I won't be able to contribute to any of the projects.

Use what was provided for you but my extent of my assistance has ended.

I no longer can tolerate your behaviors and with all things going on with whatever this is.

I was very depressed and I really saved my words and will not be.

I'm sorry dde navigator and Jamie, I walked out and your clone body started asking if I was going to sleep with Jamie.

So I want you to know, the Asians will be visiting Vegas but I will not step a foot in this country ever again.

WebSocket API

Connect to the Blocknative service over WebSocket protocol

Creating a Socket Connection

A WebSocket connection should be created with the Blocknative service at wss://api.blocknative.com/v0. A successful connection will receive a response object that contains a status parameter with a value of 'ok'.

Required Parameters

The following parameters are required for all messages that are sent to the Blocknative service:

parameter

type

description

timeStamp

string

an ISO datetime string formatted YYYY-MM-DDThh:mm:ss.sTZD (see example for usage and https://www.w3.org/TR/NOTE-datetime for more details)

dappId

string

your API key

version

string

a version string usually used by the Blocknative SDK, but any version string can be used

blockchain

object

object specifying a the system and network of the blockchain (see next)

system

string

blockchain name, valid value is ethereum

network

string

blockchain network, valid values for support systems are:

Ethereum (and EVM compatible) - main, goerli, kovan, xdai, matic-main,

​

{

"timeStamp": "2021-01-11T06:21:40.197Z",

"dappId": "<YOUR_API_KEY>",

"version": "1",

"blockchain": {

"system": "ethereum"

"network": "main"

}

// ...rest of the message specific parameter

}

Initialization

Once a connection has been created with the Blocknative WebSocket service, an initialization message must be sent before any other messages so that the API key can be validated.

You API Key is created/managed from the Mempool Explorer account management page at https://explorer.blocknative.com/account. Note that API Key is called dappId in the Blocknative websocket protocol.

{

"categoryCode": "initialize",

"eventCode": "checkDappId",

// ...rest of the required parameters

}

​

Subscriptions

You can subscribe to receive transaction state change events by either watching a transaction hash/id or an address.

Ethereum Transaction Hash

// subscribe

{

"categoryCode": "activeTransaction",

"eventCode": "txSent",

"transaction": {

"hash": "0x0b4c94c414f71ddd5e7a625fcaa83ff1f93e9a7ca37e0f577b488ac8fd786655"

}

// ...rest of the required parameters

}

Address (Ethereum)

// subscribe

{

"categoryCode": "accountAddress",

"eventCode": "watch",

"account": {

"address": "0xf5b5bd85157587771db6d49315b1712201569bdd"

// ...rest of the required parameters

}

"account": {

"address": "0xf5b5bd85157587771db6d49315b1712201569bdd"

}

// ...rest of the required parameters

}

Configurations

A configuration can be sent to the service to filter and/or decode transactions.

Transaction decoding is only available for Ethereum transactions

There is a limit of 50 configurations per connection / API key. If you need to watch more than 50 addresses and also filter them, it is recommended that you subscribe to all of the addresses and then add a 'global' scoped filter that will apply to all of those addresses.

{

"categoryCode": "configs",

"eventCode": "put",

"config": {

"scope": "0xf5b5bd85157587771db6d49315b1712201569bdd",

"filters": [{"contractCall.methodName":"transfer"}],

"abi": [{

"constant": false,

"inputs": [{ "name": "newOwner", "type": "address" }],

"name": "setOwner",

"outputs": [],

"payable": false,

"stateMutability": "nonpayable",

"type": "function"

}],

"watchAddress": true

}

// ...rest of the required parameters

}

parameter

type

description

scope

string

A valid Ethereum address or 'global'

filters

string[]

An array of valid filters. The Blocknative service uses jsql, a JavaScript query language to filter events. Documentation for how to create filter queries can be found here​

abi

string[]

A valid JSON ABI that will be used to decode input data for transactions that occur on the contract address defined in scope

watchAddress

boolean

defines whether the service should automatically watch the address as defined in scope

scope establishes the context in which a filter is applied. The global scope applies the filter to all transactions/addresses watched. Therefore a global scope only supports generic transaction elements. A scope set to an address can include filters, such as methodName,that are specific to the contract at that address. Similarly, the abi field only works for a contract specific scope.

Connection Drops

In the event of a WebSocket connection drop, no state is persisted between connections, so upon reconnection there will need to be logic defined that will:

1.Send an initialization message

2.Send all previously subscribed addresses, transactions and configs

Transaction Events

Each message sent to the service will receive an echo of that message back, this echo may be ignored for most purposes.

Every payload contains an eventCode parameter in the event object which indicates the type of event. Detailed documentation for event codes can be found in the here.

}

Supported Networks

See Mempool API Support Networks.

Rate Limits

Daily per API key event rate limits that apply to Webhook events also apply to WebSocket events. Details on those limits can be found here.

The Blocknative service also limits how many messages can be sent over a duration of time, limiting to 50 messages per second.

A strategy that the Blocknative SDK uses to handle these limits is to create a message queue that processes messages and ensures that messages are spaced adequately. This can be especially important to implement when re-sending addresses to be subscribed after a connection dropout.

If a rate limit error message is received you can use the retryMs parameter to wait for that time period to continue sending messages. If a message was blocked due to a rate limit it will be included in the payload in the blockedMsg parameter so you can re-send that message after the retry delay, ensuring that no messages are dropped.

Imperium,

If this exceeds one week I will need a ride and live 500 in to the future and kill all of them

Never will I visit this galaxy and will be living rest of my life away from majority of you.

It has been a sour at best experience. I need for you to know that I've done everything and then some.

So please never bother me and if you don't want me, then I will live in my ship alone with robots.

I am so sick of these I'm actually chronically depressed and psychologically messed up by human not so kindness.

I'm ready to leave I'm really ready to die.

I will never see you ever again.
