- Chain ID was not validated
proxyd, a custom JSON-RPC load balancer, which restricts the volume of requests the main sequencer has to manage.- Transactions are discarded before contributing to the rate limit if the nonce is lower than the account’s current nonce
- LayerZero’s Executor and Oracle accounts, Across’ Relayer, Synapse’s Executor, Hop Bridge’s ETH Bonder, LayerSwap’s Relayer, Aave’s Deployer, Uniswap’s Deployer, and even many of Optimism’s multisig owners and the usual wallet transaction executor
