Web3 founders face a problem that doesn't exist in traditional software: the core product is implemented in immutable smart contracts, security failures are financially catastrophic and public, and investors expect a working on-chain product before committing capital. Xenqube is the development partner for Web3 founders — 51-hour MVP sprint to investor-demo, full protocol builds, token launch infrastructure, and security-first engineering that doesn't treat the audit as an afterthought.
A figma prototype and a whitepaper don't close seed rounds in Web3. Investors expect a working on-chain product they can interact with. The fastest path from idea to investor meeting with something real to show is the 51-hour sprint — scope-locked to the single core mechanic, deployed to testnet, accessible via URL. Anything beyond that is production, not demo.
Smart contract security failures are public, permanent, and expensive. Founders who treat security as a phase after the build is complete discover this at the worst possible moment — at launch, with real user funds at risk. Xenqube treats security as an architecture constraint, not a QA step. Core contracts are audited before mainnet deployment. Period.
Pre-seed founders don't have enterprise budgets. We structure engagements around your funding stage — sprint first, production build scoped and phase-gated to your runway. No six-month all-or-nothing contracts. Each phase produces something deliverable that advances your fundraise, so you always have a product to show that matches your funding stage.
AMM and DEX, lending and borrowing protocols, yield aggregators, liquid staking, structured products, delta-neutral vaults, and derivatives. Full protocol stack from smart contracts through frontend, with tokenomics design, governance contracts, and security audit. Production deployment on Ethereum mainnet, Arbitrum, Optimism, Base, or Solana.
NFT marketplaces, generative PFP collections, gaming asset contracts, dynamic NFTs with on-chain traits, creator royalty infrastructure, fractionalization protocols, and NFT-backed lending. ERC-721, ERC-1155, and ERC-6551 (token-bound accounts) implementations. Metadata standards and IPFS storage.
Real-world asset tokenization for property, trade finance, commodities, and alternative assets. ERC-1400 and ERC-3643 security token implementation. Investor KYC/AML, transfer restrictions, yield distribution, and secondary market infrastructure. For founders building the institutional on-chain layer for traditional asset classes.
On-chain AI agent protocols, autonomous treasury management, AI-assisted governance, policy-bound automation, and agentic workflow infrastructure. Integration with AI inference layers, oracle-fed decision inputs, and policy smart contracts. MCP and EigenLayer integration paths for autonomous agent deployments.
Stablecoin issuance and algorithmic mechanism design, payment rail infrastructure, cross-border remittance protocols, batch payment systems, and treasury management tools. CBDC infrastructure for central bank pilots. Regulatory compliance architecture for EMT and ART issuance under MiCA.
Governance token design and launch, proposal and voting contracts, timelock and executor, multi-sig treasury, delegation mechanics, and community governance tools. Protocol parameter governance for DeFi protocols. DAO tooling for DAOs managing real-world operations, grant programs, or multi-chain protocol governance.
We start with a scope lock call: you explain the product concept, we define the single core mechanic that needs to work to prove it, and we lock scope to exactly that — no more. The sprint runs for 51 hours with daily check-in calls. Output: working contracts on testnet, demo URL, and architecture decision records. You go from idea to investor demo in under three days.
After the sprint, you have an architecture decision record that defines the production build. We scope the production path in phases — each phase producing a deployable increment with defined security gates. Phase 1 is typically core protocol infrastructure (contracts, backend). Phase 2 is compliance layer and production UI. Phase 3 is token launch and governance. You decide how many phases to commit to based on your fundraising progress.
Pre-mainnet security audit of all core contracts. For high-TVL protocols, we recommend a third-party audit firm engagement in addition to our internal review. Audit findings are triaged by severity — critical and high findings are mandatory fix before mainnet deployment. Audit report is included in investor due diligence package and public-ready for community trust-building.
30-day post-launch support window. Monitoring dashboards for protocol health, TVL, and security alerts. Incident response support for any post-launch issues. Protocol upgrade and governance support as the protocol matures. Extended engagement options for ongoing protocol development, new feature builds, and ecosystem integration work.
Token launch is where many Web3 startups make expensive mistakes — poorly designed tokenomics that investors can see through, launch contracts that are exploited, or vesting structures that create cliff-related price crashes. Xenqube handles the full token launch stack:
Supply design, distribution allocation (team, investors, ecosystem, community, treasury), vesting schedules and cliff design, emission model for protocol rewards, utility definition tied to protocol mechanics, and governance rights. Documented design rationale ready for investor and community disclosure.
ERC-20 token contract, vesting and cliff contracts for team and investor allocations, DAO treasury contract, liquidity bootstrapping pool or initial DEX offering contract, airdrop distribution contract, and referral incentive contracts. All contracts audited before TGE.
Governor contract compatible with Compound Governor or OpenZeppelin Governor. Timelock for protocol parameter changes. Delegation setup for liquid democracy models. Off-chain voting integration (Snapshot) where appropriate for cost-effective governance participation before on-chain execution.
The 51-hour sprint delivers a working, deployed Web3 product on testnet in under three days. Scope is locked to the single core mechanic that proves your concept — smart contracts deployed, frontend connected, and a demo URL that investors can interact with. Architecture decision records document every key technical choice for investor due diligence and the production roadmap.
Token economics starts with the product mechanic — what the token needs to do to make the protocol work. We design distribution, vesting, emission models, governance rights, and utility that are defensible to sophisticated investors. Design decisions are documented in architecture decision records as part of the sprint or a separate design engagement before the production build.
Yes. Every production deployment engagement includes a smart contract security audit as a pre-mainnet gate. We do not deploy client contracts to mainnet without a security review. For high-TVL protocols, we recommend an additional third-party audit firm engagement alongside our internal review.
Foundry for Solidity on EVM chains (production-grade with comprehensive test coverage), Anchor for Solana, Next.js and wagmi/viem for Ethereum frontends, and Solana web3.js for Solana. Stack is chosen for production reliability and auditability, not novelty.
Sprint first, then phase-gated production build matching your runway. No six-month all-or-nothing contracts. Each phase produces a deployable increment that advances your fundraise — so you always have something to show that matches your current funding stage. We work around your fundraising timeline, not against it.
Ethereum and EVM-compatible chains (Polygon, Arbitrum, Optimism, Base, BNB Chain, Avalanche), Solana (Rust/Anchor), and NEAR Protocol. Chain selection is based on your target user base, transaction cost requirements, ecosystem network effects, and security needs — documented as an architecture decision in the sprint scope lock.
Tell us your product concept and where you are in your fundraising journey. We will scope the sprint, define the MVP mechanic, and book your slot — you can be on testnet in 51 hours.
