Use hyperlane-decode-token-message to decode a base-64-unpadded encoded Hyperlane Token Message into an object containing recipient, amount, and chainId information.

This token message format is proprietry to Kadena and different from the standard Hyperlane token packing. For reference: (see EVM Implementation )

Basic syntax

To decode a Hyperlane Token Message using hyperlane-decode-token-message, use the following syntax:

(hyperlane-decode-token-message x)

Arguments

Name	Type	Description
x	string	A base-64-unpadded encoded Hyperlane Token Message

Return value

The hyperlane-decode-token-message function returns an object with the following fields:

Field	Type	Description
recipient	GUARD	The recipient of the token message
amount	DECIMAL	The amount of tokens
chainId	STRING	The chain identifier

Examples

Here's an example of using hyperlane-decode-token-message to decode a Hyperlane Token Message:

pact> (hyperlane-decode-token-message "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHsABHsicHJlZCI6ICJrZXlzLWFsbCIsICJrZXlzIjpbImRhMWEzMzliZDgyZDJjMmU5MTgwNjI2YTAwZGMwNDMyNzVkZWIzYWJhYmIyN2I1NzM4YWJmNmI5ZGNlZThkYjYiXX0")
{"amount": 0.000000000000000123,"chainId": "4","recipient": KeySet {keys: [da1a339bd82d2c2e9180626a00dc043275deb3ababb27b5738abf6b9dcee8db6],pred: keys-all}}

In this example, the function decodes the provided base-64-unpadded string and returns an object containing the decoded information:

• The amount is 0.000000000000000123
• The chainId is "4"
• The recipient is a KeySet with one key and a keys-all predicate
