Blockchain applied to real business.

Audit-grade smart contracts, real-world asset tokenisation, DApps built for actual end users. We focus on use cases with concrete value: traceability, automatic royalties, programmable contracts, decentralised identity.

SMART CONTRACTS

Logic that runs automatically.

A smart contract is a program living on the blockchain that executes automatically when conditions are met. The rules are written in code and anyone can verify them.

We build in Solidity on EVM (Ethereum, Polygon, Arbitrum, Optimism, Base) following OpenZeppelinbest practices. Test coverage > 95%, fuzzing, slither, pre-deploy audit: aimed at minimising the risk of bugs reaching mainnet.

Automatic escrow — Deposit payments released only on objective conditions. Trustless, programmable, minimal cost.

Perpetual royalties — Artists, creators, IP holders earn their share on every future resale. Code, not promises.

Vesting & governance — Employee/investor tokens with automatic cliff and vesting. On-chain governance with verifiable voting.

TOKENIZATION

Real assets, liquid and traceable.

We tokenize real-world assets (RWA): real estate, artworks, carbon credits, invoices, commodities. Each token represents a share, tradeable, verifiable, traceable to origin.

ERC-20 for fungible tokens, ERC-721/1155 for NFTs and collections, ERC-3643 for regulated security tokens. KYC/AML compliance integrated via on-chain whitelist when the use case requires.

Real estate tokenization — Shares of premium real estate, accessible at 1/100 of the original ticket, tradeable on secondary market.

Transparent carbon credits — Tokenized carbon credits with project traceability: no double-spending, public audit.

Loyalty & membership — NFTs as proof of brand club membership, unlocks exclusive experiences, transferable or not.

WEB3 DAPP

UX that resembles web2.

A well-built DApp should feel close to a modern app: wallet connect in a few clicks, transactions with instant feedback, gas optimisation, account abstraction for onboarding without seed phrases.

Integration with the most-used wallets (MetaMask, WalletConnect, Coinbase, Ledger), multi-chain support, offline mode fallback. UX accessible also to less technical users.

NFT marketplace — Listings, offers, royalty enforcement, semantic search across metadata, attribute filters. E-commerce-grade UX.

DeFi dashboard — Lending, staking, yield: aggregated positions, simulations, liquidation alerts, multi-step transactions.

Decentralized identity — Sign-in with Ethereum, verifiable credentials, soulbound tokens for reputation, user control over data.

AUDIT & SECURITY

Security before on-chain deploy.

There's no rollback on blockchain. A production bug can have serious immediate consequences. So every smart contract goes through: test coverage > 95%, fuzz testing, static analysis (Slither, Mythril), formal verification when the case requires.

Independent audit by specialized partners (CertiK, Trail of Bits, ConsenSys Diligence) before mainnet deploy. Post-launch bug bounty program. Multisig + timelock on critical admin functions.

Code coverage > 95% — Unit, integration, mainnet-fork tests. CI blocking merge under threshold.

Audit & bug bounty — Pre-launch audit + ongoing bug bounty on Immunefi or Hats Finance.

Multisig & timelock — Admin operations require multiple sigs + delay. No 'super user' doing whatever they want.

ENTERPRISE INTEGRATION

Bridge between your business and the on-chain world.

In most cases blockchain doesn't live in isolation: your business systems, ERP, CRM, existing marketplaces need to communicate with on-chain contracts. We build custom indexers (The Graph), oracles to bring in external data (Chainlink, Pyth), webhooks for blockchain events.

Account abstraction (ERC-4337) to pay gas in stablecoin or on behalf of the user, sponsored gasless transactions, social recovery. The end user never sees a seed phrase unless they want to.

Supply chain — Business system events (shipped, received, inspected) on-chain certified with timestamp and signatures. Immutable audit trail.

B2B settlement — Invoices and payments in stablecoin between businesses, with automatic escrow on contractual conditions.

Hybrid Web2/Web3 — Email login + auto-generated wallet, the user adopts blockchain when they want. No traumatic switch.

OFF-CHAIN BRIDGE

VALUE FOR PEOPLE

Blockchain matters when it solves a real problem.

We don't propose blockchain as a marketing posture. If your use case is better solved with a traditional database, we'll say so. Blockchain is useful when a trustless layer really adds value: verifiable transparency, automatic royalties, programmable assets, decentralised identity.

When it does make sense, it enables scenarios that are hard with web2 alone: perpetual royalties, fractional liquid assets, programmable contracts, cryptographic proofs of ownership. The value comes from the logic, not from the token itself.

FREQUENTLY ASKED QUESTIONS

What we get asked the most.

Transparency first. If your question isn't here, write to us: we reply within 24h, from a real person.

Which blockchain should I build on?

Depends on use case. Ethereum mainnet for max security and liquidity (but high costs). Polygon, Arbitrum, Optimism, Base for low cost and speed (L2 with Ethereum security). Solana for extreme throughput. Hyperledger Fabric/Besu for a permissioned enterprise chain. Decided after discovery.

How much does a smart contract cost?

Simple smart contract (base ERC-20 token, NFT collection): €8–15k + audit (€5–15k). Complex smart contract with custom logic: €25–80k + audit. Full DApp with frontend, indexing and integration: €60–250k. Independent professional audits always recommended pre-mainnet.

Is tokenizing real assets legal?

Yes, but regulatory attention matters. Security tokens (representing ownership or investment contracts) are subject to financial regulation (MiCA in EU, Howey test in US). We work with specialized legal advisors and structure issuance compliantly from the start.

What is a smart contract audit?

Security review by independent teams looking for known vulnerabilities (reentrancy, overflow, access control), logic bugs, standard deviations. Cost: €5–50k+ depending on complexity. Time: 1–4 weeks. Always recommended before mainnet deploy with user funds.

Can I integrate blockchain with my existing systems?

Yes. We build middleware that converts your business system events to on-chain transactions (and vice versa), custom indexers to read blockchain state, internal dashboards for the team that doesn't see wallets directly. End user and back-office don't need to know there's blockchain underneath.

How do gas fees work for end users?

With account abstraction (ERC-4337) you can pay gas yourself, charge in stablecoin, or use delegated payments. On L2 (Polygon, Arbitrum, Base) gas is < 1 cent. The user can never even know there's gas: sign up with email, get a wallet, operate normally.
