+- `SettlementBackend` defines how a final zk-proof is settled. All chains connected to the AggLayer use the `agglayer` value.
+- `AggLayerTxTimeout` is the interval a transaction is mined on the AggLayer.
+- `AggLayerURL` is the url of the agglayer service. Supplied by Polygon.
+- `SequencerPrivateKey` is the private key of the trusted sequencer. Only a CDK trusted sequencer can interact with the AggLayer.
+- `SenderAddress` is the address specified by the aggregator when it creates a proof. Supplied by Polygon. Supplied by Polygon.
