DEXs & liquidity pools
Order matching and depth held in on-chain pools rather than a central book.
Automated DeFi arbitrage
Price gaps close in milliseconds.
Price gaps close in milliseconds.
So does FlashDex.
An automated engine that scans decentralised markets, borrows liquidity through flash loans, and settles arbitrage inside a single atomic transaction — across seven chains, with no capital locked up mid-trade.
- Chains covered
- 7
- Liquidity sources

01The product
The markets, live.
Every arbitrage decision starts with the same raw material: price, bid, ask and the gap between them. These are live spot quotes for the assets the engine watches, refreshed every few seconds.

How an execution runs
Schematic · not a live trade
Step 01 · Borrow
Draw principal from the pool. No collateral posted.
Step 02 · Execute
Buy the low leg, sell the high leg, same block.
Step 03 · Repay
Principal plus protocol fee returns to the pool.
Step 04 · Settle
Residual is booked. Any failure reverts the whole call.

02The shift
Markets moved on. The plumbing changed.
Traditional finance routes every trade through intermediaries that keep business hours. Decentralised finance replaced them with smart contracts that settle continuously and publicly. FlashDex automates advanced trading strategies inside that second system.
Traditional finance
- Banks & intermediaries
- Business hours only
- Centralised control
- Slow settlement
- Limited transparency
Decentralised finance
- Smart contracts
- 24/7 global markets
- Automated execution
- Instant settlement
- Transparent blockchain
Lending protocols
Over-collateralised markets that also expose uncollateralised flash liquidity.
Stablecoins & yield farms
The settlement units and incentive layers the strategies price against.
Flash loans & bridges
Atomic borrowing, and the interoperability rails that make cross-chain possible.
03Flash loans
Borrow a million dollars for one block.
A flash loan lets a smart contract draw liquidity from a decentralised protocol with no collateral — on the condition that borrowing, execution and full repayment all complete inside a single transaction. If any step fails, the whole transaction reverts and no state change is written on-chain.
Primary uses — arbitrage, refinancing, collateral swaps, liquidations, liquidity optimisation
Step 01
Borrow
Liquidity is drawn from a lending pool with no collateral posted.
Step 02
Execute
The strategy runs — buy, route, swap, sell — in the same transaction.
Step 03
Repay
Principal plus protocol fee returns to the pool before the block closes.
Step 04
Complete
Whatever remains after repayment is the captured differential.
04Liquidity sources
Where the liquidity comes from.
FlashDex holds no float of its own. Every position is opened with liquidity drawn from established DeFi protocols for the length of one transaction, then returned in the same block.
Per-transaction flow
- Drawn from pooled liquidity
- $1,000,000
- Returned to the pool
- −$1,000,000
- Protocol fee
- Paid in-block

Custody of user fundsNone
Aave
Flash-loan originatorThe primary source of uncollateralised flash liquidity. Funds are released and repaid inside the same transaction, or the call reverts.
Balancer
Vault liquidityWeighted and stable pools accessed through vault-level accounting, giving multi-asset flash liquidity in one call.
Uniswap pools
Execution venueDeep on-chain spot depth across Ethereum and its L2s. Carries the buy and sell legs where routing favours it.
PancakeSwap pools
Execution venueBNB Chain depth. Extends coverage and routing options beyond the Ethereum ecosystem.
Additional DeFi sources
ExtensibleFurther pooled venues are integrated as their depth, fee structure and reliability qualify them. The engine routes to whichever source prices the position best at the moment of execution.
05Arbitrage
The same asset, two prices.
Arbitrage captures the difference in price for one digital asset across multiple markets — executing both sides before the prices converge and the window closes.

$1.24
Gap
$0.08
Exchange B
Sell price
$1.32
Why price gaps exist
- 01Varying liquidity depths
- 02Independent trading volume
- 03User demand imbalances
- 04Network congestion
- 05Isolated liquidity pools
Four strategies
Cross-DEX
Buy and sell the same asset across two DEXs on the same blockchain.
Cross-chain
Capture gaps across Ethereum, BNB Chain, Polygon and other networks via bridges.
Triangular
Route trades through three assets on one exchange to exploit internal pricing.
Statistical
Models detect temporary anomalies before mean reversion closes the spread.
06Cross-chain
Seven networks, one price surface.
Price differences across Ethereum, BNB Chain, Polygon, Avalanche, Arbitrum, Base and Optimism create systematic capture opportunities.
EthereumBNB ChainPolygon
AvalancheArbitrumBaseOptimism
- 01Monitor asset prices across chains
- 02Evaluate bridge availability and costs
- 03Execute synchronised buy / sell strategies
- 04Optimise timing for maximum capture
Cross-chain arbitrage executes over interoperability infrastructure, with additional settlement considerations compared with same-chain arbitrage.
07The engine
Seven stages, no hands on the wheel.
Every stage executes autonomously. There is no manual intervention between detection and settlement — the window is too short for one.
01Observe
Market scanner
Continuous price observation across connected DEXs and chains.
02Evaluate
Opportunity detection
Candidate spreads are isolated and measured against cost of execution.
03Borrow
Flash loan access
Liquidity is drawn from Aave, Balancer or pooled DEX sources for the transaction.
04Execute
DEX execution
Both legs of the trade are routed and submitted inside the same block.
05Repay
Settlement
Principal and protocol fee are returned; the transaction is finalised or reverted.
06Account
Profit calculation
The residual after repayment, gas and slippage is accounted to the position.
07Close
Transaction complete
State is written on-chain and the scanner returns to observation.
08Worked example
Arbitrage in action
ETH quoted at $3,000 on Exchange A and $3,030 on Exchange B. $1,000,000 of liquidity is accessed via flash loan, then bought, transferred, sold and repaid inside one transaction.
$1,000,000Buy position
−$1,000,000Transfer
$1,030,000Sell proceeds
−$1,000,000Loan repayment
