BEP-82: Token Ownership Changes

1. Summary

This BEP describes the changes related to the token owner who issued a token on Binance Chain.

2. Abstract

Currently, many token-related transactions, such as token listing, minting, burning, etc., can only be proposed by the token owner who can not be changed once the token is issued on Binance Chain.

This BEP proposes the solutions to provide more convenience and flexibility for these transactions.

3. Status

This BEP is already implemented

4. Motivation

To reduce the transaction's dependence on the related token’s owner and make the ownership of token changeable, we introduce those solutions as following:

  • Providing an entrance to transfer the ownership of a specific token.
  • Removing the owner verification when handling some token related transactions.

5. Specification

5.1 Transfer Ownership

TransferOwnership transaction can transfer ownership of a specific token to another address, and only the original owner has the permission to send this transaction.

A fee (a fixed amount of BNB) will be charged on TransferOwnership transactions.

Parameters for TransferOwnership Operation:

Field Type Description
From string the address who wants to transfer the ownership to another address
Symbol string the token symbol needs to be transferred ownership
NewOwner string the address who is assigned to be the new owner of the token

5.2 Token Owner Verification Changes

Currently, some token-related transactions are restricted to being proposed by token owners while others are not. After the implementation of this BEP, any address can burn its own tokens. Here is the comparison below:

Transaction Type Verify Owner(Before) Verify Owner(After)
list token yes yes
mint token yes yes
burn token yes no
freeze token no no
set URI yes yes
atomic swap related no no
time lock no no
time unlock no no
time relock no no
transfer no no
cross transfer out no no
cross bind yes yes
cross unbind yes yes
