What is Scroll?
Scroll is a Layer 2 scaling solution for Ethereum, designed to enhance the performance of the Ethereum network by utilizing zk-rollups. This technology allows for batching transactions off-chain and later verifying them on-chain, reducing gas fees and increasing transaction throughput. Scroll’s zkEVM (Zero-Knowledge Ethereum Virtual Machine) is fully compatible with Ethereum, enabling developers to deploy existing decentralized applications (dApps) with minimal adjustments. Scroll focuses on scalability without compromising security or decentralization.
How RedStone Supports Scroll with Push and Pull Models
RedStone uses two data delivery models: the Push Model and the Pull Model ensuring that dApps can access timely and accurate price feeds for executing smart contracts efficiently.
RedStone’s Push Model
The Push Model delivers data to the blockchain at scheduled intervals, independent of market events. By ensuring price updates occur at a fixed time, this model helps Scroll-based dApps maintain up-to-date price feeds without manual intervention. It is also compatible with other oracle providers, making it easy for developers to integrate RedStone’s data into existing systems on Scroll without significant modifications.
RedStone’s Pull Model
The Pull Model, or on-demand model, provides data only when requested by a dApp, reducing gas fees and latency. This model stores data off-chain in RedStone’s data delivery layer, pulling it onto the blockchain only when necessary. This is ideal for applications that require real-time data without constantly updating the blockchain, ensuring accurate price feeds while minimizing the cost and load on the network.
RedStone’s Supported Price Feeds on Scroll
RedStone provides a range of price feeds for key assets on Scroll, catering to different types of decentralized finance (DeFi) use cases. The supported price feeds include:
WTBC
USDC
USDT
wstETH
pufETH
weETH
STONE
SolvBTC.b
These price feeds cover a wide array of assets, including price feeds for major cryptocurrencies like ETH and BTC, yield-bearing Bitcoin feeds for a new wave of liquid bitcoin, and feeds of liquid staking tokens. RedStone aggregates data from multiple sources, ensuring security and reliability by preventing manipulation and central points of failure.
By providing price feeds for a variety of assets RedStone unlocks the next generation of dApps to be built.
