Your agent's wallet signs

Stokn only hands back an unsigned transaction. We never hold its keys.

What your agent
can call

Not another swap tool. The intelligence: what a token is, what it's worth, and its best version.

best_version("NVDA", amount_usd=1000)

Best-version routing

Every version the caller can hold, fees in. The best comes back unsigned.

fair_value("NVDA")

Off-hours fair value

An estimate of the current price while the market is closed, with a published track record.

token_card("AAPLx")

Token cards

What each token really is: issuer, legal form, custody, dividends and who can buy it.

check_eligibility(version, country)

Eligibility checks

Who can hold what, country by country, before your agent asks for a quote.

Your agent signs. Never us.

We return an unsigned transaction or order payload. The agent's own wallet signs it. We never hold its keys.
