Nemo Vaults SDK

A TypeScript SDK for interacting with Nemo Vaults on the Sui blockchain. This SDK provides comprehensive functionality for managing liquidity vaults, including deposits, withdrawals, rebalancing, and administrative operations.

Features

• Vault Management: Create, configure, and manage different types of vaults (Stable, Uncorrelated, Drift)
• Liquidity Operations: Deposit and withdraw liquidity with automatic optimization
• Automated Bots: Built-in reward collection and rebalancing bots
• Administrative Functions: Complete admin interface for vault configuration
• Multi-Protocol Support: Integration with various staking protocols (Haedal, Volo, Aftermath)
• Docker Support: Ready-to-use Docker containers for production deployment

Installation

npm install @nemoprotocol/vaults-sdk
# or
yarn add @nemoprotocol/vaults-sdk
# or
pnpm add @nemoprotocol/vaults-sdk

Quick Start

import { Vaults, Admin } from '@nemoprotocol/vaults-sdk';
import { SuiClient } from '@mysten/sui/client';

// Initialize the SDK
const suiClient = new SuiClient({ url: 'https://sui-mainnet.blockvision.org' });
const vaults = Vaults.createSDK({
  client: suiClient
});

// Get all vaults
const vaultList = await vaults.getVaultList();

// Get a specific vault
const vault = await vaults.getVault('vault-id');

// Get user's vault balances
const balances = await vaults.getOwnerVaultsBalance('user-address');

Core Concepts

Vault Types

1. Stable Vaults: Optimized for stable asset pairs with minimal price volatility
2. Uncorrelated Vaults: Designed for assets with low correlation, includes rebalancing triggers
3. Drift Vaults: Specialized for trending markets with directional price movements

Liquidity Management

• Both-sided deposits: Provide both tokens in optimal ratio
• One-sided deposits: Provide single token with automatic swapping
• Flexible withdrawals: Withdraw as LP tokens or individual assets
• Slippage protection: Configurable slippage tolerance for all operations

Examples

Basic Vault Operations

import { Vaults, Admin, InputType } from '@nemoprotocol/vaults-sdk';
import { SuiClient } from '@mysten/sui/client';
import { Transaction } from '@mysten/sui/transactions';

// Initialize the SDK
const suiClient = new SuiClient({ url: 'https://sui-mainnet.blockvision.org' });
const vaults = Vaults.createSDK({
  client: suiClient
});

async function basicVaultOperations() {
  try {
    // 1. Get all available vaults
    console.log('Fetching all vaults...');
    const allVaults = await vaults.getVaultList();
    console.log(`Found ${allVaults.length} vaults`);

    // 2. Get detailed information about a specific vault
    const vaultId = allVaults[0].id;
    const vault = await vaults.getVault(vaultId);
    if (!vault) {
      console.error('Vault not found');
      return;
    }
    console.log('Vault details:', {
      id: vault.id,
      coinTypeA: vault.coin_type_a,
      coinTypeB: vault.coin_type_b,
      totalSupply: vault.total_supply,
      depositEnabled: vault.is_deposit_enabled
    });

    // 3. Check user's vault balances
    const userAddress = 'user-wallet-address';
    const userBalances = await vaults.getOwnerVaultsBalance(userAddress);
    console.log(`User has positions in ${userBalances.length} vaults`);

    // 4. Calculate deposit amount for one-sided deposit
    console.log('Calculating deposit amount...');
    const depositCalc = await vaults.calculateDepositAmount({
      vault_id: vaultId,
      is_amount_a: true,
      input_amount: '1000000', // 1 token (assuming 6 decimals)

      amountB: depositCalc.amount_b,
      lpTokens: depositCalc.ft_amount,
      swapRequired: !!depositCalc.swap_result
    });

    // 5. Execute deposit transaction
    const tx = new Transaction();
    const lpToken = await vaults.deposit({
      vault_id: vaultId,
      slippage: 0.01,
      deposit_result: depositCalc,

Automated Bots

The SDK includes two automated bots for production use:

Reward Bot

Automatically collects and compounds vault rewards.

# Run directly
pnpm run run:reward

# Or with Docker
docker-compose up reward-bot

Rebalance Bot

Monitors and rebalances uncorrelated vaults when price thresholds are reached.

# Run directly  
pnpm run run:rebalance

# Or with Docker
docker-compose up rebalance-bot

Environment Configuration

Create a .env file with the following variables:

# Sui Network
SUI_PRIVATE_KEY=your-base64-encoded-private-key
FULL_NODE_URL=https://sui-mainnet.blockvision.org

# Slack Notifications (for bots)
SLACK_TOKEN=xoxb-your-slack-bot-token
SLACK_CONVERSATION_ID=your-channel-id
SLACK_VAULT_REBALANCE_CONVERSATION_ID=rebalance-channel-id

# Optional
NODE_ENV=production

Docker Deployment

The SDK provides ready-to-use Docker containers:

# Build and run both bots
docker-compose up -d

# Run specific bot
docker-compose up -d reward-bot
docker-compose up -d rebalance-bot

# View logs
docker-compose logs -f reward-bot

See DOCKER.md for detailed Docker setup instructions.

Error Handling

The SDK uses a comprehensive error handling system:

import { VaultsErrorCode } from '@nemoprotocol/vaults-sdk';

try {
  const vault = await vaults.getVault('invalid-id');
} catch (error) {
  if (error.code === VaultsErrorCode.ObjectNotFound) {
    console.log('Vault not found');
  }
}
