About Spacedev
SpaceDev is a blockchain development company that helps startups and enterprises design, build and scale Web3, AI, web and mobile products. Since 2017, its team of 70+ engineers, designers and product specialists has delivered more than 200 projects from offices in Miami, Montevideo and Buenos Aires, working on schedules aligned with US time zones.
Clients work with SpaceDev in two ways. Product teams hand over a full project, from discovery and UX/UI design to development, launch and ongoing support. Engineering teams add pre-vetted developers, designers and QA specialists to their own squad in under two weeks through IT staff augmentation.
On the blockchain side, SpaceDev writes smart contracts in Solidity, Rust and Move and builds DeFi protocols, dApps, asset tokenization platforms, stablecoins and white-label crypto exchanges on Ethereum, Solana, Hedera, Aptos and other networks. BlockAudit, its security division, reviews smart contracts before they reach mainnet. SpaceDev also builds AI agents, LLM integrations and full-stack web and mobile apps with React, Node.js and React Native.
Clients include Collector Crypt, NDAX, Drata, Rarible and Blockus. SpaceDev is an AWS Select Tier Partner and a Hedera Council Community Partner.

Portfolio
NDAX Canada
SpaceDev put together a small dedicated team: two full-stack developers, a project manager, a QA engineer and a UX/UI designer. The team rebuilt NDAX's web platform in TypeScript and Angular 8, with a Node.js and Express backend and MongoDB, and structured it for a regulated financial environment.
A key part of the work was the integration with AlphaPoint, the exchange engine that connects NDAX to the Canadian banking system. SpaceDev made sure account data and user activity stayed accurate and in sync at every step of a transaction.
For mobile, SpaceDev built a native React Native app for iOS and Android. Users can manage their accounts, buy, sell, trade, stake and track earnings from it. The team designed every screen in Figma and simplified the flows that handle real money, especially verification.
Rarible
SpaceDev's senior Web3 engineers led the rewrite of Rarible's core contracts for each new environment: Rust with Anchor for the Solana Virtual Machine (including Eclipse), Move for Aptos, and deployments on new EVM-compatible chains. SpaceDev designed a burn-and-mint bridge between Ethereum and Solana, built contracts for fully on-chain random card packs with tiered rarity, and added upgradeability patterns and deterministic deployment to the original Solidity contracts. To make adoption easier, SpaceDev shipped SDKs and CLI tools in Rust and TypeScript.
Blockchain for Energy (B4E)
SpaceDev assembled a cross-functional Web3 team with Hedera experience and worked with B4E in weekly iterations, from discovery through architecture to delivery. Using Hedera Guardian, the SpaceDev team set up policies with the rules every token must meet before it is minted, so each credit is tied to verified data. SpaceDev replaced the manual onboarding process with an automated self-service flow and built backend services in Node.js, TypeScript and PostgreSQL that keep token issuance, custody and reporting in sync for everyone involved.
Drata
SpaceDev engineers joined Drata as an extension of its in-house team and worked in Drata's stack: Node.js, NestJS, React, Electron and MySQL. SpaceDev rebuilt the Drata Agent as a cross-platform desktop app that runs quietly in the background, checks system settings and sends verified evidence to Drata's automation engine. In parallel, the SpaceDev team helped design and build the Audit Hub, a workspace that gives auditors permission-based access to exactly the data they need, while granular controls keep everything else private.
Collector Crypt
SpaceDev works inside Collector Crypt's product and engineering team. SpaceDev developed the smart contracts behind the vault-to-marketplace flow, a cross-chain bridge across Solana, Ethereum, Base, Monad and ApeChain, and peer-to-peer swaps so collectors can trade cards directly with each other. The team integrated Privy for embedded wallets and social login, Coinflow for fiat and crypto payments, and grading and vault partners PSA, PWCC and ALT. SpaceDev also built Gacha, a pack-opening game, as a React Native mobile app, and continues to maintain the core platform.
