Introduction to Parsed
Parsed is a specialized tool designed for interacting with and analyzing blockchain data using DuneSQL, an optimized query language based on TrinoSQL. Parsed's primary function is to decode blockchain data, such as transaction logs and smart contract events, into a more human-readable format. This is achieved by extracting, transforming, and converting complex byte arrays and hexadecimal values from blockchain logs, making it easier for users to retrieve and analyze on-chain data. For example, users can decode Ethereum transaction logs to extract information about transfers, events, or contract interactions, then present this data as structured tables. Parsed’s approach simplifies working with raw blockchain data by offering custom SQL functions, such as `bytearray_to_uint256` or `bytearray_substring`, which help in extracting and converting on-chain data segments.
Main Functions of Parsed
Decoding Blockchain Logs
ExampleA user wants to decode an Ethereum transaction log to extract values like token addresses, sender/receiver addresses, and transfer amounts. Parsed uses functions like `bytearray_substring` to extract specific byte positions and `bytearray_to_uint256` to convert values from hexadecimal to decimal format.
ScenarioFor example, decoding a log related to an ERC20 token transfer where the log data contains the sender address, receiver address, and the amount of tokens transferred.
Handling Large Numeric Types
ExampleUsers can cast large numbers, such as those in `uint256` format, by using Parsed’s built-in `bytearray_to_uint256` or arithmetic operations like addition, subtraction, or multiplication on blockchain-related data. This helps in decoding large amounts or balances stored in smart contracts.
ScenarioFor example, calculating the total value transferred in a DeFi application using `uint256` formatted token values extracted from Ethereum smart contract logs.
Querying Multiple Blockchain Chains
ExampleUsers can query and decode data across multiple blockchains, including Ethereum, Arbitrum, Optimism, and others. Parsed facilitates queries on different networks by utilizing DuneSQL’s optimized query capabilities and abstracted tables.
ScenarioA user analyzing cross-chain bridge transactions can decode and compare logs from both the Ethereum mainnet and a Layer 2 solution like Optimism, extracting common elements such as sender, receiver, and token amounts.
Ideal Users of Parsed
Blockchain Data Analysts
Analysts working with large datasets from blockchain networks will benefit from Parsed’s ability to extract, decode, and manipulate transaction logs and smart contract events. The built-in support for handling large numerical data types and byte arrays simplifies analysis, allowing analysts to retrieve meaningful insights from raw blockchain data.
DeFi Developers and Researchers
DeFi developers and researchers working on decentralized financial applications can use Parsed to decode and analyze on-chain financial transactions, token swaps, liquidity pool activities, and more. The ability to retrieve data across multiple chains helps in understanding cross-chain liquidity flows and building robust DeFi protocols.
