Key Takeaways
- Solana transactions can now reach 4,096 bytes.
- The former limit was 1,232 bytes.
- V1 can combine complex work in one action.
- Legacy and V0 wallet transactions still work.
- Large transactions may face higher priority fees.
Solana activated its txv1 feature on mainnet at the start of epoch 1035 on September 15, raising the maximum transaction size from 1,232 bytes to 4,096 bytes.
