# All Your Base bags > NFT bags on Base. Each bag owns its own wallet (ERC-6551). What that wallet holds, in dollars, sets the bag's mask: > one of seven levels. The bag's character, traits and aura are drawn and shown from the chain. Facts for AI agents and tools. Everything here can be read from public chain data; nothing needs a key. - Network: Base (chain id 8453). Collection: `0xB0f3dCAF6BE094559213089BD14299f5103cF964` (ERC-721). - Each bag has its own wallet: `accountOf(tokenId)` on the collection. Tokens sent to that address belong to the bag. - The mask is the wallet's counted value: Iron under $20, Onyx from $20, Gold from $100, Magma from $500, Ice from $2,500, Cosmic from $10,000, Diamond from $50,000. It moves at once when the value moves. - What counts: USDC, ETH, shares of listed USDC vaults, and liquid tokens on Base with a trusted price. A token with no trusted price counts as $0. - The aura's colour shows how long the bag has held its level (Red, then Orange at 7 days, up to Rainbow at 730 days). Its brightness shows dollars swapped inside the bag over the last 30 days. - A holder may appoint one agent address for a bag. The agent can swap inside the bag, and stake or send only if the holder switched those on; sends go only to addresses the holder listed. The appointment stops when the bag changes hands. The holder can end it at any time. - Never share a seed phrase or private key. Nobody from the project asks for one. ## For agents - [Agent guide](https://allyourbase.fun/agent.md): reading a bag, who its agent is, the agent rules, payments to a bag - [Indexer API](https://nft-api.allyourbase.fun/): read-only JSON; `GET /` lists every endpoint - [A bag](https://nft-api.allyourbase.fun/bags/1): holder, wallet, mask, aura, the agent that can act right now - [A bag's agent](https://nft-api.allyourbase.fun/bags/1/agent): the current holder's appointment, its limits, what it did ## The project - [Site](https://allyourbase.fun/): mint, your bags, stats - [About](https://allyourbase.fun/#/about): how bags, masks and auras work - [Contracts on Basescan](https://basescan.org/address/0xB0f3dCAF6BE094559213089BD14299f5103cF964) - [Collection on OpenSea](https://opensea.io/collection/all-your-base-bag) ## Optional - [Bag pictures and metadata](https://nft-img.allyourbase.fun/metadata/1): the token metadata a marketplace reads
