In the document:


We are told: "JSON strings are represented as CBOR strings" How can I interpret these?

The source of th eformat of those appears to be here: https://www.rfc-editor.org/rfc/rfc7049

Here is an example of one from a transaction in the tx_metadata table of cardano-db-sync


enter image description here

...there is this: https://github.com/CardanoSharp/CBOR

A good tool for manually analyzing CBOR is https://cbor.nemo157.com/

What they probably meant by "JSON strings are represented as CBOR strings" is that typical JSON objects can be represented in tx-metadata using CBOR

  • I am trying to figure out how a value like this one, in the object, is a value that decodes to a wallet address: BAED3AE13D7EEB93BB4B4F44E10AFF9F1FC052869F4A1CD1501BE928 Dec 2, 2022 at 7:31
  • I don't think there are any easy-to-use online tools for converting the hex of, I'm assuming, a pubkeyhash into a bech32 encoded address. You would have to use a library. Eg. with Javascript and Helios: let isTestnet=true;helios.Address.fromPubKeyHash(isTestnet, helios.PubKeyHash.fromHex(" BAED3AE13D7EEB93BB4B4F44E10AFF9F1FC052869F4A1CD1501BE928")).toBech32() which results in addr_test1vzaw6whp84lwhyamfd85fcg2l703lszjs60558x32qd7j2qnwhmq3 Dec 2, 2022 at 12:18
