under [https://polkadot.js.org/apps/#/chainstate/constants](https://polkadot.js.org/apps/#/chainstate/constants) i get value u128. what does that mean? it should be something simple. in the beginner guide : [https://wiki.polkadot.network/docs/build-protocol-info#existential-deposit](https://wiki.polkadot.network/docs/build-protocol-info#existential-deposit) "You can always verify the existential deposit by checking the [chain state](https://polkadot.js.org/apps/#/chainstate) for the constant balances.existentialDeposit" so where to look? thank you.
