Blockchain
We build blockchain solutions that bring transparency, security, and efficiency to business processes. From smart contract development to DeFi platforms and NFT marketplaces, our blockchain expertise helps organizations leverage distributed ledger technology for real-world use cases.
What does Masarrati build for blockchain?
Masarrati builds blockchain and Web3 systems: audited smart contracts in Solidity and Rust, tokenisation platforms for real-world assets, permissioned networks on Hyperledger Fabric, custody and wallet infrastructure, and the indexing and backend layers that make on-chain data usable. Contracts are tested, fuzzed and prepared for independent audit before deployment, and the codebase is handed to your team.
Why This Matters
Deployed contract code is difficult to change and every mistake is public, so the cost of a defect is settled before launch rather than in a patch release. Most incidents trace to unstated assumptions: an invariant nobody wrote down, an access control path left open, an oracle trusted further than it should be. The discipline that matters is specification, adversarial testing and a deployment process with governance attached.
Standards We Build To
- EU Markets in Crypto-Assets Regulation (MiCA)
- Dubai Virtual Assets Regulatory Authority (VARA) rulebooks
- FATF Recommendation 16 travel rule for virtual asset transfers
- Local AML and KYC obligations set by the supervising financial regulator
- ERC token standards including ERC-20, ERC-721 and ERC-3643 for permissioned tokens
- ISO/IEC 27001 and SOC 2 controls for custody and key management
What We Offer
Capabilities
Smart Contract Engineering
Solidity and Rust contracts written against stated invariants, with unit tests, property-based fuzzing in Foundry or Echidna, and gas snapshots enforced in continuous integration.
Asset Tokenisation
Token standards, transfer restrictions and investor whitelists that encode jurisdictional eligibility on chain, with off-chain registries linking each token to its underlying legal instrument.
Permissioned Networks
Hyperledger Fabric or Besu deployments with channel design, membership services, chaincode and endorsement policies for consortia that need shared records without a public ledger.
Custody and Key Management
Multi-signature and MPC wallet architecture with hardware security module backing, withdrawal policies, transaction signing workflows and separation of duties between initiators and approvers.
Indexing and Data Layer
Event indexers, subgraphs and reorganisation-safe ingestion that turn chain events into queryable records, so applications read from an API rather than polling nodes directly.
Compliance Integration
KYC and sanctions screening at onboarding, wallet risk scoring through chain analytics providers, and travel rule messaging wired into transfer flows rather than handled off system.
Where This Gets Used
- Asset manager: a tokenisation platform issuing fractional interests with transfer restrictions and an investor register
- Supply chain consortium: a permissioned ledger recording custody handovers between manufacturers, carriers and customs brokers
- Digital asset business: exchange and custody infrastructure with multi-signature withdrawals and approval workflows
- Protocol team: lending and staking contracts with fuzz-tested invariants and a timelocked upgrade path
- Enterprise loyalty programme: a token ledger where points move between partner brands under agreed settlement rules
How We Deliver
Specification
Invariants, actors and failure modes are written down before contract code, because they define the tests
Chain Selection
Network, cost model and finality requirements chosen against the product rather than defaulting to one ecosystem
Build and Audit
Contracts developed with fuzzing and fork tests, then taken through internal review and an independent external audit
Controlled Deployment
Testnet, staged mainnet release and multi-signature governance, with keys and deployment scripts handed to you

Common Questions
Frequently Asked Questions
What blockchain platforms does Masarrati work with?
Ethereum, Polygon, Solana, Binance Smart Chain, Hyperledger Fabric, Avalanche, and Cosmos. We select the optimal chain based on your requirements for speed, cost, decentralization, and regulatory compliance.
What is tokenization and how can it benefit my business?
Tokenization converts assets (real estate, securities, commodities) into digital tokens on blockchain, enabling fractional ownership, 24/7 trading, automated compliance, and global investor access with lower intermediary costs.
How secure are smart contracts?
Smart contracts are as secure as their code. Masarrati follows secure development practices, uses formal verification tools, conducts internal and third-party audits, and implements upgrade patterns for critical contract changes.
What is DeFi and can you build DeFi protocols?
DeFi (Decentralized Finance) offers financial services without intermediaries — lending, trading, insurance, and yield farming. Masarrati has built production DeFi protocols with millions in total value locked.
How do you handle blockchain regulatory compliance?
Through KYC/AML integration, transaction monitoring, regulatory reporting, jurisdiction-specific rule engines, and working with compliance consultants. Masarrati builds regulation into the architecture from day one.
Do we actually need a blockchain for this, or would a database do?
Often a database is the right answer, and we will say so. Distributed ledgers earn their cost when several parties who do not fully trust each other must share a record no single one controls, or when an asset needs to be transferable without an intermediary. If one organisation owns the data and the process, a well-designed database with append-only audit logging gives the same integrity at lower cost and complexity.
Who holds the private keys and deployment authority after handover?
You do. Deployer accounts, multi-signature signer sets and admin roles are configured under your control before mainnet, and any keys used during development are rotated out at handover. We document the deployment scripts, upgrade procedure and governance timelock so your team can execute changes without us. Where you prefer, signing ceremonies are run by your own custodians with our engineers advising rather than holding key material.
How do you handle gas costs and network fees in the product design?
As a design constraint, not an afterthought. Storage layout, batching and calldata use are optimised where the saving is measurable, and gas snapshots run in continuous integration so a change that raises cost shows up in the pull request. Beyond the contract, we model who pays: meta-transactions and paymasters can absorb fees for end users, and moving high-frequency operations to a layer two network is evaluated during chain selection.
Can you connect on-chain contracts to our existing enterprise systems?
Yes, and integration is where most enterprise blockchain effort actually goes. Chain events are indexed into a queryable store, then exposed through APIs that ERP, CRM or core banking systems consume like any other service. Writes go the other way through a signing service with an approval workflow, so a business system never holds keys directly. Reconciliation reports compare on-chain state against the enterprise record, which is what auditors ask for.
