Solana Memecoin Launch Tracker

Track up to 500 recent Pump-program token creations using raw Solana mainnet transactions and bonding-curve accounts. The Actor decodes Create/CreateV2 instructions, batches curve reads, and computes SOL/USD from the token reserves of a SOL–USDC Raydium pool. It does not call a token-site frontend, market-data aggregator, or off-chain token metadata URI.

Data source and attribution

The source is public Solana on-chain state, read through the RPC endpoint in SOLANA_RPC_URL (Helius RPC in production). Source: Solana mainnet; RPC provided by Helius. The Actor does not resell or expose RPC access. SOLANA_RPC_URL is required; no public-RPC fallback is used. The Actor fetches signature pages until the requested number of creations (capped at 500) or the RPC budget is reached, transactions for uncached signatures, bonding-curve account batches, and SOL/USDC vaults. The named KV cache stores per-mint metadata and recent state. Retained mint entries and observed ATH expire after six hours without observation and retain at most 10,000 mints each; DAS metadata is refreshed after six hours even for a continuously observed mint. Raw holder-account lists are not cached, only derived concentration percentages and their snapshot time. Missing holder/creator/last-trade fields are retried on later runs if an RPC cap interrupted enrichment; populated snapshots are refreshed after five minutes. Every named KV record is trimmed below 8 MB before writing (the platform limit is 9 MB); a cache write failure is logged and does not prevent results or charges. SOLANA_MAX_REQUESTS (default 250) and SOLANA_DAILY_REQUEST_CAP (default 3000 per user) bound RPC calls; this is a fair-share limit, not a key-wide cap. Incremental discovery stops at the first previously indexed signature, and unchanged minute-polls use at most five RPC calls. At the cap, cached rows may be returned free, without a new token-tracked charge. The last good SOL/USD pool quote is reused for at most six hours when the pool read fails or the cap is reached. Individual transaction failures are skipped and HTTP 429 honours Retry-After.

The on-chain instruction supplies mint, name, symbol, metadata URI, creator, curve address and creation time. Supported SOL-paired curves provide real SOL reserves and token-reserve bonding progress. price_sol is the bonding-curve spot ratio of virtual quote to virtual token reserves; price_usd and market cap multiply that ratio by the on-chain SOL/USDC pool rate. These are indicative curve quotes, not executable trade quotes. liquidity_usd values real SOL reserves at that pool rate. Optional DAS getAssetBatch supplies description, image and social links when the RPC provider supports it; no metadata URI is fetched directly. The SOL/USDC pool ratio is indicative, not executable; USDC- and USDT-quoted curves are valued at 1 USD per quote token, using decimals read from each quote mint account and cached across runs. Their price_sol is the USD quote divided by the on-chain SOL/USDC pool rate; real_sol_reserves and SOL-reserve liquidity are null because those reserves are not SOL. PUMP-quoted curves use the on-chain PUMP/USDC PumpSwap vault ratio from a pool verified against the PumpSwap account layout on 2026-10-19. The pool must hold at least $10,000 on its USDC side; its price is read afresh on each run and is indicative, not an executable trade quote. Thin or unavailable pools leave those launches unpriced and free. Other quote mints remain unpriced and free. The run log lists non-SOL quote mint counts; account state can lag during RPC propagation.

Pricing

The current local pay-per-event contract charges $0.001 per Actor start and $0.002 per token-tracked result after the account's one-time allowance of 25 free token results. For example, a first run returning 30 new tokens costs $0.001 + 5 × $0.002 = $0.011, subject to Apify's live active contract and spending limit. Unchanged previously delivered tokens are returned without a second token charge. No prices or billing event names changed in this source migration; check the Store Pricing tab for the live active terms.

Input

limit selects the maximum tokens returned (1–500). maxAgeMinutes, market-cap, liquidity, bonding progress and graduation filters still apply. scanMode=currently_live cannot establish a livestream from on-chain state, so it returns the newest launches and logs a warning; is_currently_live is null. excludeNsfw cannot be verified without off-chain metadata, so unknown NSFW status is not treated as safe or unsafe. Telegram credentials and an ATH threshold remain accepted for compatibility. Observed ATH is accumulated since this Actor first saw each mint, not a lifetime high; it is null on first sighting.

Output limitations

Existing output keys remain present. Values not derivable from the bounded on-chain reads are null, not fabricated: lifetime ATH beyond our observed history, NSFW/ban status, livestream status, replies/participants, sniper activity, creator sell risk, smart-money and viral/copy-trade labels. The last_trade_timestamp is the latest curve-account signature time when available. rug_risk_score_v2 is an on-chain concentration heuristic, not a fraud finding: min(100, 0.5 × top-10-holder % + 0.3 × creator-holding % + 0.1 × (100 − curve-progress %) + 10 if age < 1 hour); the bonding-curve token account is excluded from top-10. Low is <30, medium 30–<60, high ≥60. Missing inputs leave the score and level null. The old rug_risk_score remains null. The pump_fun_url field is retained as a mint-derived link, but the Actor never requests that site. metadata_uri and bonding_curve_address expose the on-chain references without fetching external content. Creator launch counts and graduation history accumulate only from on-chain results delivered since this migration; the old feed-derived history is not reused.

If a curve or pool price is unavailable, dependent numeric fields are null. Discovered mints with a closed, missing, or unsupported curve remain visible with null price fields and no token-tracked charge; missing account state alone does not prove graduation. A decoded curve whose complete flag is set is reported as graduated with 100% bonding progress even if its price is unavailable. The run log counts unavailable valuations by reason. The default minimum market-cap filter is now zero so such launches remain visible; a positive explicit minimum excludes them. Existing saved inputs with a positive market-cap floor may return fewer or no rows. Rug-risk and sniper-activity thresholds reject unknown signals instead of returning unfiltered charged rows. An empty result does not incur a token-tracked charge. The one-time free allowance, unchanged-row deduplication and charged dataset storage are unchanged.
