These usually appear when a Web3 idea moves from a prototype or a pitch toward real users and real money.
The idea sounds right, but nobody has compared it with a conventional architecture.
Customers ask to pay, hold or withdraw digital assets inside the app you already have.
A hackathon or in-house demo works on a test network, but not for paying users.
Users want iOS and Android, and the web dApp's wallet flow doesn't carry over.
A custody, wallet or infrastructure vendor you depend on is changing terms or shutting down a product.
Contracts, front end, back end and DevOps sit with one or two people who can't cover it all.
We test whether a blockchain is the right tool, pick the network and architecture, and estimate cost before you commit.
Web and mobile decentralized apps with clear wallet flows, readable transaction states and a back end that keeps up.
Token, payment, escrow and governance logic with tests, upgrade plans and admin controls designed in from the start.
Custodial, non-custodial and embedded wallets, from key management to send, receive and transaction history.
Wallet connection, fiat on- and off-ramps, custody providers, KYC, node providers and indexers connected to your product.
Crypto features for fintech products: balances, transfers, trading screens and reconciliation with your ledger.
Moving contracts, data or users to another network or provider, or modernizing an aging dApp without losing history.
Interfaces that explain signing, fees and confirmations in plain language to people who are new to crypto.
Whatever the use case, the same basics decide whether a dApp is safe to run and easy to use.
Only what needs trustless execution goes on chain
Network chosen for fees, speed and ecosystem
Upgrade, pause and admin rules written down
Token and data models agreed before code
Admin roles split, with multi-signature where it matters
Private keys never in code, logs or chat
Signing requests users can read and verify
Independent audit planned for contracts holding funds
Familiar sign-in options next to wallet connection
Fees and confirmation times shown up front
Clear pending, failed and completed states
Recovery paths for lost access
Indexed events and balances in your own database
Alerts on failed transactions and unusual activity
Reconciliation between chain, ledger and providers
Runbooks for incidents and network outages
You have a token, protocol or dApp idea and need one team for contracts, apps and infrastructure.
You want crypto balances, transfers or stablecoin payments inside an existing regulated product.
You're exploring tokenization, digital assets or on-chain records and need an honest view of cost and value.
You own the client and the design, and need engineers for the blockchain and back-end work behind it.
Discovery, architecture and a cost estimate.
Contracts, web or mobile app and back end.
Wallets, payments or on-ramps.
Hardening, testing and monitoring.
Plan and run a migration.
Engineers who join your roadmap.
We map users, assets and trust assumptions, compare a Web3 design with a conventional one and tell you plainly which fits.
On-chain and off-chain parts, network, wallets, providers and compliance touchpoints documented for you to review.
Contracts, apps and back end built together, with automated tests and demos on test networks every sprint.
Internal review of contracts, keys and signing flows, then an independent audit before contracts hold real funds.
Staged mainnet release, monitoring and alerts, then ongoing work as users, networks and providers change.
Discovery, then a defined build
Fixed price after scoping.
For a clear goal: a dApp, a set of smart contracts, a wallet or a crypto feature in your existing product.
Discovery and architecture up front
Contracts, apps and back end in one team
Tested on test networks before mainnet
Audit preparation and fixes included
Hand-over or ongoing support
Engineers who join your roadmap
Monthly, per engineer or team.
For products where Web3 is a steady stream of work: new features, integrations, upgrades and support.
Engineers matched to your stack
Contract, front-end and back-end skills
Your repositories, keys and processes
Releases with review and monitoring
Scale up or down as plans change
We approach Web3 the way we approach fintech: start from users and money flows, keep the blockchain where it adds value, and connect it carefully to everything around it. On the KickEX mobile crypto exchange, our work covered a multi-currency wallet, real-time trading and withdrawals to external wallets.
We worked on KickEX, a mobile crypto exchange with a multi-currency wallet, real-time trading and withdrawals.
Discovery, design, smart contracts, web and mobile apps, back end and QA in one place.
Payments, wallets and integrations with identity verification providers.
Work can start in about two weeks.
85% of our customers come back with new work.
If a database does the job better, we say so before you spend on a chain.
Contracts, indexers and back end designed as one system.
Key handling, permissions and audits are in the plan, not an afterthought.
Repositories, deployer keys and accounts stay with you.
Our engineers in Poland and Cyprus overlap with part of the US working day.
