Release Notes

New tool at /vanity to generate custom X1 wallet addresses by prefix, suffix, or contains-pattern. Runs entirely in your browser via Web Workers — keys never leave your device. Multi-threaded with live progress, difficulty estimate, and one-click keypair download.

New tool at /account-closer for cleaning up token accounts. Close empty accounts to reclaim rent, or burn unwanted tokens and NFTs in batch. Handles both Token and Token-2022 programs with prominent warnings on irreversible actions.

New security tool at /token-allowance to scan your wallet for active SPL token delegations and revoke any you no longer need. One-click revoke per delegation, or batch-revoke everything in a single transaction.

New tool at /transaction-decoder — paste any X1 transaction signature and get a human-readable breakdown of every instruction, balance change, and program log. Useful for debugging swaps, transfers, and arbitrary on-chain interactions.

Pair pages now have a wallet filter on the Maker column — paste any base58 address to see only that wallet's trades on the current pair. Great for tracking specific traders without leaving the page.

Validator monitor at /capy-mon now sorts by qualifying status by default and supports starring favorite validators (★) with a Favorites-only filter. Stars persist across sessions.

Pool sync now caches token metadata persistently and skips pools that the real-time pipeline already updated within the last 15 minutes. The full sync cycle now finishes well within budget even when public RPCs are flaky.

Reduced trade-indexer log volume by collapsing per-cycle no-op messages while keeping signal (errors and successful indexing) visible. Easier to spot real issues at a glance.

The WSS listener no longer floods the log with transient ECONNRESET messages — it batches and summarizes them. Heartbeat timestamp now reflects actual signature arrivals rather than the last successful tick, so monitoring tools accurately detect ingestion stalls.

New visitors now see Heikin Ashi candles by default, which smooths out noise and makes trend direction easier to read. Existing chart preferences are preserved.

Safety scoring scans LP holder accounts via an archival RPC, so pools with longer histories now correctly detect partial and full LP burns instead of silently scoring zero.

Deploys no longer drop in-flight requests. The web server now runs under PM2 cluster mode, so new code swaps in via a graceful handoff instead of a hard restart. Real-time trade streams and pending API requests survive the swap cleanly.

API responses now include X-RateLimit-Limit, X-RateLimit-Window, and X-API-Service headers so developers building on our API can see their quota without having to trigger a 429 first. Zero impact on latency — served from a static config table at the edge.

Added automated checks for the SSH tunnel that powers real-time price updates. The 5-minute health cron now verifies the systemd service, all three forwarded ports, and does a live RPC probe. If the tunnel ever silently degrades, we hear about it on Telegram within minutes instead of noticing hours later through indirect symptoms.

Switched SQLite (the small app-metadata DB that holds token profiles, transfer graphs, developer accounts) to WAL mode. Concurrent readers no longer block writes, and cache size was raised from 2 MB to 50 MB. Invisible to users but noticeably snappier on admin paths.

LP add/remove events were silently missing from the default "All Trades" feed on pair pages due to a schema mismatch in the backend query — the call ran ~10 times per minute since launch, always failing quietly and returning empty. LP events now show alongside swaps, correctly labeled and timestamped.

Paid listing approvals now confirm the payment transaction on-chain — verifying the signature exists, wasn't reverted, was sent to the correct fee wallet, and met the tier's required amount. Also guards against a single transaction being used to pay for multiple listings.

Reconfigured the renewal pipeline so future certificate refreshes happen cleanly with no manual intervention.

An axios-based bot hitting a non-existent API endpoint ~8k times a day was being rejected by nginx but still consuming a TLS handshake per request. Blocklist rules are now ordered so the bot is dropped at the kernel level before any TLS work happens.

Uncaught JavaScript errors and unhandled promise rejections in the browser are now reported to our own server-side log (no third-party service, no bundled tracker, nothing that slows page load). Problems that would previously only show up if a user reported them now surface automatically within seconds. Capped per-session to prevent noise, rate-limited per IP.

Many pools were showing truncated mint addresses in place of their actual token names (e.g. "DohWBfvX..." instead of "MIND Token"). Metadata lookups now try multiple RPC endpoints with automatic failover, and a nightly backfill picks up any tokens that missed their initial sync. 84% of tracked tokens now display full names; the rest have no on-chain metadata published.

Trades routed through two pools in a single transaction (multi-hop swaps) were only being recorded against one of the pools. Our cross-check against on-chain data showed this affected roughly 13% of swaps on high-volume pairs. All pools touched by a transaction are now indexed, and 24h volume/transaction counts reflect the full picture.

The safety score on heavily-traded pools was timing out due to the depth of LP holder history that had to be scanned on each request. Added a wall-clock budget to the scan and a short negative-cache on failures to prevent retry storms. Cold-miss response dropped from 30s+ (timeout) to under 5 seconds; cached responses return in ~20ms.

The "Top 10 holders own N% of supply" figure in safety scores was incorrectly including each pool's own liquidity vaults as top holders, inflating concentration to near 100% on many pools. Safety now excludes DEX pool vaults across every pool holding the same token, so the concentration figure reflects actual wallet holdings.

Swap attempts that fail on the DEX side (insufficient balance, invalid slippage, etc.) used to show a generic "Swap preparation failed" message regardless of cause. The specific reason is now passed through, so you see the actual problem immediately.

Pool sync, price polling, trade indexing, wallet lookups, holder queries, and safety scans now fail over automatically across multiple RPC endpoints with health-based routing and small retry backoff. A single slow or failing RPC no longer causes silent data gaps or stalled requests.

The real-time SSE trade feed now caps concurrent connections per IP (default 10). Protects site responsiveness from misbehaving clients without affecting normal multi-tab or multi-pair usage.

New tool at /wallet — paste any address or connect your wallet to view token holdings with live USD values, 24h price changes, and a dust filter. Wallet connect auto-redirects to your portfolio.

Full trade history for any wallet pulled from our indexed database of 423K+ trades. See every swap across all XDEX pools with pair names, prices, and buy/sell breakdowns.

Third tab on the wallet page showing trading activity by pool, co-traders (wallets that trade the same pools ranked by overlap), and direct transfer peers. All queries return in under 1 second.

Holder list cache increased from 60s to 5 minutes. The underlying getProgramAccounts RPC call takes 3-8 seconds — now only the first visitor per token pays that cost.

Removed internal paths from robots.txt, stripped technology fingerprinting headers, and slimmed down public API responses to avoid leaking infrastructure details.

All 8 backend scripts now use a consistent set of benchmarked RPC nodes with the fastest endpoints prioritized. Removed unreliable public RPC from fallback rotation.

Approved profile images for FOREST, PV, and 5 other tokens were stored with a stale CDN domain. Corrected all URLs and flushed cached API responses.

Holder lists now label known addresses — XDEX pool authority, DEX vaults, and burn addresses are tagged with colored badges so you can instantly see how much supply is locked in liquidity pools vs held by wallets.

The volume histogram scale was rendering labels on the price axis, causing stray numbers (like "82.87") to appear on the chart. Volume scale is now hidden — bars still display but won't interfere with price labels.

New real-time trade feed at /terminal showing every XDEX swap as it happens. Features a cypherpunk-styled interface with buy/sell color coding, whale alerts (>$25), top trading pairs, active wallet rankings, and live buy/sell volume ratio — all derived from the Geyser stream with zero additional RPC load.

All backend scripts and the web server now use a private RPC node as the primary endpoint, eliminating rate-limit failures that were causing empty holder data and stale prices during high-traffic periods.

Holder queries were returning empty for every token because the web server was hitting the rate-limited public RPC. Switching to the private validator RPC restored holder data, bubble maps, and safety scores across all 830+ pools.

The /api/stream/trades endpoint now supports a global feed (pool=all) that streams every trade across all pools. Powers the Shadow Feed with no per-pool subscription needed.

The Geyser consumer assumed on-chain vault ordering (token0Vault/token1Vault) matched base/quote token assignment, but XDEX doesn't guarantee this. 527 of 830 pools had swapped vault ordering, causing the Geyser pipeline to write inverted reserves and wildly wrong prices (e.g. a $0.00004 token shown as $3,531). The sync now stores explicit baseVault/quoteVault mappings, and the Geyser consumer uses role-based mapping instead of index-based.

The batch sync had the same vault ordering assumption — it assigned vault balances by index rather than by actual token mint. Reserves are now mapped by verifying each vault's on-chain mint. All 830 pool prices, liquidity, and LP data verified against on-chain within 0.03%.

Pool sync now pre-fetches all vault balances in batches of 100 (17 RPC calls for 830 pools) instead of 830 individual calls. Combined with holder count caching, sync dropped from 20+ minutes (timing out) to ~8 minutes on warm runs.

Pools indexed after their first trades permanently had empty charts because the candle aggregator applied a 48-hour lookback window. New pools with no prior watermark now aggregate all historical swaps on their first run, so charts appear immediately.

User-submitted profile images were being ignored because the API used them as a fallback only. Now the uploaded profile logo takes priority over the default IPFS mint logo.

Screener table headers now show "Txns 24H" and "Vol 24H" instead of ambiguous "Txns" and "Vol".

Prices now update directly from the validator's Geyser plugin instead of polling public RPC. Vault balance changes stream in real-time through an SSH tunnel, giving sub-second price updates with zero RPC load. This eliminates the stale data issues caused by public RPC congestion.

Persistent autossh tunnel to the private validator for RPC, WebSocket, and Geyser relay access. Auto-reconnects on drop, survives reboots via systemd. All ports bound to localhost only.

Added a dynamic sitemap.xml with 820+ URLs (all pool pages), robots.txt with crawl rules, and fixed canonical URLs on pair pages that were incorrectly pointing all 810 pages to the homepage.

Trades now refresh immediately when switching back to the tab instead of waiting up to 60 seconds. Tightened polling intervals and added refetchOnWindowFocus to both trade and pool queries.

The batch sync pipeline hung overnight due to X1 public RPC instability — pool sync timed out 4 times, then the price poller got stuck on an unresponsive RPC call. Killed the stuck process and the Geyser pipeline now provides resilience against future RPC outages.

Pool prices now update within seconds of each trade via the WebSocket pipeline, instead of waiting for the 16-22 minute batch sync cycle. Active pools show live prices on both the screener table and pair detail pages.

Sharing a pair link on Discord, Telegram, or Twitter now shows the token name, current price, 24h change, volume, and liquidity in the preview — instead of the generic site title.

The pair detail sidebar now shows "Updated X ago" with color coding: green (< 5 min), yellow (5-15 min), red (> 15 min). Auto-refreshes every 15 seconds.

Broken pages now show a styled error screen with a retry button instead of white-screening. Invalid URLs and missing pools get dedicated 404 pages with navigation back to the screener.

The approval bot was stuck in a 409-conflict restart loop due to duplicate PM2 daemon processes. Cleaned up zombie daemons, added a singleton guard to prevent duplicates, and increased shutdown timeout for clean Telegram session release.

Blocked a persistent bot hammering a non-existent endpoint (/api/price/xnt) at the nginx level. Reduced API burst allowance from 60 to 20 requests.

New tool at /lp-tool to search any token and see all its pools with prices, reserves, and liquidity. Prices for non-standard pairs (e.g. FOREST/XUNI) are derived by looking up each token's price from their own XNT or USDC pools. Includes a cross-price calculator to compute the correct rate when initializing a new pair.

Pick any two tokens and get the calculated exchange rate routed through shared intermediaries (XNT, USDC, pXNT, rXNT). Shows confidence level based on liquidity depth, with a reserve calculator that tells you exactly how much of each token to deposit.

New /api/token-pools endpoint returns all pools for a token with derived USD prices — even for non-standard pairs where the pipeline shows $0. Paired token prices are looked up from their own pools in the system.

An orphaned Next.js process was holding port 3000, causing every PM2 restart to fail with EADDRINUSE. Added restart_delay and max_restarts to the PM2 config to prevent runaway restart loops.

The scrolling marquee now loops seamlessly without visible jumps or gaps at the wrap point

Price, volume, and trade counts in the sidebar now update instantly as trades stream in — no more waiting for the next poll cycle

Pool stats now refresh 4x more frequently on pair pages, keeping the sidebar in sync with live activity

When the live trade stream (SSE) is connected, redundant API polling backs off from 15s to 60s — reducing server load without affecting data freshness

Switching browser tabs no longer triggers a burst of API requests across all active queries

The scrolling ticker no longer makes its own API call when pool data is already loaded — cuts duplicate requests on the home page

New ruler drawing tool on the chart toolbar lets you measure price distance and percentage change between two points

Trades with the same block timestamp now sort consistently by signature — fixes occasional row-shuffling in the transaction feed

Watchlist stars and badge counts no longer flash incorrectly on first page load

Table header stays visually anchored when scrolling horizontally on small screens

Previously only transferChecked instructions were indexed — plain SPL transfer instructions are now resolved via token balance entries and captured as edges

Mixed transactions containing both a swap and a separate wallet-to-wallet transfer no longer lose the transfer edge

Tokens with no transfers show a clear message distinguishing between "not yet indexed" and "no transfers found (AMM-only activity)"

All transfer index progress reset to re-scan with the new instruction-level filter and plain transfer support

Only re-aggregates candle buckets affected by new swaps instead of the full 48h window — major ClickHouse CPU reduction

Reduced inter-batch sleep from 1s to 250ms with RPC rotation per batch to spread load across endpoints

Signature dedup in the real-time trade queue uses a Set lookup instead of linear array scan

Bot now properly releases the Telegram polling session on shutdown, preventing 409 conflicts on restart

Dead endpoint 51.195.104.145 was still in trade indexer RPC list, causing timeout waste every 5th batch

Safety score now detects LP tokens destroyed via SPL burnChecked instruction, not just tokens sent to burn addresses

Threshold widened from 50% to 80% — early-stage tokens now get partial credit instead of a flat zero

XDEX pool vaults, burn addresses, and system accounts are no longer counted as top holders in the safety score

Token profile images now served from gptree.vip via Cloudflare R2

Scheduled backups had stopped running on cron — restored to clean nightly execution.

Safety score now shows actual burn percentage instead of binary pass/fail — pools with 50-90% LP burned get partial credit

Failed transaction batches now retry on a different RPC instead of silently dropping transfers

Holder bubbles are always visible in X-Ray, even when no wallet-to-wallet transfers exist

Fixed fallback that caused all unindexed tokens to display the same XNT transfer graph

Scans up to 100k signatures per cycle per token, resuming deeper each cycle to reach initial distributions

Archival RPC for signature history, fast validator RPCs for transaction data

High-volume tokens with mostly swap activity are now scanned deeper to find actual transfers
