WFN QUICK BRIEF · UNDER 1 MIN
The short version
MODE 2 OF 2
What the primary record establishes
ERC-4494 was created on 25 November 2021. The official specification is marked Stagnant and describes signed approvals for non-fungible tokens. Ethereum — ERC-4494, Stagnant ↗
What the distinction changes
The nonce increases on NFT transfers under the proposed rules. Implementers must reproduce these conditions rather than assume every NFT contract supports the same approval mechanism.
What to check before drawing a conclusion
A wallet should expose contract, network, approved party, token and expiry. A friendly feature name is not a substitute for checking the actual fields being signed.

The linked source supports the documented record; WFN interpretation and illustrative examples are separate.
The proposal describes token-specific approval with a deadline and signature. Its documented status is Stagnant rather than Final.

What the primary record establishes
ERC-4494 was created on 25 November 2021. The official specification is marked Stagnant and describes signed approvals for non-fungible tokens. Ethereum — ERC-4494, Stagnant ↗
The interface uses spender, tokenId, deadline and signature. Unlike an approval for an amount of fungible tokens, it identifies a particular NFT and specifies a nonce for that token. Ethereum — ERC-4494, Stagnant ↗

What the distinction changes
The nonce increases on NFT transfers under the proposed rules. Implementers must reproduce these conditions rather than assume every NFT contract supports the same approval mechanism.
A permit signature authorizes a capability; it does not itself execute a sale. Payment, price and transfer still belong to their respective transactions and conditions.
03 · REVIEW POINTS
What to check before drawing a conclusion
A wallet should expose contract, network, approved party, token and expiry. A friendly feature name is not a substitute for checking the actual fields being signed.
The proposal offers a particular interface, not a general security or adoption guarantee. Record its status and inspect the deployed implementation; the historical specification is not a new protocol launch this week.
