In the ERC-721 standard, how is each non-fungible token uniquely identified?

By a unique tokenId within the contract

By a global identifier across all contracts

By a combination of contract address and owner address

A developer wants to propose a new feature that changes how Ethereum nodes validate transactions. They have written a technical specification and are ready to submit it. What is the first formal step in the EIP process?

Present the proposal at an Ethereum developer conference

Deploy a testnet implementation and gather community feedback

Request a core developer call to vote on the proposal

Create a pull request to the ethereum/EIPs repository

A fintech startup is launching a loyalty token that must be transferable between users and integrated with third-party wallets. They plan to follow the most widely adopted standard for fungible tokens. Which interface must their contract implement to ensure compatibility?

ownerOf, safeTransferFrom, tokenURI, and balanceOf

balanceOf, transfer, approve, transferFrom, totalSupply, and allowance

balanceOf, safeTransferFrom, setApprovalForAll, and supportsInterface

What distinguishes an Ethereum Request for Comments (ERC) from an Ethereum Improvement Proposal (EIP)?

ERCs are created by the community, while EIPs are created by the Ethereum Foundation only.

ERCs are application-level standards, while EIPs can include protocol-level changes.

ERCs are only for token standards, while EIPs cover all protocol changes.

ERCs are informal suggestions, while EIPs are legally binding.

In ERC-1155, how are different token types distinguished within the same contract?

By using different contract addresses

By using different owner addresses

By using a unique token ID for each token type

By using different metadata URIs
