PHAZOR –
an enterprise SaaS platform
PHAZOR is an enterprise SaaS platform that allows regulated organizations to deploy and govern multi-signature wallets on a fully private, permissioned EVM-compatible blockchain.
Team task
The goal was to transfer the strict approval requirements typical of the traditional financial environment, several signatures, clearly defined roles, and a complete paper chain, to a private infrastructure with no connection to the public network.

Used Technologies
Solidity powers the smart contracts governing wallets and token operations, drawing on our ERC-20 token development experience, with PostgreSQL handling structured platform data and audit records. Redis drives the background job queue, keeping the interface responsive.

About the client
The company, whose operations are subject to regulation, already had a robust system in place for managing its traditional financial transactions: multi-party approvals, role hierarchies, and audit trails that stand up to scrutiny.
- private blockchain
- real-time transactions
- ERC20 token
Digital assets were a blind spot — each of the available options involved transferring control to a third-party custodian or making transactions public on a public blockchain.

Project overview
Problem
The challenge wasn’t blockchain; it was making one behave like a regulated financial system. Several organizations on one platform, with absolute data isolation, every action logged and tamper-proof for regulators, approval rules that match real hierarchies, and billing transparent enough to skip reconciliation entirely. All while feeling fast, despite blockchain confirmations being inherently slow.
Solution
We deployed a permissioned Hyperledger Besu blockchain with IBFT2 consensus — zero gas fees, 10-second finality, full infrastructure control. Safe protocol powers configurable multi-signature wallets with real-time approval tracking, while two-layer RBAC is enforced at both API and UI levels. Background processing on Bull and Redis keeps the platform responsive while blockchain work completes behind the scenes.
Final result
The client manages digital assets entirely on their own network, with institutional-grade multi-signature governance replacing single-custodian risk. Our private blockchain development made that possible without exposing a single transaction to the public chain. Every action is auditable on demand, turning compliance reviews into a query rather than a scramble. Automated invoicing delivers full cost transparency with zero manual work.
