We're excited to announce that the Avalanche blockchain is now supported by our "Get Fee Recommendations" endpoint. This addition allows users to receive real-time fee recommendations based on mempool data, providing more accurate and timely insights than those based on mined fees.

We're thrilled to announce the addition of Optimism, Arbitrum, Avalanche, and Base blockchains to two of our most used blockchain infrastructure endpoints: internal transactions and token transfers. These endpoints offer insights into token transfers and internal transactions, providing greater control, transparency, and clarity.

Endpoints Overview

1. List Token Transfers by Transaction Hash

This endpoint provides a detailed breakdown of all token transfers linked to a specific transaction hash. This can now be performed across all new four blockchains - Optimism, Arbitrum, Avalanche, and Base.

2. List Internal Transaction Details by Transaction Hash

Access detailed information on internal transactions within a particular transaction hash, now available for Optimism, Arbitrum, Avalanche, and Base networks.

Key Benefits Of The Two Endpoints

- Detailed Token Tracking: Gain complete visibility into token movements within a specific transaction.

- Deeper Transaction Insights: Understand the inner workings of transactions on Optimism, Arbitrum, Avalanche, and Base networks. - Boost Development Efficiency: Enhance your ability to build and optimize applications based on these four leading blockchain platforms.

We’re excited to introduce two new endpoints for the Optimism, Base, and Arbitrum blockchains. These endpoints provide customers with real-time fee recommendations based on mempool data, delivering more precise and timely insights compared to those based on mined fees.

Explore the newly supported fee endpoints for Optimism, Base, and Arbitrum:

• Get EIP 1559 Fee Recommendations

• Get Fee Recommendations

Additionally, we’ve expanded our Node-as-a-Service (NaaS) supported networks to include testnets for Avalanche, Optimism, Base, and Arbitrum. This integration allows developers to test and build on these networks.

We're excited to announce the launch of two new endpoints for the Polygon blockchain! These endpoints provide deeper insights into token transfers and internal transactions, giving you more control and transparency.

New Endpoints

List Token Transfers by Transaction Hash: This endpoint retrieves details for all token transfers associated with a specific transaction hash on the Polygon blockchain.

List Internal Transaction Details by Transaction Hash: This endpoint allows you to access detailed information about internal transactions within a specific transaction hash on Polygon.

Benefits:

• Gain a comprehensive view of token movement within a transaction.

• Understand the internal workings of a transaction on the Polygon network.

• Enhance your development capabilities for Polygon-based applications.

On 2nd April, Crypto APIs added the Polygon blockchain to its suite of supported networks, which was available to early adopters. As of Monday, 8th April, Polygon status was changed to publicly accessible through various endpoints which we listed below, available for deployment by all clients.

We are currently supporting Polygon across two of our core services: Blockchain Data and Blockchain Events. Through Crypto APIs, customers can access fully-indexed real-time and historical data up to 14 days old. Additionally, upon request, we can retrieve and provide older data dating back to the genesis block via our endpoints.

All endpoints that are currently supporting Polygon are as follows:

Blockchain Data Get Address Balance
List Confirmed Tokens Transfers By Address
List Confirmed Transactions By Address
List Internal Transactions By Address

Blockchain Events

New Confirmed Coins Transactions

New Confirmed Coins Transactions And Each Confirmation

New Confirmed Tokens Transactions

New Confirmed Tokens Transactions And Each Confirmation

New Confirmed Internal Transactions

After a long pause, the Node As A Service (NaaS) has been relaunched on Wednesday, 17th January 2024. This service is now open to the public as an integral component of Crypto APIs services.

New Blockchains Added:

All previously integrated blockchain networks are supported. In addition, our latest additions of integrated chains to NaaS are including Polygon, Arbitrum, Optimism, Solana, Fantom, Near and Filecoin. 

Shared Nodes Only:

Our service currently empowers customers with the advantages of shared nodes, ensuring a seamless and enhanced experience. We are offering a new level of performance through the availability of our shared node capabilities. Dedicated nodes are also available per individual request. 

We are releasing several improvements, affecting the “Get Transaction Details By Transaction ID” and “List Tokens Transfers By Transaction Hash” endpoints. In addition, two new endpoints “List Synced HD Wallets” and “Activate HD Wallets” have been introduced and are now available for integration as part of our blockchain suite.  

Get Transaction Details By Transaction ID

As part of our planned upgrades we have added to the Binance Smart Chain (BSC) protocol a “Transaction Status”. Customers can now obtain data about transactions that occurred on the protocol, and more specifically get information on their transaction unique identifiers.   

List Tokens Transfers By Transaction Hash

Through this endpoint, our customers can receive data about transactions, including details on whether transactions are validated on the blockchain. Our update added the “Token ID” attribute to the endpoint, allowing receiving information for non-fungible tokens (NFTs) about their unique identifier code 

List Synced HD Wallets - new endpoint

This endpoint allows our customеrs to list all of their synced wallets and delete them. Via pagination getting up to 50th results in a single page.

Activate HD Wallet - new endpoint

Customers can choose to initiate a one-off synchronization for their HD wallet in case of payment delays or subscription plan downgrades due to insufficient payments. Upon re-subscribing to our services the new endpoint will allow to re-activate synchronization for their hierarchical deterministic wallet(s).

What`s New?

Two new blockchain networks have been added to our infrastructure and we are now supporting

• Tezos blockchain
• Stellar blockchain

We released a new API versioning allowing generation of new endpoints. Find more details on Crypto APIs API versioning here
