FAQ

01What is BlockRazor?

BlockRazor is global low-latency Web3 infrastructure for wallets, DEXs, trading bots, searchers, and quant trading systems. Across BSC, Ethereum, Solana, Base, and Robinhood Chain, its Streams deliver earlier mempool and chain data while Transaction Submission infrastructure helps applications send transactions with lower latency.

02What services does BlockRazor provide?

BlockRazor provides low-latency Streams for receiving mempool, block, node, and network-fee data, plus Transaction Submission infrastructure for sending transactions through RPC, Block Builder, Transaction Sending, and Gas Sponsor modes. Service availability differs across BSC, Ethereum, Solana, Base, and Robinhood Chain.

03How do I get a BlockRazor auth token?

Create a BlockRazor account, then log in. Your auth token is available on the account home page. Use it when a BlockRazor service requires auth, and keep the token private.

04Which receiving and sending services fit each use case?

Choose receiving services according to the signal or chain data the strategy needs, then pair them with the appropriate sending service. The recommendations below cover common infrastructure patterns; supported products and endpoints still depend on the target chain.

Use caseReceiving servicesSending services
Wallet / DEXBlock StreamRPC, Transaction Sending, or Gas Sponsor
Trading botsPublic Mempool, Private Mempool, or Block StreamTransaction Sending or BSC Block Builder
SearcherPublic Mempool, Private Mempool, Block Stream, or Node StreamBSC Block Builder, RPC, or Transaction Sending
Quant tradingNode StreamTransaction Sending, RPC, or BSC Block Builder
05Which blockchains does BlockRazor support?

BlockRazor currently documents services across BSC, Solana, Ethereum, Base, and Robinhood Chain. Support is service-specific: a listed chain does not imply that every Stream or Transaction Submission mode is available on that chain.

06How can BlockRazor performance claims be verified?

Use the published benchmark articles for test scope, methodology, region, and measurement date, and use the public BNB Smart Chain MEV dashboard for independently accessible historical builder statistics. Performance observations are time- and test-specific rather than universal guarantees.

07What is the BlockRazor BSC Block Builder?

BlockRazor BSC Block Builder helps searchers, trading bots, quant teams, wallets, and DEXs improve BSC transaction execution through competitive block building and globally deployed low-latency access. Its core value is providing more suitable submission paths for latency-sensitive, privacy-sensitive, and sequence-sensitive transactions, helping users improve execution stability and the chance of successful inclusion. Send Bundle, Send PrivateTransaction, and Trace Bundle support ordered execution, private submission, and performance analysis, while real-time block production statistics can be verified through the public BNB Smart Chain MEV dashboard.
