Blockchain,
engineered for real use.
Smart contracts, tokenisation, custody, DeFi, RWA and enterprise chains, engineered with security, compliance and long-term operability built in, not bolted on.
A complete Web3 practice, engineered end to end.
From strategy through smart contracts, custody, tokenisation, DeFi, enterprise chains, bridges, security, L2, compliance, indexing and Web2 integration.
Blockchain strategy & feasibility
Honest assessment of whether a blockchain is the right substrate, and if so which one, grounded in the business problem, not in the tech.
Smart contract engineering
Solidity, Vyper and Rust contracts written to specifications, tested, formally verified where risk warrants, and audited before mainnet, never after.
Wallets, custody & key management
Custodial, non-custodial and MPC wallets, with HSM, threshold signatures and recovery pathways engineered against real user and operational risk.
Tokenisation & RWA
Real-world asset tokenisation, securities, commodities, real estate, engineered with the legal wrappers, custody and disclosure the regulator will actually accept.
DeFi & on-chain finance
AMMs, lending, staking and structured on-chain products, designed against economic security, MEV realities and honest incentive analysis, not TVL cosplay.
Enterprise & permissioned chains
Hyperledger, Corda, Besu and permissioned EVM networks, for consortia and enterprise workflows where a public chain is genuinely the wrong tool.
Bridges, oracles & interoperability
Cross-chain bridges and oracle integrations engineered with an unusually high bar, because most of the losses in Web3 come through these two seams.
Security & audits
Threat modelling, formal verification, adversary emulation and audit coordination, because a smart contract that isn't audited hasn't shipped, no matter what the runbook says.
Layer-2 & scaling
Optimism, Arbitrum, zkSync, Polygon and app-specific rollups, chosen against your throughput, cost, security and interop needs, not against trend cycles.
Compliance, KYC & travel rule
On-chain compliance, KYC/AML, sanctions screening and travel-rule integration, designed for regulators who read code and lawyers who don't.
Indexing, analytics & operations
Subgraphs, indexers, monitoring and analytics, because 'query mainnet' is not an operational strategy in production.
Web2 integration & UX
Integration with legacy systems, KYC providers, payment rails and traditional UX, because most useful Web3 products span both worlds.
Ask the honest question first.
A delivery model that asks whether a blockchain genuinely fits before designing one, and that treats security and custody as load-bearing engineering.
Frame
Business problem, regulatory posture, user model and threat model mapped. First honest question: does this actually need a blockchain? Sometimes it doesn't.
Prototype
A prototype against real users, on the substrate we've argued for. Economic model, security assumptions and UX validated before production spend.
Productionise
Full engineering, contracts audited, custody engineered, integrations tested, indexers running, compliance in place, before any real value moves through.
Operate
Contracts monitored, keys rotated on schedule, incidents rehearsed, upgrades governed. Web3 operations that don't take this seriously eventually make headlines.
A serious Web3 toolchain.
Chain, VM, tooling and audit partners are chosen against risk, throughput and interop, not against whichever token is trending.

What prospective clients ask us first.
If your question isn't addressed here, please reach us at hello@tekansa.com.
01Does this actually need a blockchain?
Most times, the honest answer is 'no', a well-designed database beats a chain on almost every operational dimension. Blockchain earns its place where you genuinely need multi-party trust without a central custodian, tokenisation of value, censorship resistance, or a public settlement layer. We start every engagement by asking this question, and we're willing to say 'no' when the fit isn't real. That saves clients an expensive detour.
02Which chain, Ethereum, an L2, Solana, or a permissioned network?
Per use case, on evidence. Ethereum L1 for maximum security and composability with the largest ecosystem. L2s (Optimism, Arbitrum, zkSync, Polygon) for cost and throughput on the same security assumptions. Solana where high throughput and low fees dominate. Permissioned chains where the consortium is the whole point and a public chain is genuinely wrong. We choose against user model, transaction volume, cost envelope and regulatory posture, not against ideology.
03How do you approach smart contract security?
As the load-bearing engineering activity, not as a checkbox before mainnet. Threat modelling from day one, extensive unit and property-based testing, static analysis with Slither and Certora, formal verification where risk warrants, and independent audits before any real value moves. Bridges and oracles get extra scrutiny, most of the sector's losses come through those seams. Nothing ships without a monitoring and incident-response plan.
04How do you handle custody, keys and operational security?
Custody model is designed against user risk, operational risk and regulatory posture, custodial with HSMs for institutional flows, MPC for hot signing, non-custodial for user-sovereign products. Key rotation, recovery, quorum and signing policy are engineered before launch, not after. This is the area where inexperienced teams lose funds most often, so we treat it with the same rigour as core banking key management.
05How do you handle compliance, KYC and AML on-chain?
On-chain and off-chain compliance are designed together, KYC providers integrated, sanctions and PEP screening, transaction monitoring, travel-rule integration for CASP flows, and evidence trails that make sense to a supervisor. We keep pace with MiCA, FATF and jurisdiction-specific frameworks. Compliance work is engineered alongside the product, not retrofitted before an audit, otherwise it never fits.
06How do you handle Web2 integration and mainstream UX?
Most useful Web3 products live at the seam with Web2, accounts, KYC, payments, notifications, support. Wallet UX (social recovery, account abstraction, session keys) plus classical Web2 UX plus real customer service is usually what turns a demo into a product. We design that seam deliberately rather than pretending users will happily use a self-hosted node.
