## Explanation of fields: ### Additional Encryption
``` The encryption used by DMs in NIP-04 can be utilized to further protect the base64 encoded data in the `content` field. This adds an extra layer of protection from those attempting to get information regarding transaction creation via nostr event data similar to how NIP-46 and NIP-47 implement NIP-04.
id: The sha256 hash of the serialized event payload.
pubkey: The public key of the creator of the event. - **nip04_encrypt**
created_at: A Unix timestamp indicating the time when the event was created. - params [`pubkey`, `plaintext`]
kind: An integer value used to indicate the type of event. For PSBTs, the kind is set to 1174. - result `nip4 ciphertext`
tags: An array of tags to capture additional information about the multisig transaction: - **nip04_decrypt**
“e”: (optional): the 32 byte lowercase hex encoded sha256 event id of a prior event id. Only required when replying. - params [`pubkey`, `nip4 ciphertext`]
“magic”: the 4 byte hex representation of the network that the transaction belongs to. - result [`plaintext`]
“relays”: (optional) tag provides relays to broadcast the transactions.
content: PSBT encoded as base64. Note that `pubkey` is a hex-encoded strings.
sig: The signature of the sha256 hash of the serialized event data, which is the same as the "id" field.
```
### Note: ### Note:
The "e" field is optional and is used when replying to a prior event.
The "relays" field is optional and can be used to provide relay URL recommendations to clients for improved censorship resistance. The "relays" field is optional and can be used to provide relay URL recommendations to clients for improved censorship resistance.
