[YoshihitoAso]

Is your feature request related to a problem? Please describe.

• Through various use cases of the ibet token standard, we have identified several areas for functional improvement.
• Based on these findings, we believe it is necessary to update the token standard.
• Specific improvements include:
  • Supporting ERC20-compliant approve/transferFrom to accommodate more flexible settlement needs.
  • Supporting features equivalent to EIP-3009 Transfer with Authorization to enable more flexible wallet configurations.

Describe the solution you'd like

• We propose updating the token standard based on these requirements.
• Specifically, we are considering adding the following features:
  • Support for ERC20-compliant approve/transferFrom
  • Support for features equivalent to EIP-3009 Transfer with Authorization

Additional context

• In addition to the above features, we will continue to consider additional functions and improvements.
• We will also consider a migration plan to minimize the impact on existing token holders and users when updating the token standard.
