Docs

When creating a new account, there are 4 required parameters and 1 optional parameter.

new  Accounts(crypto_address, crypto_secret, coin, api_provider, api_key-optional);

crypto_address

This is your crypto address. For example, a bitcoin address looks like 1KHwtS5mn7NMUm7Ls7Y1XwxLqMriLdaGbX

crypto_secret

This is your crypto secret. You need this to prove to the network that you are the owner of the coin, which then enables you to send crypto to other wallets.

coin

Supported assets - use the lowercase ticker in the "coin" parameter

Coin	Ticker
BITCOIN	btc
ETHEREUM	eth
LITECOIN	ltc

Sending transactions

When sending transactions, there are normally 2 parameters, with an optional third for ETH

account.send(reciever, amountToSend, *gas*)

reciever

The reciever address you would like to send the crypto to.

amountToSend

This is the amount of crypto you would like to send

If you would like to send all of the crypto in your wallet (Sweeping) pass "all" as a string instead of a number in this parameter

gas

The max gas you would like to be consumed in ETH transactions. The default is 2100 gwei, but you can increase/decrease this number as you please.

Examples

BTC, LTC

Send BTC (Bitcoin)

const  Accounts  =  require("@joshyzou/sendcrypto");

  

// Send BTC

  

const  account  =  new  Accounts("BTC Address", "BTC Secret", "btc", "sochain");

await account.send("reciever address", 0.01);

  

Send LTC (Litecoin)

const  Accounts  =  require("@joshyzou/sendcrypto");

  

// Send LTC

  

const  account  =  new  Accounts("LTC Address", "LTC Secret", "ltc", "sochain");

await account.send("reciever address", 0.01);

You can replace "BTC" with "ZEC" or "BCH" in the following examples:

Send entire balance (sweep)

const  Accounts  =  require("@joshyzou/sendcrypto");
