Merge OpenAPI and Watchgod responses to track latest status of a deposit/withdraw transaction on Ethereum Chain and Polygon Chain.

Usage

Installation

npm i openapi-watchgod-merger
import openapiWatchgodMerge from openapi-watchgod-merger

// Folllowing variables represent data
// from OpenAPI and Watchgod API
const openApiDepositResponse = []
const openApiWithdrawResponse = []
const openApiBurnResponse = []
const watchGodResponse = []

// below given function expects all 4 arguments
// and in same order
const mergedData = openapiWatchgodMerge(
    openApiDepositResponse,
    openApiWithdrawResponse,
    openApiBurnResponse,
    watchGodResponse
);

Detailed Explanation

For now, it is not giving out exact intelligent status of a transaction. It just merges all related transactions into one and appends some additional information based on below given priority.

A merged transaction will have all the undisturbed response with some additional fields added.

NOTE: All fields added by this library starts with an underscore(e.g. _latestStatus)

Deposits

Deposit transactions can be tracked via 2 places with below mentioned priorities

Priority for Deposit Txs(Highest to Lowest)

  • OpenAPI
  • Watchgod

Additional fields

  • _txType
  • _txSource
  • _openapiTxStatus
  • _watchgodTxStatus
  • _latestStatus

Withdraw

Withdraw transactions consists of 2 parts(i.e. withdraw init/burn and exit). Withdraw transactions can be tracked via 2 places with below mentioned priorities

Priority for Withdraw+Exit Txs(Highest to Lowest)

  • OpenAPI Exit
  • Watchgod Exit
  • OpenAPI Withdraw
  • Watchgod Withdraw

Additional fields

  • _txType
  • _txSource
  • _burnTxHash
  • _exitTxHash
  • _openapiExitTxStatus
  • _watchgodExitTxStatus
  • _openapiBurnTxStatus
  • _watchgodBurnTxStatus
  • _latestStatus

Interface

Since different APIs uses their own names for naming a variable(e.g. openapi:transactionHash, watchgod:hash), to avoid juggling between 2 naming conventions we will be parsing some common variable names.

Interface

amount
blockNumber
data
from
network
rootToken
timestamp
to
txBurnHash
txHash
txStatus
txType
_txSource
_txType
_depositTxHash
_burnTxHash
_exitTxHash
_openapiExitTxStatus
_watchgodExitTxStatus
_openapiBurnTxStatus
_watchgodBurnTxStatus
_latestStatus

If required, to parse and unparse you can use the util methods provided by this library.

  • convertOpenapiToInterface(openapiTx)
  • convertWatchgodToInterface(watchgodTx)
  • (watchgodTx)

Usage

import {
  convertOpenapiToInterface,
  convertWatchgodToInterface,
  convertInterfaceToWatchgod,
} from "openapi-watchgod-merger";

const openapiTx = {
  /*...*/
};
const watchgodTx = {
  /*...*/
};

const parsedOpenapiTx = convertOpenapiToInterface(openapiTx);
const parsedWatchgodTx = convertWatchgodToInterface(openapiTx);

const unparsedWatchgodTx = convertInterfaceToWatchgod(parsedWatchgodTx);

Note: convertInterfaceToWatchgod will still have the additional fields added by library

OpenAPI mapping

OpenAPI Interface
transactionHash txHash
transactionStatus txStatus
depositor from
isPos isPoS
burnTransactionHash txBurnHash

Watchgod mapping

Watchgod Interface
hash txHash
status txStatus
isPos isPoS
prevBurnHash txBurnHash

Other helpful constants

Constants can also be imported for use

  • TX_SOURCE can be used with _txSource
  • TX_TYPE can be used with _txType
import { TX_SOURCE, TX_TYPE } from "openapi-watchgod-merger";

const depositTxs = (mergedTransactions) =>
  mergedTransactions.filter((tx) => TX_TYPE.DEPOSIT === tx._txType);
