API
Overview
This documentation describes how to connect to and use Blocknative's transaction monitoring service using webhooks. The service delivers near real time notifications of Ethereum and Bitcoin transaction state changes via POSTs to your URL (webhook). Each state change is a JSON payload with all the transaction details.
To use our API with web sockets, please see the SDK.
API usage has rate limits. Please see Rate Limits for more details.
Create a Blocknative account by clicking the Sign up button on Mempool Explorer and following the instructions. Account creation requires email confirmation to complete.
Blocknative will create a Default API key for your account that you can use. You can create additional API keys from your account page on explorer.blocknative.com/account by clicking the Add new API key button to the upper right.
Create a new webhook for an API key by clicking the "Add a Webhook" button to the right of the API key. This will reveal a form to enter the webhook specifics: URL, blockchain (currently Ethereum and Bitcoin are supported), and network. See below for Supported Networks. You can optionally include a username and password if your webhook used basic authentication.
We support Slack webhooks. If you want to create a Discord webhook, append /slack to the end of the Discord URL to use its Slack compatibility mode.
Slack webhooks must begin with https://hooks.slack.com/services. Discord webhooks must begin with https://discordapp.com/api/webhooks.
Slack and Discord limit the size of messages so notifications involving large contract inputs may be abbreviated. Normal, i.e. not Slack/Discord, webhooks are not abbreviated.
Add an address to watch by clicking the Watch Address button and entering the address.
Ethereum addresses begin with a 0x followed by 40 characters (hexadecimal). Any valid Ethereum address can be used, including external accounts and smart contracts.
The following Bitcoin addresses are valid:
Address Type | Example |
Pubkey hash (P2PKH address) |
|
Script hash (P2SH address) |
|
SegWit Pay 2 Witness Public Key Hash (P2SH-P2WPKH) |
|
SegWit mainnet (P2WPKH address) |
|
SegWit Testnet (P2WPKH address) |
|
SegWit mainnet (P2WSH address) |
|
SegWit Testnet (P2WSH address) |
|
Testnet pubkey hash |
|
Testnet script hash |
|
To stop notifications for an address, use the View Address button next to Add webhook, and click the Delete icon next to the address you'd like to stop watching.
It is safe to add the same address multiple times or to unwatch addresses not being watched.
No authentication is currently required to facilitate testing. Basic auth (username/password) is supported and recommended for production use, and we are adding additional authentication methods based on customer requirements. We recommend HTTPS requests but also offer support for HTTP.
See how to setup a Slack webhook in this screencast:
postAdd transaction to watch
POST individual transaction hashes to watch for state changes (mempool and chain confirmation). For each transaction, specify your API key, the transaction hash or txid to watch, the transaction's blockchain (currently ethereum and bitcoin are supported), and the network to watch (see supported networks below).{
"apiKey": "<api-key>",
"hash": "<transaction-hash (ethereum)>",
"txid": "<txid (bitcoin)>"
"blockchain": "ethereum",
"network": "main"
}{"msg": "success"}
Response body will describe nature of request failure.​Examples:XYZ is not a valid apiKey(string `hash` or `txid`) XYZ is an invalid transaction hash / txid(string `blockchain`) XYZ is not supported(string `network`) XYZ is an invalid network
apiKey is the API Key created from Setup API Key step above.
hash is the transaction hash to watch. (ethereum only)
txid is the transaction id to watch (bitcoin only)
blockchain is the blockchain system to monitor. ethereum and bitcoin are supported at this time.
network is the Blockchain network to monitor for the specified transaction hash. See below for Supported Networks.
Example curl call:

{
"apiKey": "<api-key>",
"address": "<account-address>",
"blockchain": "ethereum",
"networks": "main"
}{"msg": "success"}
Response body will describe nature of request failure.​Examples:XYZ is not a valid apiKey(string `address`) XYZ is an invalid ethereum address(string `blockchain`) XYZ is not supported(array `networks`) ["XYZ"] contains an invalid network
apiKey is the API Key created from Setup API Key step above.
address is the external account address to watch.

Bitcoin
curl -X POST -H "Content-Type: application/json" -d '{"apiKey":"<api-key>","address":"<account-address>","blockchain":"bitcoin","networks":["main", "testnet"]}' https://api.blocknative.com/address
This endpoint will return success if the specified address on the specified network(s) are already being watched for the apikey.
deleteRemove address to watch
DELETE individual addresses from watching for transactions. For each address, specify your API key, the address to remove, the blockchain (currently ethereum and bitcoin are supported), and the networks to remove from watch (see supported networks below).{
"apiKey": "<api-key>",
"address": "<account-address>",
"blockchain": "ethereum",

Blocknative will send pending-simulationnotifications when a watchedAddress is detected in the from or to field of the main transaction or internal transactions of a contract call. The notification will include details of the internal transactions and balance changes resulting from those internal transactions. The internal transaction details and balance changes are probabilistic based on simulating the transaction against the latest confirmed block. Fields are not ordered.
pending-simulation notifications are only available for Ethereum Main Network.
The payload structure for pending-simulation notifications is the same as for confirmed notifications with the addition of the following object.

As a contract call, this transaction has a value for input. The value contains the contract method signature and and parameters to the method call.
If you would like to have your contract decoded (method and parameter names delivered in JSON message) please contact Blocknative at [email protected] or on our Discord server with your contract address (for each supported network) and ABI.
If the watched transaction is a ERC-20/ERC-721 transfer, or an ERC-20/ERC-721 token transfer or transferFromtransaction involves a watched address, the details of the transfer and token involved are included in the transaction notification.
