Building Cross-Chain dApps: Ways to Become Interoperable
Cross-chain Web3 is not the future anymore, it’s a reality that will have an impact on every business in the crypto industry — be it a wallet, a DEX, an NFT marketplace, or any other crypto project that already exists, or is yet to be launched. Can dApps, as a major crypto market player, ignore this trend? Mass adoption, traction, number of users, and many other business indicators fall under the influence of current and future Web3 trends. How does one scale up and grow a successful decentralized application by following today’s market direction? What cross-chain Web3 solutions already exist on the market? Why is Rubic’s Cross-Chain toolkit the ultimate way for any dApp to jump into cross-chain? Get the answers to these questions right in this article!
Why Do dApps Need to Become Cross-Chain?
In this day and age, the blockchain world is witnessing a huge dApp adoption which has soared in the past few years. In total, there are around 4,073 dApps in the crypto space with 80% of them built on Ethereum (2,970 dApps and 117.82k daily transactions to Ethereum dApp contracts).
Given the ever-increasing number of projects, networks, and blockchains, the crypto space is moving toward enhanced interoperability layers, cross-chain messaging, and transferring assets from any chain to any chain. Here is where Cross-Chain Web3 technology comes in. How does it benefit dApps?
Thanks to interoperability and Web3 tech, independent blockchains and networks can communicate with one another, combining their efficiencies, decentralization, features, and sending data & assets freely across the blockchain space, which creates synergy.
Low Costs, More Efficiency
Cross-chain dApps achieve greater scalability, faster transaction times, and higher security. Cross-Chain interoperability reduces operational costs compared to implementation of separate blockchain solutions.
Speaking of business profit, dApps that have implemented cross-chain Web3:
- Increase trading volume & revenue
- Tap into a new user base
- Expand marketing activities with other projects across the blockchain space
When blockchains and networks can communicate with one another, their users and liquidity are not confined to just one ecosystem.
Your dApp becomes open to the entire market!
Cross-Chain Solutions for Token Trading
How can one let all of these dApps and ecosystems communicate with each other?
Let’s dive into several options allowing dApps to go cross-chain.
- Integrating a bridge
Cross-chain bridges allow you to bridge assets from one chain to another. By doing so, you enable the transferring of one asset into its wrapped version on another blockchain. For instance, users will be able to swap $USDT from Polygon into $USDT on BNB. Bridge integration is time-consuming and takes up a lot of development team resources. Another pitfall is that if you want to grow your project into an omnichain ecosystem and cross-chain trading, one bridge will never be enough — you will have to integrate numerous bridges. Moreover, bridges are limited in terms of swappable volume, and if a bridge runs out of liquidity for certain assets, your platform won’t let users make a swap.
2. Deploying your project on several blockchains
Considering a huge amount of time spent on deployment (which can take up to months, not weeks) and expenditures, by launching your project on 4 networks you will split your liquidity. Let’s say, $600 million will become $150 million for each of them. It will diminish your liquidity and degrade your tokenomics. Overall, deployment on other blockchains is a much more time-consuming, expensive, and complicated process than even integrating several bridges.
3. Cross-chain messaging protocols
Cross-chain messaging protocols are designed to move a wider range of information types between chains — in addition to exporting tokens, they can send contract calls, proofs, and states. Cross-chain messaging protocols vary in terms of functionality and operation. For example, IBC is the standard for chain interoperability in the Cosmos ecosystem. The chains adopt and use the IBC messaging standard while light clients in both networks and relayers (those who directly move information) take responsibility for cross-chain interaction. IBC is not suitable for all chains — it’s expensive and inconvenient for chains outside of the Cosmos ecosystem.
To get started with these types of cross-chain tools, one should have a certain degree of expertise and do their due diligence in terms of development issues to understand the pros and cons. It needs time and requires a lot of human resources.
4. Implementing Rubic’s Cross-Chain Tools
Rubic provides the ultimate solution for any crypto project that strives to jump into cross-chain in the most cost-efficient, user-friendly, and fastest way. Compared to the above-mentioned options (bridges, blockchains, cross-messaging protocols), Rubic harnesses all of their benefits: it can aggregate and integrate any of the above-mentioned solutions in one place. With Rubic, you will enable swapping of 15,500+ assets across 18 blockchains in one click, right on your project’s website. Rubic’s toolkit is fast, free, and doesn’t require a lot of coding, human resources, or expertise:
- No need to pack together separate bridges and DEXs anymore, or spend loads of time integrating them.
- No need to hassle your dev team to write new smart contracts or set up your own relayers and validators when launching on other blockchains.
- No need to keep extra servers safe and pay for it.
Due to the aggregation of 70+ DEXs and bridges into Rubic, your dApp will always have smart routing, the best rates, regular updates, and data gathering.
- The turn-key widget will be a great fit for those dApps that value time and effort .
- Our SDK will suit the projects that love to customize and build their own features, since this is a White label solution.
- With Rubic’s NFT widget, dApps get a chance to catch up with the newest trends in the crypto space by enabling their users to purchase NFTs in batches, with more than 15,500 tokens across 18 blockchains, right on their platform.
