Burn Multiple Assets from a List

Create a JSON file assets-to-burn.json:

[
  "5avjMVza8SuMhgTfzEGNWJskDELMCQk9juAAc8zeQoNa",

Notes

Warning: Burning is permanent and cannot be reversed
You must be the owner of the asset to burn it
When you burn an asset, most of the rent SOL is returned to the owner
A small amount (~0.00089784 SOL) remains to prevent account reuse
Use the --collection flag when burning assets that belong to a collection
