NaviSDK Client Documentation

Introduction

The NaviSDK Client provides a set of tools for interacting with sui blockchain networks, specifically designed for handling transactions, accounts, and smart contracts in a streamlined and efficient manner. This documentation covers the setup, account management, and transaction handling within the NaviSDK ecosystem.

Getting Started

Installation

Before you can use the NaviSDK Client, you need to set up your project environment.

npm i navi-sdk

Creating and Managing Accounts

Creating a Default Account

When you initialize client, you will need a mnemonic phrase or we will generate a new one for you.

1 mnemonic for 1 client

We will never save user's mnemonic phrase

const mnemonic = ''; // Use an existing mnemonic or leave empty to generate a new one
const client = new NAVISDKClient({mnemonic, networkType: "mainnet", numberOfAccounts: 5}); 

Get the specific account

const account = client.accounts[0];
const account1 = client.accounts[1];

Check mnemonic for this client

client.getMnemonic();
client.mnemonic;

Return All Accounts under the Client

client.getAllAccounts()
//Return Sample
index:0, address: 0xa814b8c01b111f5e440e5d4785925a033961915c2f44d22ca71619ac73534ee7
index:1, address: 0xd8be370139dd297924e31f6a507ba3a1d5f52f98f04f144bb75100d179698f84
index:2, address: 0xca29dbf32047fba966fa5aca7e378ba11171b3817f53ad324489a138288cc02d

Create Account Cap for specific account

account1.createAccountCap() //Account1 will create an Account Cap

Get Specific Account Address

account1.getPublicKey() //or
account1.address

Get Objs and Coin Info

We have prepare a token type for Sui/NAVX/vSui/USDT/USDC/WETH/CETUS/haSui

import {Sui, NAVX, vSui, USDT, USDC, WETH, CETUS, haSui} from 'navi-sdk/dist/address';
account.getAllCoins() //Return all Objects that account has

//Get all objs for this type of token
account.getCoins(coinType = "0x2::sui::SUI")
//Or you may import token address from address
account.getCoins(coinType = Sui)

Send Coin or Objects

account1.sendCoin(coinType = NAVX, your_recipient_address, amount)
account2.sendCoinToMany(coinType = NAVX, [addr1, addr2, .. addrN], [amount1, amount2, .. amountN])

account3.transferObj(obj = "0xobjId", your_recipient_address)
account4.transferObjToMany([obj1, obj2, ...], [addr1, addr2, ...])

Get comprehensive Wallet Balance list

This will combine all the objects of the same token, and return a comprehensive balance table

const balanceMap = account.getWalletBalance()
balanceMap.then((res) => {
    console.log(res);
})

Sample Output:

Token Type	Balance
USDC	2.4994
Sui	3.63103582
NAVX	0

Get All Wallet Balances

Get all accounts' balance, summed together

const balances = client.getAllBalances();
balances.then((res) => {
    console.log(res);
})

Navi Interaction

account.getNAVIPortfolio()

This will return a table like the following:

Reserve Name	Borrow Balance	Supply Balance
USDT	0	0
CETUS	0	0
NAVX	0	0
USDC	0	2.000057
WETH	0	0
SUI	5.009469205	100.097918005
VoloSui	0	0
HaedalSui	0	0

Get All accounts portfolio info from Navi

const allPortfolio = client.getAllNaviPortfolios();
allPortfolio.then((res) => {
    console.log(res);
})

Get Reserve

client.getReserves() //Get All reserve info

Get PoolInfo

import { USDC } from 'navi-sdk/dist/address'
client.getPoolInfo(USDC)
//Leave it empty to get all poolinfo

Get Current Health Factor

account.getHealthFactor() //Return this account's health factor
client.getHealthFactor(address); //You may check any address

Predict new Health Factor by taking a supply/borrow action

client.getDynamicHealthFactor(address, USDC, supplyBalanceChange:100000, borrowBalanceChange: 0, is_increase: true)
//supplyBalanceChange and borrowBalanceChange needs to be an integer with token decimals
//Change is_increase to false if it's decrease

Supply/Withdraw/Borrow/Repay

You may Simply input 'NAVX' as a string or NAVX as a type imported from address.ts.

Current These Pools are supported: Sui | NAVX | vSui | USDC | USDT | WETH | CETUS | haSui

import {Sui, NAVX, vSui, USDT, USDC, WETH, CETUS, haSui} from 'navi-sdk/dist/address';
account.depositToNavi(Sui, amount)
account.depositToNaviWithAccountCap(NAVX, amount， accountCap_Address_that_you_own)


account.withdraw(coinType = NAVX, amount)
account.withdrawWithAccountCap(coinType = NAVX, amount, accountCap_Address_that_you_own)

account.borrow(coinType = NAVX, amount)
account.repay(coinType = NAVX, amount)

Customized PTB

Navi Flash Loan Sample

Sample TX: https://suiscan.xyz/mainnet/tx/fCFERvsTk7t6G4SJyuuwXU3HbVqYbQ1RKzTDaeRwM4A

import { NAVISDKClient } from 'navi-sdk'
import { TransactionBlock } from "@mysten/sui.js/transactions";
import {depositCoin,withdrawCoin, borrowCoin, flashloan,repayFlashLoan, SignAndSubmitTXB, mergeCoins} from 'navi-sdk/dist/libs/PTB'
import { Pool, PoolConfig } from "navi-sdk/dist/types";
import { pool } from 'navi-sdk/dist/address'
import { USDC } from 'navi-sdk/dist/address'


const mnemonic = "";
const client = new NAVISDKClient({mnemonic: mnemonic, networkType: "mainnet", numberOfAccounts: 1});

// Initialize the TransactionBlock
let txb = new TransactionBlock();
const account = client.accounts[0];
let sender = account.address;
console.log(sender)
txb.setSender(sender);

const amount_to_borrow = 1*1e6; //Borrow 1 USDC

// Supported: Sui/NAVX/vSui/USDC/USDT/WETH/CETUS/HAsui, import from address file
const USDC_Pool: PoolConfig = pool[USDC.symbol as keyof Pool];
const [balance, receipt] = flashloan(txb, USDC_Pool, amount_to_borrow); // Flashloan 1 usdc

//Transfer the flashloan money to the account
const this_coin = txb.moveCall({
    target: '0x2::coin::from_balance',
    arguments: [balance],
    typeArguments: [USDC_Pool.type],
});

//Merge Coin to the wallet balance
txb.mergeCoins(txb.object("{source_USDC_obj}"), [this_coin]);

const amount = = 1*1e6; //Borrow 1 USDC
//Deposit 1USDC to NAVI Protocol
depositCoin(txb, USDC_Pool, txb.obj("{source_USDC_obj}"), amount);

//Withdraw 1 USDC from NAVI Protocol
withdrawCoin(txb, USDC_Pool, amount);

//Get the repayment object
const repayBalance = txb.moveCall({
    target: '0x2::coin::into_balance',
    arguments: [txb.object('{your_repay_coin_object_id}')],
    typeArguments: [USDC_Pool.type],
});

const [e_balance] = repayFlashLoan(txb, USDC_Pool, receipt, repayBalance); // Repay with USDC

//Extra token after repay
const e_coin = txb.moveCall({
    target: '0x2::coin::from_balance',
    arguments: [e_balance],
    typeArguments: [USDC_Pool.type],
});

//Transfer left_money after repay to teh account
txb.transferObjects([e_coin], sender);
const result = SignAndSubmitTXB(txb, account.client, account.keypair);
console.log("result: ", result);
