# Gas Optimizations

With the release of pooling there have been two major improvements that will result in gas savings; Submit Multiple Assertions and Claim Multiple Rewards.

Submit Multiple Assertions ([testnet example](https://sepolia.arbiscan.io/tx/0x122dbd9bad0b3b184ad3161a343333f0fdb23beb7466dd448168a43fbc3b690d)) will allow an Operator to batch together all of the assertions for a challenge in one transaction. So the larger a pool gets, the more keys that will be able to participate in a challenge, the larger the savings will be to assert for them all in a single transaction.

Claim Multiple Rewards ([testnet example](https://sepolia.arbiscan.io/tx/0xb52825b3db61f3ea36f763fab1f41606c1806c4767d7263b400795a2ee866ea9)) will allow an Operator to batch together all of the claims for a challenge in one transaction. Similar to above, the more keys an Operator runs for a pool, the bigger the savings.
