Address Lookup Table

中文

Shows how to fetch an Address Lookup Table (ALT), attach it to a PumpFun transaction, and submit after receiving a sol-parser-sdk gRPC event.

This is a live-transaction template. Set PRIVATE_KEY, replace use_your_lookup_table_key_here, and configure RPC and gRPC before running.

export GRPC_ENDPOINT=https://your-yellowstone.example
export GRPC_AUTH_TOKEN=optional-token
cargo run --package address_lookup

An ALT reduces message size but does not make stale pool state valid. Fetch and cache known ALTs before the event hot path. The current example initializes the trading client after an event and is therefore an API demonstration, not the recommended low-latency structure.
