Block → Date to Block

AI-generated

Overview

This node operation converts a specific date to the corresponding blockchain block number on a selected blockchain network. It is useful for scenarios where users need to find the block number at or near a particular date and time, such as for historical data analysis, auditing blockchain events, or syncing data from a specific point in time. For example, a user can input a date and select Ethereum as the chain to get the block number that was mined closest to that date.

Use Case Examples

  1. Convert a date to a block number on Ethereum to analyze transactions at that time.
  2. Find the block number on Polygon for a given date to fetch NFT ownership data as of that block.

Properties

Name Meaning
Chain The blockchain network to query, e.g., Ethereum, Polygon, BSC, etc.
Date The specific date and time to convert to a block number, required input.
Additional Fields Optional parameters to customize the request, including limit of results, pagination cursor, whether to include metadata, and number format (decimal or hex).

Output

JSON

  • block - The block number corresponding to the given date
  • timestamp - The timestamp when the response was generated
  • operation - The operation performed, here 'dateToBlock'
  • resource - The resource type, here 'block'
  • chain - The blockchain network queried

Dependencies

  • Requires a Moralis API key credential for authentication to access Moralis Web3 API endpoints.

Troubleshooting

  • Common issues include invalid or missing API key, incorrect date format, or unsupported blockchain network selection.
  • Errors may occur if the date is out of range or if the Moralis API service is unavailable. Ensure the date is valid and the API key is correctly configured.
  • If the node returns 'No data found', verify the date and chain parameters and try again.
