Arbitrage Basics: How to Build a Crypto Arbitrage Bot

Tue, 21 Jul 2026 14:26:00 +0000

Welcome Back to Arbitrage Basics

This is part three of our arbitrage series, and it is the one where the math starts running. Part one built a triangular arbitrage checker for Uniswap V2 and walked through pairs, reserves, and the exact getAmountOut formula. Part two generalized detection with graph theory: tokens become vertices, pairs become edges weighted by negative log exchange rates, and Bellman-Ford surfaces profitable cycles of any length as negative cycles. Both posts end at the same place, a function that takes fresh reserves and returns candidate trading loops.

What Is a MEV Searcher? Infrastructure, Latency, and Whether You Need Your Own Node

Mon, 20 Jul 2026 13:47:00 +0000

If you have read anything about MEV, you have met the word “searcher”. It is the working job title of everyone actually running the bots: the arbitrageur closing a price gap between two DEX pools, the liquidator watching health factors on a lending market, the operator whose bundle landed one block ahead of yours. The term gets used constantly and defined rarely. This post fixes that. It covers what a MEV searcher actually is, where they sit in Ethereum’s block-building pipeline, which strategies they run, what their infrastructure looks like in practice, and then the question almost everyone asks next: do you need to run your own node to compete?

What Is ePBS? Ethereum's Enshrined Proposer-Builder Separation (EIP-7732), Explained

Mon, 20 Jul 2026 08:12:00 +0000

ePBS stands for enshrined proposer-builder separation. It is the change, specified in EIP-7732, that moves Ethereum’s block-building marketplace out of trusted off-chain middleware and into the protocol itself. Today, a validator who wants a professionally built block hands the deal to a relay, an unpaid third party that both sides simply have to trust. Under ePBS the builder’s signed bid goes into the beacon block directly, payment is enforced by consensus, and the relay’s trust role disappears. It ships as the headline consensus change of Glamsterdam, the hard fork after Fusaka, currently targeted at mainnet in the second half of 2026.

Why MEV Is a Latency Game: The Case for Co-located Ethereum Nodes

Tue, 23 Jun 2026 09:00:00 +0000

Most write-ups about MEV focus on strategy: arbitrage, liquidations, sandwiching, backruns. Strategy is necessary, but it is not what separates a profitable searcher from a spectator. The deciding factor is usually time. By the time a pending transaction reaches you over a public RPC gateway, has been parsed, evaluated, and answered with a fresh state read across the network, the opportunity may already belong to someone closer to the chain. This post is about where those milliseconds go and how co-located node access closes the gap.

How to Access the Ethereum Mempool: Streaming Pending Transactions From a Co-located Node

Sat, 20 Jun 2026 14:00:00 +0000

Every transaction spends a moment in limbo between “broadcast” and “mined”. That waiting room is the mempool, and it is where a lot of the interesting work in Ethereum happens: a searcher spots an arbitrage before it lands, a bot front-runs a large swap, a liquidation watcher sees the transaction that will tip a position underwater. If you want to act on a transaction before it is final, you have to read the mempool.
