About VolumeVein & methodology

Data sources

• DexScreener: pairs, prices, liquidity, volume, FDV, pair age and token logos (memecoin watch, scanner, alert tracker).
• RugCheck (Solana) and GoPlus Security (Ethereum, Base, BSC): automated token-risk flags. The scanner also uses honeypot.is on Ethereum, Base and BSC.
• GeckoTerminal: 15-minute candles used only to reconstruct approximate baselines for alerts from before Oct 16, 2026 (marked "approx.").
• DefiLlama: chain DEX volume and TVL. CoinGecko: major coin prices and AI-agent sector market caps.
• News: RSS feeds from CoinDesk, The Block, Decrypt, Cointelegraph (incl. DeFi/NFT/gaming/memecoin tags), The Defiant, NFT Evening and nft now. Headlines link to the publisher; summaries are short excerpts; images are the publisher's own.
• Relay (relay.link) powers the bridge widget. VolumeVein never holds user funds.

High-risk memecoin watch

Refreshed with every site update. For each chain we take DexScreener pairs and keep tokens that pass all of these: 24h volume at least $10,000, liquidity at least $20,000, pair age at least 1 hour; stablecoins, majors and platform tokens excluded; famous names (e.g. PEPE, TRUMP, BONK) excluded when they appear off their home chain; same-ticker copies collapsed to the most liquid one. The top 4 per chain are ranked by 24h volume × 24h momentum (momentum capped between −90% and +300%).

Each card then gets automated flags: RugCheck risks on Solana; GoPlus checks on Ethereum, Base and BSC (honeypot, mintable, owner can change balances, hidden owner, cannot sell all, blacklist, buy/sell tax above 5%). NEAR, Robinhood Chain and Arc have no automated rug check on this list; their cards say so. The risk label is Extreme if the pair is under 24 hours old, liquidity is under $50,000, or a honeypot / cannot-sell / owner-control flag is present; otherwise Very high. "No flags" is never a safety guarantee.

Hourly alert scanner

An alert-only scanner (no trading, no wallets) runs every hour. It gathers candidates from DexScreener token profiles, boosts and searches on Solana, Base, BSC, Ethereum, NEAR, Robinhood Chain and Arc, keeps the most liquid pair per token, then applies these filters:

All chains: pair age at most 72 hours and 1h buys/sells ratio above 1.1.

Safety gate (token is dropped if it fails): Solana uses RugCheck; a "danger"-level risk, mint or freeze authority, a top-holder share above 30%, a normalised RugCheck score above 50, or RugCheck being unavailable all drop the token. Ethereum, Base and BSC use honeypot.is plus GoPlus; a honeypot, buy or sell tax above 10%, owner-can-change-balance, cannot-sell-all or hidden owner drop the token, and so does having no EVM safety data at all. Robinhood Chain and Arc are not supported by honeypot.is; GoPlus is tried, and if no data comes back the token is kept with a "safety check unavailable" flag, which is why those chains use the stricter liquidity and age minimums above. NEAR has no automated safety check.

Score (used only to rank tokens that passed): (1h volume ÷ liquidity) × 20 + 1h price change (clamped −50% to +300%) ÷ 10 + (buy/sell ratio − 1) × 10 + (5-minute volume × 12 ÷ 1h volume) × 5, minus 5 for non-Solana chains. Volume tiers by 1h volume: $30.00K, $100.00K, $300.00K, $1.00M. Up to 5 new alerts per run; a token is not re-alerted within 24 hours unless it reaches a higher volume tier.

Past-alert tracker

Every alert is re-priced on DexScreener at each site update. Change is price since alert time. Alerts from Oct 16, 2026 onward store real alert-time data; earlier ones use reconstructed baselines marked "approx." (shown as n/a when implausible) and are excluded from statistics. "Likely dead" means liquidity under $1K, FDV under $5K, or down more than 98% from a recorded baseline. Past performance is not predictive.

Alert performance stats

Computed only from alerts with recorded alert-time data (from Oct 16, 2026). Win rate: share of those alerts whose latest re-checked price is above the alert-time price. Average / median return: % price change from alert time to the latest re-check; this is not a trade result and ignores fees, slippage, taxes and whether you could actually sell. Likely dead / delisted rate: share marked "likely dead" or "delisted" (definition above). Windows (24h, 7 days, all time) are by alert time. By-chain rows are all-time.

Charts

Coin sparklines show the last 24 hourly closing prices from GeckoTerminal's free API (Solana, Base, BSC, Ethereum, NEAR pools). Where GeckoTerminal has no data (e.g. Robinhood Chain, Arc) a dashed 3-point line is drawn from DexScreener's 24h and 1h % change; it only shows direction, not the real path. Sidebar chain trends show the last 30 complete days of DEX volume from DefiLlama.

Project risk score

Each review gets a 0–100 score (higher = fewer observed risk factors) and a grade (A ≥80, B ≥65, C ≥50, D ≥35, F <35). It is computed automatically from the facts written in the review; nothing is guessed. Factors and points:

• Team transparency (20): anonymous = 0, publicly identified = 20.
• Contract audit (20): none found = 0, audit listed = 20.
• Liquidity depth (20): under $25K = 0, under $100K = 5, under $500K = 10, under $2M = 15, otherwise 20.
• Valuation vs liquidity (15): FDV ÷ liquidity under 5x = 15, under 10x = 10, under 20x = 5, otherwise 0.
• Admin / upgrade control (15): non-upgradeable contracts = 15, upgradeable = 0.
• Track record (10): X account at least 30 days old at review = 5; live product = +5; key feature not launched = no product points.

Factors the review does not establish are marked "unknown" and removed from the total, so the score is a percentage of the points that could be assessed (shown on each review). A high score is not a safety guarantee or a reason to buy.

Limitations

• Automated flags miss many scams and can be wrong; some chains have no automated check at all.
• Data comes from third-party APIs and can be delayed, incomplete or unavailable.
• Prices on the site are snapshots from the last update, not live quotes.
• News categories are assigned by keyword rules and can be imperfect.

Update schedule

The site rebuilds twice a day at 08:17 and 20:17 (UTC+7). The memecoin scanner runs hourly. The "Last updated" badge on the homepage shows the latest rebuild time.
