Service · Web3 Wallet & Transaction UX
Web3 frontends users can trust with real money.
In Web3 the frontend is the custody interface: a misleading transaction state or a stale balance doesn’t create a support ticket, it loses someone’s assets. I’ve shipped production Web3 frontends across four products — a multichain wallet extension (CTRL, formerly XDEFI), a cross-chain DEX aggregator (Unizen), a wallet with marketplace features (OneArt), and Uniswap v4 analytics (HookRank) — and I build them the way that class of risk demands.
Sound familiar?
The situations this service exists for.
- ■Your dApp works on the happy path but users get lost the moment a transaction is pending, dropped, or replaced
- ■Wallet connectivity and multi-chain support keep breaking as chains and providers evolve
- ■On-chain data in your UI is stale, inconsistent, or hammering RPC endpoints
- ■You’re building a wallet or extension and need someone who has handled the security boundaries before
Scope
What the work covers.
- ■Wallet browser extensions: architecture, signing flows, provider/page trust boundaries
- ■Transaction UX as explicit state machines: pending, confirming, failed, replaced
- ■Multi-chain wallet connectivity and swap flows across EVM chains
- ■On-chain data layers: providers, subgraphs (The Graph), staleness handling
- ■NFT product flows: minting, marketplaces, metadata
- ■ethers.js / web3.js integration patterns that survive protocol churn
Outcomes
What you end up with.
- ■Transaction flows where users always know what happened to their money
- ■Wallet and extension surfaces built around the trust boundary, not around convenience
- ■An on-chain data layer your UI can rely on without lying to users
Engagement formats
How to buy this.
Technical Strategy Session
60–90 minutes
A paid working session on one defined problem: an architecture choice, an AI feature plan, a performance question, a build-vs-buy call. You bring the context; I bring pattern recognition from 13+ years of shipping in situations like yours.
Start here →Product & Architecture Diagnostic
3–5 days
A focused investigation of one high-impact problem. I read the code, profile the system, interview the people closest to the pain, and separate symptoms from causes.
Start here →Implementation or Rescue Sprint
2–4 weeks, fixed scope
I take hands-on ownership of the most critical part of the work — writing production code, making the blocking decisions, and coordinating with your product, design, and backend people until it ships.
Start here →Web3 contracts
Wallets, swaps, and NFT flows are frontend engineering with money on the line. Across four Web3 products I built the extension surfaces and transaction UX that had to get it right.
Tell me what is blocked, underperforming, or difficult to ship.
I will tell you whether I can help — and what the smallest useful next step would be. If I’m not the right person, I’ll say so.
