Transaction Fee Management Solutions

Raiku provides a coordination layer for Solana that replaces probabilistic mempool inclusion with deterministic blockspace reservations. Rather than competing solely on priority fees with uncertain outcomes, developers and institutions use Raiku's Ahead-of-Time (AOT) reservation mechanism to bid for upcoming block slots before those slots are produced. Upon winning a reservation, they receive a pre-confirmation guarantee that their transaction will land in a specific future block, reducing execution latency to 30–50 milliseconds and eliminating the retry loops most applications currently require. The system also supports Just-in-Time (JIT) MEV bundle processing for reactive workloads such as liquidations, arbitrage, and real-time price updates where timing cannot be committed in advance. Raiku's transparent auction model makes block ordering auditable based on explicit bids rather than private searcher relationships, reducing predatory MEV. The Ackermann-node scheduler network sits between applications and validators, coordinating reservations, managing burst demand, and enforcing each commitment without replacing Solana's existing validator software.

bloXroute occupies a significant position in Solana's transaction prioritization stack by accepting and routing bundles directly to validators capable of including multiple transactions atomically. Bundle submission is the mechanism MEV searchers use to guarantee transaction ordering — ensuring arbitrage or liquidation logic executes in a specific sequence without displacement by competing transactions. bloXroute's gateways deliver these bundles through the BDN faster than standard gossip. The validator-side tooling extends this into fee capture. bloXroute's validator solutions establish private transaction channels that protect order flows from front-running while letting operators selectively accept bundles based on routing configurations. This positions bloXroute alongside other MEV infrastructure providers in giving both searchers and sequencers structured tools to compete for priority fee revenue within Solana's fast-finality environment.

Gelato's Paymaster and Bundler infrastructure delivers a complete account abstraction stack for sponsoring gas fees on behalf of users or letting users pay in ERC-20 tokens rather than native gas. Supporting both ERC-4337 user operation bundling and EIP-7702 EOA delegation, the platform enables gasless onboarding flows across more than 100 EVM-compatible chains — and explicitly Solana, where the Turbo Relayer handles fee sponsorship without users needing to hold SOL. Gemini Wallet uses Gelato to make every transaction gasless across 100+ EVM chains, while Infinex delivers gasless and signless UX across 30+ chains through the same relay infrastructure. The Turbo Relayer, Gelato's latest-generation relay product, cuts the conventional relay round-trip from one to five seconds down to roughly 300 milliseconds on supported chains, reducing gas overhead by 30-90% compared to prior relay implementations — with EIP-7702 execution paths seeing the largest savings. By abstracting gas management through gas tank operations, global node distribution, automatic failover, and managed Paymaster infrastructure, Gelato removes one of the highest-friction onboarding barriers facing consumer Web3 applications today.

BAM is Jito Labs' transaction scheduling system that moves ordering logic outside the validator into a distributed network of tamper-proof AMD SEV-SNP hardware enclaves. Transactions enter encrypted TEE nodes, are scheduled there, and emerge as ordered microblocks that validators execute in strict FIFO sequence with no reordering allowed after the TEE output. Cryptographic attestations prove the scheduling algorithm ran faithfully, directly addressing sandwich attacks and front-running by ensuring the entity ordering transactions can never act on what it sees. BAM's plugin system enables Application-specific Controlled Execution, letting applications apply custom sequencing logic before transactions reach validators. The Maker Priority Plugin elevates price update transactions to the top of each 50ms batch and automatically deduplicates stale quotes. Use cases include cancel-before-take policies, time-in-force enforcement, liquidation sequencing priority, and dark pool execution, with plugin fees distributed among node operators, validators, stakers, and the Jito DAO treasury.

MevX routes Solana trades through the Jito block engine, bundling them with a small tip and submitting directly to Jito validators to prevent sandwich attacks. On Ethereum, Flashbots Protect keeps transactions in a private mempool until block inclusion by an ethical builder. MEV protection is a core differentiator, and users configure priority fee tips and slippage tolerance per trade to control execution cost and ordering. Sniper V2 depends on rapid transaction submission to secure early positions when token liquidity events open across Pump.fun, Raydium, Launchlab, and Boop.fun simultaneously. Each snipe session lets users set slippage tolerance, priority fee tips, and per-snipe spending limits. MevX charges a 0.8% fee on Solana trades, with user ranking tiers that affect rates on other supported chains including Ethereum, BNB Chain, Base, Monad, and TRON.
