The app
Token
Hold THKR to claim holder vouchers of credit every day and get up to 30% off top-ups, or pay with THKR and get 25% more credit.
THKR is the token of Thinkr on Robinhood Chain. It launched on Pons V2 on 22 October 2026, and its official contract is:
0xbd095fb55F55d59F1e16115dabe3b81D5ce035DcAny token that uses the name Thinkr with another contract is not Thinkr's.
Holder vouchers
Every 1M THKR in your wallet earns one holder voucher a day. A holder voucher starts at $0.40 of credit, and its value can rise with the market. It pays for every model and feature of the app, as the credit of a top-up does: chats in both lanes, images, and video.
| Rule | Value |
|---|---|
| Rate | One holder voucher a day for each 1M THKR |
| Value | From $0.40 of credit |
| Minimum | 100K THKR |
| Count | The lowest balance of your wallet in the last 24 hours |
| Pool | 15% of the creator fees of the day before |
| Claim | At least once every 30 days to keep earning |
| Earned | Stays yours after you sell or move your THKR |
| Lock | None |
Your THKR stays in your own wallet, and you can move it any time. Holder vouchers you have earned stay yours, even after you sell or move your THKR. Parts of a voucher carry over until they make a whole one, so 100K THKR earns one holder voucher every 10 days.
The count takes the lowest balance of your wallet in the last 24 hours. When THKR moves to another wallet, the old wallet stops earning at once and the new one starts 24 hours later, so the same tokens cannot claim twice. Your share follows the THKR you hold: one wallet with 10M THKR earns the same as 10 wallets with 1M each.
All holder vouchers of a day share one pool of credit, worth 15% of the creator fees of THKR from the day before. If the vouchers that holders earn pass it, every share scales down by the same percentage that day.

Claim holder vouchers
Hold THKR
Keep at least 100K THKR in your own wallet on Robinhood Chain for 24 hours.
Sign the claim
Open dash.thinkr.sh and sign a message with your wallet. The claim costs no gas. Claim every day, or let a few days add up and claim them together. Claim at least once every 30 days to keep earning.
A wallet in an app that cannot sign messages claims with a transfer instead. Paste its address on the dashboard. Then send at least 1,000 THKR from that wallet to the claim address that the dashboard names, within one hour. Only that wallet can send the transfer, so it proves the wallet as a signature does. A contract keeps the claim address. Once the claim goes through, the contract burns 1,000 THKR and sends the rest back to your wallet. When the claim does not go through, it sends all of it back. The transfer needs a little ETH for gas.
Your browser blinds the vouchers
Your browser makes the holder vouchers and blinds each one before it goes to Thinkr. Thinkr checks the balance of your wallet and signs the vouchers without seeing them.
Spend them in the chat
Your browser removes the blinding and keeps the signed vouchers with your credit. The app spends them as it spends the vouchers of a top-up.
Why holder vouchers are blind
Holder vouchers use the RSA blind signatures of RFC 9474, as the vouchers of a top-up do (Credit). Thinkr sees which wallet claimed and how many holder vouchers it got. It never sees a voucher before you spend it, so it cannot tell which chats a wallet paid for.
Holder vouchers have a signing key of their own, so Thinkr's proxy can tell a holder voucher from the voucher of a top-up, but not which wallet claimed it. As with a top-up, the time of a claim and of a spend, or your IP address, can still link the two in some cases.
Holder discount
Top-ups cost less while you hold THKR. When you top up in the dashboard, Thinkr reads the THKR of the wallet that pays as the hold counts it, the lowest balance of the last 24 hours, and the highest tier that it reaches sets the discount.
| Hold | Discount on a top-up |
|---|---|
| 100K THKR | 10% |
| 1M THKR | 20% |
| 10M THKR | 30% |
The discount stacks with the bonus of paying with THKR. At 20% off, $5 of credit costs 4 USDG, or $3.20 of THKR. The price at a discount holds for 15 minutes, and only the wallet that asked for it can pay it. Thinkr keeps that price under a hash of the top-up and the wallet, never the address of the wallet.
Pay with THKR
Top up in the dashboard with THKR and get 25% more credit than the same amount in USDG. Credit shows each step.
Burn and buyback
The THKR paid for credit feeds the burn of THKR. Once Thinkr earns revenue, part of it buys THKR back and burns it.
THKR is a utility token. It is not an investment, and nothing in these docs is financial advice.
