<p>If all assets have a <code>policyId</code> and an <code>assetName</code>, what is the <code>policyId</code> and <code>assetName</code> of ADA?
I'm assuming the <code>assetName</code> is ADA, but seeing as how ADA is the <a href="https://cardano-ledger.readthedocs.io/en/latest/explanations/policies.html#principal-asset" rel="nofollow noreferrer">principal asset</a> of Cardano, what is the <code>policyId</code>?</p>

If all assets have a `policyId` and an `assetName`, what is the `policyId` and `assetName` of ADA?
I'm assuming the `assetName` is ADA, but seeing as how ADA is the [principal asset](https://cardano-ledger.readthedocs.io/en/latest/explanations/policies.html#principal-asset) of Cardano, what is the `policyId`?

Yes, all assets should have a policyId.

In case of ADA:

* policyId ([adaSymbol](https://github.com/input-output-hk/plutus/blob/0836d25ecc469d8a3494bf6db10fc8404da522ec/plutus-ledger-api/src/Plutus/V1/Ledger/Ada.hs#L48)) is an `emptyByteString` = ""
* assetName ([adaToken](https://github.com/input-output-hk/plutus/blob/0836d25ecc469d8a3494bf6db10fc8404da522ec/plutus-ledger-api/src/Plutus/V1/Ledger/Ada.hs#L53)) is an `emptyByteString` = ""
