+### Precompile Limits
+
+Because of a bounded size of the zkEVM circuits, there is an upper limit on the number of calls that can be made for some precompiles. These transactions will not revert, but simply be skipped by the sequencer if they cannot fit into the space of the circuit. Read more about the [Circuit Capacity Checker](/en/technology/sequencer/execution-node#circuit-capacity-checker).
