Cost basis andcorporate actions,handled while you hold.
An AI agent for everything that happens after you buy.
Buying is already solved. Everything after it isn't.
Robinhood, Arcus and Rialto handle the buy. tentacle starts one step later.
Robinhood
Arcus
RialtoA wrapper your tax tool doesn't recognize.
Tokenized debt securities, not shares. Crypto tax tools read them as plain ERC-20s and get your basis wrong.
A market that never closes, tracking one that does.
Your tokens trade 24/7. The stock trades NYSE hours. The weekend gap looks like a bug.
Corporate actions with no plumbing yet.
ERC-8056 is a proposal, not an ecosystem. Until it lands, every record date is yours to track.
Five moments in a year of holding.
Each one is a module. None of them asks you what to buy.
You bought across four pools and eleven dates. Now reconcile it.
Every trade across every pool, reconciled into one running figure that fits the debt-security wrapper.

You picked the schedule. tentacle keeps it.
An amount, a token, a cadence — run on a session key scoped to that schedule and nothing else.

Ask why, in your own words.
Ask in plain language, get plain language back. Try it — it runs on the same mock portfolio.
tentacle executes, explains, and shows you risk. It never tells you what to buy.
A deliberate limit, not a missing feature. Picking assets for you is investment advice, and regulated as such.
- NVDA38%
- SPY26%
- AAPL23%
- TSLA13%
- 01
You choose the assets. Every time.
Never suggests a token, ranks one above another, or builds you a portfolio.
- 02
The risk dashboard reports. It doesn't recommend.
Facts about what you already hold. No buy or sell buttons anywhere near the analytics.
- 03
Tax figures are data preparation, not tax advice.
A report you or your accountant can work from. It doesn't tell you how to file.
One dashboard, and a chat that can act inside it.
Cost basis, dividends, risk and Guard alerts in one place — with a chat on top of the same data that can change a setting for you.
Guard alerts and corporate actions reach you on Telegram or email — nothing waits for you to open a tab.
Free to watch. Paid when something gets done. Cheaper if you hold.
No subscription. TENT discounts what you pay — it doesn't unlock it.
- Cost basis
- Guard alerts
- Risk dashboard
- Explanations
- The annual report
- A complex corporate action
- A broker-style spread on Auto-Invest
A token that discounts. Not one that unlocks.
- Not a key
- Nothing sits behind it.
- Not revenue
- A discount, not a claim.
- Not a lock-up
- No staking, no unbonding.
List price. Everything still works.
From your balance. Never moved.
Bigger holding, bigger cut — to a cap.
Priority. Never exclusivity.
On the sources the indexer trusts.
Corporate action data your dapp can read directly.
The indexer behind Corporate Actions, available to any wallet or dapp on Robinhood Chain.
Structured events
type, amount, record and payment date per token.
Verifiable proof
off-chain source plus the on-chain publication, so you can re-check instead of trusting us.
Upcoming actions
ex-dividend and split dates ahead of the date, not after.
Webhooks
subscribe per token, get pushed on publication. No polling.
Computed entitlements
the amount owed to a wallet, already calculated.
A verified indexer of the issuer’s published actions — not the issuer, and no guarantee of payment.
What tentacle can touch, and what it can't.
Read-only by default.
History and balances. No permission to move funds.
Auto-Invest runs on a scoped session key.
One key, one schedule. Revoke it in one action.
Guard sits at your wallet.
Alerts on what you're about to sign, with the reason spelled out.
Right now, everything here is a prototype on mock data.
No on-chain reads, no swaps, no payouts — until it's audited.
Open it and click through a year of holding.
The demo runs a full mock portfolio — a tax year of trades, a dividend paid, a schedule running, an approval blocked. Nothing connects to a wallet, and nothing asks you to sign.
