The deal, in plain language.

The mesh is live and under active development. Availability, latency, which models are served, and the feature set can change or break at any time. The service is provided "as is" and "as available," without warranties of any kind. Don't rely on it for anything safety-, finance-, legal-, or health-critical.

Senda serves open-weight models. Their outputs can be inaccurate, incomplete, or offensive, and do not constitute professional advice. You're responsible for reviewing and how you use anything the models generate.

You agree not to use Senda to:

• break the law or generate content that is illegal where you are;
• attack, overload, or disrupt the mesh, the entry node, or any peer — including attempts to de-anonymize peers or users;
• generate content that exploits or harms minors, or that facilitates serious harm to people;
• misrepresent the source of a model's output or circumvent the verification and routing controls.

The paid API preview lets you top up a prepaid API balance in USDC on Solana and spend it on /v1 inference. Free web chat remains free. The preview is experimental: rates, models, availability, and settlement timing can change. Prepaid balance is a service credit for inference — not an investment, deposit account, or crypto token issued by Senda.

You are responsible for sending the correct asset (USDC) on Solana mainnet to the published treasury address. Wrong-chain or wrong-token transfers may be unrecoverable. Deposit attribution depends on network confirmation and our indexing process. Settlement today uses a custodial USDC rail (hot float + Redis balances); an on-chain escrow vault is not the customer path yet.

You may request a refund of unused prepaid API balance (subject to a minimum threshold shown on /buy). Refunds return USDC to a Solana wallet you control. During preview, queued refunds may be processed automatically under shared daily spend caps and kill switches, or by ops if automation is paused — they are not instant and not SLA-backed. Amounts already spent on completed or in-flight inference are not refundable. We may refuse or delay refunds that look abusive, erroneous, or legally restricted.

Contributors accumulate contribution credits for completion tokens served to the mesh. Those credits remain illustrative during early access — they are not cash, not a financial instrument, and not a crypto token, and carry no guarantee of monetary value.

Separately, when a peer serves a paid /v1 mesh request, we may accrue a peer USD liability payable in USDC. Peer payouts are a preview capability: bind a wallet in the desktop app, withdraw at or above the published minimum (see /earn), and expect automated settlement under caps when enabled. Thresholds, timing, tax/KYC requirements, and availability can change. There is no guarantee of payout on any schedule, and automation can be paused. Public aggregates appear on /metrics.

Running a node is voluntary and at your own risk. You are responsible for your own hardware, electricity, network, and for complying with the laws that apply to you — including any tax reporting if you later receive payouts. By serving the mesh you accept that other users' prompts will be processed on your machine to generate responses. You can stop serving at any time.

To the maximum extent permitted by law, Senda and its contributors are not liable for any indirect, incidental, or consequential damages, or for any loss arising from your use of the service, the mesh, model outputs, or running a node.

We may change, suspend, or discontinue any part of the service, and we may update these terms — the date above reflects the latest version. Continued use after a change means you accept it. Questions: open an issue on GitHub. See also our privacy policy.
