Powered by revenue,
not promises.
50,000 diagnostic devices and 5,000 veterinary clinics already generate verified health data. SL adds the economy on top.
SL Watch is a wellness product, not a medical device, and cannot determine the presence of disease.
[01]The Four Minutes
Four minutes. After cardiac arrest, brain damage begins in about four minutes.
And when it happens with no one watching — an elderly parent at dawn, an empty living room in the afternoon — those four minutes are usually empty.
Golden time is decided before the ambulance arrives. So we build the network outside the hospital.
[02]Proof
We only put numbers on the wall that can be verified. Parent-company traction is labeled as parent-company traction.
[03]Business
We put the token on top of a business that already runs without it.
Token capital funds none of the above. $SL works only as a service credit.
“Consumer wearables estimate. ECG measures.”
| Wellness DePIN | SL | |
|---|---|---|
| Sensor grade | consumer PPG | ECG · AUROC 0.88 in clinical research |
| Hardware funding | token / VC capital | manufacturer revenue |
| Data buyer | "someday" | government, today |
[04]The Protocol
One protocol.
Three functions. Four networks.
We don't extract hospital data. Our devices generate it.
[05]Products
Not a portfolio. Four networks on one protocol.
First data buyer in place: government-funded R&D via DIGIRAY
Overview soon[06]Live Apps
Not a roadmap. Apps you can open today.
Real products from the SL ecosystem, already shipping — on the app stores, inside messengers, and on the web.
Measure and track heart rate, blood pressure and ECG with a connected smartwatch — with guardian alerts and reward points.
AI-assisted dental X-ray reads for veterinarians — evidence boxes on every finding, reports in seconds. Operated by DIGIRAY.
The official SL Labs ambassador hub — check-ins, missions and referrals, with live rankings and an opBNB wallet in five languages.
A casual Web3 board game — roll dice, run missions and climb the season ranking. Runs inside LINE with nothing to install.
A first-aid and health quiz game running inside the Toss app — and every answer, right or wrong, comes with an explanation.
HealthFi data is for health management and reference purposes and does not replace medical diagnosis or treatment.
[07]One Credit Economy
Daily reads =
daily demand.
Every AI service across four networks settles in one credit. A day's reads are that day's credit demand — and we publish it on-chain.
[08]Token
The settlement credit for verified health AI.
No re-issuance. No swap. Fixed 2,000,000,000.
$SL will be issued on opBNB, BNB Chain's Layer-2. Sub-cent transaction costs make per-inference settlement practical at scale.
- Quarterly circulation disclosure with third-party verification
- Public cliff & vesting dashboard from TGE
- Smart contracts audited by QuillAudits — all findings resolved · Report ↗
This page is not investment advice. $SL is a functional credit for accessing ecosystem AI services. Digital assets can lose value due to price volatility. Korean residents cannot participate in WCS→SL conversion or token sales.
[09]Research & Validation
We publish our model cards.
A 4-year joint study with Gachon University and Seoul National University Hospital. 204,000+ ECG segments. AUROC 0.88 (clinical research). MFDS (Korea) SaMD certification in progress.
Until certification, we say only "screening support" — never "diagnosis." That discipline is our brand.
SL Watch's wellness features are not a medical device and cannot determine the presence of disease. If an abnormal signal is detected, consult a licensed medical professional. Medical-device functions will be offered after MFDS clearance.
[10]Foundation
We ship discipline before product.
DIGIRAY (manufacturing · gov R&D) ↔ SL Labs Pte. Ltd. (Singapore · token issuance) — funds and data do not cross.
WCS is a non-transferable, non-redeemable contribution score. Conversion is disabled for Korea/US by IP + KYC.
Foundation-operated at launch; opened to external operators from H2 2027.
Fixed 2B · quarterly disclosure · third-party verification · DAXA criteria to be met before any domestic listing.

[11]Roadmap
Roadmap — Proof by Proof
Each stage stands on the last stage's on-chain evidence.
Supply exists: 50,000 scanners, 5,000 clinics, 4-yr research.
First on-chain demand: TGE, VetDental AI live, Watch (wellness), MFDS filing.
Human medicine: AI 0.85+, insurers, MFDS clearance unlocks device functions.
Data-buyer pipeline: insurer → pharma/AI. Node network opens.
Domestic listing: not avoidance, but a prepared listing that first meets DAXA's four criteria and quarterly disclosure.
We're looking for 1,000 First Guardians.
Not airdrop farmers — people who actually wear the device and validate it.
