Raindrop — Self-custodial X Trading Overlay

Raindrop — Self-custodial Trading Overlay for X Raindrop turns your X (Twitter) timeline into a live trading terminal. Detect Solana, Ethereum, and Base tokens, Hyperliquid perps tickers, Jupiter prediction markets, and stock tickers inline on every tweet — then trade in one click from a self-custodial wallet. No copy-pasting addresses, no leaving the page. Your keys stay encrypted in local browser storage. Raindrop never custodies funds, never proxies signed transactions through a server, and never executes remote code. ━━━ Tweet Overlays ━━━ Token Overlay — appears under any tweet mentioning a SOL/ETH/Base contract. Shows price, market cap, 24h change, liquidity, holders, and a Buy/Sell button. Perps Overlay — appears under tweets mentioning a Hyperliquid-listed ticker ($BTC, $HYPE, $SOL, etc.) with size, leverage selector, and long/short buttons. Prediction Market Overlay — detects Jupiter prediction market references and surfaces live YES/NO odds, volume, and resolution date with one-click entry. Stock Ticker Overlay — recognizes equity tickers ($AAPL, $TSLA, $NVDA, $MSTR, etc.) with quote data and chart preview. Matched Post Highlight — the post that triggered the overlay gets a persistent cyan glow around the full card so you never lose context while scrolling. Failure Panel — explains exactly why a swap or order didn't go through (low gas, slippage, no route, rejected agent, etc.) instead of failing silently. ━━━ Tokens (Solana / EVM) ━━━ Multi-chain detection — Solana SPL, Ethereum ERC-20, and Base ERC-20 contracts auto-detected from tweet text and links. Jupiter + 0x routing — best-price swaps via Jupiter (SOL) and 0x (ETH/Base) with configurable slippage and priority fees. Quick Snipe — pre-set size/slippage/priority fee for one-tap buys from any tweet overlay. Risk scoring — Rugcheck + GoPlus checks (honeypot, mint authority, freeze authority, tax, LP lock) run automatically before you trade. Holdings & PnL — live portfolio across all three chains with cost basis and unrealized PnL. Sell from overlay — exit positions directly from the same tweet that surfaced the token. ━━━ Perps (Hyperliquid) ━━━ Agent-key trading — approve a local trading agent once (signed in-browser, never transmitted), trade with no per-order confirmations. Revoke any time. Long/short from any tweet — size and leverage selector inline under any tweet mentioning a HL ticker. Live positions & risk — open positions, PnL, liquidation price, margin usage, free collateral, and warning indicators. Order book + depth heatmap — real-time L2 book and visualized bid/ask walls for the focused market.
