In Brief
- According to Chimpers, the project’s newly revealed Adventure Pouches are built on the token bound account standard ERC-6551.
- No mint date, supply, price or chain has been published for the pouches.
- Because token bound accounts allow an NFT to hold assets itself, a character’s gear would travel with it when the token is sold.
In a post on X that offered a look at what the items contain, Chimpers said its new Adventure Pouches are powered by ERC-6551, the token bound account standard.
That post remains the only thing the project has said publicly about the release. It listed no mint date, no supply figure, no price and no chain. Nor did Chimpers clarify whether the pouches are tied to the original 5,555-piece collection, to one of the later drops, or to both.

What the standard does
Carrying the title “Non-fungible Token Bound Accounts,” ERC-6551 was put forward in February 2023 by Jayden Windle, Benny Giang and a group of contributors — several of whom had previously worked on ERC-721 and CryptoKitties.
The standard hands every NFT a smart contract account of its own. Those accounts can hold ether, ERC-20s, ERC-721s and ERC-1155s, they execute transactions at the direction of the NFT’s owner, and they build up a transaction history of their own. Whoever buys the parent token also takes control of the account.
Its registry is both a singleton and permissionless. Account addresses come from a deterministic CREATE2 derivation over the tuple of chain ID, token contract and token ID, so an account can be deployed after the fact against any token that already exists. For a 2021 collection, that detail matters: the Chimpers ERC-721 contract at 0x80336ad7a747236ef41f47ed2c7641828a480baa is immutable, and the standard never asks for it to change.
The tradeoffs are documented. Any action routed through a token bound account requires at least one additional contract call to verify ownership, which pushes gas costs up. Sending an NFT into its own account, meanwhile, locks it permanently with no way to recover it.
Where pouches would fit
Chimpers itself is a collection of 5,555 generative pixel characters living on Ethereum. Oliver Timperley — known as Timpers — created the set in 2021, pulling from anime and retro gaming influences. The project frames the tokens as identity within what it calls the Chimpverse.
Additions since then include Chimpers Dojo, Chimpers Training, Chimpers Chronicles and Chimpers Cards, with the last of those launched on Base. The Arcadegen Pack, one of the Cards releases, totaled 555 cards spanning 16 designs and was free to mint for collectors who qualified.
A 6551-based inventory container would hand those spin-off collections a home. Instead of sitting alongside the character in a holder’s wallet, a card, a training item or a plush redemption could live inside it.
Background
The past year has seen Chimpers lean much further into physical merchandise. Pre-orders for a blind-box plush keychain sold out at over 3,000 units, and the team has said a second blind-box plush series and a line of lifestyle products are slated for the U.S. this year, along with pop-ups and licensing deals.
Holding back on licensing was a deliberate choice, according to the team, which wanted to develop the character brand before taking it to retail. Nickelodeon counts among the brands that interact with its posts.
The pouches have yet to be opened to holders. What the X post provides is a look inside one.
