Introducing TrustConnect SDK: The free, open-source wallet connection library for every chain by Trust Wallet

We're excited to introduce TrustConnect SDK, Trust Wallet's first-party wallet connection library for web3 developers. It's free, open-source, and built for multi-chain from the ground up — giving developers everything they need to connect wallets across EVM, Bitcoin, and Solana without paying per user, negotiating licensing tiers, or stitching together multiple SDKs.

Now, we're making that infrastructure available to every developer building on Web3.

What is TrustConnect SDK?

TrustConnect SDK is a wallet connection library that lets developers add wallet connectivity to any web3 app — quickly, cleanly, and without third-party licensing costs.

It's modular and lightweight by design. You get a small bundle footprint, minimal dependencies, and a fully customizable UI layer that you can style to match your existing design system. There's no imposed branding, no locked-in defaults, and no vendor relationship to manage.

TrustConnect is released under the Apache 2.0 license. That means you can fork it, extend it, modify it, and ship it — for any project, commercial or otherwise.

What It Supports

TrustConnect SDK offers native multi-chain wallet connection in a single package:

• EVM chains — full compatibility across the Ethereum ecosystem and EVM-compatible networks

• Bitcoin — native support, not an afterthought

• Solana — included from day one

• Multiple wallets — TrustConnect is multi-wallet by design; Trust Wallet is one of the supported options, not the only one

No additional SDKs required. One integration, every chain.

Why Developers Are Switching

The wallet connection SDK market has a pricing problem.

Most established options charge based on monthly active users. For small teams and indie builders, this is manageable early on. As a dApp grows, those costs compound, and switching becomes disruptive. Developers find themselves locked in to pricing models that punish their own success.

Existing free alternatives are often EVM-only, forcing teams building cross-chain products to add more dependencies, more maintenance burden, and more surface area.

TrustConnect was designed to eliminate that trade-off. It's free to use, with no MAU-based pricing. It supports multiple chains natively. And because it's Apache 2.0 licensed, there's no vendor relationship at all — you own the integration.

How to Get Started

Getting TrustConnect into your project takes minutes:

1. Install the SDK via npm or your preferred package manager.

2. Import and configure — add your supported chains and wallet options in a single config object.

3. Customize the UI — override styles to match your design system, or ship the default theme.

4. Connect — your users can now connect any supported wallet across EVM, Bitcoin, and Solana.

Full documentation, code examples, and a quickstart guide are available at developer.trustwallet.com.

Built to Grow With You

TrustConnect started as an internal tool. Trust Wallet's own web products were built on third-party wallet connection SDKs. As our product surface expanded, so did the costs and constraints.

We built TrustConnect to solve that for ourselves. We're releasing it because the same problem affects developers everywhere.

Because the SDK is open-source, the community can contribute, flag issues, and shape its direction.

This is developer infrastructure you can rely on. It's the same tooling we use ourselves.
