Rapida · Delivery Service Platform
A high-performance delivery platform with real-time tracking and immersive 3D visualizations.
Vancouver Web3 demand spans regulated infrastructure (CTPs, custodians, MSBs), tokenized real-world assets (TSX Venture mining provenance, Vancouver real estate title rails), Web3 gaming building on the Dapper Labs Flow heritage, and self-sovereign identity work emerging from UBC and SFU research. Codazz delivers smart contract development and audit on Ethereum, Base, Arbitrum, Polygon, Solana, and Flow, custodial and non-custodial wallet engineering, FINTRAC-aligned KYC and travel-rule pipelines with Chainalysis or TRM Labs, BCSC pre-registration undertaking documentation, and on-chain provenance systems for the mining and resource clients that anchor the TSX Venture Exchange. Every smart contract engagement ships with a peer audit, formal verification where economic exposure warrants it, and an incident response runbook tied to the realities of irreversible on-chain settlement.
We run discovery, design, build, and deployment on MST hours, which aligns Vancouver legal, compliance, and product calendars in real time instead of through overnight Slack. Discovery opens with a BCSC and CSA regime classification (CTP, restricted dealer, derivatives, security token, utility token), a FINTRAC MSB review if virtual currency is being exchanged or transferred, and a Canadian Securities Administrators Notice 46-307 and 21-332 walk-through if a token is contemplated. Smart contract build sprints are two weeks, with every contract reviewed against the Smart Contract Security Verification Standard (SCSVS) and audited by an independent firm (OpenZeppelin, Trail of Bits, Quantstamp, ConsenSys Diligence) before mainnet. Deployment includes monitoring with Forta or Tenderly, an incident response runbook with multisig and timelock parameters set in calm conditions, and a documented upgrade or migration path your BCSC examiner can follow.
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.
Vancouver Web3 stacks default to Ethereum L1 and L2s (Base, Arbitrum, Optimism, Polygon) for general-purpose deployments, Solana for high-throughput consumer use cases, and Flow for the Dapper Labs gaming and NFT lineage. Custody integrations cover Fireblocks, BitGo, Anchorage Digital, and Copper. Wallet engineering uses WalletConnect, MetaMask SDK, Privy, and Magic for embedded wallets in consumer apps. Compliance tooling layers Chainalysis KYT, TRM Labs, Elliptic, and Notabene for travel-rule data exchange. Infrastructure runs on AWS ca-west-1 (Calgary, launched 2024) and ca-central-1 (Montreal) for Canadian data residency under PIPA and PIPEDA, with cross-region replication where validator or sequencer redundancy matters. Smart contracts are written in Solidity, Vyper, Rust (Solana, Anchor), or Cadence (Flow), tested with Foundry, Hardhat, Anchor, or Flow CLI, and audited before mainnet without exception.
