Outbound Transaction Ok

This event is used to communicate the successful "burning" of existing tokens in the Ledger module.

Event Signature

An Outbound Transaction Ok event has the following form:

{
  "id": "{eventId}",
  "pubkey": "{ledgerPubkey}",
  "created_at": timestamp,
  "kind": 1112,
  "tags": [
    ["p", "{minterPubkey}"],
    ["p", "{minterPubkey}"],
    ["e", "{outboundTransactionEventId}"],
    ["t", "outbound-transaction-ok"],
    ...,
  ],
  "content": "{outboundTransactionOkContent}",
  "sig": "{signature}"
}

Note:

• the .pubkey is the Ledger module's pubkey,
• the .kind field is 1112 (ie. a regular event),
• both "p" tags point to the URLx module's pubkey (ie. the minter),
• the "t" tag sub-kind is outbound-transaction-ok.

The content itself is the JSON serialization of an object of the following form:

{
    "tokens": {
        "{tokenName}": tokenAmount,
        ...,
    },
    "memo": "{memoString}"
}

An example TypeScript type definition for this event's content is:

type OutboundTransactionOkContent = {
    tokens: Record<string, bigint>,
    memo?: string,
};

Not that both of these are equal to those for Outbound Transaction Start events.
