BlockRazor is a leading Web3 transaction infrastructure provider built on top-tier distributed network communication technology and architecture. Designed to serve a diverse range of on-chain participants — including wallets, decentralized exchanges (DEXs), trading bots, searchers, and quantitative trading systems — BlockRazor delivers reliable, low-latency infrastructure across Ethereum, BSC, Solana, and Base. Its three core service pillars help clients achieve optimal trade execution at every layer of the stack.

Core Service Pillars

Transaction Submission

Multiple submission modes — RPC, Gas Sponsor, Fast, and Bundle — tailored to your exact speed, cost, and MEV-protection requirements.

Streams

High-performance data streams including Mempool, Block Stream, Network Fee Stream, and Node Stream for real-time on-chain awareness.

Block Builder

BSC block building service based on PBS architecture with a historical cumulative block production rate of 37%, ranking first across the entire BSC chain.

Transaction Submission

BlockRazor offers four distinct transaction submission modes, each engineered for a different client profile:
  • RPC — Standard JSON-RPC methods with integrated MEV protection and support for real-time rebates.
  • Gas Sponsor — Gas fee sponsorship for users who lack sufficient native tokens, dramatically improving onboarding and trading experience.
  • Fast — A global acceleration network that boosts on-chain transaction speeds, ideal for users with extreme latency requirements.
  • Bundle — Execute transactions within the same block as a “signal transaction” via Bundles, built specifically for backrunning, copy trading, and token sniping.

Streams

BlockRazor’s streaming layer delivers real-time on-chain data with minimal latency across multiple feed types:
  • Mempool — Low-latency pushes of pending transactions, enabling users to monitor signal transactions for backrunning, copy trading, and sniping in real time.
  • Block Stream — Low-latency block data so trading programs can monitor confirmed signal transactions or other transactions as they land.
  • Network Fee Stream — Real-time pushes of Gas Price, Priority Fee, or Tips based on recent historical block data.
  • Node Stream — Synchronize data with full nodes for low latency and keep the world state updated in real time.

Block Builder

BlockRazor’s Block Builder provides BSC block building services based on the PBS (Proposer-Builder Separation) architecture. Deployed across multiple regions worldwide with low-latency communication to validators, Block Builder runs multiple algorithms to maximize block value and construct competitive blocks. BlockRazor’s Block Builder has achieved a historical cumulative block production rate of 37%, ranking first across the entire BSC chain.
Track the real-time block production rate on the BNB Smart Chain MEV Stats dashboard powered by Dune Analytics.
