Trading bots live and die by milliseconds. Whether you are running a copy-trading strategy, chasing a backrun opportunity, or executing a token snipe, the difference between profit and loss is almost always latency — at the submission layer, the signal layer, or both. BlockRazor was built for exactly this environment. Its global acceleration network, atomic bundle execution, and low-latency mempool streams give your bot the infrastructure it needs to compete at the frontier of on-chain trading.

​
Why trading bots choose BlockRazor

Fast Transaction Submission

Propagate transactions through BlockRazor’s globally distributed acceleration network for the lowest possible confirmation latency on Solana, BSC, and Base.

Bundle Execution

Submit a group of transactions that execute atomically within the same block as a target “signal” transaction — essential for backrunning and copy trading.

Mempool Streams

Receive low-latency pushes of pending transactions the moment they enter the network, giving your bot the earliest possible signal to act on.

​
Core benefits

1

Global acceleration for minimum latency

Fast mode routes your transactions through BlockRazor’s high-performance global network and connects directly to highly staked validators. On Solana you get up to 3 TPS by default; on BSC and Base up to 10 TPS. This is the submission path to choose when raw speed to confirmation is your primary requirement.
2

Atomic bundle execution for complex strategies

Bundle mode lets you pair your bot’s transaction with a target transaction and guarantee they land in the same block, in the correct order. If your transaction cannot be included alongside the target, the entire bundle reverts — protecting you from partial execution and wasted gas. This is the backbone of backrunning, copy trading, and token sniping strategies.
3

Mempool signals for earliest detection

BlockRazor’s Mempool stream delivers pending transaction data with sub-millisecond push latency. Your signal-detection logic sees new transactions before they are widely propagated, giving your bot the time it needs to construct and submit a response bundle.

Integration patterns

Fast mode on BSC uses the standard eth_sendRawTransaction interface. Include the tip to BlockRazor’s designated address inside the transaction itself.
curl -X POST https://rpc.blockrazor.io/bsc/<api-key>/fast \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_sendRawTransaction",
    "params": ["0x<signed_tx_hex>"],
    "id": 1
  }'
Combine a Mempool stream subscription with Bundle submission for the tightest end-to-end loop: detect the signal transaction the moment it is broadcast, immediately construct your bundle, and submit it through the Bundle endpoint so it reaches the block builder with minimum propagation delay.
