The project I'm working on has been hijacked and rugged by the ex-developer who had the authority account. Long story-short, he minted new tokens, then he emptied the liquidity pool.

We still have the owner account so I tried to change the authority wallet, but it failed with this error:

RPC response error -32002: Transaction simulation failed: Error processing Instruction 0: custom program error: 0x4 [5 log messages]

This is the CLI line I used for trying to change the mint authority:

spl-token authorize Token_Address mint New_Authority_Address

I looked up the 0x4 error and it looks like it means "/// Owner does not match." But this is not true. Running "spl-token account-info token_address" shows our wallet as the Owner.

I also tried running "spl-token revoke token_account_address" but it returns:

No delegate on account

Does anyone know how I can update the authority account?

No delegate on account means that there is no delegate to revoke on the token account.

spl-token authorize Token_Address mint New_Authority_Address would fail with Owner does not match because whatever mint you're trying to update is not owned by the address provided.

I would recommend transferring to a new token account and working from there. Assume anything else compromised.

  • The ex-developer&thief was the one who minted the old token. We created a new token eventually. I was hoping that we could somehow regain control of the old one to at least change its symbol and name. Thank you very much for your answer!
