNB Chain, BOB, Arbitrum and Base, aligned with River’s omnichain architecture.
- For satUSD+, the Contract Exchange Rate methodology is applied, where the exchange rate is read directly from the vault contract.
SLIDE worked with River to implement Oracle infrastructure on top of the protocol’s omnichain stablecoin system. The integration includes two assets with different valuation logics: satUSDthe overcollateralized stablecoin backed by BTC, ETH, $BNB and liquid staking tokens; And satUSD+the yield token users receive when staking satUSD.
The difference between both assets lies in the fact that satUSD operates in secondary markets across multiple chainsmaking the market price aggregation methodology appropriate. satUSD+ presents another challenge: its value is not determined by the last transaction recorded on a DEX, but by the exchange rate that guarantees the vault contract. Applying market prices to a yield token with scarce liquidity exposes lending protocols and vault strategies outdated or manipulable dataexactly when risk models need them most.
SLIDE: Two methods, one Oracle Stack
For satUSD, market price feeds are deployed on Ethereum, $BNB Chain, BOB, Arbitrum and Basicin line with River’s omni-CDP architecture, where users deposit collateral on one chain and USD on another via Low Zero. Every feed continues to work DIA’s decentralized feeder network: independent feeders extract real-time trading data, aggregate it through a verifiable two-step process on DIA’s proprietary blockchain and publish the result on-chain, without middlemen or opaque pipelines. Any protocol can trace any price back to the source transactions.
For satUSD+ the Contract exchange rate methodology is applied. Instead of observing secondary markets, the feed reads the satUSD+/satUSD rate directly from the vault contract $BNB Chain and calculates the fair value based on what the protocol itself guarantees upon repayment.
The River The team emphasized that for an omnichain system like theirs, there are verifiable prices derived from onchain data is non-negotiableespecially for credit markets and vault strategies that integrate satUSD+.
The integration illustrates a crucial principle for the institutional DeFi sector: assets whose value is determined by contracts, reserves or portfolios require fundamental valuation methods, and not just market observation. The combination of both feeds within the stack of one protocol shows how these approaches function as complements, rather than alternatives.
