RenBridge enables the simple wrapping of digital assets on different blockchains. RenBridge allows users to take BTC and put it on Ethereum, as an ERC-20 called renBTC. Using RenVM, a universal translator, it converts digital assets to the format needed by its destination chain. RenVM takes BTC, holds it, and then converts it to an ERC-20 with a 1:1 ratio to ensure your renBTC is always backed by the same amount of BTC. RenVM holds on to your assets when they are on other blockchains. RenVM is new technology, and security audits don't completely eliminate risks. Please don't supply assets you can't afford to lose!

The Avalanche Bridge (AB) can be used to transfer ERC20 tokens from Ethereum to Avalanche's C-Chain and vice versa. The next generation Avalanche Bridge (AB) replaces the existing Avalanche-Ethereum Bridge (AEB) and provides a significantly better user experience with stronger security, faster finality, and dramatically lower fees. It is estimated to be 5x cheaper than the AEB and a better user experience than any bridges launched to-date. There are also other bridges that are not affiliated with or created by Ava Labs. You can also use centralized exchanges to send AVAX to your wallet on Avalanche, and then swap AVAX for other assets using a decentralized exchange. Avalanche consensus is well suited for building DeFi applications due to its scalability features, particularly its high throughput and near-instant finality. The deployment of the Aave Protocol on Avalanche will allow users to leverage low transaction costs without compromising the security of the network.

Before completing decentralized crosschain transactions using WanBridge Web, you need to ensure you have access to the correct wallet(s). You must have wallets for each network involved in the crosschain transaction. In other words, if you are moving $BTC from Bitcoin to Ethereum, you need to use Bitcoin and Ethereum wallets. Similarly, if you are moving $LTC from Wanchain to Moonriver, you need Wanchain- and Moonriver-compatible wallets. Click “Select asset please” on the left side of the terminal. Select the asset you want to move crosschain from one blockchain network to another. Click “Select From Chain” and select the origin chain. Click “Select To Chain” and select the destination chain. Click “Connect to Wallet” in the top right corner of the window. When connecting Metamask for the first time, you will need to click connect in the Metamask pop-up window. Your Ethereum wallet address will now be connected to WanBridge Web. Your ETH balance should also be visible.

RELAY is a multi cross-chain platform developed to bring BaaS (Bridging as a Service) to help the often fragmented DeFi liquidity space. What is really unique to our bridge is that when a new ecosystem is created, our bridge connects that asset and ecosystem to all the other ones we support. At launch we currently support bridging to Ethereum, BSC, Avalanche, Polygon (Matic), and Heco — with more coming soon. Relay's bridges were first to introduce the bridge gas token faucet to Defi where the bridge itself airdrops the native gas token to new users to reduce friction for people starting out on new chains. We have built many products during our tenor in DLT but during the last 6 months and after completing the first brdige to Avalanche we realized that safe and secure briding will be a corner stone of DeFi and we dropped everything to bring this reality to our users.

Horizon is a cross-chain bridge that allows exchange of crypto assets (e.g., fungible/non-fungible tokens, stablecoins) between Ethereum, Binance Smart Chain and Harmony blockchains. Horizon’s main purpose is to enable transfer of assets from Ethereum (or Binance Smart Chain) to Harmony. Users holding assets on Ethereum (or Binance Smart Chain) can exchange them to corresponding assets on Harmony (1:1). Horizon also allows redemption of the exchanged assets back to the user's Ethereum (or Binance Smart Chain) account at any time. A pool of validators that listens to events on both Ethereum and Harmony bridge smart contracts. When a token lock action is detected on Ethereum blockchain, the pool of validators validates it and relays the finalized information to the Harmony blockchain: here, the same amount of a bridged token is minted. On the opposite, when a bridged token burn is detected on Harmony blockchain, the pool of validators validates it and relays the finalized information.

Hop is a scalable rollup-to-rollup general token bridge. It allows users to send tokens from one rollup or sidechain to another almost immediately without having to wait for the networks challenge period. It works by involving market makers (referred to as Bonder) who front the liquidity at the destination chain in exchange for a small fee. This credit is extended by the Bonder in form of hTokens which are then swapped for their native token counterpart in an AMM. It's hard to quantify security of a protocol but the core team of Hop has worked diligently on the protocol for over one year before releasing it to the public. The Hop core team has extensive experience in smart contract development. Before building Hop they were working as smart contract auditors for several years auditing popular protocols such as Augur, OpenZeppelin, Decentraland and DyDx and consequently built one of the first smart contract wallets in the Ethereum space called Authereum.

Frax is open-source, permissionless, and entirely on-chain – currently implemented on Ethereum and other chains. The end goal of the Frax protocol is to provide a highly scalable, decentralized, algorithmic money in place of fixed-supply digital assets like BTC. Frax is a new paradigm in stablecoin design. Many stablecoin protocols have entirely embraced one spectrum of design (entirely collateralized) or the other extreme (entirely algorithmic with no backing). Collateralized stablecoins either have custodial risk or require on-chain overcollateralization. Frax is the first and only stablecoin with parts of its supply backed by collateral and parts of the supply algorithmic. This means FRAX is the first stablecoin to have part of its supply floating/unbacked.

Deri Protocol is the DeFi way to trade derivatives: to hedge, to speculate, to arbitrage, all on-chain. With Deri Protocol, trades are executed under AMM paradigm and positions are tokenized as NFTs, highly composable with other DeFi projects. Having provided an on-chain mechanism to exchange risk exposures precisely and capital-efficiently, Deri Protocol has minted one of the most important blocks of the DeFi infrastructure. As the solution to decentralized derivative exchange, Deri Protocol is designed with all the defining features of DeFi and financial derivatives in its nature. Deri Protocol is a group of smart contracts deployed on the Ethereum blockchain, where the exchange of risk exposures takes place completely on-chain. Anybody can launch a pool with any base token (but usually with a stablecoin, e.g. USDT or DAI). That is, the protocol does not enforce any specific “in-house chip”.
