Maybe we should have done this before, but can you please repost your comment in the ETH Magicians. We have active users with e.g. Otterspace out there so they might rely on this property.

Ah! I see the point. Without a nonce, the signature can be reused. Wouldn’t it be better to prevent reissuance of an ABT using same signature instead of making an ABT itself unequippable after burn?

@rotcivegaf @TimDaub is there any interest in pursuing this pull request, or can I close it?

[rotcivegaf]

I think this idea is being worked on in another EIP

Beyond that the PR is correct

[TimDaub]

I think if this was to go into the spec, then @rotcivegaf you should also provide a section in the rationale. And additionally, it‘d be ideal if we could implement it in the reference implementation too.

I am closing this pull request because we are in the process of separating EIPs and ERCs into distinct repositories. Unfortunately, as far as we are aware, GitHub does not provide any tools to ease this migration, so every pull request will need to be re-opened manually.

As this is a PR to create / modify an ERC, I will kindly ask you to redirect this to the new repository at ethereum/ERCs. We have prepared a guide to help with the process.

If there is relevant history here, please link to this PR from the new pull request.

On behalf of the EIP Editors, I apologize for this inconvenience.
