GoldRush Changes Phase 1: Chain Classification & Prioritization

Published on: November 17, 2024

GoldRush is reorganizing its support for various chains by grouping them into three distinct categories:

Foundational Chains: These are the top EVM-compatible chains that have achieved wide adoption. For these chains, GoldRush guarantees product parity across its entire suite of features. This includes tracing enhancements, historical token balances, token holders, and cached NFT assets. In addition, we’ll provide ecosystem support in the form of API credits, hackathon bounties, workshops, guides, and co-marketing activities.

Frontier Chains: These chains, both EVM and non-EVM compatible, represent the cutting edge of blockchain innovation. While not all product features will be available for Frontier Chains, GoldRush will continue to offer its core APIs at an enterprise level, along with ecosystem support.

Community Chains: These chains include those with passionate builder communities as well as chains that are entering an archival phase. For these, GoldRush will maintain historical data access while limiting live data support.

New Multichain & Multiaddress Transactions API

Published on: October 17, 2024

Introducing the new GoldRush Multichain & Multiaddress Transactions API where you can fetch transactions for up to 10 EVM addresses across 10 EVM chains with one API call.

Some key points to note:

  • The pagination method used for this API are cursors . Note the response includes the following cursor specific fields:

    • cursor_before
    • cursor_after The values of these fields can be passed as query params to scroll through the transactions using before={cursor_before} or after={cursor_after}

  • If cursor_before=null , you’ve reached the first page of the descending transaction list

  • Cursors are linked to the list of chains that transactions are fetched from. If, for example, you obtain a cursor_before value when querying chains=1,56 and then try to use that value with chains=1,137 , you will get an error.

  • ALL supported chains can be passed in the chains= query param (both chain names and ID’s are supported) up to a maximum of 10 chains.

  • When no chains are specified, the API defaults to use the Foundational Chains.

NFT Asset and Metadata Caching for Arbitrum and Optimism

Published on: June 27, 2023

Often, NFT token metadata and assets are tucked away off-chain, hidden behind APIs with strict rate limits, presented in non-uniform formats, and bundled with oversized files – not to mention the lack of thumbnails and unoptimized images.

Covalent simplifies this process by downloading and caching the metadata, assets, and related information to create a smooth developer experience.

So far, we’ve cached over 100 million assets between Ethereum, Polygon and BNB. Now, we’ve started the process of crawling Arbitrum and Optimism. Monitor the progress on our data coverage page below!

DEX events

  • add_liquidity
  • pair_created
  • remove_liquidity
  • swap

Lending events

  • borrow
  • deposit
  • flashloan
  • liquidation
  • repay
  • withdraw

​
New Premium Wallet Activity Endpoint

Published on: May 24, 2023

For wallet apps, making multiple API calls to see if an address has activity on a certain blockchain is costly and inefficient.

  2. Get earliest transactions for address - This endpoint gives all the decoded details of the very first transaction by a wallet on a chain. From there you can use the next URL to continue bulk fetching the transaction history.

​
New Approvals Endpoint

Published on: May 15, 2023

Covalent has released a new approvals endpoint that shows you all the approvals across all token contracts categorized by spenders for a wallet’s assets.

This new endpoint shows you the value of assets at risk for a wallet. Basically, if the spender were to be hacked, the value at risk is how much they could stand to lose.

Get approvals is currently available on Ethereum, BNB Smart Chain and Polygon and will be added to all remaining supported networks in a few weeks!

NFT Spam Field Added

Published on: May 9, 2023

We added an is_spam field to the following endpoints:

This field returns true if an NFT is part of a collection that is flagged as spam, and is useful for filtering out spam NFT data, protecting users from interacting with scammy or fraudulent tokens, and overall improving user experience.

This field is currently supported on Ethereum and Polygon and will soon be expanded to more chains.

​
New Pretty Value Quotes

Published on: May 8, 2023

If you’ve used the Covalent API to fetch balances or transactions before, you’re probably familiar with the quote field which denotes the value of token amounts in fiat currency. The default currency is USD, but developers can change this with the query parameter quote-currency!

This month, we augmented this already-popular feature to include additional “pretty” quotes, which come with a dollar sign ($) and rounded decimals. This makes it even easier to build user-friendly interfaces, minimizing data transformations for developers.

You can find pretty_quote, pretty_gas_quote, pretty_quote_24h and pretty_value_quote throughout all relevant Class A endpoints!

Covalent Soft-Launches Premium API with Select Users

Published on: December 29, 2022

The Premium tier is available for users who want to scale with us. The Covalent Unified API has always been free and will always have a free tier. We believe in making data easily accessible, but that has led us to rate limit this shared resource to maintain a good experience for everyone. In the Premium tier, we are adding updated endpoints with faster and more reliable engines in the backend, allowing us to support higher RPS and a higher volume of requests.

The launch of the Covalent Premium API exclusively features our most popular endpoint: Get token balances for address on the Ethereum blockchain, and is currently only available to select users. In 2023 the Premium API will go public and include multiple upgraded endpoints.

New Balances Engine Complete

Published on: November 29, 2022

Covalent’s Get token balances for address endpoint has long been a favourite of our developer community. This year, we rebuilt the entire backend engine powering this endpoint in order to support our rapidly growing user base and their applications. In November, we completed QA testing and seemlessly made the switch from balances_v2 to balances_v3. This is the first of many upgrades to our existing endpoints in order to build for scale, and the next release will be transactions.

​
New Chain Name Feature

Published on: September 29, 2022

We added a feature that allows users to pass in human-readable, non-numeric chain IDs -these are chain names. For example, instead of specifying chain_id as 1 for Ethereum Mainnet, users can now use the chain-name: eth-mainnet. This feature becomes helpful when chain IDs become particularly large and/or hard to remember in cases like Palm (11297108109) and Harmony (1666600000).

To get the network name to use for the chain_id, refer to the name field of the Get all chains endpoint response.

We’ve also updated our Get transactions for address endpoint with a pagination improvement. Previously, this endpoint would timeout for addresses with too many transactions. Now the user can specify the page-number parameter with small values and the endpoint will successfully retrieve those transactions.

Additionally, we fixed an issue where the fees_paid field was null in the Get a transaction and Get transactions for address endpoints’ response.
