Web3 & token products
Contracts, mint/transfer flows, and indexers—with wallet UX that does not lose users on step one.
NASBIX TECHNOLOGIES
Blockchain built for trust models you can explain
Public EVM chains and permissioned networks—smart contracts, indexers, wallet flows, and ops runbooks—with security reviews and audit paths baked into delivery from our Karachi center.
Chain & trust modeling
Smart contract engineering
Indexers & APIs
Named solution architects
Blockchain development
Ledger choice first—then code that matches the risk
Blockchain projects fail when nobody documented who must agree, what happens on chain failure, or how keys are stored. NASBIX starts with the trust model: public EVM deployment, L2, or permissioned fabric/Hyperledger-style networks when consortium rules matter—then builds contracts, backends, and UX your compliance and ops teams can follow.
We deliver for startups and enterprises exploring tokenization, supply-chain attestations, loyalty, and Web3 products—not buzzword decks. Named architects pair contract work with off-chain services: indexers, oracles, custody integrations, and admin tools. Product surfaces can continue with our Web3 product and wallet practice when user experience is the differentiator.
- Explicit on-chain vs off-chain boundaries—cost, privacy, and upgrade strategy documented
- Solidity (EVM) and audit-friendly patterns; Rust/move paths scoped when chain demands it
- Testnets, fork tests, and monitoring before mainnet or production network promotion
- Honest “no blockchain” call when a database and signatures solve the problem cheaper
Who we help
When distributed trust is part of the product—not a sticker
Web3 launches, enterprise pilots, and integration programs—scoped with legal and ops reality in mind.
Enterprise & consortium
Permissioned networks, member onboarding, and APIs business systems already use—see enterprise blockchain.
Integrations & attestations
Proof of origin, credentials, and audit trails where immutability helps—not every field on chain.
What you get
Blockchain capabilities that matter
Scoped to your chain, tokenomics, and regulatory context—not a generic ERC-20 tutorial.
Architecture & chain selection
EVM L1/L2, sidechains, or permissioned ledgers—with TCO, finality, and governance trade-offs written down.
Smart contracts
Tokens, escrows, access control, and upgrades (proxy patterns) when change is expected—see smart contract development.
Indexing & APIs
Event listeners, subgraphs or custom indexers, and REST/GraphQL your web and mobile apps consume.
Wallets & signing
EOA, smart-wallet, and custodial integration patterns with clear key custody boundaries.
Oracles & bridges
External data feeds and cross-chain scope only when threat models and fallbacks are defined.
Ops & observability
Deploy scripts, multisig runbooks, explorer verification, and alerting on anomalous contract events.
Security-first delivery
Depth that survives mainnet—and auditor questions
We design for reentrancy, access control, upgrade admin keys, and oracle manipulation—then leave artifacts third-party auditors and your security team expect.
- Threat modeling on contract roles, pauses, and emergency procedures
- Unit, integration, and fork tests; static analysis in CI where applicable
- Audit preparation packages and remediation sprints after external review
- Key management: HSM, multisig, and separation of deploy vs admin keys
- Compliance-aware scoping—jurisdiction, KYC/AML touchpoints, and data off-chain by default
- Coordination with secure SDLC and penetration testing when required
How we deliver
From use case to live network
Testnet demos stakeholders can trace on explorer—before irreversible mainnet deploys.
- 01 · DiscoverTrust model, actors, assets, compliance constraints, and success metrics—not hype slides.
- 02 · ArchitectChain choice, contract boundaries, indexer design, wallet flows, and upgrade policy.
- 03 · BuildContracts, backends, and integration tests on testnet with security checkpoints each sprint.
- 04 · OperateMainnet or prod network launch, monitoring, runbooks, and optional managed support.
