# Production-minded Web3, not demos

> Clixo builds production-minded Web3 systems — smart contracts, token-gated products, wallet flows, indexers, and dashboards — with security and monitoring planned before launch.

- **Provider:** Clixo — Itasca, IL (hello@clixo.sh)
- **Highlights:**
  - Smart contracts & audits-readiness
  - Token-gated products & wallets
  - Indexers & on-chain dashboards
  - Monitoring & upgrade paths

Most Web3 work breaks in the gap between a clever contract and a product people can actually use. Clixo builds both, with the production discipline on-chain systems demand.

## What we build

Smart contracts, token-gated products, wallet flows, indexers, and on-chain dashboards. We build the contract *and* the experience around it — because users don't interact with bytecode, they interact with your app.

## Security before launch, not after

On-chain mistakes are public and expensive. We plan access control, monitoring, and an upgrade or migration path before anything touches mainnet. Tests model real adversaries, not just the happy path.

## Wallet UX that doesn't lose people

Most "contract bugs" users hit are really wallet-UX bugs — a confusing approval, an unclear signature. We walk the full flow as a first-time user before we call it done.

## Frequently asked

### Do you write and test smart contracts?

Yes — primarily in Solidity. We write adversarial tests for reentrancy, edge cases, and dependency failures, and prepare contracts so an external audit goes smoothly.

### Can you build the app around the contract too?

That's our strength. We handle wallet UX, indexers, dashboards, and the web app — so the on-chain logic and the product around it ship as one coherent system.

### How do you handle security?

Access control, monitoring, and a tested upgrade or migration path are planned before launch — not bolted on after. We treat mainnet as production from day one.
