What is Quantum Arb?
Quantum Arb — is a public on-chain arbitrage system on the Solana blockchain. All calculations and simulations are performed directly in the on-chain program, not on the client side. Transactions are executed only when there is real profit, and incorrect ones are rejected. Quantum Arb is free to use and takes 15% fee on profits.
What is Arbitrage?Trading Strategies
Quantum Arb supports two arbitrage strategies — Backrun and Transaction Spam.
Backrun is a reactive arbitrage strategy, which allows executing transactions immediately after a price imbalance occurs between pools. Unlike Transaction Spam, where transactions are sent continuously, Backrun waits for a signal from the blockchain and uses pre-signed transactions.
Transaction Spam Strategy — is a high-frequency arbitrage strategy, in which the bot continuously sends pre-prepared transactions through different processors to achieve maximum reaction speed and coverage of arbitrage opportunities. Unlike reactive strategies, Spam Strategy does not wait for signals from the network — it constantly sends transactions, ensuring constant presence with leaders.
Backrun covers the market more broadly, while Spam provides maximum reaction speed.
Supported DEXs
Quantum Arb allows sending multiple pools for a single token within one transaction. The program automatically calculates the most profitable route among the provided pools.
Supported DEX protocols:
Meteora DLMM
Meteora DAMM v1 (soon)
Meteora DAMM v2
Raydium CLMM
Raydium AMM
Raydium CPMM
PumpSwap
Orca Whirlpools (soon)
Transaction Processors
Quantum Arb uses a network of processors (JITO, NOZOMI, SENDER, NEXT_BLOCK ...) to send transactions directly to Solana validators. These services provide minimal delivery latency.
Each strategy interacts with processors differently:
Backrun — simultaneously sends the same prebuilt transaction with a single Durable Nonce to all active transaction processors, which maximizes the chance of closing the arbitrage window first.
Transaction Spam — allows independently configuring the transaction send frequency (TPS) for each transaction processor separately. Thus, you can spam transactions from different processors in parallel, even without your own expensive infrastructure, while remaining competitive.
Supported transaction processors:
Jito
ZeroSlot
Nozomi
NextBlock
BlockRazor
Astraline
Sender (Helius)
Fast
Each processor can be flexibly configured through the configuration: enable/disable, TPS limits, proxies, TIP values and API keys.
Full Automation — 24/7 running
Quantum Arb allows full automation of the arbitrage system. The user does not need to manually search for tokens, select pools or create Table Lookup tables — all of this is done automatically using Pools Loader and Table Lookup Manager.
Pools Loader — is a module that is responsible for automatic loading of pools into the system according to user-specified filters. The system automatically finds and maintains up-to-date pools that match these filters, completely removing manual work from the user.
Table Lookup Manager — is the module responsible for automatic management of Address Lookup Tables (ALT) of the user. It works in conjunction with Pools Loader and provides full automation when adding new pools to the system.
Thanks to these modules, the system can operate 24/7, fully managing pool selection, account preparation and arbitrage execution, freeing the user from all routine operations.
