i think in the txm getting-started changing /txm/api/interfaces/TransactionConstructorConfig to /txm/api/type-aliases/TransactionConstructorConfig fixes the docs build error

[not-reed]

why the move here?

[norswap]

Not sure why we need the zero padding here actually? Couldn't we just this.value.toString()?

[GabrielMartinezRodriguez]

Padding is needed to ensure that when we compare two strings representing bigints, the comparisons work correctly. We're not comparing numbers but strings, so without padding, the comparison would be alphabetical. For example, "9" would be considered greater than "10" because alphabetically, "9" comes after "1"

[norswap]

Just need to revert the node-jq change + possibly get rid of the padding.
