Terms of use

What the interface is

The interface is software that runs in your browser. It builds proofs and transactions for open smart contracts (the pools, router, batch manager, swapper and payout contracts described in the docs) and sends them through independent relayers.

We don’t hold your funds or your keys, can’t move or freeze your notes, and can’t reverse a transaction. The contracts have no owner and no upgrade; nobody, us included, controls them.

Your keys

Your private wallet is a recovery phrase made on your device, or derived from a signature of your browser wallet. You alone are responsible for keeping it safe and backed up. Anyone with it can spend your notes and use your private accounts; without it, nobody can recover them.

Who may use it

You may not use the interface if you are, or act for, a person on a sanctions list maintained by the United States (OFAC), the United Nations, the European Union or the United Kingdom, or if you are in a country or region subject to comprehensive sanctions.

You must also be old enough to agree to these terms where you live, and using the interface must be lawful there.

What you may not do

• Use it to launder money, finance terrorism, evade sanctions, or move the proceeds of any crime.
• Use it to hide funds from a lawful court order or tax obligation.
• Attack, overload or interfere with the interface, the relay, relayers or the contracts.
• Use a private account or the AI and agent apps for anything those services forbid.

Third parties

Parts of what you do run through services we don’t operate. They have their own terms, fees and risks, and may refuse, delay or fail a request.

Relayers, keepers, the OHTTP relay

Run by anyone. They send your transactions and carry your requests.

Across

Bridging between chains.

DEXes and Lido

Swaps between the pools, and wstETH for the staked pool.

NEAR Intents, MAYAChain

Payouts to other chains, and ZEC.

zkAPI, IMD

Private AI, and the agent jobs paid from a private account.

The chains

Ethereum, Arbitrum and Robinhood Chain themselves.

A swap or bridge that doesn’t complete is refunded as the contracts and those services provide, which may cost fees.

Fees

The fees are set out in the docs and shown before you confirm. Protocol fees are paid by the contracts on the spot; relayer and exchange fees go to those who run them.

Operators

If you run a relayer or keeper, you do so on your own behalf. You are responsible for the keys, gas and machine you run it on, and for any obligations that come with operating it where you are. Payouts depend on the contracts and on others’ activity; nothing is guaranteed.

Risks

• Smart contracts, zero-knowledge circuits, bridges and exchanges can have bugs or be attacked; you could lose funds.
• Prices move. A swap may receive less than quoted, down to the least amount you accepted. wstETH can trade below its staked value.
• Privacy depends on others using the pools too, and on how you use them: withdrawing the same amount you deposited, soon after, from the same device, can link the two.
• A disclosure report you share shows what it covers to whoever you give it to.
• Laws on privacy tools differ between countries and may change.

No advice, no warranty

Nothing here is financial, legal or tax advice. The interface is provided “as is” and “as available”, without warranties of any kind. To the fullest extent the law allows, the people who build and publish it are not liable for any loss arising from your use of it, from the contracts, or from any third party.

Changes

We may change these terms; the date at the top says when. Using the interface after a change means you accept it. We may also change or stop providing the interface; the contracts keep working without it.
