Frequently Asked Questions

FlashLoanLab is a DeFi arbitrage platform that continuously scans decentralised exchanges across Base, Arbitrum, and Ethereum for price discrepancies, simulates them on a mainnet fork to verify profitability, and optionally executes them using Aave V3 flash loans — all from a single dashboard.

A flash loan is a DeFi primitive that lets you borrow any amount of capital with zero collateral, use it within a single transaction, and repay it (plus a small fee) before that transaction ends. If repayment fails, the entire transaction reverts — meaning you can never owe money you don't have. FlashLoanLab uses Aave V3 flash loans to fund arbitrage trades.

Arbitrage is the practice of buying an asset cheaply on one exchange and simultaneously selling it at a higher price on another, pocketing the difference. On-chain arbitrage is fully automated: a smart contract executes both legs atomically so the opportunity can't be front-run mid-trade.

No. Flash loans provide the capital. You only need enough ETH in your wallet to cover gas fees. Your capital is never locked in a contract.

FlashLoanLab charges no subscription fee. Instead, we take a percentage of the gross profit on winning trades only. Losing trades (where the flash loan would revert) cost you only gas. The split is enforced on-chain by the FlashLoanReceiver contract — the platform fee is transferred to the treasury address automatically before the remaining profit reaches your wallet.

Free plan: platform takes 25%, you keep 75%. Pro: 20%/80%. Elite: 15%/85%. Enterprise: custom, as low as 10%. The platform fee percentage is hard-capped at 30% in the smart contract and cannot be changed by the platform after you initiate a transaction.

If the trade can't repay the flash loan after fees, the entire transaction reverts on-chain. No profit is generated and no platform fee is charged. You only pay the gas cost for the failed transaction, typically a few dollars or less.

No. The fee rate is encoded into the transaction at execution time and enforced by the smart contract. Even if the platform were compromised, the on-chain split cannot be altered once the transaction is submitted.

Flash loans are self-collateralising — if a trade is unprofitable, it reverts and nothing is lost except gas. However, DeFi always carries smart contract risk, price oracle manipulation risk, and gas cost risk. Start with Simulator mode (paper trading) to understand how the system works before executing live trades.

Simulator mode runs opportunities against a Hardhat fork of the mainnet — real state, real prices, but no real transactions. You can see exactly how a trade would perform, including gas estimates, profit splits, and potential failure reasons, without spending a cent.

The contract has been reviewed internally for common vulnerabilities — including reentrancy, unauthorized callback access, and fee cap enforcement — but has not yet undergone a formal third-party audit. Use the platform with amounts you can afford to lose and check the contract source on the respective chain explorer before executing live.

Safety Controls let you set hard limits on the auto trading system: minimum score threshold, minimum net profit per trade, maximum daily loss, maximum number of trades per day, and maximum failed transactions. Breaching any limit automatically pauses the bot. An Emergency Stop instantly halts all activity.

We never ask for your private key for manual execution — you sign transactions directly in MetaMask, Coinbase Wallet, or any wagmi-compatible wallet. For Auto Trading, an optional trading wallet key can be stored, but it is encrypted with AES-256-GCM using a server-side key before hitting the database and is never logged or exposed to the frontend.

Live execution is supported on Base (Chain ID 8453), Arbitrum One (42161), and Ethereum mainnet (1). The Solana adapter is in simulator-only mode — it detects spread opportunities via Jupiter V6 quotes but does not execute transactions.

Uniswap V2 and V3 pools on all supported EVM chains. Solana scanning uses Jupiter V6 aggregated quotes, which covers most major Solana DEXes including Orca, Raydium, and Meteora.

Scores run from 0–100 and factor in: estimated net profit after gas and fees, simulation result (passed/failed), token safety (GoPlus API), chain congestion, liquidity depth, and spread confidence. Auto Trading only fires on opportunities scoring ≥90.

Arbitrage opportunities are extremely time-sensitive. If your transaction is not mined quickly, price conditions change and the trade may revert when it does execute. FlashLoanLab provides gas estimates in the pre-flight confirmation screen — always execute with an adequate gas price.

Plan upgrades are managed through the settings panel in your dashboard. Because we charge revenue share rather than subscriptions, there are no recurring payment cards to enter — plan tier directly determines your fee percentage.

Yes — the scanner, simulator, and most dashboard features work without a wallet. You only need to connect a wallet for Manual Live execution. Auto Trading uses a separately registered trading wallet stored (encrypted) server-side.

The Free plan is free forever. You can scan opportunities and run unlimited simulations with no time limit. Live execution (Manual and Auto Trading) requires Pro or above.
