🦊 tinyfox
Simple lightweight data aggregator for Transfer/Approval events of ERC20 and ERC721 tokens
Npm install tinyfox
How to use (In NodeJS)
(Requires a MongoDB to be installed on the local machine)
this.tinyFox = new TinyFox()
await this.tinyFox.init({suffix: 'development'})
let tinyfoxConfig = {
contractType: 'ERC20',
contractAddress: '0xab89a7742cb10e7bce98540fd05c7d731839cf9f' ,
startBlock: 1316824,
courseBlockGap: 1000,
fineBlockGap: 50,
indexRate: 10000,
updateBlockNumberRate:60000
}
this.tinyFox.startIndexing( this.web3, tinyfoxConfig )
this.tinyFox.stopIndexing()
this.tinyFox.resetState()
As tinyfox indexes, it starts at 'startBlock' and is collecting events at a pace of 'courseBlockGap' blocks read per 'indexRate' of time.
It stores these events inside of a mongo database named 'tinyfox_{{suffix}}' and inside of a collection named 'event_data'
Once tinyfox synchronizes to the front of the blockchain data (current state) then it will use the 'fineBlockGap' to remain synchronized.
As tinyfox is scraping chaindata for the ERC20/ERC721 token, it is also building a cache of user balances in the tables named 'erc20_balances' and 'erc721_balances'.
Events Supported
ERC20 Events: Transfer, Approval, Deposit (weth), Withdrawal (weth), Mint (0xBTC)
