Zero Failed
Transactions
JIT-based Compute Unit optimization engine. Simulate. Optimize. Execute.
Precision Ignition for Every Transaction.
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 = ???
Validator
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.
Pre-flight Simulation
Before your transaction reaches validators, FUES simulates it against the latest block state.
Dynamic CU Calculation
Calculates exact compute units needed with an intelligent safety margin based on network volatility.
JIT Injection
Injects optimal ComputeBudget instructions milliseconds before broadcast.
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.

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
