How to Add New Blockchain to Trust Wallet

Introduction

If you are building a blockchain project, one of the smartest moves you can make is getting your chain listed on a well-known crypto wallet. Trust Wallet, which is backed by Binance and used by tens of millions of people around the world, sits right at the top of that list. It gives users a simple way to store, send, and receive crypto without handing over control of their private keys. That matters a lot in a space where security and self-custody are becoming non-negotiable for users.

But how do you actually go about adding a new blockchain to Trust Wallet? It is not as simple as filling out a form and waiting. There is a proper technical process involved. You need to handle API integrations, prepare documentation, run security audits, and make sure your blockchain meets the wallet’s standards. For teams without deep blockchain development experience, this can feel overwhelming.

That is exactly where having the right partner helps. At Nadcab Labs, we have spent over 8 years working on blockchain development and integration projects. We have guided multiple projects through the Trust Wallet listing process from start to finish. In this guide, we will break down every step of that journey so you know what to expect and how to prepare.

What is Trust Wallet and Why Does It Matter?

Trust Wallet is a mobile-first, non-custodial cryptocurrency wallet. Non-custodial means that the wallet does not hold your private keys for you. You are in full control of your funds at all times. This is a significant difference compared to centralized exchanges like Binance or Coinbase, where the platform manages your keys on your behalf.

According to Wikipedia, Trust Wallet was founded in 2017 and later acquired by Binance in 2018. Since then, it has grown into one of the most popular decentralized wallets globally. The wallet supports a huge range of blockchains and tokens, and it also includes a built-in DApp browser that lets users interact with decentralized applications directly from their phones.

For blockchain projects, getting listed on Trust Wallet is not just about visibility. It is about meeting your users where they already are. When your blockchain is available on Trust Wallet, anyone using the app can interact with your tokens, participate in your ecosystem, and explore the DApps built on your chain. That kind of access can be a turning point for adoption.

Why Should You Add a New Blockchain to Trust Wallet?

There are practical reasons behind this decision, and they go beyond marketing hype. Let us look at what you actually gain.

First, Trust Wallet has a massive user base. We are talking about 60 million plus active users across the globe. That is an instant audience for your blockchain project. Even if only a small percentage of those users interact with your tokens, the numbers add up fast.

Second, it builds credibility. When a blockchain project is listed on a reputable wallet like Trust Wallet, it signals to investors and users that the project has gone through a legitimate vetting process. It shows that the technical infrastructure is solid enough to be supported by one of the largest wallets in the market.

Third, it simplifies the user experience. Instead of asking your users to set up custom RPC endpoints or manually add network configurations, they can simply find your blockchain within Trust Wallet and start using it. That reduction in friction can have a direct impact on user retention and engagement. Understanding how different cryptographic protocols on blockchain systems work can give you a better picture of what Trust Wallet evaluates before supporting a new chain.

How Trust Wallet Blockchain Integration Actually Works

The integration process is not a single event. It is a series of carefully coordinated steps that involve development, documentation, review, and testing. Let us walk through what happens behind the scenes.

Trust Wallet is open source. Its core code is available on GitHub, and contributions from blockchain projects are welcome. The standard path for adding a new blockchain involves submitting a pull request to the Trust Wallet Assets repository. But the real work happens before that submission. Your blockchain must have a functioning mainnet, a stable node infrastructure, proper block explorer support, and well-documented API endpoints.

At Nadcab Labs, we start every integration project with a thorough assessment. We evaluate the blockchain’s consensus mechanism, its transaction format, how it handles addresses, and the overall architecture. This assessment helps us identify potential compatibility issues early so we can address them before they become blockers.

The reason this matters is simple. Trust Wallet needs to reliably query your blockchain for balances, transaction histories, and network status. If any of those queries fail or return inconsistent data, the integration will not pass review. Our team’s experience with over 200 blockchain projects means we know exactly what Trust Wallet’s reviewers are looking for.

The Integration Lifecycle: From Planning to Deployment

Every blockchain goes through a defined lifecycle before it appears on Trust Wallet. Understanding this lifecycle helps you plan your timeline and allocate resources properly. Here is how it breaks down:

Phase	Activities	Typical Duration
Research and Planning	Evaluate blockchain specs, consensus type, address format, and Trust Wallet compatibility	1 to 2 weeks
Technical Development	Build API integrations, configure RPC nodes, set up block explorer connectivity	2 to 4 weeks
Testing and Audit	Run testnet transactions, verify balance queries, stress-test node responses	1 to 3 weeks
Documentation and Compliance	Prepare network specs, token details, logo assets, and compliance paperwork	1 to 2 weeks
Deployment and Launch	Submit PR to Trust Wallet GitHub, address review feedback, go live	1 to 2 weeks

The total timeline usually falls between 4 and 12 weeks. Projects with well-documented code and stable mainnets tend to move through faster. Projects that are still working out bugs in their node software or have inconsistent block times often face delays during the review stage.

One thing we always tell our clients at Nadcab Labs is this: preparation is everything. The more polished your technical stack is before we begin the integration, the smoother the entire process will be. Our team handles the heavy lifting, but having a stable foundation to build on makes a real difference.

Step-by-Step Process to Add Your Blockchain to Trust Wallet

Let us get into the specific steps involved. This is the process we follow at Nadcab Labs for every Trust Wallet integration project.

Step 1: Blockchain Readiness Assessment

Before anything else, we check whether your blockchain is ready for integration. This means verifying that your mainnet is live and stable, your nodes are publicly accessible, your block explorer is functional, and your transaction format is well-defined. If you are running a blockchain based on a Delegated Proof of Stake (DPoS) mechanism, there are specific node requirements that need to be met. We check all of these upfront.

Step 2: Fork and Configure the Trust Wallet Core Library

Trust Wallet uses an open-source library called Wallet Core. To add support for a new blockchain, you need to fork this library and add the chain-specific logic. This includes defining the address derivation path, transaction signing methods, and serialization formats. Our developers have contributed to dozens of Wallet Core forks, so we know the codebase inside and out.

Step 3: API and Node Integration

Trust Wallet needs to communicate with your blockchain. That means setting up reliable RPC endpoints or REST APIs that can handle balance queries, transaction broadcasting, and history retrieval. Node reliability is critical here. If your nodes go down or respond slowly, the wallet experience suffers. We help projects set up redundant node infrastructure so there is always a fallback. This is closely related to how node synchronization in blockchain networks works, and why getting it right is essential for wallet integrations.

Step 4: Asset Repository Submission

Once the technical integration is ready, the next step is adding your blockchain and token information to the Trust Wallet Assets repository on GitHub. This includes your chain’s logo, token logos, network details, and metadata. Everything has to follow Trust Wallet’s formatting guidelines exactly. A small mistake in the JSON file or an incorrectly sized logo can result in a rejected pull request.

Step 5: Testing on Testnet and Mainnet

We run extensive tests before submitting anything for review. This includes sending and receiving transactions on both testnet and mainnet, checking balance accuracy across multiple wallets, and verifying that the DApp browser can interact with smart contracts on your chain. If you are wondering how testnets fit into this picture, you might find it useful to read about the 7 popular testnets for blockchain development and how they are used in real-world projects.

Step 6: Review and Iteration

After submission, the Trust Wallet team reviews your pull request. They may request changes, ask for clarifications, or flag issues with your implementation. This back-and-forth is normal. Our team at Nadcab Labs stays on top of every review cycle, responding quickly and making the necessary adjustments. This is where having an experienced integration partner really pays off. We know the common pitfalls and can address feedback faster than teams doing this for the first time.

Step 7: Go Live

Once your pull request is merged, your blockchain is officially available on Trust Wallet. Users can now see your chain in the wallet, add custom tokens, and interact with your DApps through the built-in browser. It is a big milestone, and it usually comes with a noticeable bump in user activity and token transactions.

Technical Requirements for Trust Wallet Integration

Trust Wallet does not accept just any blockchain. There are specific technical requirements that your project must meet. Here is a breakdown of the most important ones:

Requirement	Details	Why It Matters
Live Mainnet	Your blockchain must be fully operational with a public mainnet	Trust Wallet will not list testnets or pre-launch chains
Public RPC/API Endpoints	Accessible and reliable endpoints for querying the chain	The wallet relies on these to show balances and process transactions
Block Explorer	A working block explorer that users can verify transactions on	Transparency and user trust depend on transaction verification
Token Standard	ERC-20, BEP-20, SPL, or your chain’s native standard must be well defined	Proper token standards ensure wallet compatibility
Logo and Branding Assets	High-resolution PNG logos (256×256) in the correct format	Required for the asset repository and user-facing display
Documentation	Complete network specs, coin type registration, and protocol documentation	Reviewers use this to evaluate your submission

One area where we see projects struggle is with token standards. If your blockchain uses a custom token standard that is not widely known, you will need extra documentation to explain how it works. Interestingly, newer standards like ERC-433 for better blockchain transactions are starting to gain traction, though Trust Wallet currently focuses on established standards.

How Trust Wallet Compares to Other Wallets for Integration

Before committing to a wallet integration, it helps to understand how Trust Wallet stacks up against other popular options. Each wallet has its own strengths and limitations, and your choice should depend on where your target audience actually is.

Parameter	Trust Wallet	MetaMask	Coinbase Wallet
Multi-Chain Support	70+ blockchains	EVM chains only	10+ blockchains
Platform Focus	Mobile first	Browser extension first	Mobile and extension
Integration Complexity	Moderate (GitHub PR-based)	Low for EVM, high for non-EVM	Partnership-based
DApp Browser	Built-in	Built-in	Built-in
Open Source	Yes, fully open source	Partially open source	No
User Base	60M+ active users	30M+ active users	10M+ active users

Trust Wallet clearly wins on multi-chain support and user base size. If your blockchain is not EVM-compatible, Trust Wallet is especially attractive because MetaMask does not natively support non-EVM chains. The open-source nature of Trust Wallet also means you have full visibility into how your blockchain will be integrated, which is a big plus for transparency.

Many of the blockchain projects we work with at Nadcab Labs need integration across multiple wallets. We often start with Trust Wallet because it offers the broadest reach, and then extend to other wallets based on the project’s target markets.

Security Considerations When Adding a Blockchain to Trust Wallet

Security is not something you add at the end of the integration process. It has to be baked in from day one. Trust Wallet takes this seriously, and so do we.

When we integrate a new blockchain into Trust Wallet, there are four main security areas we focus on.

Private Key Management: Trust Wallet generates and stores private keys locally on the user’s device. When adding a new blockchain, the key derivation path must follow BIP-44 standards or whatever standard your chain uses. Any deviation must be thoroughly documented and tested to make sure keys are generated correctly and consistently.

Transaction Signing: Every transaction on your blockchain needs to be signed locally on the device before being broadcast to the network. The signing logic has to be airtight. A bug in the transaction signing code could lead to lost funds, which is the worst possible outcome for any wallet integration.

Smart Contract Audit: If your blockchain supports smart contracts, and most do these days, those contracts need to be audited by a reputable third party. Trust Wallet’s review team will want to see audit reports before approving your integration. This is especially important if your blockchain uses techniques like Plasma in blockchain for scaling, since those add another layer of complexity that must be verified.

Network Security: Your blockchain’s network must be robust enough to resist common attacks. This includes 51% attacks, Sybil attacks, and DDoS attempts. Trust Wallet does not want to list a chain that could suffer a catastrophic failure, as that would reflect poorly on the wallet itself. A solid understanding of how sidechain pegs in blockchain function can be particularly relevant if your project involves cross-chain bridges or interoperability layers.

At Nadcab Labs, our security team has handled audits and security reviews for over 150 blockchain projects. We know what vulnerabilities to look for and how to fix them before they become problems during the Trust Wallet review process.

Common Challenges and How to Overcome Them

No integration project is completely smooth. There are always bumps along the way. Here are some of the most common challenges we have seen over the years and how we address them.

Inconsistent Node Responses: This is probably the number one issue. If your RPC nodes return slightly different data for the same query, it creates problems for the wallet’s balance display and transaction history. The fix is straightforward but requires attention: set up multiple nodes behind a load balancer and make sure they are all synced to the same block height. If you want to dig deeper into this topic, our guide on node synchronization in blockchain covers the technical details.

Non-Standard Address Formats: Some blockchains use address formats that do not follow common conventions. While this is fine from a technical standpoint, it means extra work during integration. The address validation logic in Wallet Core needs to be customized, and the checksum algorithm has to be implemented correctly.

Slow Block Times: If your blockchain has unusually long block times, users may experience delays when checking balances or waiting for transaction confirmations. We work with projects to optimize their node configurations and sometimes suggest caching strategies to improve the wallet’s responsiveness.

Incomplete Documentation: Trust Wallet’s review team relies on your documentation to understand your blockchain. If it is incomplete or unclear, the review process stalls. We have seen projects lose weeks because their documentation was missing basic details like coin type numbers or address encoding specifications. Our documentation team at Nadcab Labs prepares everything from scratch when needed, following Trust Wallet’s exact formatting requirements.

Projects that have dealt with orphan blocks in their blockchain know how frustrating chain reorganizations can be. During Trust Wallet integration, we specifically test how the wallet handles orphan blocks and chain reorgs to make sure user balances are always displayed accurately.

The Role of Blockchain Scalability in Wallet Integration

Scalability is another factor that directly affects how well your blockchain works within Trust Wallet. A blockchain that can handle a high volume of transactions per second provides a better experience for wallet users. Slow transaction processing leads to long confirmation times, which frustrates users.

This is where newer scaling solutions come into play. Layer 3 blockchains are starting to offer interesting approaches to scalability that could make wallet integration even smoother in the future. By offloading specific application-level transactions to a dedicated layer, these chains can maintain high throughput without congesting the base layer.

At Nadcab Labs, we always evaluate a blockchain’s scalability profile before starting the integration process. If we identify potential bottlenecks, we work with the project team to address them. This might involve optimizing block sizes, adjusting gas parameters, or implementing state pruning to keep node storage requirements manageable.

The connection between scalability and wallet integration is straightforward. The more transactions your blockchain can process efficiently, the better the experience will be for Trust Wallet users. And a good user experience drives adoption, which is the whole point of getting listed in the first place.

Real-World Use Cases: Blockchain Integration Beyond Crypto

Trust Wallet integration is not just about cryptocurrency trading. The use cases are expanding rapidly. Blockchains focused on supply chain management, decentralized identity, and even smart cities using blockchain for energy management are now seeking wallet listings to give their users easy access to native tokens.

For example, a blockchain project focused on decentralized energy trading might issue tokens that represent energy credits. By listing on Trust Wallet, users in participating smart cities could easily store and transfer these credits from their phones. The wallet becomes the gateway to a real-world utility, not just a tool for speculation.

We have worked with projects across multiple verticals at Nadcab Labs. From DeFi platforms and NFT marketplaces to enterprise blockchain solutions, the integration process follows the same core principles. What changes is the specific configuration and the documentation that supports it.
