I Hit the 1,232-Byte Wall So You Don't Have To
The article discusses the limitations of Solana's transaction size, specifically the 1,232-byte cap. The author shares their experience of hitting this limit while developing a batch transfer tool for sending SOL to multiple recipients. They explain how using Address Lookup Tables (ALTs) can help optimize transaction sizes and accommodate more complex operations.
- ▪Solana transactions have a hard cap of 1,232 bytes, which is based on IPv6 packet size requirements.
- ▪The author encountered this limit while trying to send SOL to 20 recipients in a single transaction.
- ▪Using Address Lookup Tables (ALTs) allowed the author to significantly reduce transaction size and add more complexity.
