Crypto APIs Build Crypto & Blockchain products faster

  • Global Issue with BSC network gas fees


    Reported on Wednesday, March 27th, a global issue impacting all users of the Binance Smart Chain protocol was identified. Some users encountered and may continue to encounter failed transactions while attempting to send Binance Smart Chain BNB or BEP20 tokens. 

    The problem with the BSC network arises from all global node elastic pools reverting fees lower than the minimum required, leading to the error message: "-32000: transaction underpriced: tip needed 3000000000, tip permitted...". BSCScan, the primary block explorer for the BSC network also displays wrong gas values оn the different priority transaction options as a result of the issue, which can be seen below:

    Although the issue remains unresolved globally, Crypto APIs have identified a solution, ensuring uninterrupted usage of the BSC network for our users. If you encounter any difficulties, kindly reach out to our support team at [email protected] for assistance.

  • Sepolia Testnet Is Now Supported


    The Ethereum Sepolia Testnet has been integrated into the Crypto APIs suite as a supported network. This integration was finalized on Thursday, March 7th, 2024, and Sepolia is now available across all of our services.

    What happens with Ethereum Goerli?
    We would like to inform our users that Ethereum Goerli has been replaced by the Sepolia testnet and will no longer be supported. This decision aligns with the official announcement stating that the Goerli network will be deprecated in April 2024.

  • Service Optimization Updates & Release Of Two New Endpoints For HD Wallets

    New Feature Improvement Announcement KMS

    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 :new:

    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 :new:

    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).

  • New Endpoint Is Added To Crypto APIs


    A new endpoint has been added to Crypto APIs along with new added attributes for Ethereum. Please see below for further information:

    "signatureData": {

                        "functionSignature": "_SIMONdotBlack_(int8[]. int224[])",

                        "method": "_SIMONdotBlack_",

                        "signature": "0x095ea7b3"
