Running Bots & Scripts

Vault operations require automation for optimal performance. This page covers why automation is needed, available scripts, and infrastructure recommendations.

Important: You must host your own automation. Ranger does not provide managed bot services. You are responsible for deploying, running, and monitoring your own scripts and bots.

Why Automation Is Needed

Task	Why It Needs Automation
Rebalancing	Yield rates change frequently; manual rebalancing misses optimal allocations
Reward claiming	Protocol rewards accrue continuously; manual claiming leaves value uncollected
Reward swapping	Claimed reward tokens need to be swapped to base asset to compound
Position monitoring	Raydium CLMM positions go out-of-range; Drift positions need risk monitoring
Fee harvesting	Accumulated fees should be harvested periodically

Script Repositories

The Ranger team provides reference scripts for common operations:

Repository	Use Case
voltrxyz/lend-scripts	Lending strategy init (Project0, Save)
voltrxyz/kamino-scripts	Kamino strategy init, rewards claiming
voltrxyz/drift-scripts	Drift vaults/lend/perps strategy init, position management
voltrxyz/spot-scripts	Jupiter Swap/Lend strategy init
voltrxyz/client-raydium-clmm-scripts	Raydium CLMM strategy init
voltrxyz/trustful-scripts	Trustful adaptor strategy init
voltrxyz/rebalance-bot-template	Production-ready rebalance bot (equal-weight allocation)

Rebalance Bot Template

The rebalance-bot-template is a production-ready bot that handles the core automation tasks listed above. It distributes funds equally across lending strategies on a fixed schedule and includes:

• Rebalance loop — equal-weight allocation across all strategies, triggered on interval and on new deposits

• Refresh loop — keeps on-chain receipt values up to date

• Harvest fee loop — collects protocol/admin/manager fees

• Claim reward loops — claims Kamino farm rewards and swaps them back via Jupiter

Supports Drift, Jupiter Lend, Kamino Market, and Kamino Vault strategies out of the box.

git clone https://github.com/voltrxyz/rebalance-bot-template.git
cd rebalance-bot-template
pnpm install
cp .env.example .env   # fill in your vault addresses and keypair
pnpm run build && pnpm start

See the repository README for full configuration options and Replit deployment instructions.

Script Structure Example

A basic rebalancing script:

import { VoltrClient } from "@voltr/vault-sdk";
import { Connection, Keypair } from "@solana/web3.js";

async function main() {
  const connection = new Connection(process.env.RPC_URL!);
  const client = new VoltrClient(connection);

  const managerKp = Keypair.fromSecretKey(
    Uint8Array.from(JSON.parse(process.env.MANAGER_KEY!))
  );

  // 1. Check current allocations
  const vaultData = await client.getVault(vaultPubkey);
  const idleBalance = vaultData.asset.totalValue; // simplified

  // 2. Check strategy yields (via API or protocol SDKs)
  // 3. Determine optimal allocation
  // 4. Execute rebalance transactions

  console.log("Rebalance complete");
}

main().catch(console.error);

Key Considerations

• Gas budget: Ensure your manager wallet has enough SOL for all automated transactions. Monitor and top up regularly.

• Error handling: Scripts should handle transaction failures gracefully (retry logic, alerting).

• Rate limiting: Respect RPC provider rate limits. Use exponential backoff on failures.

• Idempotency: Design scripts to be safely re-runnable in case of partial failures.
