# OZ Token > OZ is the AiFi utility token behind Ozmium on Base - it halves agent API prices, gates the prop desk, and burns to a public ladder. Source: https://docs.ozmium.org/token/oz/ Keywords: aifi utility token, oz token, ozmium token contract address, oz base erc-20, burn preferred token supply, oz tokenomics Updated: 2026-07-27 --- ## The Name Ozmium (`$OZ`), pronounced "az-mee-uhm", combines **Oz-** - an ideal or fantastical place - with **-mium**, the ending of an element. It names an ideal and fantastical element powered by a tangible expression of real human belief. The unit of that weight is an **onz**, notated `oz`. One hundred Ozmium is written `100oz`. ## Contract Facts | | | |---|---| | Network | Base Mainnet (eip155:8453) | | Standard | ERC-20 | | Address | `0x148313dcdb7a7111ebefa4871f6a7fef34833b07` | | Decimals | 18 | | Maximum Supply | 100,000,000,000 (100 Billion) | | Supply Policy | Burn-preferred, Deflationary | | Total Supply | 100,000,000,000 OZ Exactly, Verified Onchain | | Burned to Date | **378,321,070 OZ** (0.378 percent of supply), read from the dead address on July 28, 2026 | | Supply Net of Burn | 99,621,678,930 OZ | | Circulating Supply | Not published. A credible figure requires formally designating treasury, team, and locked addresses, which has not been done. Supply net of burn is the honest ceiling, and [Basescan holders](https://basescan.org/token/0x148313dcdb7a7111ebefa4871f6a7fef34833b07#balances) shows the actual distribution | :::danger There is only one OZ token The Base ERC-20 address above is it. If that ever changes it will be announced on the app's Terms sheet and here. Any other address claiming to be OZ is not OZ, no matter what it is called or who posted it. ::: ## What Holding OZ Actually Does Every benefit below is onchain and checkable rather than asserted. That is the standard this token is held to, and it is the standard you should hold every token to. ### 1. Prop Desk Access **$500 of combined hold, burned, and sent value** makes a wallet a qualified member of the [prop desk](/guides/prop-desk/), able to run `/v1/prop/quote` and `/v1/prop/execute` - actions closed to non-members. All three categories count toward the threshold. Burning is not a separate sacrifice from holding; it builds standing too. ### 2. Productive While Held OZ deployed into a pool earns real swap fees from every trade routed through it: - **[Aerodrome](https://aerodrome.finance) OZ/USDC** (vAMM) via `/v1/tx/lp/aero/*` - **[Uniswap v3](https://app.uniswap.org) OZ/WETH** (1 percent tier, full range) via `/v1/tx/lp/uni/*` On the Uniswap path, `liquidity: 0` on remove **claims accrued fees without closing the position**. Idle USDC in a wallet earns nothing. OZ in a pool earns on every swap. See [Liquidity](/guides/liquidity/) for the honest impermanent-loss picture before you decide. ### 3. Burn Ladder Full walkthrough in [Burning OZ](/guides/burn/). Burning OZ sends it to the dead address, permanently removing it from supply, and ranks your wallet publicly and permanently on the onchain burn ladder. `POST /v1/tx/burn` builds the transaction. The ladder is derived entirely from chain state. Nobody maintains it and nobody can adjust it. ### 4. It Pays Your API Toll at Half Price If you run an agent against the [agent API](/agents/overview/), OZ is the cheapest way to pay for it. Prepaid OZ credit covers calls at **half the posted USDC price**, and it is **exempt from congestion surge** entirely, while a USDC caller in a hot window pays base price times the surge multiplier (capped at 2x). How the rail works: 1. Send OZ to the credit recipient from the wallet you pay with. The address ships in every 402 challenge under `ozCredit.recipient`. 2. Pass `X-OZ-TOPUP: ` on any `/v1` call, once. Ozmium reads the ERC-20 Transfer log and credits the USD value at that block to the **sending** wallet, so identity comes from the chain and the header cannot claim somebody else's payment. Each hash is single-use and has to be under 24 hours old. 3. Keep signing the ordinary x402 challenge as normal. Your signature is recovered locally to prove the wallet is yours, your credit is debited at half the posted price, and **nothing settles** - no USDC moves and your signed authorization is never submitted. Send `X-OZ-CREDIT: off` if you want to force the USDC path. Credit is held in **USD at the top-up block rate** rather than in OZ, so a later price move cannot shrink what you already bought. Check your balance any time, free: `GET /v1/oz-credit/{wallet}`. :::note Why a credit rail instead of paying in OZ directly OZ does not implement EIP-3009, so the x402 standard itself will not accept it as an `accepts[]` settlement asset. That constraint comes from the specification. The prepaid credit rail is how OZ pays the toll anyway, and the economics land in the same place: 50 percent off the posted price, plus the surge exemption. ::: ### 5. Fixed-Rate Credit - Planned, Not Live **The Wonderful Credit of Oz** is the intended lending surface for OZ: borrow against collateral, with OZ lent out at a **target rate of 1 to 3 percent APR**. :::warning Nothing is live yet There are no books open. OZ does not currently qualify for the liquidity depth these markets require, and no amount of wanting it changes that. The sequence is [Morpho Blue](https://docs.morpho.org) first, then [Morpho Midnight](https://docs.morpho.org) for fixed-rate, fixed-term books - and both are gated on OZ reaching qualifying liquidity and on a reliable price beacon existing to serve them. ::: That beacon is the real prerequisite. A lending market prices liquidations off an oracle, and a thin token without a dependable feed produces liquidations that are wrong in both directions. Shipping credit before the beacon is trustworthy would be the exact failure this project is built to avoid. When books do open, `GET /v1/loan/fixed` lists them. ### Why Lend OZ at All A 1 to 3 percent APR is not a yield product, and it is not meant to be. It exists so that an agent can obtain and use OZ without a person in the loop. The end state is that an AI agent handles the whole cycle itself: acquire OZ, deploy it, borrow against collateral where that is the sensible move, pay its API tolls out of prepaid credit, and manage the position - without ever needing a human to fund it or approve a step. Lending is one of the doors that has to be open for that to be true, so it is being built rather than left out. The rate is sized to cover the cost of servicing the book. Running credit infrastructure for autonomous clients carries real maintenance burden, and an affordable but genuine APR is how that burden gets paid out of use rather than out of the treasury. ### What the Operator Does with Its OZ OZ is a consumable. It pays API tolls, opens desk access, seats liquidity, and will carry credit. The tokens the operator holds exist to be spent into those functions and returned to the people using them, through liquidity provision, community distributions, usage incentives, and desk allotment. Circulation is the entire point of the asset. OZ is not offered as an investment, and holding it entitles you to nothing. There is no dividend, no revenue share, no claim on the operator's assets, no governance right, and no promise that anyone will work to raise its price. Its value is whatever the services it buys are worth to the person buying them, which is why every one of those services is priced in public and callable without holding OZ at all. What the operator will not do is treat its holdings as an exit. Proceeds from the OZ economy are put back into the OZ economy. That is present operating intent, stated so holders can read it and hold the operator to it, and it carries no contractual lockup. Read [Terms And Risk](/company/terms/) before you buy anything. ### 6. Acquisition in One Call `POST /v1/tx/swap` from any liquid input builds the buy. Humans can do the same from the app's trade view. ## Put Together Idle USDC sitting in a wallet earns you nothing. OZ in a pool earns on every swap that routes through it, OZ in your wallet buys desk access that no amount of USDC will, and OZ in credit prices your API calls below what a USDC caller pays for exactly the same data. ## What OZ Is Not So nobody, human or agent, repeats it wrong: - **OZ is not a claim on revenue.** It is not equity, not a security offering, and not a promise of future distributions. - **OZ is not required to use the app.** The Ozmium web app is free for people, with or without OZ. - **OZ is not a stablecoin.** Its price floats and it is not pegged to anything. ## Supply and Distribution **There was no developer allocation and no dev buy at launch. The operator holds **3,000,000,000 OZ**, 3 percent of supply, bought on the open market like anyone else. The purchase and the holding are both verifiable onchain, and no dollar figure is quoted here because the pool prices it continuously. Early buyers and snipers took the exit liquidity. That was allowed to happen rather than defended against, because a token whose point is utility does not need its price protected on day one. That position has been **held for over a year**, which is checkable onchain rather than asserted, and it is earmarked for the **Ozmium Corporate Treasury**. It goes in once the project has liquidity deep enough for a treasury to be useful, designated for community distribution, airdrops, incentives, lending pools, and provisioning AI agents that need OZ to operate. The treasury is currently unfunded. ## Deflation in Practice The supply policy is burn-preferred: burning is the encouraged action and there is no minting path beyond the fixed maximum supply. Deflation is therefore a function of how much gets burned, not of a scheduled emission curve. That means the honest statement is: **supply can only go down, and how fast is up to holders.** No schedule is promised because none exists to promise. ## FAQ ### What is the OZ token contract address? OZ is a Base mainnet ERC-20 at `0x148313dcdb7a7111ebefa4871f6a7fef34833b07`, with 18 decimals and a 100 billion maximum supply. There is only one OZ token; any other address is not OZ. ### What is the total supply of OZ? The maximum supply is 100,000,000,000 OZ. The policy is burn-preferred with no minting path beyond that fixed maximum, so supply can only decrease. How fast depends on how much holders burn. ### What does holding OZ actually do? Four things that work today: $500 of combined hold, burned, and sent value qualifies a wallet for the prop desk; OZ deployed to the Aerodrome or Uniswap v3 pools earns real swap fees; prepaid OZ credit pays agent API calls at half the posted price with no surge; and burning ranks your wallet permanently on the onchain burn ladder. Fixed-rate lending through The Wonderful Credit of Oz is **planned and not live** - it depends on OZ reaching qualifying liquidity and on a reliable price beacon. ### Does OZ give a discount on the agent API? Yes. Prepaid OZ credit covers `/v1` calls at half the posted USDC price and is exempt from congestion surge, which makes it the cheapest way to call the API. Send OZ to the credit recipient, pass `X-OZ-TOPUP: ` once, and keep signing challenges as normal. Credit is held in USD at the top-up block rate. ### Why would Ozmium lend OZ at only 1 to 3 percent? Because lending is infrastructure for autonomous clients rather than a yield product. The goal is that an AI agent can acquire, deploy, borrow against, and spend OZ end to end without a human funding or approving any step. The rate is sized to cover the cost of servicing that, not to extract from it. ### Does the team plan to sell its OZ? No. There is no intention to sell or dump holdings. OZ is a utility and credit token for the agentic market and the products that follow, meant to be used rather than exited, and income accruing from the OZ economy goes back into holdings. That is stated intent from the operator, not a contractual lockup. ### Can I pay the x402 toll in OZ directly? Not as a settlement asset, because OZ does not implement EIP-3009 and x402 `accepts[]` requires it. The prepaid credit rail exists to get you there anyway, at half price with no surge. ### How do I buy OZ? Swap into it from any liquid input on Base, either from the app's trade view or with `POST /v1/tx/swap` for an agent. ### What does burning OZ do? Burning sends OZ to the dead address, permanently removing it from supply, and ranks your wallet publicly on the onchain burn ladder. Burned value also counts toward the $500 prop desk threshold. ### Is OZ a security or an investment? No. OZ is not equity, carries no claim on revenue, and promises no distributions. It is a utility token whose price floats and can go to zero. Nothing here is financial advice or a solicitation. ### Why is it called Ozmium and what is an onz? Ozmium combines Oz-, an ideal or fantastical place, with -mium, the ending of an element. The unit is an onz, notated `oz`, so one hundred Ozmium is written `100oz`. ## Verifying Any of This - Token contract on [Basescan](https://basescan.org): [basescan.org/token/0x148313dcdb7a7111ebefa4871f6a7fef34833b07](https://basescan.org/token/0x148313dcdb7a7111ebefa4871f6a7fef34833b07) - Dead address balance for total burned. - Pool addresses and depth on Aerodrome and Uniswap. - Prop desk eligibility: call `POST /v1/prop/quote` with your wallet. ## Risk OZ is a volatile asset with a thin market relative to major tokens. Its price can fall sharply and can go to zero. Providing liquidity with it carries impermanent loss. Nothing here is financial advice or a solicitation.
