Solana MEV is the profit validators and specialized traders can capture by controlling the order in which transactions land in a block. Most of it flows through one piece of infrastructure, Jito, and most of it is harmless arbitrage. The…
There are two main ways to stake SOL: native staking, where you delegate directly to a validator, and liquid staking, where you deposit SOL and get a token back that you can keep using. Both pay you a share of…
Reading data from a blockchain sounds simple until you try it. A smart contract emits events, but pulling those events back out in a useful order — filtered, aggregated, ready for a frontend — is slow and awkward if you…
A Jito bundle is a group of up to five Solana transactions that execute together, in a fixed order, as all-or-nothing. If any transaction in the bundle fails, none of them land. That guarantee is what makes bundles useful for…

A Firo explorer is a website that lets you look up blocks, transactions, and transparent addresses on the Firo network without running a node yourself. Firo is a privacy coin, so an explorer here shows less than it does on…
