In Brief
- Chimpers said its new Adventure Pouches are built on ERC-6551, the token bound account standard.
- The project hasn’t published a mint date, supply, price or chain for the pouches.
- Token bound accounts let an NFT hold assets directly, so a character’s gear would move with it on a sale.
Chimpers said its new Adventure Pouches use ERC-6551, the token bound account standard, in a post on X that showed the items’ contents.
The post is the project’s only public statement on the release. It gave no mint date, no supply figure, no price and no chain. Chimpers didn’t say whether the pouches attach to the original 5,555-piece collection, to one of its later drops, or to both.

What the standard does
ERC-6551, titled “Non-fungible Token Bound Accounts,” was proposed in February 2023 by Jayden Windle, Benny Giang and a group of contributors, several of whom worked on ERC-721 and CryptoKitties.
It assigns each NFT its own smart contract account. Those accounts hold ether, ERC-20s, ERC-721s and ERC-1155s, execute transactions when the NFT’s owner initiates them and keep a transaction history of their own. Sell the parent token and control of the account goes with it.
The registry is a singleton and permissionless. Addresses are derived deterministically through CREATE2 from the tuple of chain ID, token contract and token ID, which means an account can be deployed retroactively against any existing token. That matters for a 2021 collection. Chimpers’ ERC-721 contract at 0x80336ad7a747236ef41f47ed2c7641828a480baa can’t be altered, and the standard doesn’t require altering it.
There are known tradeoffs. Every action through a token bound account carries at least one extra contract call for ownership verification, which adds gas. And transferring an NFT into its own account creates a permanent lock with no recovery path.
Where pouches would fit
Chimpers is a set of 5,555 generative pixel characters on Ethereum. Oliver Timperley, who goes by Timpers, created them in 2021, drawing on anime and retro games. The project pitches the tokens as identity for what it calls the Chimpverse.
It has since added Chimpers Dojo, Chimpers Training, Chimpers Chronicles and Chimpers Cards, the last of these on Base. One Cards release, the Arcadegen Pack, ran to 555 cards across 16 designs and was free to mint for eligible collectors.
An inventory container built on 6551 would give those side collections somewhere to live. A card, a training item or a plush redemption could sit inside the character rather than beside it in a holder’s wallet.
Background
Chimpers has pushed harder into physical goods over the past year. A blind-box plush keychain pre-order sold out at more than 3,000 units, and the team has said a second series of blind-box plushes and a run of lifestyle products are planned for the U.S. this year, alongside pop-ups and licensing deals.
The team has said it held off on licensing deliberately, working on the character brand before putting it on shelves. Nickelodeon is among the brands that engage with its posts.
Chimpers hasn’t opened the pouches to holders. The X post shows what’s inside one.
