Products
We offer a variety of products and tools which will help you easily build your Blockchain and Crypto product.
Wallet as a Service
Managed Transactions
No need to take care of fees calculation or UTXO, etc. We take care of it for you.
Transactions Limits
You can set limits: per transaction, per hour and per day, so no matter what happens your funds will be safe.
Manual Approvers
You can invite and select as many manual approvers as you want. The transaction will never happen if they don't log in to our dashboard and approve it manually.
Authorized IPs
You can authorize certain IPs in order to create transactions. This adds AN additional layer of security as we will not accept any request outside of your IPs list.
Deposit Notifications
You can activate notifications for your wallet so that you get a callback for every deposit made.
Manual Rejecters
You can set as a many manual rejecters as you prefer. This is helpful in situations when the transaction is too large or too sensitive and you need to know that it is being thoroughly inspected and can be rejected if necessary.

Blockchain Data
Unified Data
Unified data is a new way of representing blockchain data. Invented by Crypto APIs 2.0, the idea is to always have the exact same request and same response no matter the Blockchain. The integration is done in hours and adding new blockchains no longer needs any extra effort.
Raw Data
In addition to Unified Data, we also provide the generic raw data. It's what blockchain nodes have when no changes have been made from our side. It's useful in the cases when you want to replace your node or service provider with us, but at the same time you don't need to make any changes to the code. Unlike Unified data, we have to note that here every blockchain has its own specific structure of data.
REST APIs & WebSockets
In addition to REST APIs, you can get some of the data using WebSockets. WebSockets will return only raw data, and will simulate exactly what a node can push in general.
Mempool Data
Mempool data is very important as tens of thousands of pending transactions are fighting to be mined in the next block. Every transaction wants to be confirmed as soon as possible using the lowest fee possible.
HD Wallets (xPub, yPub, zPub)
In addition to Blocks, Addresses, Balances, Transactions, Uncles, Smart Contracts, Tokens Transfers, Internal Transactions, Logs, etc., we also provide unified endpoints for syncing HD Wallets (xPub, yPub, zPub). Once synced, you can get balance, transactions and addresses.
Analytics & Insights
Number of active addresses, number of blocks, transactions in different blocks, average fee data, and much more.

Blockchain Events
Unified Requests
One of the biggest benefits here is that we provide 100% unified requests, which means no matter of the blockchain or network, you can always use EXACTLY the same request to create a subscription. You have to integrate it only once no matter of the supported blockchain protocol number.
Unified Callbacks
The Callback structure depends on the event time. Still, no matter of the blockchain and network you will always receive exactly the same callback structure for the same event type.
Multiple Events Types
You can create subscriptions for different events such as: new block, new confirmed transaction, new unconfirmed transaction, new tokens transfer, new internal transaction, changes in fees, a transaction with an amount higher than another certain amount, etc.
Secured Callbacks using Signature
You can add "callbackSecretKey" to your request which will indicate to our team that you want us to add a signature to our callbacks. It's a much needed feature to ensure your application that the callback really comes from Crypto APIs 2.0, and not from somewhere else.
We use "HMAC_SHA256" to create a signature, which is set in our post header as "X-Signature".
Verified Domains & Retry Logic
We don't allow users to create a subscription before they verify their domain. Once approved, you can then use it in the callbackURL parameter. However, in case we post our request to the callbackURL and you don't accept it properly (there is no 200 status code as a response), we will try to resend it again up to 5 times.
Idempotency Support
Our callbacks support idempotency for safely retrying requests. This way we ensure the same operation won't be accidentally performed twice. For instance, if we send you a callback about an incoming transaction and it does not respond due to a network connection error, we will retry the request with the same idempotency key to guarantee that no more than one incoming transaction is registered on your side.

Blockchain Automations
Automatic Coins Forwarding
By creating such automations we start monitoring your address for incoming coins. Once they are received we automatically move all of them to your target address. It works exactly in the same way for absolutely all supported blockchain protocols.
Automatic Tokens Forwarding (Ethereum ERC20 Tokens)
You can automatically forward a specific ERC20 token (Tether USD) from any of your deposit addresses to your main address.
Automatic Tokens Forwarding (Bitcoin Omni Layer Tokens)
You can automatically forward a specific Omni Layer property (TetherUS) from your deposit addresses to your main address.
Priority selection to optimize fees cost
Since you don't know when exactly you would be receiving funds and fees are frequently changing, you can't set an exact fee but you can set the priority of your automations (slow, standard, fast) and we will take care of it. Our fee calculation is based on Mempool data.
Minimum Amounts
You can set a minimum amount to be collected before forwarding, which will save you some fees as we will not forward any amount automatically. Our bot will wait till the minimum amount is collected and after that will forward the funds as a single transaction.
Fully Automatic
In case your fee address is out of funds and there are some incoming transactions, they will not be forwarded. Once you fill up your fee address all pending token automations will be automatically triggered.

Blockchain Tools
Deriving HD (xPub, yPub, zPub) receiving addresses
You can derive HD receiving addresses where we will return xPub, yPub, zPub, seed, etc. and never save any of the data on our side.
Deriving HD (xPub, yPub, zPub) change addresses
You can derive change addresses from a certain HD wallet no matter of the address format.
Decode a Raw Transaction
Decode raw transactions without propagation. Double-check another client library or confirm that another service is sending the proper transactions.
Broadcast signed transaction
In case you want to locally sign transactions on your side, in the case you have a hardware wallet, or you don't want to share the private key with anyone, you can use this feature to eliminate the need of having your own node.
Validate Addresses and Check Formats
Validate certain address and easily check its format/type by using our endpoints.
Prepare Transactions
Preparing a transaction is not an easy task especially in UTXO based blockchains like Bitcoin. By using our endpoints we can help you make your life much easier without affecting the security of your funds.
