Crypto APIs Build Crypto & Blockchain products faster

  • New endpoints, event type and improvements

    New Feature Improvement

    We are pleased to announce the launch of more new endpoints for interacting with blockchain protocols and getting notified for anything that happens on-chain.

    Here is what’s new:

    Wallet as a Service: Create New Master Wallet

    Through this endpoint customers can easily create a new Master Wallet through the API. The user provides the desired Wallet name and in return the response includes the walletId. 

    When creating a wallet, the customer can select whether to create a Testnet or Mainnet wallet. That new Wallet can be additionally also backed up through the Crypto APIs Dashboard. 

    Improvement: XRP has been as a possible value to endpoint "Create Coins Transaction From Address for Whole Amount"

    Blockchain Webhooks: New Reverted Block

    We are introducing a new event for reverted blocks. By subscribing to this event, customers will receive callbacks from Crypto APIs every time when a block is reverted on a specific blockchain. Reorganization can happen in cases when two blocks are mined at the same time and the nodes cannot agree on which one was first. This occurs as part of the chain reorganization process.

    The endpoint works for Ethereum, Ethereum Classic and BNB Smart Chain (testnet).

    Stay tuned fore more updates!

  • Official deprecation of Ropsten

    As per official information the Ethereum testnet network Ropsten will be deprecated on October 5th 2022.

    To comply with the change a modification has been undertaken for all Crypto APIs products to start using only Goerli as an Ethereum testnet network.  As of now Crypto APIs has stopped supporting the Ropsten network.

  • Ethereum Mainnet Merge to Proof-of-Stake Completed


    The Ethereum mainnet transition to Proof-of-Stake has been successfully completed. The migration happened today, September 15, 2022, after the blockchain reached a terminal total difficulty of 58,750,000,000T at 06:43 UTC.

    All of Crypto APIs products and services are operating flawlessly and we are not experiencing any issues or downtime. 

    Our team has validated the seamless synchronization of data for all of our API endpoints and the Merge is not expected to impact your daily operations. 

    We continue monitoring the network performance and we will update you if necessary.

  • Preparing for the Ethereum Merge: Bellatrix Upgrade Announcement


    The Ethereum Merge to proof-of-stake ("PoS") is just around the corner.

    We have upgraded our Ethereum nodes to the latest Bellatrix upgrade in advance to ensure the smooth operations of our customers. You don’t need to do anything on your end and no issues or downtime are expected. 

    Bellatrix is a consensus layer upgrade that is set to occur when the Beacon Chain reaches an epoch height of 144,896, around 11:34:47am on September 6, 2022 (UTC).

    Another upgrade on the execution layer, Paris, will be triggered by a specific Total Difficulty threshold called the Terminal Total Difficulty (TTD) with a value of 58750000000000000000000, expected around September 15, 2022 (UTC). 

    This will mark the official Merge and Ethereum’s transition from proof-of-work to proof-of-stake.

    Stay tuned for more updates on the Merge and our product suite.

    What is Crypto APIs KMS?
    The Crypto APIs KMS is a self custody solution for generating and storing of private keys.  It is an open-source Node.js library providing full control over master private keys, master seeds, and mnemonics. It allows you to create HD wallets (xPubs) and sign transactions locally without a network connection (offline).
    The KMS can be used in combination with Crypto APIs product suite for syncing xPub, deriving wallet  addresses, listing wallet addresses, getting fee recommendations, preparing the transaction with the  right data, broadcasting locally signed transactions.
