What Blink does
Blink (legally BL Research Limited) is a London-based blockchain infrastructure company founded in 2023 that operates a private mempool service for MEV (Maximal Extractable Value) protection and monetization. The company provides RPC endpoints across six networks — Ethereum, BSC, Polygon, Base, Solana, and Arbitrum — through which wallets, exchanges, RPC providers, DeFi protocols, and traders route transactions. Blink's infrastructure is reported to process over 20% of daily Ethereum transactions, settling 15 million or more transactions per day and 4 billion+ cumulatively.
The core technology is a private mempool that minimizes time-to-finalization and protects transactions from sandwich attacks and frontrunning, powered by Reth, described as the fastest Ethereum client, achieving over 4,000 requests per second, sub-150ms P95 latency, and 99.99% uptime. Adjacent product lines include a State Update Auction where searchers bid to backrun originator transactions, gas recovery that returns priority-fee overpayments (up to 90%), gas sponsorship using MEV recoveries to fund user transactions (improving landing rates up to 10% on BSC, 5% on Solana), Stake-Weighted QoS routing on Solana via partner validators controlling ~3% of active stake, Universal Gas Payments (paying Solana fees in any SPL token), and a builder-compatible API emulating Flashbots interfaces.
Blink's business model monetizes through per-transaction MEV capture and gas rebate spreads, with $0.20-$0.30 of MEV-plus-gas revenue generated per Ethereum transaction (the bulk of which is passed back to originator customers). Distribution is via a freemium self-serve portal (25 RPS free tier) plus enterprise contracts for higher volume and dedicated infrastructure. Customers named on the company site include Coinbase, Binance, Trust Wallet, Rabby Wallet, Bitget Wallet, 0x, Zerion, Ledger, Rainbow Wallet, and SafePal.

Blink competitors and assessment
Company assessmentDirect peers
- BloXRoute: BloXRoute operates a B2B private mempool and MEV-protection infrastructure for wallets and RPC providers. It is the closest direct competitor to Blink, explicitly listed by Blink on its comparison chart as offering MEV + gas refunds per transaction.
- Blocknative: Blocknative provides mempool data, transaction monitoring, and gas-orchestration infrastructure for wallets and builders. It is a direct peer in pre-chain transaction visibility and competes for the same wallet/RPC customer base Blink serves.
- dRPC: dRPC is a decentralized RPC node network serving Web3 applications with multi-chain endpoints and MEV-related features. It is a direct peer in the B2B RPC + MEV-protection niche that Blink targets.
- Flashbots: Flashbots builds MEV infrastructure including MEVBlocker (a B2C endpoint) and MEVShare (a transparent order-flow auction). Blink explicitly positions against MEVBlocker, and Flashbots is a core counterpart as the dominant Ethereum block-builder ecosystem Blink integrates with.
Broad incumbents
- Infura: Infura (ConsenSys) is one of the largest RPC and node infrastructure providers in Ethereum and IPFS. It competes for the same wallet and exchange customers with broader infrastructure offerings but without Blink's specialized MEV monetization features.
- Alchemy: Alchemy is a leading enterprise blockchain developer platform with RPC endpoints and node infrastructure across many chains. It is a broader incumbent whose wallet and exchange customers could choose Alchemy + a third-party MEV solution over Blink's integrated stack.
- Chainstack: Chainstack provides multi-chain RPC and node hosting services to enterprises. It is a broader infrastructure incumbent targeting the same wallet, exchange, and DeFi customers, but lacks a focused MEV-monetization product like Blink's private mempool.
- Ankr: Ankr offers decentralized and traditional RPC infrastructure across many chains, including a free public RPC tier. It competes in the same horizontal infrastructure layer where Blink operates, particularly via its free 25-RPS tier positioning.
Others
- Jito Labs: Jito Labs builds the dominant Solana MEV infrastructure (Jito-Solana validator client, Jito bundles, BAM). Blink is an explicit partner that leverages Jito bundles for Solana SWQoS and gas sponsorship, making Jito a closely coupled ecosystem participant rather than a direct competitor.
Emerging players
- EigenPhi: EigenPhi is a leading MEV analytics and data platform focused on order-flow insights and sandwich-attack data. It overlaps with Blink's MEV-surveillance and analytics dimension but is more data/research oriented than infrastructure oriented.
