Soroban's fee structure uses granular resource metering to price compute, memory, and storage independently, enabling more efficient block utilization and lower validator costs than traditional gas-based systems like Ethereum's.
Soroban scales through a novel fee model that charges developers based on individual resource consumption rather than a single gas metric. Unlike Ethereum's EVM which converts compute, memory, and storage into one gas value, Soroban exposes each resource type separately, allowing blocks to be fully utilized and preventing wasted capacity. The platform combines this with state expiration to prevent ledger bloat, fine-grained metering to track resource use, and per-transaction resource limits voted on by validators. This design keeps validator costs low (8GB RAM vs Solana's 256GB), incentivizes efficient contract development, and ensures fair pricing for users.
