Antimatter is wallet-based by design. Here's exactly what that does — and doesn't — mean for your data.
To use Antimatter, you connect a wallet and sign a message to authenticate. We store the wallet address used to sign in, and we associate it with your on-chain activity — rounds joined, results, and claims — so we can show you your own history and stats.
Joining a round requires a short-lived cryptographic authorization from our backend before your transaction reaches the Smart Contract. To issue that authorization, our backend may process standard request metadata — such as your IP address and basic browser/device information — for technical transaction authorization, spam and bot prevention, and to apply any regional access restrictions that need to be enforced before a signature is issued.
We do not collect your name, email address, physical address, or any government-issued identification. There is no account registration and no password.
Every deposit, round result, claim, and refund happens through a smart contract on a public blockchain — that's what makes outcomes independently verifiable rather than something you have to trust us about. That also means this data (your wallet address, the amounts you deposit and win, and the outcome of every round you join) is permanently public and cannot be edited or deleted by us, regardless of anything in this policy.
Because this data lives on a public, immutable ledger rather than in a database we control, rights like the GDPR's 'right to be forgotten' cannot apply to it the way they would to an ordinary off-chain database — there is no request we can process that erases a transaction from the blockchain itself.
After you sign a message to authenticate, we issue short-lived session tokens tied to that signature so you stay signed in without re-signing on every page. These tokens identify your session, not you personally beyond the wallet address you already authenticated with.
We do not currently use third-party advertising trackers or analytics services on the Platform. If that changes, this policy will be updated to name them and explain what they collect before they're enabled.
A few third-party services are load-bearing parts of how Antimatter works on-chain; none of them receive personal information from us beyond what's already public on the blockchain:
Antimatter does not currently perform identity verification of any kind. Your identity on the Platform is your Web3 wallet address and nothing else — we have no name, document, or biometric data to verify against, and no third-party KYC provider is involved in the current version of the Platform. If that ever changes, this policy will be updated to describe what's collected and which provider processes it.
Off-chain, we keep an indexed copy of on-chain activity (deposits, results, claims) so the interface can load quickly rather than querying the blockchain from scratch on every page view. This index mirrors the blockchain; the blockchain itself retains the underlying data permanently and independently of us.
You can stop using Antimatter and disconnect your wallet at any time. Because the platform is non-custodial, there is no 'close my account' step required to get your funds out — any prize or refund you're owed is always claimable directly by your wallet, on your own schedule, for as long as the contract exists.
We may update this policy as the platform evolves. Material changes will be reflected on this page.
