Rapida · Delivery Service Platform
A high-performance delivery platform with real-time tracking and immersive 3D visualizations.
Waterloo Web3 work is unusually serious because the buyers are unusually technical. Clearpath Robotics-adjacent supply chain teams want auditable provenance, not NFT memes. Manulife Waterloo and Sun Life Waterloo evaluate tokenisation under OSFI B-13 lenses, not crypto-summer enthusiasm. eSentire MDR and OpenText Cybersecurity bring threat-research rigour to every smart contract review. Our services reflect that. We build custody platforms with HSM-backed key management and MPC where appropriate, ERC-20, ERC-721, ERC-1155, and ERC-4626 tokenisation rails for vault and real-world-asset use cases, on-chain identity with Verifiable Credentials and Decentralised Identifiers, layer-2 deployments on Arbitrum, Optimism, Base, Polygon, and zkSync, and quantum-resistant signature schemes (CRYSTALS-Dilithium, CRYSTALS-Kyber, Falcon, SPHINCS+) where ISARA-style post-quantum migration is in scope.
Discovery starts with a regulatory classification workshop covering PIPEDA, Ontario FIPPA where public sector is in scope, OSFI Guideline B-13 for OSFI-regulated financial counterparties, and CRTC obligations if telecommunications carriers are downstream. We define on-chain versus off-chain split explicitly, document every data element against PIPEDA categories, and reject designs that put raw PII on public chains. Build runs in two-week sprints with synchronous EST standups, Foundry or Hardhat test coverage targeting 95 percent on contracts, fuzz testing with Echidna, and static analysis with Slither and Aderyn. Audits are mandatory before mainnet deployment, with Trail of Bits, OpenZeppelin, or ConsenSys Diligence as our default external reviewers depending on contract complexity and timeline. Post-deployment includes a Forta or OpenZeppelin Defender monitoring layer and a documented incident response runbook keyed to OSFI B-13 if banking workloads are in scope.
We evaluate whether blockchain is the right fit, select the optimal chain, define tokenomics, and architect the decentralized system.
Design smart contract architecture, define data structures, and map out contract interactions with detailed technical specifications.
Write and test smart contracts with 100% test coverage. Build the frontend dApp with wallet connection, transaction handling, and blockchain event listeners.
Comprehensive smart contract audit including automated vulnerability scanning, manual code review, and formal verification of critical functions.
Deploy verified contracts to mainnet, configure monitoring, set up multisig governance, and launch with community engagement support.
Smart contracts ship in Solidity 0.8.x or Vyper for EVM chains, with formal verification via Certora when an ERC-4626 vault or governance contract justifies the cost. Frontend stacks run on Next.js with wagmi, viem, and RainbowKit, and account abstraction uses ERC-4337 bundlers (Pimlico, Stackup, Alchemy) where gas sponsorship matters. Custody integrates Fireblocks, Copper, or BitGo for institutional flows and self-custody options via Ledger and Trezor for retail. Layer-2 defaults are Arbitrum, Optimism, Base, Polygon, and zkSync, with Solana, Aptos, and Sui considered when their threading and gas profiles match the use case. Canadian data residency for off-chain state runs on AWS ca-central-1 (Montreal) or northamerica-northeast2 (Toronto) for PIPEDA-aligned PII storage. Post-quantum cryptography work uses NIST PQC standardised algorithms (CRYSTALS-Dilithium, CRYSTALS-Kyber, Falcon, SPHINCS+) with ISARA Catalyst-style hybrid deployment patterns.
