# Trading Bot

In the high-frequency trading (HFT) ecosystems of Solana and EVM, the success of a Trading Bot depends on two dimensions: the speed of signal acquisition and the speed of transaction execution. BlockRazor provides the underlying technology and infrastructure support for Trading Bots based on these criteria. Using a Solana sniping scenario as a case study, this article introduces how BlockRazor ensures that Trading Bots maintain a leading edge in fierce on-chain competition.



#### Pain Point Analysis

**Lagging Sniping Signals**

For bots sniping newly launched tokens, data transmission through traditional public nodes suffers from severe physical latency. Due to a lack of staking, these nodes are often at the tail end of the block broadcasting routing. By the time a bot receives signals for new token deployment or liquidity addition, the optimal sniping window has often passed, causing buy-in costs to skyrocket.

**Risks and Obstacles in Transaction Execution**

* Transaction Latency: For bots pursuing sub-second settlement, slow on-chain inclusion means profit giveback for users.
* Sandwich Attacks: When performing large-scale snipes or swaps, if the bot's transaction intent is exposed, it becomes an easy target for MEV bots or malicious validators.
* Execution Barriers: When bots frequently switch wallets or operate new accounts, critical transactions may fail due to a lack of native tokens (e.g., SOL) to cover account rent or transaction fees.



#### Services

BlockRazor provides targeted services for Trading Bots to address these pain points.

**Sniping Signal Monitoring**

To solve the problem of signal lag, BlockRazor offers Geyser Stream and Shred Stream. With high-stake validators and globally distributed network, we help Trading Bots acquire sniping signals at extreme speeds. 

For Ethereum & BSC: Where pending transactions can be monitored, BlockRazor provides Public Mempool and Private Mempool for tracking pending "Smart Money" transactions, as well as New Blocks for monitoring confirmed trades.

**Multi-Mode Transaction Execution Optimization**

[**Fast**](../transaction-submission/fast/): Utilizes a globally accelerated high-performance network and SWQoS (Stake-Weighted Quality of Service) from high-stake validators to achieve the lowest possible on-chain latency.

[**Gas Sponsor**](../transaction-submission/gas-sponsor.md): Enables Trading Bot users to perform sniping transactions without holding SOL by sponsoring transaction fees and rent. Integrating Gas Sponsor brings additional benefits:

* Attract Incremental Traffic: Serves as a powerful branding and marketing tool to draw in new users and increase overall trading activity.
* Increase Revenue: Higher transaction success rates and volume lead to increased commission/fee revenue for the bot project.

[**Sandwich Mitigation**](../transaction-submission/fast/solana/send-transaction/): Provides a protection mechanism that monitors and skips blacklisted validators in real-time, shielding transaction profits from slippage erosion.

[**Bundle**](../transaction-submission/bundle/): Upon detecting a token launch transaction, the Trading Bot can use a Bundle to ensure the sniping trade is placed immediately after the launch transaction, eliminating price volatility risks caused by execution delays.
