cross-chain

In this episode of "Crypto Hidden Gems by Token Metrics," we delve into several intriguing projects that have caught our eye through our fundamental analysis process. We cover Magpie, Socket, LI.FI, Koii Network, and Superform—each offering unique solutions in the realms of cross-chain interoperability, DeFi, and decentralized internet. From liquidity aggregation protocols and interoperability solutions to a decentralized marketplace for cryptocurrency yields, we explore the potential these projects hold for the crypto ecosystem. Please note, some projects are yet in the review process for further evaluation.

In this episode of "Crypto Code Reviews by Token Metrics," we take an in-depth look at Connext, a protocol designed to facilitate seamless cross-chain interactions. Discover how Connext's modular design, robust architecture, and commitment to code quality and usability position it as a frontrunner in blockchain interoperability. Join us as we analyze its potential to revolutionize the way developers create cross-chain applications.

While competition fosters innovation, the proliferation of different blockchains has resulted in the fragmentation and isolation of liquidity within each ecosystem. Early attempts to address this issue primarily involved bridges and wrapped assets. Unfortunately, these solutions were often vulnerable to hacks and exploits, and the value of wrapped assets was contingent on the security of the wrapper contract, rather than the underlying asset. Cross-chain swaps of native assets hold the promise of resolving liquidity fragmentation, but numerous technological challenges must be overcome to make them as seamless as same-chain swaps.

We were joined by Simon Harman, founder of Chainflip, to discuss multi-chain liquidity fragmentation and how Chainflip’s JIT AMM (Just in Time) aims to solve this, by providing cross-chain native swaps.

Topics covered in this episode:

• Simon’s background
• (Legacy) Bridging vs. Threshold Signature Scheme
• Chainflip’s Just in Time (JIT) AMM vs. Uniswap’s V3/X
• Providing liquidity on Chainflip
• Slippage and UX
• Deciding trading pairs
• Chainflip validators
• Validator stake auctions
• Governance
• Roadmap and bootstrapping liquidity

Dive into the world of blockchain interoperability as we dissect the LayerZero protocol. From its innovative approach to cross-chain communication to its robust architecture, uncover what sets LayerZero apart in the burgeoning blockchain ecosystem.

On the Devs Do Something podcast, we bring you technical discussions with some of the best and brightest engineers in all of web3. Today, we have Rahul Sethuram - CTO & cofounder of Connext.

Connext is building the first fully trust-minimized Crosschain Communication protocol to make blockchains composable.

Rahul has been in the space for the better part of 5 years - he started his career at tesla and worked in various startups business before getting into crypto. In this episode, you’ll hear more about his journey through the proverbial idea maze as he iterated his way into building Connext, and you’ll also get an inside look into the technical side of building cross chain infrastructure.

In this episode, we hit on a ton of fascinating technical topics: you’ll hear us walk through optimistic bridge design, Connext’s engineering & design process (including how they navigated multiple re-writes), Rahul’s favorite non-EVM tech in the space, & we’ll even walk through the full lifecycle of a cross chain operation on Connext.

If you’re a web3 engineer or work alongside engineers, we think you’ll get a lot of value from this one.

Yogesh Srihari is a serial entrepreneur, who started several companies until he stumbled upon blockchain and was convinced by its potential to refocus his attention. Now, he is co-founder and CEO at LQDEX (pronounced "liquid-ex"), an inter-blockchain trading platform which allows trading of digital tokens across multiple blockchains. Because the exchange is decentralized, all the trading can be done without counterparty risk. Cross-chain trading often utilizes what are called atomic swaps. We explore what atomic swaps are, and why LQDEX does not use them, so therefore does not require modifications to the existing blockchains.

As he discusses his past with Spankchain, Yogesh tells of the lessons he learned to not only build a great product, but to become an effective leader and decision-maker.

In this episode, we also cover:

• How the adult entertainment industry has catalyzed other technologies in the past
• Launch of the LQDEX Bridge
• Collators in the LQDEX ecosystem, why they're crucial to the system
• Ensuring good behavior from those participating on the platform by issuing LQD tokens
• Stake and earn token models
• Training yourself to become a hyper-rational thinker
• Using a sidechain for more efficient cross-chain trading
