Borrow. Trade.
Profit. Repay.
One block.

VoltArb scans Uniswap and SushiSwap for price gaps, borrows from Aave with zero collateral, executes the arbitrage, and settles everything in a single atomic transaction. Private relay keeps you invisible.

One transaction. Four steps. Zero collateral.

Every arbitrage opportunity is captured and settled atomically. If any step fails, the entire transaction reverts. You lose nothing but gas.

01
Scan
Node.js engine monitors Uniswap V2/V3 and SushiSwap pools in real time. Calculates net profitability after gas, fees, and slippage.
02
Borrow
When a profitable spread is found, the smart contract triggers an Aave flash loan. Borrow hundreds of thousands in USDC with zero collateral.
03
Execute
Buy low on the cheaper DEX, sell high on the other. Transaction is submitted via Flashbots private relay, invisible to the public mempool.
04
Settle
Repay the flash loan plus 0.09% fee. Pocket the profit. If the trade isn't profitable, the transaction reverts automatically. No risk.
// stack

Built for speed, not demos

Production-grade infrastructure. No wrapper libraries, no abstraction layers you don't control.

Smart Contracts

Solidity on Ethereum

Custom arbitrage contract interacts directly with Aave V3, Uniswap Router, and SushiSwap Router. Optimized for minimal gas.

Off-Chain Engine

Node.js Scanner

Monitors price feeds across multiple pools simultaneously. Calculates profitability thresholds accounting for gas, fees, and slippage.

MEV Protection

Flashbots Relay

Transactions never hit the public mempool. No front-running. No sandwich attacks. Failed transactions don't cost gas.

Lending Protocol

Aave V3 Flash Loans

Borrow millions with zero collateral. 0.09% fee. Atomic repayment within the same transaction or full revert.

// edge

Why VoltArb wins

Private execution

Flashbots relay hides your strategy from competing bots and validators. Your alpha stays yours.

Zero capital risk

Flash loans mean you never put up collateral. If the trade doesn't profit, the transaction reverts. You lose nothing.

Atomic settlement

Borrow, trade, and repay in a single block. No exposure to price movement between steps.

No wasted gas

Flashbots bundles mean you only pay gas on successful transactions. Failed arbs cost you nothing.

Arbitrage at the speed of finality

One block. One transaction. Pure profit extraction from market inefficiency.
