You don’t need to run a trading firm or a search operation to benefit from professional transaction infrastructure. Individual traders on BlockRazor get access to the same MEV-protected submission paths, global acceleration network, and atomic bundle execution that institutional users rely on — at no cost from the moment they register. Whether you’re swapping tokens, minting NFTs, or executing a time-sensitive trade, BlockRazor’s free tier gives you the tools to compete on equal footing.Documentation Index

What you get from day one
Every new BlockRazor account unlocks multi-mode transaction submission across Solana, BSC, Ethereum, and Base with zero upfront cost and no credit card required. The four modes available immediately after registration are:RPC — MEV Protection
Use
eth_sendRawTransaction through BlockRazor’s protected relay on BSC and Ethereum. Your pending transactions stay private from searchers until they land on-chain.Fast — Global Acceleration
Route transactions through BlockRazor’s high-performance global network for the fastest possible confirmations on Solana, BSC, and Base.
Bundle — Atomic Execution
Submit bundles on BSC and Ethereum to execute your transaction in the same block as a target transaction — useful for sniping or reacting to on-chain events.
Block Builder — Direct Inclusion
Submit private transactions and bundles directly to the BlockRazor BSC Block Builder, which has a 37% cumulative block production rate on BSC.
Core benefits for individual traders
MEV protection — stop leaving money on the table
When you submit a transaction through a standard public RPC, it sits in the public mempool where searchers can see it and front-run or sandwich it before it confirms. BlockRazor’s RPC mode keeps your transaction private until block inclusion, preventing this class of value extraction entirely. For high-value swaps and time-sensitive trades, this protection can be worth more than the cost of any subscription.
Faster confirmations with the global acceleration network
Fast mode connects to BlockRazor’s distributed global relay and routes your transaction directly to highly staked validators. On Solana you get up to 3 TPS by default; on BSC and Base up to 10 TPS — more than enough for active individual trading without any subscription required.
Gas Sponsor — trade before you hold gas
Gas Sponsor lets a platform or dApp cover your gas fee, meaning you can execute your first transaction on a new chain without needing to bridge native tokens first. As an individual trader, look for dApps and wallets that have integrated BlockRazor Gas Sponsor to enjoy this benefit automatically.
Upgrade only when you need to
The free tier is designed to cover the needs of most individual traders indefinitely. If your volume or strategy complexity grows, BlockRazor’s subscription services scale with you — from individual service add-ons to multi-chain packages — with discounts of up to 20% for longer commitment periods.
