Curvefi-Arbitrum is a protocol that operates on the Arbitrum Layer 2 network. It aims to provide efficient and low-cost trading for stablecoins, allowing users to swap various stablecoin assets. Curvefi-Arbitrum was created by the Curve Finance team, with the founding company being Curve Labs. The protocol was launched in 2021 and is named after the concept of "curved" or optimized trading for stablecoins.
Curvefi-Arbitrum offers several benefits when compared to its direct competitors. One of the key advantages is its scalability. Curvefi-Arbitrum is built on the Arbitrum Layer 2 solution, which allows for fast and low-cost transactions. This means that users can perform transactions on the Curvefi-Arbitrum platform without having to worry about high gas fees or network congestion, which are common issues on other blockchain networks.
Another benefit of Curvefi-Arbitrum is its interoperability. The platform allows for seamless integration with other DeFi protocols and applications. This means that users can easily move their assets between different platforms without any friction. This interoperability opens up a wide range of possibilities for users, such as accessing a broader pool of liquidity or utilizing different yield farming strategies.
In terms of security, Curvefi-Arbitrum utilizes the Ethereum mainnet for its security guarantees. This means that users can have confidence in the security and reliability of the platform, as it benefits from the robustness of the Ethereum network.
Furthermore, Curvefi-Arbitrum provides a smooth user experience. The platform is designed to be user-friendly and intuitive, making it accessible to both experienced and novice users. The user interface is well-designed, providing users with easy access to the platform's features and functionalities.
Overall, Curvefi-Arbitrum offers scalability, interoperability, security, and a user-friendly experience, positioning it as a strong contender among its direct competitors in the decentralized finance space.
Curvefi-Arbitrum is a decentralized protocol that operates on the Ethereum blockchain. It leverages the power of blockchain technology to enable users to exchange stablecoins with low fees and minimal slippage. The protocol achieves this through its innovative AMM (Automated Market Maker) design.
Curvefi-Arbitrum is built on top of the Arbitrum network, which is a layer 2 scaling solution for Ethereum. Layer 2 solutions are designed to improve scalability and reduce congestion on the Ethereum mainnet. By utilizing Arbitrum, Curvefi-Arbitrum can offer faster transaction processing times and lower fees compared to operating directly on the Ethereum network.
In terms of functioning, Curvefi-Arbitrum utilizes a liquidity pool model to facilitate stablecoin swaps. Users can pool their stablecoins into smart contracts, which act as liquidity providers. These liquidity pools improve liquidity and allow for seamless token swaps at minimal slippage.
When a user wants to exchange one stablecoin for another, they deposit their tokens into the liquidity pool and receive corresponding tokens in return. The exchange rate is determined by the supply and demand dynamics of the pool, ensuring efficient and fair swaps.
By running on Arbitrum, Curvefi-Arbitrum takes advantage of the scalability and cost-effectiveness of layer 2 technology, providing users with a seamless and cost-efficient stablecoin trading experience.
When it comes to fetching trade data from Curvefi-Arbitrum, DIA follows its comprehensive approach to data management. For decentralized exchanges like Curvefi, DIA retrieves trading data directly from the blockchain by subscribing to swap events in liquidity pools.
This process allows DIA to access live trading data on Curvefi-Arbitrum in real-time. By retrieving the data directly from the blockchain, DIA can ensure its accuracy and reliability. This is particularly important in the decentralized finance (DeFi) space, where the speed and accuracy of data are crucial for making informed trading decisions.
DIA's data retrieval process for decentralized exchanges like Curvefi differs from its approach to centralized exchanges. For centralized exchanges, DIA utilizes scrapers to collect trades from exchange databases using Rest APIs or WebSocket APIs. This allows DIA to capture trading data as close to the data source as possible, ensuring high precision.
When it comes to NFT marketplaces, DIA captures live trading data by retrieving it from integrated marketplaces' smart contracts. The retrieval period for NFT data ranges from 20 seconds to 1 minute, covering all NFT transactions happening in real-time. This approach ensures that DIA provides accurate and up-to-date data from the broader NFT market.
In summary, DIA fetches trade data from Curvefi-Arbitrum by subscribing to swap events in liquidity pools on the blockchain. This allows DIA to access real-time and accurate trading data in the DeFi space. For centralized exchanges, DIA utilizes scrapers to collect trades from exchange databases, while for NFT marketplaces, live trading data is retrieved from integrated marketplaces' smart contracts.
DIA utilizes a two-step process to compute trade data from Curvefi-Arbitrum in order to build price feed oracles. The specific process differs depending on whether we are referring to a decentralized finance (DeFi) or a non-fungible token (NFT) exchange.
For DeFi exchanges, DIA starts with data cleaning and outlier detection. This step ensures the resilience of the price estimation process against irregularities such as market manipulation, errors, or flash crashes. DIA applies an Interquartile Range (IR) filter to exclude data points and sets that deviate from the acceptable range relative to the interquartile range. The remaining trades, falling into the middle quartiles, proceed to further processing.
To determine the final price, DIA applies price determination methodologies. One example is the Volume Weighted Average Price (VWAP), which considers the different volumes of trades. Trades from the queried time range are collected and weighted by their volume. The weighted average price is calculated by dividing the cumulative volume-price-products by the sum of all volumes combined.
For NFT exchanges, DIA follows a different process to determine the floor price of a collection. First, the on-chain trade data undergoes cleansing filters to exclude market outliers and manipulation techniques. Then, a pricing methodology is applied to determine the final price point.
The simplest methodology is the Floor Price, which provides the lowest sale price of an NFT collection recorded on the blockchain within a specific time window. However, this method is susceptible to manipulation. To address this, DIA offers advanced methodologies such as the Moving Average of Floor Price, which calculates the moving average of a collection's floor price. Additional customizable parameters allow for adjusting to specific use cases.
DIA also applies an interquartile range outlier detection filter to filter out malicious behavior like wash trading. They are open to discussing custom filters and methodologies for specific use cases.
It is important to note that this description specifically pertains to DIA's process of computing trade data from Curvefi-Arbitrum to build price feed oracles and does not include information about DIA's services or external sources.
Instead of distributing pre-calculated data feeds, DIA covers the whole data journey from individual trade collection, and computation to the last mile of the feed delivery.
