What's the quickest way through RPC call to check if an address need 0.257 xtz burnt in order to pay for storage?

1 Answer 1


If the balance is exactly 0, then it needs the burn. /chains/main/blocks/head/context/contracts/${addr}/balance

  • Do I need to check also if it's been at least a cycle with balance 0? Or is it immediately inactive and needs the burn? Mar 31, 2020 at 16:20
  • According to the other question you asked, immediately inactive. You can test this by using the tezos-client in --dry-run mode and see if the client adds an additional fee.

    If the balance is exactly 0 AND it's not a delegate and not a KT address ;)
