encodeLabelhash

Encodes a hash as an ENS encoded label

encodeLabelhash

Encodes a hash as an ENS encoded label. This is the inverse of EncodedLabelToLabelhash.

Import

import "github.com/ChefBingbong/viem-go/utils/ens"

Usage

import "github.com/ChefBingbong/viem-go/utils/ens"


// Encode a labelhash
encoded := ens.EncodeLabelhash("0x4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0")
// "[4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0]"


// Works without 0x prefix
encoded = ens.EncodeLabelhash("4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0")
// "[4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0]"

Returns

  • Type: string

The encoded label in the format [<64 hex chars>].

Parameters

hash (required)

  • Type: string

The hash to encode. Should be 64 hex characters (with or without 0x prefix).

encoded := ens.EncodeLabelhash("0x4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0")
// "[4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0]"

Encoded Label Format

Encoded labels are in the format:

[<64 hex characters>]

For example: [4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0]

Notes

  • Removes 0x prefix if present
  • Used to represent labelhashes in ENS names
  • Encoded labels are preserved during normalization
  • Inverse operation of EncodedLabelToLabelhash
