web3 Engineering: dApps and on-chain systems that hold up in production.

We build the systems around a chain: real-time data and analytics, transaction execution where timing matters, and complete dApps from the contracts to the interface people use. Our main focus is Solana, Ethereum and other EVM-compatible chains.

When we can help

For teams launching a dApp, tracking wallets, tokens or contracts in real time, executing transactions where latency decides the outcome, or moving a working script into a system they can operate. We can adapt to other chains when the project calls for it.

  • Real-time chain data

    The wallets, contracts and events your product depends on, streamed to your backend, alerts or dashboards as they happen. Interrupted feeds, duplicate events and confirmations are handled.

  • Analytics and indexing

    On-chain history you can query, with the analytics and dashboards your team or users need. The data is modelled around the questions you ask of it, not around raw blocks.

  • Transaction execution

    Transactions that land when timing decides the outcome. Latency is measured end to end, and fees, pending transactions and uncertain outcomes are handled before any retry.

  • dApp development

    The whole application, from smart contracts to the indexers and APIs behind them to a frontend with wallet connection and transaction flows. Signing boundaries stay explicit, and it ships with production monitoring.

From first look to handoff

  1. 01

    Define the product

    Tell us the chain, the contracts involved and what the dApp or system has to do. A rough outline is enough; we work out timing and triggers with you.

  2. 02

    Validate on-chain behaviour

    We test the contract calls, data and latency that matter on the real chain first, so you see the risks and timings before committing to the full build.

  3. 03

    Build and integrate

    We build the data flow, execution logic and application together, and test retries and recovery, including transactions with uncertain outcomes.

  4. 04

    Deploy and hand over

    We deploy with monitoring and documentation on how to pause, recover and maintain the system, and agree up front who holds access and owns ongoing changes.
