🪢 Chainge's cross-chain roaming is the only universal interoperability solution that is decentralized, multi-operational and 100% secure.

So why is our interoperability solution superior?
1⃣ Multiple cross-chain operations performed simultaneously. Assets become chain-agnostic.
Eg: #USDT spread across 12 CHAINS can be instantly "bridged" to 1 destination chain OR swapped with one tap, within 2 minutes.

2⃣ Chainge is the ONLY aggregator that CAN aggregate liquidity cross-chain. Meaning we are the most liquid DEX aggregator on the market, offering the absolute best prices.
A cross-chain aggregated swap implies it being split on multiple liquid chains:

#CCTP eliminates the need for conventional "lock-and-mint" bridges that fragment liquidity & allows devs to provide users a more capital efficient way to transfer $USDC

2/ Burn $USDC on the source chain:
User initiates transfer of #USDC through an app from one chain to another, and specifies the recipient wallet address on the destination chain. The app facilitates a burn of USDC on the source chain.

3/ Fetch attestation from Circle:
Circle observes and attests to the burn event on the source chain. The app requests a signed attestation from Circle, which provides authorization to mint the specified amount of #USDC on the destination chain.

1. Always have a plan
Planning helps you learn about the problem, analyse it, and carefully think about the trade-offs. Jumping right into the code is often a sign of inexperience.

2. Optimize only when needed

Node.js is based on the V8 JavaScript engine developed by Google, which means it compiles and executes JavaScript code at high speed. This makes it an ideal choice for building real-time, data-intensive applications.

One of the key advantages of using Node.js is its event-driven, non-blocking I/O model. This means that it can handle a large number of concurrent connections with minimal overhead, making it perfect for applications that require high scalability.

It was a report clients were asking for; they log in, enter their credentials, enter a date range, set some filters — and then the system would literally take up to three full minutes to fully load the report.
You literally got a blank screen for several minutes.

The database folks are barking: "our infrastructure prevents us from doing this any other way, dev needs to do things differently." #Developers fire back: "it's a needlessly complex data structure." #UX folks are angry with both groups: "we TOLD you this would happen."

@verodigiorgio at #CodemotionMilan22 answering the question on how to grow professionally (as software architect for her, but it’s the same for all paths in #softaredevelopment). Let’s discuss about it in this thread 🧵 👇🏻
Let me introduce the thread saying that the talk by @verodigiorgio at #CodemotionMilan22 about #gitops was very helpful and rich of content and points of inspiration. Surely something to try in every day company business to improve our products, developer and customer experience.
Next, going straight to the point what @verodigiorgio says here is that #curiosity and the ability to face our ideas with other #developers (or more generally other colleagues in the business having another point of view) are fundamentals point for growth and success.
