   A gaming platform needs to support three asset types: a single fungible currency, thousands of unique items, and semi-fungible event tickets (each event has multiple identical tickets). They want to minimize gas costs and contract complexity while maintaining interoperability with major marketplaces. Which standard should they choose?

   • AUse ERC-20 for currency and ERC-1155 for items and tickets
   • BUse ERC-721 for everything and treat currency as a special item
   • CUse ERC-1155 for all three asset types
   • DDeploy separate ERC-20 and ERC-721 contracts

   A developer has submitted an EIP that proposes a new precompile for cryptographic operations. The EIP has been in 'Last Call' for two weeks, and no major objections have been raised. However, some core developers are concerned about the security implications. What is the most appropriate next step?

   • AExtend the Last Call period to allow further security review and discussion
   • BWithdraw the EIP because core developers have concerns
   • CImplement the precompile in all Ethereum clients immediately
   • DMove the EIP to 'Final' because the Last Call period has ended without objections
