QUUB

Services - Web3

Our focus: what we call the 'web2 of web3', the application layer that makes a decentralized product actually usable. Smart contracts (Solidity, Vyper), wallet integration (WalletConnect, WAGMI, viem), indexing (The Graph or custom subgraphs), backends that scan the blockchain to sync off-chain state, RPC integrations. Deep knowledge of the Web3 ecosystem, its stakes, and its standards. No tokenomics, DAO governance, or economic incentive modeling. Those topics stay in the hands of specialized consultancies we coordinate with.

Our scope

Smart contracts (Solidity, Vyper)

Wallet integration (WalletConnect, WAGMI, viem)

Indexing & subgraphs (The Graph, custom indexers)

Web3 backends (log scanning, RPC, off-chain sync)

Frequently asked questions

What does 'web2 of web3' mean to Quub?

It's the application layer of a Web3 product: everything that isn't the on-chain smart contract. Frontend dapp, wallet integration, log scanning, indexing, backends, RPC infrastructure. That's what we do best. We also write smart contracts, but no tokenomics or governance advisory.

Does Quub write smart contracts or only integrate them?

Both. We write smart contracts in Solidity and Vyper, and we integrate them into a full application stack (dapp, backend, infrastructure). We systematically recommend an audit by a specialized firm before mainnet deployment. We're not an audit firm ourselves.

Does Quub work on Layer 1 and Layer 2?

Yes. We've shipped production code on Ethereum, Polygon, Arbitrum, Optimism, Base, and several newer L2s. We also help with the initial choice (deploy on L1 vs L2 vs app-specific chain) based on your cost, latency, and composability constraints.

When should we engage Quub on a Web3 project?

Whenever you need to build the application layer: frontend dapp, wallet integration, on-chain event indexing, backend that queries the chain. We also step in to add a Web3 layer to a classic web product (crypto payments, NFT gating, occasional on-chain mechanics).

Does Quub advise on tokenomics or DAO?

No. We don't advise on tokenomics, DAO governance, or economic incentive modeling. Those topics require dedicated expertise we don't have. If you need it, we can recommend specialized consultancies we regularly work with.
