Solayer Chain introduces jumbo transactions — an extended transaction type designed for high-complexity operations, particularly hook-based execution that exceeds standard transaction size limits.

​
What Are Jumbo Transactions?

A jumbo transaction enables:
  • Execution across thousands of accounts in a single transaction
  • Thousands of instructions within a single execution pipeline
  • Atomic deployment of multiple programs, reducing state inconsistencies
This supports complex multi-step operations that would otherwise require splitting across multiple transactions.

​
Fee Model

Jumbo transactions use exponential fee scaling — as transaction size grows, fees grow exponentially. This ensures fair resource allocation and prevents excessive transaction bloat.

​
Use Cases

Hook-based execution Hooks can perform high-volume state updates across multiple smart contracts in a single transaction, without splitting logic across multiple calls. Batch operations Multi-asset swaps, cross-chain function calls, and on-chain auctions can be batched into a single atomic operation, reducing latency and fees. Program deployment & upgrades Deploy multiple programs in one transaction to ensure synchronized updates and direct inter-program calls during deployment.
