Safle Transactions Controller

This SDK returns the list of all the transactions done by a particular address. The transactions include both incoming and outgoing transactions. Also provided is a functionality to convert the unreadable EVM transaction data to human readable one.

Installation

To install this SDK,

npm install --save @getsafle/transactions-controller

Initialization

Initialize the constructor,

const safleTransactionsController = require('@getsafle/transactions-controller');

const transactionsController = new safleTransactionsController.TransactionController();

Get incoming transactions

This function returns the list of all the incoming transactions.

const incomingTransactions= await transactionsController.getIncomingTransactions({ address, fromBlock, network, apiKey });

• address - user wallet public address,
• fromBlock - Start block number
• network - ethereum network selected/ chain selected
• apiKey - etherscan/polygonscan api key(based on the network selected)

Get outgoing transactions

This function returns the list of all the outgoing transactions.

const outgoingTransactions= await transactionsController.getOutgoingTransactions({ address, fromBlock, network, apiKey });

• address - user wallet public address,
• fromBlock - Start block number
• network - ethereum network selected/ chain selected
• apiKey - etherscan/polygonscan api key(based on the network selected)

Get all transactions

This function returns the list of all the transactions on an address (incoming + outgoing)

const transactions= await transactionsController.getTransactions({ address, fromBlock, network, apiKey });

• address - user wallet public address,
• fromBlock - Start block number
• network - ethereum network selected/ chain selected
• apiKey - etherscan/polygonscan api key(based on the network selected)

Analyze Transactions

This function accepts an EVM transaction hash and analyzes the transaction to output human readable values.

const result = await transactionsController.analyzeTransaction(transactionHash, rpcUrl, network);

• transactionHash - The transaction hash for the transaction to be analyzed.
• rpcUrl - RPC URL of the chain of the transaction hash passed.
• network - Network to be used to query the safleId. valid inputs - mainnet or testnet

Get Transaction Type

This function returns the type of transaction based on the contract function called.

const transactionType = transactionsController.getTransactionType(functionInput, rpcUrl);

• functionInput - The function name and the input parameter datatype in string format. eg. transfer(address, uint256).
• rpcUrl - RPC URL of the chain of the transaction hash passed.

Chains supported

• ethereum
• polygon
• bsc
