Blockchain & Web3.
Only where a ledger genuinely earns its place.
Drema builds blockchain applications where a distributed ledger solves a real problem — multi-party provenance, tokenised assets, verifiable records — and we say so plainly when a database would serve you better. Most of the engineering in a working Web3 product is off-chain: indexing, wallets, key handling and the interface.
What this sector
actually deals with.
Projects reach for a chain before establishing why. Gas costs make the intended flow uneconomic. Users lose keys and their assets with them. The application depends on public node infrastructure that is slower and less reliable than assumed.
Systems this sector
keeps needing.
The parts of a blockchain & web3 platform that carry the weight. Not everything at once — we build the one that unblocks you first.
Smart contracts
Focused, audited contracts with upgrade paths considered before deployment.
Wallet and key handling
Connection flows and custody choices matched to your users' sophistication.
Chain indexing
Off-chain indexes so the application does not query the chain for every read.
Provenance tracking
Multi-party records where no single participant should own the database.
Tokenisation
Asset representation with the compliance questions addressed first.
Where the work
pays for itself.
The problems blockchain & web3 teams bring us most often. If one of these is costing you money today, it is worth a conversation.
Supply chain provenance
Records shared between parties who do not trust one another's systems.
Verifiable credentials
Certificates and licences a third party can validate independently.
Tokenised assets
Fractional ownership with transfer rules enforced in code.
Loyalty and digital collectibles
Consumer products with genuine transferability.
Not on this list? Sector problems rarely fit a template — tell us yours.
What shapes a build
in this sector.
These are the things a generalist team discovers late and prices badly. We design around them from the first week.
- Immutable deployments — bugs are extremely expensive
- Gas cost as a hard product design constraint
- Evolving and jurisdiction-specific regulation on tokens
- Key loss as an irreversible user outcome

Blockchain & Web3
questions.
Straight answers, including where we are not the right team.
Do we actually need a blockchain?
Often not, and we will tell you. A ledger earns its place when several parties who do not trust each other need a shared record, or when independent verifiability is the product. If one organisation controls the data, a database is cheaper, faster and easier to fix.
How do you handle smart contract security?
Minimal surface area, established patterns over clever ones, comprehensive tests, and third-party audit before mainnet for anything holding value. Deployed contracts are hard to fix, so caution before deployment is the entire strategy.
What about users who lose their keys?
That is the central UX problem in Web3. Depending on your audience we use custodial or smart-account approaches with recovery, rather than assuming mainstream users will manage seed phrases safely. Pretending otherwise loses users and their assets.
Can you build on our chosen chain?
Usually. We work primarily with EVM chains, and we will discuss the tradeoffs of your choice honestly, including cases where a permissioned ledger fits better than a public one.
