What we build
What this service covers, in detail.
dApp interfaces, smart contract integrations, wallet connectivity and on-chain analytics, built with transparency in mind.
- 01
dApp development
Web applications that read from and write to chains, with careful state handling and clear failure messages.
- 02
Smart contract integration
Typed integration with existing, audited contracts, including simulation before any transaction is signed.
- 03
Wallet connectivity
Wallet connection, network switching and signing flows that never take custody of user keys.
- 04
Blockchain analytics
Indexed on-chain data turned into dashboards, alerts and exports for operations and compliance teams.
- 05
Tokenization interfaces
Issuance, holder and transfer interfaces for tokenized assets where the legal structure already exists.
- 06
NFT marketplaces
Listing, minting and discovery interfaces built on established standards and contracts.
- 07
DAO governance
Proposal, voting and treasury views that make governance activity understandable.
- 08
On-chain event monitoring
Reliable listeners and indexers for contract events with replay, reorg handling and alerts.
- 09
Identity and verification
Wallet-based sign-in and verifiable credentials integrated with conventional accounts.
- 10
Web3 payment integrations
Crypto payment acceptance through regulated providers or direct on-chain flows, with reconciliation.
- 11
AI and blockchain
Agents that explain transactions and surface anomalies, with human approval before anything is signed.
Example use cases
Where teams put this to work.
- 01
On-chain activity monitoring
Watch wallets and contracts relevant to your business and alert on defined conditions.
- 02
Tokenized membership or access
Gate content or services with wallet-based ownership checks.
- 03
Transparent supply chain records
Anchor selected events on-chain for tamper-evident audit trails.
- 04
Crypto checkout
Accept crypto payments through a compliant provider and reconcile them with orders.

How it works
The engagement, step by step.
- 1
Scope and risk review
Chains, assets, custody model, legal position and audit requirements.
- 2
Architecture
Decide what is on-chain and off-chain, indexing needs and wallet flows.
- 3
Build and simulate
Develop on test networks and simulate transactions before mainnet.
- 4
Security review
Internal checks plus coordination with an independent auditor where contracts are involved.
- 5
Launch and monitor
Staged release with monitoring for failed transactions and anomalies.
FAQ
Frequently asked questions
Do you audit smart contracts?
No. Audits should be done by an independent specialist firm. We build integrations and can coordinate with your auditor.
Do you hold user funds?
No. Our interfaces connect to the user's own wallet and never hold private keys.
Which chains do you support?
Ethereum-compatible networks are the most common. Others depend on available tooling and project needs.
Projects
Reference projects that show this in practice.
Systems we designed as demonstrations, using sample data. Each has features, architecture and security notes.
