Now live on Solana Mainnet

Zero Failed
Transactions

JIT-based Compute Unit optimization engine. Simulate. Optimize. Execute.

Precision Ignition for Every Transaction.

optimize.ts

import { FuesClient } from '@fues/sdk';

// Initialize the optimization engine

const client = new FuesClient(connection);

 

// Optimize and send with guaranteed execution

const result = await client.optimize(tx, {

strategy: 'aggressive',

failSafe: true

});

The Problem

Why Transactions Fail

Every Solana developer and user faces the CU dilemma. There is no winning move without precise computation.

CU Underestimation

Set CU too low and your transaction reverts. Fees wasted. Opportunity lost.

CU Overestimation

Set CU too high and you lose priority fee competition. Slower execution.

DeFi Arbitrage Risk

Complex swaps need precise CU. One wrong estimate means missed profits.

User

Sends TX

CU = ???

Processes

Failed

SOL Wasted

Without precise CU estimation, transactions either fail or get deprioritized

The Solution

How FUES Works

A JIT optimization layer that sits between your wallet and the network. Every transaction is precision-engineered for success.

01

Pre-flight Simulation

Before your transaction reaches validators, FUES simulates it against the latest block state.

02

Dynamic CU Calculation

Calculates exact compute units needed with an intelligent safety margin based on network volatility.

03

JIT Injection

Injects optimal ComputeBudget instructions milliseconds before broadcast.

04

Fail-Safe Guard

If simulation predicts failure, the fuse breaks. Transaction never hits the chain. SOL saved.

Raw Transaction

swap(SOL, USDC, 1.5)

FUES Engine

Simulating... Optimizing...

Optimized Transaction

CU: 187,500 | Fee: 0.00025 SOL

Jito Bundle Integration

Seamlessly integrates with Jito for MEV protection

Failed transactions never hit the chain. The "fuse" breaks before wasting your SOL.

Features

Built for Performance

Every component engineered for speed, reliability, and developer experience.

JIT Optimization

Inject ComputeBudget instructions milliseconds before broadcast. Zero guesswork.

Fail-Safe Mode

Automatically drops transactions if simulation predicts failure. Your SOL stays safe.

Type-Safe SDK

Full TypeScript support with comprehensive type definitions. Seamless dApp integration.

WASM Support

Core logic compiled to WebAssembly. Run simulations directly in the browser.

Priority Fee Estimation

Analyze network contention and Jito bundles. Always optimal fees, never overpay.

Jito Integration

Native support for Jito bundles. MEV protection and guaranteed inclusion.

Integration

Get Started in Minutes

Drop-in SDK for your existing Solana projects. No complex setup required.

import { FuesClient } from '@fues/sdk';
import { Connection, Keypair } from '@solana/web3.js';

// Initialize connection and client
const connection = new Connection('https://api.mainnet-beta.solana.com');
const client = new FuesClient(connection);

// Your existing transaction
const transaction = await buildSwapTransaction({
  fromToken: 'SOL',
  toToken: 'USDC',
  amount: 1.5
});

// Optimize with FUES - that's it!
const optimized = await client.optimize(transaction, {
  strategy: 'aggressive',
  priorityFeeMultiplier: 1.2,
  failSafe: true
});

// Send with confidence
const signature = await client.send(optimized);
console.log('Transaction confirmed:', signature);
