Streaming API Launch!

The GoldRush Streaming API is now available in public Beta! It provides real-time updates on blockchain events, including:

• Token balances
• New DEX pairs (on Uniswap V2, V3)
• Wallet activity
• OHLCV token and pair price data.

This API is ideal for applications that require immediate notifications or updates on blockchain activities such as:

• Trading bots
• Gaming
• AI agents

The API is offered via GraphQL endpoints allowing developers to filter for specific chains, or DEXs and to start real-time subscriptions.

Note: The GoldRush Streaming API is currently in Beta. It is stable for testing and evaluation but may undergo changes in schema or behavior as we continue to improve it. No API credits are currently charged.

We welcome your feedback so please reach out to us directly to report issues or request features.

Enhanced Token Spam Lists

With the release of the Enhanced Spam Lists for ERC20 tokens and NFTs across all Foundational Chains, the following GoldRush APIs are now seamlessly updated to leverage these lists:

• Get token balances for address using the no-spam query parameter.
• Get historical token balances for address using the no-spam query parameter.
• Get NFTs for address using the no-spam query parameter.

In addition, any of the API responses with the is_spam field will incorporate the Enhanced Spam Lists.

​

Update to Token Holders API

The following changes were made to the Token Holders API:

• When no block-height is specified, the response is from the latest token holder snapshot that is updated every 30 minutes. This results in a fast response time.
• To fetch the current token holders list without using the snapshot, set no-snapshot=true. This bypasses the cache and is dynamically calculated at request time.

The snapshot exists for the top 100 tokens on each Foundational Chain as listed on CoinGecko.

This modification is to help address the two unique use cases for this API:

1. Displaying a list of token holders on leaderboards to provide guidance on a token’s distribution. This list does not generally need to be accurate to the minute.
2. Token holder lists for reward distributions and token gating. This is generally an accurate token list generated at a specific point in time.

GoldRush Changes Phase 1: Chain Classification & Prioritization

GoldRush is reorganizing its support for various chains by grouping them into four 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 and will will offer core APIs including balances, transactions, and decoded log events.

Archived Chains: No live data will be available for archived chains. Only historical data will continue to be provided for a brief period of time.

New Multichain & Multiaddress Transactions API

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.

Cached NFT Thumbnail Data Added

We just majorly updated our NFT endpoints with new cached thumbnail data!

This update includes several key fields: thumbnails, which provide various sizes of asset thumbnails like image_256, image_512, image_1024, and image_opengraph_url, tailored to different use cases including OpenGraph protocol; image_preview, an unmodified thumbnail of the asset; and asset_properties, detailing dimensions and the dominant color of the asset.

Devs can also benefit from the thumbhash feature, which allows for the decoding of thumbnail hashes into a blurred image preview, useful for enhancing loading experiences and privacy in NFT galleries and marketplaces.

This suite of enhancements supports a wide range of asset types, from images and videos to audio files, catering to diverse NFT displays.

​

Current NFT Owner Data Added

We’ve added a current_owner field to our NFT ownership endpoints:

• Get NFTs from contract with metadata.
• Get single NFT with cached metadata from contract.

The current_owner field gives you the wallet address of the current owner of that NFT. This new feature applies to all chains with NFT support.

​

New Viem-Compatible Client SDK

We now offer The Covalent Viem SDK, developed in TypeScript, which leverages the viem framework to offer a seamless integration path with the GoldRush API.

​

Introducing GoldRush Decoder: Decode, Visualize, Understand

In November 2023, we launched GoldRush Kit, a series of customizable React components for dApp frontends. Now, we introduce GoldRush Decoder, a transformative tool that translates raw log events from blockchain transactions into structured, human-readable formats.

GoldRush Decoder pairs directly with GoldRush Kit for easy visualization, however, it can be used as a standalone tool.

Traditional block explorers keep their data transformations private and inaccessible to users. GoldRush Decoder is different. This open-source tool acts as a public good for decoded data.

​

New Gas Parameter in Transaction Summary Endpoint

We recently added a new with-gas query parameter to the Get transaction summary for address endpoint.

This endpoint is commonly used to fetch the earliest and latest transactions, and the total transaction count for a wallet. The new with-gas parameter allows you to see the total gas quote for the wallet, as well as the average quote per transaction, and other insightful metadata.
