About Chainsight / Tweet CA Helper

Chainsight builds Tweet CA Helper, a Chrome extension that identifies and validates crypto contract addresses across Solana & EVM networks and surfaces trading signals from third-party data (e.g., DEX aggregators). We’re expanding the product with a cleaner UI, robust data tracking, and advanced features.

The Role

You’ll own major pieces of the Chrome MV3 extension UI, implement client/server analytics, and ship advanced features (pair/contract detection, subscription flows, performance optimizations). You’ll work closely with the founder on a fast feedback loop.

Employment Type: Contract (10–25 hrs/week) with option to extend

Location: Remote (US-friendly hours preferred)

Comp: $20–$30/hr (or fixed-bid per milestone)

What You’ll Do

• UI/UX for MV3 popup & options pages (responsive, fast, consistent design system).
• Data & event tracking: define events, implement tracking (client + server), dashboards, funnels, retention metrics.
• Advanced coding & performance:
• Improve contract/pair detection flows (Solana + EVM) and caching.
• Optimize RPC usage; add retries, timeouts, and fallbacks.
• Background service worker/message-passing architecture for MV3.
• Payments & auth flows (Supabase Auth, subscription checks, edge functions).
• Quality: add unit tests, e2e smoke tests, feature flags, error reporting.
• Security & compliance: privacy-safe event schemas, CSP, secure key handling.

Tech We Use (nice if you know most)

• Chrome Extension MV3, React (for popup/options)
• Node/Express/TypeScript backend (serverless functions ok), Supabase (Postgres, RLS, Auth)
• Web3 basics: Solana RPC, EVM (eth_getCode, etc.), DEX data APIs
• Analytics: PostHog / Plausible / Supabase events (we can align on stack)
• Testing: Vitest/Jest, Playwright
• Tooling: GitHub/Cursor, CI, feature flags, Vercel, Render

Must-Haves

• Experience building Chrome/Edge extensions (MV3 strongly preferred)
• Strong React skills
• Demonstrated event tracking implementation (schema design, client hooks, server ingestion)
• Experience hardening production web apps (performance, errors, logging)
• Clear communication, autonomy, and fast iteration

Nice-to-Haves

• Web3 experience (Solana or EVM RPCs, token/pair concepts)
• Supabase (RLS, SQL policies) and Postgres query tuning
• UI systems, micro-interactions, accessible components
• Prior work with payments/subscriptions
• Data viz (simple dashboards for product metrics)

What Success Looks Like (First 4–6 Weeks)

• Polished MV3 UI shipped (popup + options) with a shared design system.
• Event taxonomy defined and implemented (client + server), basic dashboard live.
• Detection pipeline faster and more reliable (measurable latency/error improvements).
• Error tracking + feature flags in place; CI smoke tests running.
