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.

Send SOL to 20 recipients in one transaction. Simple, right? Wrong. The RPC rejected my transaction with: Transaction too large: 1400 > 1232 I had no idea what 1232 meant. Now I do. The Limit Every Solana transaction — transfer, swap, mint, everything — has a hard cap: 1,232 bytes. Not 1,232 lines of code.
