MEV (Valor Máximo Extraível)

The profit a block producer (leader) or sophisticated trader can extract by controlling the ordering, inclusion, or exclusion of transactions within a block — including strategies like front-running, back-running, sandwich attacks, and arbitrage. On Solana, MEV dynamics differ from Ethereum because there is no public mempool; transactions are forwarded directly to the current leader, making latency and validator relationships central to MEV capture. The Jito infrastructure provides the dominant MEV marketplace on Solana through bundles and tips.

Jito (MEV Infrastructure)

A Solana MEV infrastructure project by Jito Labs that operates a modified validator client (jito-solana), a Block Engine for bundle simulation and routing, and a tip distribution program that collects and distributes MEV tips to staked validators. Jito's client is run by a supermajority of Solana's stake-weighted validators, making its bundle and tip market the de-facto MEV layer for the network. Jito also operates a restaking and liquid staking protocol (JitoSOL) using proceeds from MEV tip redistribution.

Front-Running

An attack where an adversary observes a pending or not-yet-finalized transaction (e.g., a large swap or NFT mint) and submits a competing transaction with higher priority fees or via validator relationships to execute before the victim's transaction, profiting from predictable price impact. On Solana, transactions are not held in a public mempool the same way as in Ethereum — leaders receive transactions privately — but front-running is still possible through Jito's block engine bundle mechanism, validator collusion, or by monitoring gossip. Slippage tolerance parameters and commit-reveal schemes are the primary application-level defenses.

Ataque Sandwich

A form of MEV where an attacker places one transaction immediately before (front-run) and one immediately after (back-run) a victim's large AMM swap: the front-run buys the asset first, driving up the price the victim pays, and the back-run sells the asset immediately after the victim's transaction at the inflated price, extracting the difference as profit. On Solana, sandwich attacks are facilitated through Jito bundles, which allow searchers to atomically guarantee ordering of multiple transactions within a block. Victims can mitigate exposure by setting tight slippage tolerances (e.g., 0.1–0.5%) and using DEX aggregators that route across multiple pools to reduce single-pool price impact.

MEV Protection

Mechanisms and tools designed to shield users from harmful MEV extraction such as sandwich attacks and frontrunning. On Solana, MEV protection strategies include using private transaction submission (bypassing public RPCs), setting tight slippage tolerances, routing through MEV-aware aggregators like Jupiter that optimize execution, and submitting transactions via Jito bundles with ordering guarantees. Some wallets and dApps integrate MEV protection by default to improve user outcomes.

Mainnet Beta

Solana's primary production cluster where real SOL and real economic activity occur; the "beta" designation reflects the network's ongoing protocol development despite being fully live since March 2020. It uses the same architecture as other clusters but with real validator stakes, live staking rewards, and permanent on-chain state. All production dApps, tokens, and NFTs exist on Mainnet Beta.

Devnet

A persistent public Solana cluster intended for application development and testing, running the same software version as Mainnet Beta but with no real economic value. Devnet SOL can be freely airdropped via the CLI or faucet APIs, and the ledger may be reset periodically by Solana Labs. Developers use Devnet to test programs and integrations before deploying to Mainnet Beta.

Rede

Testnet

A public Solana cluster used primarily by the Solana core team and validators to test new software releases, performance benchmarks, and network upgrades under real network conditions before they reach Mainnet Beta. Testnet SOL has no monetary value, and the ledger is reset more frequently than Devnet; it is less suitable for application development and more suited for validator operators validating their infrastructure.

TPS (Transações por Segundo)

The rate at which a Solana cluster processes and commits transactions; Solana's theoretical maximum exceeds 65,000 TPS due to its parallel execution model, though real-world sustained throughput on Mainnet Beta typically ranges from 2,000–5,000 non-vote TPS under normal load. Vote transactions (used for consensus) make up a significant portion of all on-chain activity and are counted separately. High TPS is enabled by Proof of History timestamps, Sealevel parallel execution, and Gulf Stream mempool-less forwarding.
