## **What Is Interlay Network (INTR)?**

Interlay is a modular, programmable layer between Bitcoin and the multi-chain ecosystem that unlocks decentralized (financial) use cases for BTC.

Interlay’s vision is to help Bitcoin achieve mass adoption by unlocking decentralized (financial) use cases for BTC and removing the need for centralized services. Interlay’s achieves this by creating the necessary infrastructure and financial tooling for both users and builders:

* **DeFi for Bitcoin**: Interlay’s DeFi hub a one-stop shop for all things decentralized Bitcoin finance featuring BTC swaps, lending, and staking. High throughput, low fees payable in any asset, and native stablecoin integrations aim to provide an experience competing even with centralized providers.

* **Bitcoin for DeFi**: Interlay’s BTC bridge is the secure way to use Bitcoin in the multi-chain ecosystem. iBTC, a 1:1 BTC-backed asset, is secured by a decentralized network of vaults. BTC deposits are insured by a multi-collateral system and secured by cross-chain light clients.

* **Building Bitcoin dApps**: Interlay will support Bitcoin dApp development on top of its modular network.

The INTR governance and utility token’s main purposes are:

* Stake-to-vote. Lock INTR to participate in governance & earn staking rewards. The longer the lock, the higher to voting power & staking rewards.
* Utility. Transaction and cross-chain fees can be paid in INTR.
* Collateral. INTR can be used as one of the collaterals to back iBTC and other Interlay assets.
* Outlook: Product benefits: In the future, INTR may offer stakers additional security and product benefits, e.g. better liquidation and collateral rates, or lower swap fees.

The Interlay network launched on 11 March 2022.

## **How Many INTR Coins Are There in Circulation?**


INTR features an unlimited supply. The emission schedule is defined as follows:

* 1 billion (1,000,000,000) INTR emitted over the first 4 years
* 2% annual inflation afterwards, allocated to the protocol treasury to fund future development and maintenance.

70% of the supply is distributed to the community as airdrops and block rewards: 30% to Vault rewards 5% to governance staking rewards (“stake-to-vote”), and 35% to the on-chain treasury controlled by network governance (of which 10% are airdropped during the first crowdloan). 10% are allocated to a reserve, to be spent on network development and community & ecosystem building. 20% are airdropped to the (current and future) team and early backers who funded the initial development.


### **Who Are the Founders of Interlay Network?**

Interlay was created by Alexei Zamyatin and Dominik Harz. The two met in 2017 during their PhDs at Imperial College London where they were the first researchers in the cryptocurrency lab. Both have been researching Bitcoin and Ethereum since 2015/16, authoring over [30 papers with over 1000 citations](https://docs.interlay.io/#/about/research). Both regularly presented their work at Bitcoin and Ethereum conferences, including DevCon IV, EthCC, Building on Bitcoin, and Breaking Bitcoin.

The first steps towards Interlay and Interlay were made when the XCLAIM paper was presented at the Scaling Bitcoin in 2018 - describing the first-ever protocol to move cryptocurrencies like Bitcoin to Ethereum in an economically trustless and decentralized manner. In 2020, the two founded Interlay to bring research into practice. Today, Interlay employs 23 staff, including developers with experience at Google, Morgan Stanley, Trivago, Accenture, PwC, Worldpay, and Atlassian.


### **What Makes Interlay Unique?**

Interlay is a modular, programmable layer situated between Bitcoin and the multichain ecosystem. It is the only Bitcoin-centric layer 1 that is decentralized across the entire stack: from trustless BTC bridge to BTC DeFi hub

Leveraging BTC as the main reserve asset and source of liquidity, Interlay’s stack provides a set of custody and bridge tools that allow applications to tailor asset management to their specific use case. Structured as a marketplace, Interlay already supports collateralized bridges, and will add threshold shared custody (incl. institutions and 3rd party providers), as well as discrete log contracts (DLCs), and zero-knowledge contingent payments (ZKCPs). To enhance security and user experience, Interlay will incorporate social sign-in options like Google-sign in and opt-in recovery mechanisms via federation counter-signing and identity verification.

Interlay is launching both EVM (for compatibility) and Rust smart contracts that are optimal for BTC-centric development (compatible with widely adopted Bitcoin-core libraries and tooling). Thereby, builders can seamlessly access built-in DeFi tooling (AMM and lending) and assets from other ecosystems, including stablecoins and blue-chip L1 assets. This puts Interlay in a unique position to help improve upon the rather centralized BTC stack (Lightning nodes, Nostr servers, indexers, CEXes) with decentralized custody and smart contracts.

Karura is an all-in-one decentralized finance (DeFi) hub and stablecoin platform built on Kusama (KSM) and integrated into Polkadot (DOT). Karura was created by the Acala Network, which has won four Web3 Foundation grants and founded the Substrate Developer Academy.

To learn more about this project, check out our deep dive of Karura.

Both Karura and Acala are backed by multiple funds, including Coinbase Ventures, Pantera Capital, Polychain Capital and Hypersphere. Karura and Acala operate in parallel. Specifically, Karura is implementing DeFi on Kusama in the same way that Acala is offering DeFi on Polkadot. The network is built with almost the same codebase as Acala: the two platforms provide scalable, convenient and fast DeFi cross-chain ecosystems for Kusama and Polkadot.

Parachain Karura is a platform that allows users to create effective, low-cost and complex financial applications, saving time and increasing trading efficiency.

The platform itself provides a multi-collateralized stablecoin backed by cross-chain assets (kUSD), a trustless staking derivative (liquid KSM), and an automated market maker (AMM) decentralized exchange (DEX) for unlocking liquidity and supporting financial innovation.

Karura is the decentralized financial hub of Kusama, a scalable multi-chain network for radical innovation and early-stage Polkadot deployments. Karura is the sister network to Acala. It hosts multichain liquid staking token (LST) protocols (such as liquid KSM - LKSM), an AMM decentralized exchange, and an app platform that is EVM-compatible and highly customizable (based on Substrate). Karura is secured by Kusama, and is the liquidity gateway of Kusama parachains, Acala and L1/L2 blockchains

Centrifuge is a decentralized asset financing protocol. It connects decentralized finance (DeFi) with real-world assets (RWA) while trying to lower the cost of capital for small and mid-size enterprises (SMEs) and provide investors with a stable source of income. The main goal of the project is to generate profits that are not tied to volatile crypto assets; the developers are pursuing the task of transferring real monetary value from fiat to cryptocurrencies.

Companies are using Centrifuge to access the liquidity that DeFi has to offer. They can tokenize real assets and use these tokens as collateral to access financing through Tinlake, a decentralized application (DApp) lending protocol. The Centrifuge blockchain is built on Polkadot (DOT) for speed and low fees, while its financial DApp Tinlake is built to access Ethereum (ETH) liquidity.

Centrifuge provides liquidity to everyone and investors receive income and rewards in the form of CFG tokens. Centrifuge links assets such as invoices, real estate and royalties with decentralized finance (DeFi). Additionally, borrowers benefit from the fact that they can finance their real assets without banks or other intermediaries.

Astar Network helps developers build decentralized applications (dApps) and layer 2 solutions by providing interoperable web 3.0 infrastructure, financial incentives, incubation programmes and technical support. It seeks to provide the best solution for all developers by supporting EVM and making a parachain where EVM and WASM smart contracts can co-exist and communicate with each other.

Astar connects the Polkadot ecosystem with layer 1 blockchains like Ethereum and Cosmos. It's a Polkadot Parachain, and was designed as a multi-chain Polkadot dApp hub with support for DeFi, NFTs, DAOs, where developers can move beyond infrastructure and focus more on application development.

The project, which is backed by Binance Labs and Coinbase Ventures, operates on two layers: the first layer is built on the Substrate framework, and the second is built using OVM or Optimistic Virtual Machine, for scalability.

Moonbeam is an Ethereum-compatible smart contract parachain on Polkadot. Moonbeam makes it easy to use popular Ethereum developer tools to build or redeploy Solidity projects in a Substrate-based environment.

Moonbeam is much more than just an EVM implementation: it’s a highly specialized parachain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonbeam platform extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations.

Moonbeam’s Ethereum compatibility is unmatched:

Minimal Changes: developers can use existing Solidity smart contracts right away, with no need to rewrite or reconfigure

Use Existing Developer Tools: connect popular tools like MetaMask, Hardhat, Waffle, Remix, and Truffle via a complete set of Web3 RPC endpoints. Use well-known Javascript libraries such as Web3.Js or Ethers.Js.

Unified Accounts, Addresses, and Signatures: use your existing Ethereum H160 accounts & ECDSA signatures to interact with Moonbeam

Tap into the Most Integrations on Polkadot: use existing oracles, bridges, wallets, and other tools that are already building on Moonbeam

Moonbeam provides integration and connectivity between Polkadot Parachains as well as with other chains such as Ethereum and Bitcoin via bridges. Moonbeam was started in 2019 by Derek Yoo of Pure Stake.

Self-described as "Polkadot's wild cousin," Kusama is an experimental blockchain platform that is designed to provide a massively interoperable and scalable framework for developers.

Kusama is built on Substrate — a blockchain building kit developed by Parity Technologies. Kusama has almost the same codebase as Polkadot — one of the most successful interoperable blockchains.

By deploying on Kusama, fast-paced projects gain access to a highly scalable, interoperable sharded network, with features that are not yet available on Polkadot. To that end, Kusama describes itself as a “canary network.”

The platform is designed to provide a testbed for developers looking to innovate and deploy their own blockchain and can be used as a preparatory network before launching on Polkadot — though many projects opt to stick with Kusama for their final product.

Kusama benefits from a low barrier to entry for deploying parachains, low bond requirements for validators, and is most commonly used by early-stage startups and for experimentation.

Kusama

Chia Network (XCH) is a layer 1 blockchain that uses its own custom-designed programming language called Chialisp and a novel consensus mechanism called proof-of-space-and-time (PoST). The combination of these two allows the blockchain to use less energy without compromising network security. In contrast to most other blockchains, Chia Network is a public, for-profit, open source company that aspires to become listed on NYSE or NASDAQ. Its blockchain is aimed at enterprise use, which is why Chia Network plans to have XCH on its balance sheet in case of a listing.

Chia Network’s first proof-of-time function was released in 2019, with the first beta version of its blockchain launching in 2020. Chia Network achieved full functionality, including wallet functionality, transactions and smart contracts, with its mainnet launch in 2021.

Neon EVM

Multichain (MULTI), previously known as Anyswap, claims to be the ultimate router for web3 and has positioned itself as an infrastructure developed for arbitrary cross-chain interactions.

As claimed in their official documentation, Multichain offers solutions that enable nearly all blockchains to interconnect – regardless if it is EVM chains (e.g., Avalanche), Layer 2 chains tied to Ethereum (like Polygon), Parachains networks like Moonbeam on Polkadot, and so on.

Multichain is a prominent name in the cross-chain space, with a rapidly growing network of 26 chains, with Total Value Locked (TVL) reaching highs of over $10.45 billion, and a sustained daily volume of over $100 million. However, the onset of the bear market and recent news of Multichain CEO being uncontactable saw TVL dropping to $1.38B.

Multichain

Moonriver is an Ethereum-compatible, smart-contract parachain on Kusama. It is intended to be a companion network to Moonbeam, where it will provide a permanently incentivized canary network. New code will ship to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code will ship to Moonbeam on Polkadot.

It does this by providing a full EVM implementation, a Web3-compatible API, and bridges that connect Moonriver to existing Ethereum networks.

This allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonriver with minimal changes.

Covalent leverages big-data technologies to create meaning from hundreds of billions of data points, delivering actionable insights to investors and allowing developers to allocate resources to higher-utility goals within their organization.

Instead of painstakingly sourcing data from a small handful of chains, Covalent aggregates information from across dozens of sources including nodes, chains and data feeds. The Covalent API then sources end-users with individualized data by wallet, including current and historical investment performance across all types of digital assets. Most importantly, Covalent returns this data in a rapid and consistent manner, incorporating all relevant data within one API interface.

Having achieved product-market fit, we are now planning to execute the next phase of Covalent, which is a progressive decentralization that will enable the Covalent Network to be owned and operated by its users. Of course, a critical piece to this is CQT.

CQT is the native token of the Covalent Network. It has three primary purposes:

CQT is a governance token, whereby token holders vote on proposals to change the system parameters.

CQT is a staking asset. Validators will earn fees for answering queries.

CQT is a network access token that fulfills data queries for users of the API.

Developer resources include:

Covalent Knowledge Base for extensive guides on how to use the Covalent API. 

Covalent API Documentation.

Osmosis (OSMO) is a decentralized exchange (DEX) for Cosmos, an ecosystem of sovereign, interoperable blockchains all connected trustlessly over IBC, the Inter-Blockchain Communication Protocol. Osmosis also offers non-IBC assets bridged from the Ethereum and Polkadot ecosystems. Originally based on Balancer-style pools, Osmosis is moving to a more sustainable concentrated liquidity model that provides a superior trading and liquidity provision experience.

As an appchain DEX, Osmosis has greater control over the full blockchain stack than DEXs that must follow the code of a parent chain. This fine-grained control has enabled, for example, the development of Superfluid Staking, an improvement to Proof-of-Stake security. Superfluid staking allows the underlying OSMO in an LP position to add to chain security and earn staking rewards for doing so. The customizability of appchains also allows for the development of a transaction mempool shielded with threshold encryption, which will greatly reduce harmful MEV on Osmosis.

Osmosis's vision is to build a cross-chain native DEX and trading suite that connects all chains over IBC, including Ethereum and Bitcoin. To build out the trading functionalities, Osmosis has invited external developers to create a bespoke DEX ecosystem that includes lending, credit, margin, fiat on-ramps, Defi strategy vaults, NFTs, stablecoins, and more – all the functionalities of a centralized exchange and more, plus the trust-minimization of decentralized finance.

Ethereum-based DYDX ($ethDYDX) is a governance token that allows the dYdX community to truly govern the dYdX Layer 2 Protocol built on Ethereum ("dYdX v3"). ethDYDX is currently undergoing a migration from Ethereum to the dYdX Chain. More information is available here. If you want to migrate ethDYDX to dYdX Chain DYDX, to enable staking, security and governance of the dYdX Chain you can follow the how-to-bridge guide here.

If you want to read about the new token utility for dYdX Chain DYDX you can read the blog here

ethDYDX (dYdX) is the governance token for the layer 2 protocol built on Ethereum. By enabling shared control of dYdX v3, ethDYDX allows traders, liquidity providers, and partners of dYdX to work collectively towards an enhanced dYdX v3.

Built on StarkWare’s StarkEx scalability engine, layer 2 is used for trading of cross-margined perpetuals on the platform. The scaling solution allows dYdX to increase transaction speed, eliminate gas costs, reduce trading fees and lower​​ minimum trade sizes on the protocol.

A total of 1,000,000,000 ethDYDX have been minted, and started to become accessible over five (5) years, on August 3rd, 2021, at 15:00:00 UTC.
