Decentralized Applications
Blockchain & Web3 Development
Develop blockchain integrations where a shared ledger or wallet-based experience fits the product. We scope network choices, contract behavior and security review requirements before implementation.
Remote delivery for businesses in India and internationally.
Build around the problem you need to solve
A blockchain component should have a clear role in the product, such as shared on-chain state or a wallet-based interaction. IZIES develops smart contracts, decentralized application interfaces and related integrations where those features fit the requirements.
The user experience includes more than a contract call. Network selection, account state, transaction confirmation, failed requests and changes to contract behavior all affect how the application works. Those details belong in the scope from the beginning.
What the work can include
- Smart contract development and automated tests
- Decentralized application interfaces
- Wallet connection and transaction workflows
- Token and on-chain data integrations
- Contract deployment and network integration
- Security review preparation and issue remediation
Example use cases
Wallet-enabled interfaces
Connect a wallet to an application and guide the user through network selection, requested actions and transaction status.
Smart contract workflows
Implement defined on-chain rules with tests for permissions, state transitions and invalid transactions.
On-chain data integrations
Read relevant blockchain events into an application interface or reporting workflow with clear handling of network state.
Technical approach
We define which information belongs on-chain and which should remain in conventional application storage. Contract behavior, permissions and upgrade requirements are documented before deployment. Automated tests and test-network validation cover expected transactions and failure paths. Security review preparation and remediation can be included, while any independent audit must be separately scoped and must not be assumed from development alone.
From requirements to delivery
- 01
Assess the on-chain requirement
Define the purpose, network constraints, actors and data boundaries. Confirm why the feature needs blockchain integration.
- 02
Build and test the interaction
Develop contract logic and interface behavior, including rejected signatures, failed transactions and network changes.
- 03
Prepare review and deployment
Document deployment steps, permissions and operational responsibilities. Address findings from the agreed review process before release.
Common questions
Does every application benefit from blockchain?
No. A conventional database may be more appropriate when the product does not need shared on-chain state or wallet-based interactions. The business requirement should justify the additional complexity.
Is an independent security audit included automatically?
No. Development tests and review preparation are different from an independent audit. If your release requires one, the scope, reviewer and remediation process must be agreed explicitly.
Can you connect a frontend to an existing contract?
Yes. The integration needs the network details, contract interface and expected behavior. The frontend must also handle signing, confirmation and errors so users can understand the status of an action.
