This analysis is grounded in first-party technical artifacts originating from the platform itself:
Earlier contextual notes we discussed (e.g., social/WHOIS chatter) are kept to a minimum; the core of this review is the code and the live network traffic produced by the application itself.
The running app is a single-page application (SPA) with a broad feature surface:
The SPA is built with Vue + component libraries (you’ll see Element/Ant patterns in the DOM), and a canvas-based K-line chart renders OHLC candles and volume.
On boot, the SPA fetches a remote JSON configuration that declares:
A representative API line returned by this config is:
https://epi.nz558.com
The front end then binds all REST calls under a common prefix:
/forerest
and proceeds to query:
POST /forerest/kline/find),/forerest/spots/...),/forerest/second/...),Why this matters: the app does not directly call Binance/OKX/Coinbase/CoinGecko/Chainlink/Pyth from the browser. It gets all market data and executes all orders via its own API line. This is the foundation of the “closed-loop” conclusion later.
The line JSON is hosted on OSS (Aliyun) and can be swapped at will. That enables the operator to:
Operationally, this is a hallmark of systems that want flexible domain usage. On its own, it’s not “proof of wrongdoing,” but in combination with the next sections, it becomes a significant risk indicator.
The SPA includes a K-line helper that posts to /forerest/kline/find:
const BASE = "/forerest";
function getKline(payload) {
return http({
url: `${BASE}/kline/find`,
method: "POST",
data: payload
});
}
Real captured responses for the market list/tickers show payloads like:
{
"code": 200,
"data": [
{
"symbol": "BTC/USDT",
"open": 111502.01,
"close": 111244,
"high": 111583.13,
"low": 111226.87,
"chg": -0.0002,
"klineType": 1
},
{
"symbol": "TRX/USDT",
"open": 0.3442,
"close": 0.3440,
"high": 0.3442,
"low": 0.3440,
"chg": -0.0032,
"klineType": 1
}
]
}
Critical implication: whatever prices you see in the chart come from their server. There is no front-end connection to public exchange feeds. If they choose to differ from public marks, the UI will still display their price.
/forerest/spots/...)All Spot actions in the UI call in-house endpoints:
const SPOTS = "/forerest/spots";
function addOrderSpots(body) {
return http({ url: `${SPOTS}/order/add`, method: "POST", data: body });
}
function getOrderPage(body) {
return http({ url: `${SPOTS}/order/page`, method: "POST", data: body });
}
function cancelOrder(body) {
return http({ url: `${SPOTS}/order/cancel`, method: "POST", data: body });
}
function getSpotsBalance(params) {
return http({ url: `${SPOTS}/wallet/balance`, method: "GET", params });
}
UI forms (as seen in your DOM capture) implement:
What you don’t see: a front-end call sending the order to a public venue. Everything is posted to their /forerest/spots/... endpoints.
/forerest/second/...)The seconds/binary module exposes a complete mini-lifecycle:
const SECONDS = "/forerest/second";
function getCycles() {
return http({ url: `${SECONDS}/cycle/findAll`, method: "GET" });
}
function addSecondsOrder(body) {
return http({ url: `${SECONDS}/order/add`, method: "POST", data: body });
}
function getSecondsOrderPage(body) {
return http({ url: `${SECONDS}/order/findPage`, method: "POST", data: body });
}
Risk characteristics of “Seconds”:
The SPA initializes Socket.IO against the active host. There is no wss://stream.binance.com/... or similar in the front-end. This means:
The UI language is USDT-heavy, yet the front-end lacks:
You do see generic phrases like “Third-party Withdraw”, “USD Withdrawal”, “Withdrawal Fee”, “Binding Withdrawal Address.” But the necessary scaffolding a real on-chain flow uses (TXIDs, chain labels, explorer links) is not present in the UI.
Why this matters: even if payouts occur “behind the scenes,” production UIs typically reserve placeholders for TXID/Explorer so that a user can verify a transfer cryptographically. The absence of these hooks strongly suggests a ledger-only model where credits/debits are updated internally without public proofs.
The current interface uses “Staking” wording, but the codebase still contains a Cloud Mining module with endpoints like:
GET /forerest/cloudmining/confInfoPOST /forerest/cloudmining/order/buyPOST /forerest/cloudmining/findPagePOST /forerest/cloudmining/order/findPagePOST /forerest/cloudmining/income/findPageThis is textbook white-label behavior: toggle product names/skins while keeping the same deposit-driven yield scaffolding. Again, there are no on-chain proof hooks on the front-end to validate “earnings.”
Strings and components indicate:
In regulated contexts, referral tooling is usually ancillary. Here, the referral/agent layer is central, tied to deposits and “activity” modules (lotteries, bonus events). This aligns with high-risk monetization patterns.
The production copy includes an explicit “100% deposit guarantee” and “compliant digital asset trading license.”
Bottom line: a high-impact claim with no discoverable evidence in the product is a major red flag.
Within the production copy, blocks referencing other exchange brands appear. In a properly maintained and regulated production build, unrelated brand copy should never ship. Mixed branding is one of the clearest fingerprints of a recycled/white-label codebase deployed under different skins.
addEventListener("contextmenu", ...) with preventDefault() calls).localhost, generic BaseURL placeholders) appear in a production build.BetButton show through in trading buttons.None of these alone proves fraud; together with the closed data/exec pipeline and the product mix, they depict a stack that does not prioritize transparency.
Your DOM snippet shows:
id="k-line-chart") with layered <canvas> elements,BetButton.This proves that the UI indeed renders a familiar exchange-like surface. Paired with the code and network behavior above, we can say with confidence: the surface is exchange-like, but the data and orders are closed-loop.
All browser-side evidence points to “in-house”:
/forerest/kline/find (their server) for chart data./forerest/spots/... and /forerest/second/... (their server) for placement, listing, and cancellation.Translation: prices and settlements are whatever their backend says. You cannot independently verify a trade/fill/settlement against a public orderbook or a published mark index, especially critical for “Seconds” where a single tick flips the outcome.
POST /forerest/kline/find to the active line host (e.g., https://epi...). You will not see public exchange API calls.Each item would be concerning; together they justify a do-not-deposit stance.
From a technical and risk-control perspective, this platform does not meet the bar for a legitimate exchange:
Final stance: Treat Opalp.com as high-risk / behave-as-scam.
Recommendation: Do not deposit. If already exposed, try a small, immediate withdrawal and insist on TXIDs. Escalate if they cannot or will not provide verifiable on-chain proofs.
