Introduction & Overview
What is Trust Wallet?
Trust Wallet is a decentralized, non-custodial mobile cryptocurrency wallet that supports Ethereum-based (ERC-20, ERC-721, ERC-1155) and other blockchain assets including Bitcoin, BNB Chain, Solana, and more. Initially developed for mobile use, Trust Wallet allows users to securely store, manage, and interact with blockchain assets and decentralized applications (DApps).
History or Background
- Founded: 2017 by Viktor Radchenko
- Acquisition: Acquired by Binance in 2018
- Development Focus: Security-first approach to mobile wallet design, emphasizing open-source architecture and support for DeFi and NFTs.
- Open-Source Contribution: Partial components like the Trust Wallet Core (blockchain integrations) are open-sourced on GitHub.
Why is it Relevant in DevSecOps?
In a DevSecOps context, Trust Wallet plays a unique role in secure development, testing, and interaction with decentralized systems:
- Acts as a secure credential store or signing tool for decentralized applications (dApps) during testing.
- Used in automated contract deployment pipelines.
- Enables secure identity and key management for developers and bots in Web3-native DevSecOps pipelines.
- Supports cold-signing for CI/CD processes interacting with blockchains.
Core Concepts & Terminology
Key Terms and Definitions
| Term | Definition |
|---|---|
| Private Key | A secret key used to authorize blockchain transactions. |
| Seed Phrase | A 12-24 word mnemonic used to recover a wallet. |
| DApp Browser | In-app browser in Trust Wallet to interact with decentralized applications. |
| Non-Custodial | A wallet where users fully control their keys and funds. |
| Smart Contract | Code that runs on blockchain platforms like Ethereum or BNB Chain. |
How It Fits into the DevSecOps Lifecycle
| DevSecOps Phase | Trust Wallet Role |
|---|---|
| Plan | Integration with secure development plans involving Web3. |

Integration Points with CI/CD or Cloud Tools
- WalletConnect Integration: Trigger secure transactions from Jenkins, GitHub Actions, or GitLab via WalletConnect QR and approval.
- Secure Signing Pipelines: Developers export cold keys to sign smart contracts during builds.
- Infrastructure as Code (IaC): Use Trust Wallet for secure parameter storage and verification for blockchain-based IaC.
Installation & Getting Started
Basic Setup or Prerequisites
- Android/iOS device
- Trust Wallet app (Download)
- Seed phrase backup strategy (e.g., encrypted secret manager or manual)
- Blockchain testnet tokens (e.g., Goerli ETH) for testing
Hands-on: Step-by-Step Setup Guide
- Install the App
- Visit trustwallet.com → Download for Android/iOS
- Create a New Wallet
- Open app → Tap “Create Wallet”
- Securely store your 12-word seed phrase
- Add Custom Tokens (Optional)
- Tap “Add Token” → Choose network (e.g., Polygon, Solana)
- Enable DApp Browser (Android only)
- Open Settings → Preferences → Enable DApp Browser
- Connect with WalletConnect
- On your DevSecOps tool or DApp (e.g., Truffle, Hardhat UI) → Click “Connect Wallet”
- Scan QR Code from Trust Wallet
- Sign Transaction
- Approve or reject signed transaction securely via Trust Wallet
Real-World Use Cases
1. Smart Contract CI/CD Pipeline
- CI/CD process in GitHub Actions auto-deploys contracts using Hardhat.
- Final transaction requires manual approval via Trust Wallet.
- Ensures secure release gatekeeping.
2. Key Management for DeFi Developers
- Developers keep private keys on Trust Wallet and use WalletConnect during test runs.
- Reduces attack surface of hot wallets in dev environments.
3. Compliance-Driven Blockchain Deployment
- Regulated firms use Trust Wallet for human-verified cold signing before pushing changes to Ethereum Mainnet.
- Ensures full audit trail.
4. Web3 API Integration with Multi-Sig
- Used as part of a multi-signature scheme via Gnosis Safe.
- Trust Wallet signs approval transactions before code is executed.
Benefits & Limitations
Key Advantages
- 🔐 Security-First: Local, encrypted private key storage.
- 📱 Mobile-native: Portable and easily accessible.
- 🌐 Multi-chain support: Compatible with Ethereum, BNB Chain, Solana, and more.
- 🔗 WalletConnect: Seamless CI/CD and DApp integration.
Common Challenges
| Limitation | Description |
