Blockchain systems
Smart wallets, account abstraction, MPC and zero-knowledge research — products that treat privacy and settlement as first-class design problems.
Software studio · Jerusalem
Instruments for live systems.
Draco Lab builds the tools companies actually run — cryptographic infrastructure, intelligent products, and CRM platforms for financial operations. Research when it is required. Software when it has to ship.
Practice
Four rooms. One lab.
Work moves between protocol, product, and operations. The same team that shipped wallets now designs the systems that sit next to the ledger — CRM, payments, and the intelligence that stitches them together.
Applied AI
Intelligence layered into operational software: routing, classification, and decision support that stays accountable to the people who run the business.
CRM platforms
Customer systems that close the gap between conversations and records — voice, messaging, and collaboration pulled into one operational picture.
Financial operations
Payments, treasury workflows, and regulated product surfaces. Two decades of shipping in financial services, not slideware.
Selected work
Projects in the field.
01
DeFi · ERC-4337
Porta Wallet
A smart wallet and trading surface built on Ethereum account abstraction. Stop-loss, take-profit, and limit flows live inside the wallet — not a separate exchange.
- ERC-4337 smart accounts with programmable transaction flows
- In-wallet trading tools typically reserved for CEX and DEX terminals
- Privacy partnership with COTI V2 for confidential transfers
02
MPC · ZK
Cryptographic Lab
Research and product engineering in multi-party computation and zero-knowledge systems — the original Draco practice, built with cryptographers and protocol engineers.
- MPC and ZK guidance for production-grade protocols
- Architecture for privacy-preserving financial products
- R&D leadership spanning payments and on-chain systems
03
CRM · Communications
Mobile2CRM
A CRM layer that stops treating the phone as a blind spot. Cellular, voice, SMS, WhatsApp, and Microsoft Teams land in the same record the sales team already lives in.
- Conversation capture across mobile and collaboration tools
- Operational visibility for field and remote teams
- Built for revenue organizations that lose context between calls
Studio
A small lab with a long ledger.
Draco Lab is led by Joshua Behar — founder and operator across payments, blockchain, and revenue systems. The work began in cryptographic research (MPC, ZK, protocol design), moved through Porta’s smart-wallet product, and now includes CRM platforms that sit inside the daily motion of a company.
The through-line is financial operations: settlement, trust, conversation, and the software that has to be correct when money moves.
