# Blockchain & Web3 development

On-chain there is no hotfix and no quiet delay, and your community is watching the date you announced. We write, test, and deploy contracts and everything around them: mint sites, staking, presales, dashboards.

## Problems clients bring us

- **The mint date is public.** You announced it to your whole community. There's no moving it, and no room for a contract that isn't ready.
- **One bug costs everything.** On-chain there's no hotfix. A single unchecked function can drain a treasury in minutes, permanently.
- **Everyone claims to know Web3.** You hired a “blockchain dev” and got a copy-pasted contract with someone else's bugs still in it.
- **The last dev held the keys.** Deployer wallets, upgrade authority, the repo, all in the hands of someone who stopped answering.
