BlockRazor’s pricing system has been fully upgraded to give users precise control over what they pay for. The original multi-chain, multi-tier system has been split into independent per-chain, per-service subscriptions — lowering the entry threshold while making it easy to build a stack that matches your exact needs. Services can be purchased individually or bundled together at a reduced rate.Documentation Index

New registered users can access multi-mode transaction sending services on Solana, BSC, Ethereum, and Base at zero cost. See the New Registered Users section for details on included methods and rate limits.
Subscription Service
Personalized
Users can freely combine and purchase services across chains. Stream-type services support configuring quantities or traffic package specifications and also support daily purchases. Visit the BlockRazor Pricing page to configure and purchase.- BSC

Package
Rather than assembling individual services, users can purchase the BSC Package for a lower all-in price. The package consolidates the most commonly used BSC services into a single subscription.The BSC Package is priced at $1,250 / month — a significant saving compared to purchasing the included services separately.

New Registered Users
New registered users receive free access to multi-mode transaction sending services across Solana, BSC, Ethereum, and Base — no subscription required. The free tier covers four service modes, each with specific methods and rate limits.RPC — Standard JSON-RPC Methods
RPC — Standard JSON-RPC Methods
The RPC mode provides the chain-native
eth_sendRawTransaction method and other standard JSON-RPC methods.| Chain | Methods | Limit |
|---|---|---|
| BSC | eth_sendRawTransaction, other JSON RPC methods | — |
| Ethereum | eth_sendRawTransaction, other JSON RPC methods | — |
| Base | eth_sendRawTransaction | 1 tx / 5 seconds |
Fast — Global Acceleration Network
Fast — Global Acceleration Network
Fast mode leverages BlockRazor’s globally distributed acceleration network and highly staked validators to provide rapid on-chain transaction processing. In Fast mode, the tip must be forwarded to a designated address within the transaction itself.
| Chain | Methods | Limit |
|---|---|---|
| Solana | Send Transaction, Send Transaction v2 | Default 3 TPS |
| BSC | eth_sendRawTransaction, eth_sendRawTransaction v2 | Default 10 TPS |
| Base | eth_sendRawTransaction | Default 10 TPS |
New registered users can also use
SendTx — the no-tip variant within the Fast-Tx service — with a limit of 10 txs / 5 seconds and 10 txs / day.Bundle — MEV and Orderflow Auction
Bundle — MEV and Orderflow Auction
Bundle mode allows project builders to send bundles and allows Searchers to send bids in the orderflow auction.
| Chain | Methods | Limit |
|---|---|---|
| BSC | eth_sendMevBundle (project builders), eth_sendMevBundle (Searcher) | — |
| Ethereum | eth_sendBundle (project builders), eth_sendBid (Searcher) | — |
Block Builder — BSC Block Building
Block Builder — BSC Block Building
Block Builder is BlockRazor’s BSC block building service. Based on global deployments and low-latency communication with validators, Block Builder runs various block building algorithms to achieve a high success rate in block production. New users can submit bundles and private transactions to Block Builder for free.
