Terms of Service

Obscura is an open-source, non-custodial web interface to the Zama Confidential Token Wrappers Registry on the Ethereum Sepolia test network. It lets you browse registered ERC-20 to ERC-7984 wrapper pairs, wrap and unwrap tokens, transfer confidential tokens, decrypt your own balances, and mint test tokens from a faucet.

The Service operates exclusively on Sepolia, a public Ethereum test network. Every token you can interact with through Obscura, including the mock tokens minted by the faucet, is a test asset with no monetary value. Nothing in the Service is an offer, solicitation, or recommendation to buy or sell any asset, and nothing in it constitutes financial, investment, legal, or tax advice.

Obscura never takes possession of your funds, private keys, or seed phrases. Every transaction is constructed in your browser and signed by your own wallet; nothing can move without your explicit approval in that wallet.

You are solely responsible for securing your wallet and for reviewing every transaction and signature request before approving it. Blockchain transactions are irreversible once confirmed; neither Obscura nor anyone else can undo them.

The Confidential Token Wrappers Registry, the ERC-7984 wrapper contracts, and the mock tokens are deployed and operated by Zama, not by Obscura. Obscura only reads from and helps you write to them. The registry's owner can revoke a wrapper at any time; Obscura surfaces the validity flag and blocks wrapping into revoked wrappers, but has no control over registrations, revocations, upgrades, or any other behavior of those contracts.

Confidential balances are decrypted in your browser through a signed user-decryption request and are never sent to or stored on our servers. Be aware of one deliberate exception in the protocol: finalizing an unwrap requires the unwrap amount to be publicly decrypted. Once that happens, the amount is permanently public on-chain. Starting an unwrap means accepting that disclosure.

The Service depends on infrastructure we do not operate: your wallet and its connection tooling, public RPC endpoints, the Zama relayer and its decryption infrastructure, block explorers, and our hosting providers. Their availability, performance, and conduct are outside our control, and their own terms govern your use of them. The Service may be interrupted, degraded, or discontinued at any time without notice.

You agree not to:

• use the Service for any unlawful purpose;
• attempt to exploit, disrupt, or gain unauthorized access to the Service, its API, or the underlying contracts;
• place abusive load on the faucet, the read API, or the relayer;
• misrepresent the Service, or present test assets as having real value.

Obscura's code is open source under the MIT license and lives on GitHub. Third-party names and marks, including Zama and Ethereum, belong to their respective owners; their use here does not imply endorsement.

The Service is provided "as is" and "as available", without warranties of any kind, express or implied. Fully homomorphic encryption on Ethereum is experimental technology; the protocol, the contracts, and this interface may contain defects. Data shown in the interface (balances, pair lists, activity, statistics) may lag or diverge from on-chain state; the blockchain itself is the only source of truth.

To the maximum extent permitted by law, the authors and contributors of Obscura shall not be liable for any indirect, incidental, special, consequential, or exemplary damages, or for any loss of tokens, data, or goodwill, arising from your use of or inability to use the Service, including losses caused by wallet compromise, contract behavior, relayer downtime, or mistakes in transactions you signed.

We may update these terms from time to time. Changes take effect when posted on this page, with the date above updated accordingly. Continuing to use the Service after a change means you accept the revised terms.

Questions about these terms are best raised as an issue on the GitHub repository. For how we handle data, see the Privacy Policy.
