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).

We have released two new endpoints for preparing token transfers as part of our Blockchain Tools:

• Prepare A Fungible Token Transfer From Address  
• Prepare A Non-Fungible Token Transfer From Address 

Using these two separate endpoints, customers can prepare transfers for fungible and non-fungible tokens from an address with private and public keys. The address doesn’t have to belong to a wallet. The response will include the transaction fee in Wei.

What else is new:

• In the endpoint New Reverted Block we’ve added UTXO protocols as possible values. 
• In the responses of List Confirmed Transactions By Address and Get Transaction Details by Transaction Id endpoints "contract" and "input" are now optional.
• In the Prepare A UTXO-Based Transaction From HD Wallet (xPub, yPub, zPub) endpoint, the “replaceable” has been made optional (previously required) in all places.
  

Technical documentation updates:

We’ve added additional information on the paginated and list based endpoints and we’ve updated the values for API requests. 

We've also updated our Key Management System (KMS) on GitHub.

Here is what's new in our latest release:

New endpoint: Prepare Transaction From Address

Through this endpoint customers can prepare a transaction from an address with private and public keys. The address doesn’t have to belong to a wallet. The response will include the transaction fee in Wei. The API is part of Blockchain Tools.

Improvement: 

The endpoint Prepare An Account Based Transaction From HD Wallet has been renamed to Prepare A Transaction From an Address in HD Wallet (xPub, yPub, zPub) to more correctly reflect its purpose. 

We’ve also updated our Node.js SDK and our Key Management System on GitHub.

Please update your libraries if you’ve used this endpoint.

The Crypto APIs Team

We’ve added two new blockchain-specific endpoints in our Wallet as a Service that can be used to stake and unfreeze TRX for bandwidth or energy on the TRON network. We’ve also made some changes and improvements to existing endpoints. See the details below: 

New TRON-specific endpoints:

• Freeze TRON for Energy Or Bandwidth - Through this endpoint, customers can stake (freeze) the balance of a specific TRX address to obtain bandwidth or energy. The minimum amount for staking is 1 TRX. The account receiving the bandwidth or energy must have an available TRX balance.
• Unfreeze TRON Energy Or Bandwidth - With this endpoint, customers can unfreeze already staked TRX to receive resources. When unstaking bandwidth or energy, the whole amount for that resource will be released to the specified receiver address. The request for unfreezing TRX can be done 3 days after the staking transaction.

Improvements to existing endpoints:

• Prepare A UTXO-Based Transaction From HD Wallet (xPub, yPub, zPub) - In this endpoint, the replaceable attribute has been made optional when creating a request. 
  
• Derive HD Wallet (xPub, yPub, zPub) Change Or Receiving Addresses - In this API we’ve added base58 as a possible value for addressFormat for TRON.
• Sync New HD Wallet: More blockchains have been added as possible values. Customers can now sync Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Ethereum, Zcash, Ethereum Classic, BNB Smart Chain and XRP. 
  

Stay tuned with our updates page to be the first one to learn what's new with Crypto APIs! 

We've added some new features and provided support for more blockchain protocols to existing API endpoints.

Here is what's new:

List Unspent Transaction Outputs By Address - we've added a new response attribute isAvailable. Through this endpoint customers can list their transactions' unspent outputs by address.

Prepare An Account-Based Transaction From HD Wallet (xPub, yPub, zPub) - we've added a new response attribute unit. Using this API endpoint users can prepare a transaction for signing from a synced with Crypto APIs address from the specific xPub. 

Derive And Sync New Change Addresses - we've expanded the support for more blockchains in this API and customers can now use it with Bitcoin Cash, Litecoin, Dash, Dogecoin and ZCash. 

Derive And Sync New Receiving Address - we've added more supported blockchains in this API endpoint and customers can now use it also with Bitcoin Cash, Litecoin, Dash, Dogecoin, ZCash, XRP, Tron and Ethereum Classic.
