One Wallet for a Connected Web3 Experience

Managing digital assets across networks means navigating different addresses, fees and transaction flows. Tajir Wallet brings those tasks into a shared mobile experience. Macromodule's contribution focused on connecting wallet functionality, blockchain integrations and product interfaces into a coherent application. The case study shows how multi-chain wallet development brings several engineering disciplines together: network compatibility, data integration, transaction handling and clear interaction design.
Product Challenge and Engineering Response

From Fragmented Workflows to a Unified Wallet

User Challenges

Complexity Across Networks

Different networks introduce different transaction rules. A wallet needs to present those differences clearly without making everyday tasks unnecessarily difficult.
Network-specific addresses and asset standards
Different fee and confirmation models
Separate views for balances, history and portfolio data
Recovery responsibilities that users need to understand
Macromodule's Contribution

A Connected Product Experience

The engineering focus was to connect these activities through consistent interfaces while retaining the information users need for each network and transaction.
A common interface for supported assets and networks
Network-aware transfer and transaction workflows
Connected balance, history and portfolio views
Clearer access to swap and Web3 interactions

Unified Asset Management

Bring supported tokens, balances and activity into one wallet experience with consistent navigation and asset views.

Multi-Chain Compatibility

Accommodate different network requirements while making account selection, transfers and fee information understandable.

Connected Swap Workflows

Connect the wallet interface to swap routes, approvals and transaction progress without requiring users to manage every integration separately.

Self-Custody and Web3 Access

Keep recovery responsibilities clear and support wallet interactions with decentralized applications and compatible hardware devices.

Client Objectives

Tajir Multi-Chain Architecture Specification

Engineering Challenges

A consistent wallet interface needs to account for the differences between blockchain networks, external services and mobile interaction patterns.
01

Different Network Models

Account formats, asset standards and transaction rules vary. Each integration needs to preserve those differences within a consistent product workflow.

02

Recovery and Credential Handling

Self-custody makes credential handling and recovery guidance central to the experience. App access protection and wallet recovery must remain clearly distinguished.

03

Reliable Asset and History Views

Network responses and transaction status can arrive at different times. Loading, refresh and confirmation states need to communicate what is available and what remains pending.

04

Understandable Swap Interactions

Quotes, approvals, fees and route steps introduce complexity. The interface needs to help users understand the action before confirming it.

Product Needs Behind the Build

The product addresses practical needs that arise when users manage assets and interact with applications across networks.

“Assets Across Networks”

Users need a clear way to organize assets even when those assets follow different blockchain rules.

“Clear Self-Custody Responsibilities”

Recovery guidance needs to explain what users must protect and what the wallet operator can recover.

“Accessible Web3 Interactions”

Helping users navigate wallet connections, approvals and provider-dependent transaction steps.

Web3 Adoption Landscape

The Macromodule Solution

Macromodule helped connect wallet capabilities and external integrations through a shared product experience.
  • Asset Management A common interface for supported accounts, tokens and wallet activity.
  • Portfolio Views An organized presentation of asset values and portfolio information.
  • Transaction Workflows Connected transfers, fee information, approvals and status views.
  • Integration Access Wallet interactions with swap services, decentralized applications and supported hardware devices.
Together, these capabilities give the product a foundation for extending supported networks and refining the experience over subsequent releases.

Wallet Architecture and Integration Layers

The product can be explained through four functional layers, separating the application experience from network data and external integration responsibilities.
Layer 01

Mobile Application

Presents navigation, accounts, assets and transaction actions through a consistent interface.

Layer 02

Network Integration

Connects network-specific account, balance and transaction requirements to the wallet's shared workflows.

Layer 03

Asset and Portfolio Data

Organizes token information, valuation inputs and transaction history for display in the application.

Layer 04

Swap and Web3 Integrations

Connects provider-dependent quotes, approvals and application interactions to the relevant wallet flows.

Engineering Approach

The work spans product definition, network integration, transaction behavior and ongoing application refinement.

01. Define the Wallet Experien

Align supported use cases, network requirements and recovery guidance with the intended user journey.

02. Connect Network Workflows

Bring asset handling, transfers and activity views into a common application structure.

03. Integrate Product Capabilities

Connect portfolio, swap and Web3 experiences while accounting for provider responses and transaction states.

04. Refine Through Releases

Continue improving reliability and usability as supported integrations and application requirements evolve.

Every deployment underwent rigorous smart contract static analysis and third-party penetration testing prior to mainnet release.
Self-Custody and User Awareness

Security and Recovery Considerations

A non-custodial wallet needs clear access controls and recovery guidance alongside understandable transaction interactions.

User-Controlled Recovery

LAYER // 01

The recovery phrase remains the user's responsibility. Product guidance must explain safe backup and the limits of operator-assisted recovery.

Protected App Access

LAYER // 02

App access controls support day-to-day privacy on the device. They must be described separately from the mechanisms used to recover a wallet.

Transaction Context

LAYER // 03

Network, asset, fee and approval information help users understand an action before confirming it.

Hardware Wallet Compatibility

LAYER // 04

Hardware integration requires device- and network-specific handling. Compatibility should be stated for supported combinations and releases.
