Bankroll

Non Cycle Roll Example

const pinknetwork = require("pinknetworkjs");
const bankroll = new pinknetwork.bankroll()
 
// create the transaction memo for a roll with multiplier 2x and a rake of 5% and a deposit of 10 WAX
let betconfig = bankroll.createBetConfigByMultiplier(2, 5);
// memo returns false if the bankroll is too small to handle this transaction
let memo = bankroll.createRollTransactionMemo(10, "rake.recipient", betconfig)
// subscribe to the roll to get notified when the result is available
if(memo === false) {
    console.log("bankroll too small")
}
 
// TODO: send transaction with memo["memo"]
 
// wait for new roll results
bankroll.getRollSubscription().onNewRollResult((roll) => {
    console.log(roll) // This prints a ROLL_RESULT object. For more information visit the api documentation
})

Cycle Roll Example

const pinknetwork = require("pinknetworkjs");
const bankroll = new pinknetwork.bankroll()
 
// the roll_id of the cycle roll you want to join
const roll_id = 4;
 
// create the transaction memo to join a cycle roll with multiplier 2x and a rake of 5% and a deposit of 10 WAX
let betconfig = bankroll.createBetConfig(2, 1, 4700, 10000);
// memo returns false if the bankroll is too small to handle this transaction
let memo = bankroll.createCycleRollTransactionMemo(roll_id, 10, betconfig)
// subscribe to the roll to get notified when the result is available
if(memo === false) {
    console.log("bankroll too small")
}
 
// TODO: send transaction with memo["memo"]
 
// listen to new roll results
bankroll.getCycleRollSubscription(roll_id).onNewRollResult((roll) => {
    console.log(roll) // This prints a ROLL_RESULT object. For more information visit the api documentation
});
 
// get notified for every new bet for this specific roll_id
bankroll.getCycleRollSubscription(roll_id).onNewBet((bet) => {
    console.log(bet) // A new bet came in. BET_OBJECT
})

Chat Example

const pinknetwork = require("pinknetworkjs");
const chat = new pinknetwork.chat("chatroom");
 
// login method 1 (has to be done once and then cookie authentication will handle everything)
async function login_to_chat_version_1() {
  let sig = await scatter.getArbitrarySignature(user.publicKey, chat.getAuthenticationSignText());
  
  // return authentication token
  return await chat.authenticate_arbitrary(sig, user.account.publicKey, user.account.name, true);
}
 
// login method 2 (has to be done once and then cookie authentication will handle everything and works with hardware wallets)
async function login_to_chat_version_2() {
  let sig = await api.transact(chat.getAuthenticationTransaction(user.account.name, user.account.authority), {broadcast: false, sign: true})
  
  // return authentication token
  return await chat.authenticate_transaction(sig.signatures[0], user.account.publicKey, user.account.name, user.account.authority, true);
}
 
// login method 3 (has to be done on every single connected)
async function login_to_chat_version_3() {
  let sig = await scatter.authenticate(chat.getNonce(), "login", user.publicKey)
  
  await chat.login(sig, user.publicKey, user.account.name, true);
}
 
 
chat.onLoad(function(messages) {
  // on initial connect the past messages are sent
})
 
chat.onMessage(function(message) {
  // new chat message
})
 
chat.onError(function(message) {
  // error occurred with message: message
})
 
chat.onLogin(function(info) {
  // session was successfully created
})
 
chat.onLogout(function() {
  // session was successfully destroyed

class BetConfig

This is a config class which stores multiplier, lower_bound, upper_bound and max_roll and is needed to create transaction memos or calculate the max bet. The rake is also stored indirectly in this class because it is calculated with the difference between multiplier and winning percentage (upper_bound - lower_bound + 1) / max_roll. The methods createBetConfigByMultiplier, createBetConfigByRange, createBetConfig are used to initiate objects of this class.

• GETTER
  • getLowerBound() @return int
  • getUpperBound() @return int
  • getMultiplier() @return float
  • getMaxRoll() @return int

class RollSubscription

This class contains a socket connection to the endpoint /bankroll/v1/rolls/subscribe and fires events whenever the bankroll is updated or a new roll came in which you have subscribed to.

• Methods

  • getMaxBet(BetConfig bet_config)

• Events

  • onNewRollResult(callback cb)
  • onBankrollUpdate(callback cb)

• Subscribers

  • subscribeRakeRecipient(string wax_account)
  • subscribeIdentifier(string identifier)
  • subscribeAll()

class CycleRollSubscription

This class contains the socket connection to the endpoint /bankroll/v1/cycles/subscribe/[:roll_id] and fires a event when a new bet or a new result was published on the blockchain for roll_id

• Methods

  • getMaxBet(BetConfig bet_config)

• Events

  • onNewRollResult(callback cb)
  • onNewBet(callback cb)
  • onRollReduction(callback cb)
  • onBankrollUpdate(callback cb)

Chat

The chat api allows to provide a simple chat with scatter (or any other wallet which can sign) authentication and connects to the pink.network backend servers, so it can be used in frontend only applications.

class ChatAPI

• Methods

  • login(string signature, string publicKey, string account_name) // use scatter method authenticate to sign the nonce
    • signature The signature which is returned by scatter.authenticate(chat.getNonce(), "login", publicKey)
    • publicKey the public Key of the account which you want to authenticate
    • account_name the account name bound to the public key
  • authenticate_arbitrary(string signature, string publicKey, string account_name, bool stay_logged_in) // creates an authentication token which can be used to authenticate to the chat in the future without having to sign anything
    • signature The method scatter.getArbitrarySignature of the text which is returned by getAuthenticationSignText()
    • publicKey the public Key of the account which you want to authenticate
    • account_name the account name bound to the public key
    • stay_logged_in if set to true in browser a cookie will be set which will automatically authenticate the user in the future (you dont need to do anything if this is true)
  • authenticate_transaction(string signature, string publicKey, string account_name, string permission, bool stay_logged_in) // creates an authentication token which can be used to authenticate to the chat in the future without having to sign anything
    • signature The signature of the transaction which is returned by getAuthenticationTransaction()
    • publicKey the public Key of the account which you want to authenticate
    • account_name the account name bound to the public key
    • permission the permission which is used to sign the transaction
    • stay_logged_in if set to true in browser a cookie will be set which will automatically authenticate the user in the future (you dont need to do anything if this is true)
  • logout() // sends logout events and destroys the user's chat session
  • send(string message) // sends a chat message

• Getter

  • isAuthenticated() // is client authenticated?
  • getNonce() // returns the nonce which has to be signed by the user if you use the login method
  • getAuthenticationSignText() // returns the text the user has to sign to use the authenticate_arbitrary method
  • getAuthenticationTransaction() // returns the transaction the user has to sign to use the authenticate_transaction method

• Events

  • onMessage(callback cb) // new message came in
  • onLoad(callback cb) // chat loaded (last 25 messages)
  • onError(callback cb) // error occurred. message is passed as argument
  • onLogout(callback cb) // the socket connection destroyed the user's session
  • onLogin(callback cb) // the authentication was successful. The user info object is passed as callback argument
