ERC-6551P Agent-NFT Draft Deploys First on Robinhood Chain Friday

By Elena Vasquez

A draft token standard called ERC-6551P gets its first deployment on Robinhood Chain on Friday, 13 November, with a mint of 6,551 NFTs serving as the test case for a design meant to let AI agents trade from an NFT's own wallet while making the NFT safe to sell. The draft comes from the team behind POLYROB, an open-source agent framework built by The Selfrule Organization. Its founder is Gleb Sychev, former Chief Marketing Officer of 1inch.

The problem ERC-6551P addresses is documented in the ERC-6551 specification itself. Under the original standard, an NFT owns a wallet-like account. A seller can empty that account after a buyer has agreed to pay for the NFT and its contents, leaving the buyer with an empty shell. The ERC-6551 text tells marketplaces to guard against this and states that fraud prevention falls outside its scope. The standard remains in Review status, not Final.

The Ethereum Magicians thread that shaped ERC-6551 between March and April 2023 collected several fixes that were never consolidated: wrapping the NFT, delaying withdrawals, adding a last-transaction timestamp, adding a nonce. ERC-5646 proposed a state fingerprint for related reasons. ERC-6551P pulls those experiments into a single object format.

What does the extension actually guarantee?

The authors rejected the obvious fix, a sale-time lock on the account, on two grounds. A lock stops the agent from working, and it does not revoke an approval already granted. ERC-6551P keeps the account live and makes two narrower promises.

• Nothing survives the sale. After every step of an action, the account re-checks who owns the NFT. If the owner changed, the entire action reverts. The account reads approvals back at the end and reverts if any grew. It never grants NFT approvals, operators or signatures. An action counter lets a sale detect that something happened.
• The buyer gets what was checked. The buyer's conditions are verified after the NFT moves, within the same transaction. If a condition fails, the sale is undone.

Those guarantees hold only on the project's own checked paths: its market, its Seaport zone and its checked fill. A plain marketplace fill checks nothing for the buyer. The draft states this explicitly and lists what it does not cover.

In plain words: the safety claims are path-specific, and an unguarded marketplace fill remains unprotected.

Why a format, and why now?

Agent identity, payments and ownership are currently being built as separate pieces. ERC-6551P attempts to join them. Each mint registers an ERC-8004 agent identity and opens a Uniswap v4 position; the account handles x402 payments and Seaport sales. The team says it compared launchpads, frameworks, wallet kits, ERC-7857 and ERC-8004 and found none that combines account control, transfer-with-sale and a signed action journal.

The timing tracks a wider conversation. On 8 November, Vitalik Buterin argued that ETH is better framed as a store of value than as a fee-burning token, writing that "in the era of AI disruption, stability will be highly valued," as reported by The Block. The POLYROB team applies the same instinct one layer up: if agents hold value, the object holding that value must remain intact through a sale.

The contract kit is open source under an MIT license and intended for any collection. The team plans to take ERC-6551P through the ERC process on the official repository. ERCs are application-layer standards; Final status would mean editors accept the specification, not a protocol change or an endorsement.

What the team admits it does not have

The caveats are material. ERC-6551P is a draft, and only EIP editors can assign it an ERC number. There is no outside audit yet; one is planned, but the contracts cannot be changed after deployment. Trading from these accounts depends on a POLYROB release that, per the project's own site, ships before the mint; the current release can read these accounts but cannot act from them. Every money move defaults to owner approval. A buyer receives the wallet and its contents, not the seller's agent, memory or skills. The offering is not available in the United States, United Kingdom, Canada or Switzerland, and the project states it is not affiliated with Robinhood.

In plain words: the standard's central promise, live agent trading from the NFT account, depends on software that has not shipped.

The timeline

The draft and open contract kit are due on 12 November, when the Ethereum Magicians discussion opens. The allowlist closes the same day at 18:00 UTC. Minting opens on 13 November at 0.033 ETH for allowlisted wallets; the public sale price then falls from 0.099 ETH to 0.033 ETH, with every public buyer paying the final clearing price and the excess refunded.

POLYROB's track record is thin. Its first agent, Rob Ottmachin, began as a Telegram bot in February 2025, went open source in July 2026, and launched a token, PNL, on Pons on 14 September 2026. The project has 1,089 followers on X.

The Ethereum Magicians thread opens on 12 November, and its reception will show whether the proposal survives contact with the editors who decide which drafts earn an ERC number at all.
