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.
