Ridiculously cheap event logs

Shadow events are 1,000x cheaper than the gas costs your users pay to emit events.

Shadow Starter plan pricing

Reduce gas fees by up to 12% on every transaction.

Event logs are expensive. Make your protocol more competitive for users by moving events to an offchain shadow fork that mirrors mainnet in realtime.
