Freelance Web3 development.
A freelance developer for the interface and systems around your on-chain product. dApp frontends, wallet integration and token-gated access, from scope to source handover.

On-chain logic. A usable interface.
For a product with a specific reason to use a wallet or on-chain data. We define the supported networks, contracts and user actions before building the interface.
- Wallet flows
- Connection, account changes and network checks. Authentication is designed separately when the product needs a session.
- On-chain interface
- Reads, transaction preparation and clear pending, confirmed and failed states for the agreed contracts.
- Product integration
- Backend connections, access checks and operational handover around the Web3 functionality.
One defined build. A direct line to your developer.
Bring the part that needs building: a frontend for deployed contracts, a wallet flow inside an existing app, or a product that combines on-chain data with ordinary backend systems. We identify the networks, available interfaces and acceptance checks before estimating the work.
A crypto project's public website may need clear content and links without any wallet connection. An existing dApp may need one broken flow repaired. The scope follows that specific job, with crypto payment terms and source handover agreed separately.
Name the on-chain action.
Reading a token balance, proving control of an address and requesting a transfer are different operations. We separate them in the scope so the interface asks for only the action it actually needs.
The supported networks, contract addresses, wallet environments and data providers must be known. A generic promise to support every chain hides compatibility work that belongs in the estimate.
Connection is not confirmation.
Connecting a wallet does not authenticate every future request. Submitting a transaction does not mean it has completed. We model these states explicitly so the product does not grant access or show success too early.
The user can reject a signature, change accounts or switch networks. The interface should explain the current state and give a useful next step. Server-side access checks are required when a wallet controls access to private resources.
Agree the security boundary.
A Web3 interface is not a smart-contract audit. If the project depends on new or modified contracts, contract development and independent review need their own scope and responsibilities.
We also agree what the application stores, which providers it depends on and how someone operates it after launch. Development is paid in crypto, but that does not mean a conventional website needs Web3 features.
A few things to know.
Can you add a wallet connection to an existing website?
Yes, subject to reviewing its architecture and the desired wallet action. We need the target networks, supported wallets and whether the feature requires authentication or transactions.
Does this service include a smart-contract audit?
No. Contract development and independent security review require an explicitly agreed scope. Building an interface should not be presented as proof that the underlying contract is safe.
Can I pay for a normal website in crypto?
Yes. Crypto is how BRÈCHE accepts payment for development. Your project can be a conventional website, application or integration with no blockchain functionality.
