Terms of use
Last updated 24 September 2026. By using Sigma you agree to these terms. Please read them — they explain what we do and, just as importantly, what we don't.
1Using the service
You must be at least 18 and legally allowed to use digital-asset services where you live.
Sigma is interface software. It helps you find and sign transactions with third-party protocols from your own wallet. We never take custody of your assets.
2No advice
Nothing on Sigma is investment, tax or legal advice. Prices, returns and yields are shown for information only and may be delayed or wrong.
3Risks you accept
Tokenized assets carry issuer, custody, smart-contract, bridge, liquidity and market risk. Transactions on public blockchains are irreversible.
Stock tokens are issued by third parties who decide who may hold or redeem them. They are not available to US persons.
4Limits of our liability
To the fullest extent allowed by law, Sigma is not liable for losses arising from your use of the service, from third-party protocols, or from events outside our control.
5What you may not do
Don't use Sigma to launder money, evade sanctions, manipulate markets, or break any law. Don't attack, overload or reverse-engineer the service.
6Changes
We may update these terms. The date at the top shows the latest version; continuing to use Sigma means you accept it.
