Developing for Trust Wallet platform

1. Why build for Trust Wallet

Reach & trust

Trust Wallet is a widely-used mobile wallet and open-source platform that gives developers safe, lightweight primitives (Wallet Core, WalletConnect, and specialized SDKs) to integrate account management, signing, and token support. Building with Trust means connecting to users who prioritize non-custodial ownership and familiar UX flows.

Core building blocks

Key components you’ll use: Wallet Core (crypto primitives & cross-platform SDK), WalletConnect / deep linking (mobile dApp connections), token & asset repositories (for logos & metadata), and optional smart-account tooling (Barz / Smart Accounts for batched/gasless flows).

2. Integration patterns

H4: Mobile — WalletConnect & deep links

For mobile dApps, WalletConnect is the standard: QR or deep-link handoff creates a websocket JSON-RPC channel for signing and transaction flow. Use Trust’s docs and SDKs that implement WalletConnect to simplify mobile flows.

H4: Native — Wallet Core

Wallet Core offers low-level crypto and signing across many blockchains. It is ideal for native wallet apps or backend utilities that need deterministic, cross-language signing (Swift, Java/Kotlin, C++).

H4: Smart accounts & advanced UX

Smart Accounts (Account Abstraction / ERC-4337 style) and solutions like Barz enable gasless or batched transactions — useful when you want to abstract gas UX from end users while keeping keys non-custodial.

3. Practical checklist (developer-ready)

H5: Before you start

Read the Trust Developer docs and Wallet Core integration guides.
Decide on connection flow (WalletConnect vs deep link vs browser extension).
Prepare RPC endpoints that meet Trust’s RPC/API requirements if integrating a new chain.
Submit dApp or token listing if you want visibility in the Trust ecosystem.

Pro tip: test signing UX thoroughly (EIP-712 messages, human-readable summaries) — users reject ambiguous signature prompts.

4. Official resources (10 links)

Use those links as your starting launchpad: docs for policies and APIs, GitHub for code & samples, blog guides for common patterns, and Support for listing and ecosystem questions.

5. Next steps & recommended approach

Start with a small integration (WalletConnect handshake + a sample signing flow), include friendly EIP-712 messages, then expand to Wallet Core if you need native signing or multi-blockchain support. If your dApp needs account abstraction, prototype with Barz or an ERC-4337 framework and test batched transactions.

Document your UX and gather user feedback early — security and clear signing language are the most critical trust signals.
