Recommendations
Here's a list of recommendations to ensure the best experience for searchers and validators.
Searcher
Time Synchronization
Location
For low-latency access, we strongly recommend provisioning your servers as close as possible to ours. See Block Engine for address to check latency.
Bundle Assembly
Ensure that your tip is an instruction in the last transaction.
Run a balance assertion after tipping to ensure the transaction doesn't result in losing money.
Provide slot range checks to assert bundles are landing within the range you expect them to land in.
To help increase the performance of Solana, randomly choose one of eight tip accounts to transfer SOL to in order to maximize chance of parallelism.
Cross Region
Cross region functionality is provided for searcher convenience. Ideally, searchers run one instance per region to minimize latency. However if latency is not a primary concern, then cross-region requests simplify management.
The current cross-region features are available:
SendBundle
Bundles are automatically sent cross region to upcoming leaders running Jito Solana
GetUpcomingLeaders
Searchers can request the leader slots that are coming up for validators running Jito Solana
SubscribeMempool
Searchers can request mempool transactions from multiple regions at once
GetRegions
Returns the regions where block engine is available
