Token Snapshot: Create ERC1155 Token Snapshot

Forked from erc721-snapshot

This command-line utility creates a snapshot of any ERC1155 token in JSON or CSV format. Use your own fully synced Ethereum node or any Ethereum node as a service like Infura.

  • Works without a local Ethereum node.
  • Automatically resumes the next time upon failure.
  • Tested to work with Infura.

Getting Started

npm install erc1155-snapshot -g

CLI Arguments

None. Prompts for user input and produces a configuration file on the first run.

How to Use Token Snapshot?

Navigate to a directory where you'd like to save the token snapshot to.

cd path/to/a/directory

Run the program:

erc1155-snapshot

Configuration File / Prompt Parameters

To avoid getting prompted for each configuration parameters, each time erc1155-snapshot is ran, have a ./snapshot.config.json file at the same location as erc1155-snapshot is executed.

{
  "provider": "https://mainnet.infura.io/v3/<key>",
  "contractAddress": "",
  "fromBlock": 0,
  "toBlock": "latest",
  "format": "json",
  "blocksPerBatch": 2500,
  "delay": 0,
  "checkIfContract": true
}

provider

Enter your fully synced Ethereum node. Could be a local node or remote services like Infura.

contractAddress

Address of your ERC1155 contract.

fromBlock

The block height to scan from. To save time, enter the block number of the transaction your token was created on.

toBlock

The block height to end the scan at.

blocksPerBatch

The number of blocks to query per batch.

If you are using remote service like Infura, keep this number relative low (2000-5000) to avoid rate limits. If you are using a dedicated Ethereum node, you can increase this number to suit your needs.

delay

The delay (in ms) between each request in the loop. Tweak this if you are experiencing rate limit from your provider.

checkIfContract

Checks each address to determine whether it is a smart contract or an Ethereum wallet.
