#technology #cryptocurrency 1/ Sharing insights into crypto cross-chain technology, focusing on CCIP, CCTP, and Wormhole, and their roles in blockchain interoperability. 2/ CCIP (Cross-Chain Interoperability Protocol) "at a glance": it is developed by Chainlink @chainlink and it enables communication and data sharing between different blockchains, suitable for decentralized apps that operate across multiple chains. https://chain.link/cross-chain 3/ CCTP (Cross-Chain Transfer Protocol) "at a glance": it is developed by Circle @circle and is designed for the secure and efficient transfer of tokens across different blockchains, beneficial for users operating on multiple chains. https://www.circle.com/en/cross-chain-transfer-protocol 4/ Wormhole @wormholecrypto "at a glance": it serves as a bridge between blockchains, facilitating asset transfers and cross-chain information sharing, useful for multi-chain applications. https://wormhole.com/ 5/ CCIP: Focus on interoperability and decentralized application support. One of the most notable use cases is the Cross-Chain Settlement of Tokenized Assets in collaboration with Australia and New Zealand Banking Group Limited (ANZ), BNP Paribas, BNY Mellon, Citi, Clearstream, Euroclear, Lloyds Banking Group, SIX Digital Exchange (SDX) and The Depository Trust & Clearing Corporation. https://chain.link/resources/cross-chain-tokenized-asset-settlement 6/ CCIP: In August 2023, [[Society for Worldwide Interbank Financial Telecommunication (SWIFT)]] announced "Successful blockchain experiments" in a report describing how collaboration was attempted in joining strengths with several financial institutions to transfer tokenised assets across multiple public and private blockchains. The initiative used Chainlink as an enterprise abstraction layer to connect the Swift network to the Ethereum Sepolia network, while Chainlink’s Cross-Chain Interoperability Protocol (CCIP) enabled complete interoperability between the source and destination blockchains. https://www.swift.com/news-events/news/successful-blockchain-experiments-unlock-potential-tokenisation 7/ CCIP: In the DeFi space, the most notable use cases and integrations are with AAVE, Synthetix, LIDO, Trader Joe. https://chain.link/use-cases/defi 8/ CCTP: Given the nature of Circle, it specializes in asset transfers and liquidity movement. Beside the usual suspect USDC, CCTP offers settlement in EURC (the less popular European sister stablecoin). The CCTP Circle Mint solutions are tested and/or embraced by @Visa , @MoneyGram , @stripe in the TradFi world, as well as @okx and @Bybit_Official in #crypto https://www.circle.com/en/circle-mint 9/ CCTP: Sits at the back of the Aggregation Services on the one hand and the Cross-Chain Messaging Platforms on the other hand. Apps, Wallets, Bridges, Custodians are built on top of the infrastructure that serves the End Users. CCTP uses a programmatic burning and minting. The process is simple: 1/ The app initiate the transfer and burn USDC on the source chain, 2/ Circle fetches the attestation that confirms the burn event on the source chain providing the authorization to mint and 3/ the transfer is completed by minting the equivalent amount of USDC in the destination blockchain. https://www.circle.com/en/cross-chain-transfer-protocol 10/ CCTP: Offers solid integration with the most popular wallets, supporting METAMASK, OKX and XDEFI. To make the life of developers easier, CCTP is directly integrated with Wormhole SDK connection to Circle, to transfer native USDC between Ethereum and Avalanche. https://wormhole.com/native-usdc-demo/ 11/ Wormhole: Enables asset transfers and smart contract integration. Serves as a bridge between blockchains, facilitating asset transfers and cross-chain information sharing, useful for multi-chain applications. It is ideal for complex multi-chain interactions. Wormhole counts 19 validator nodes and boost solid security by transparently sharing the auditing reports. https://github.com/wormhole-foundation/wormhole-audits 12/ Wormhole: An anti-maxi initiative in partnership with Borderless Capital, Algorand Foundation, Solana, Polygon Labs has made available a $50M fund for builders interested in getting their hands dirty with #wormhole technology by building #web3 apps, dapps, tools and infrastructure. In addition there is a 12-week accelerator program starting this month run by Outlier Ventures with support to the participating projects with up to $200K USD in funding. https://wormhole.com/programs/ 13/ Wormhole: It is fully open source and community driven. Wormhole-connect is available on Github: https://github.com/wormhole-foundation/wormhole-connect 14/ As the industry evolves there is no such a thing as one size fits all. While CCIP is clearly aiming to become the de-facto enterprise solution and Wormhole is possible already the standard for crypto native project, CCTP sits just in between for its ability to bring to the table the second most popular stablecoin in the market and the most used one in DeFi. Depending on the project's need, each solution might bring different strengths. A combination of all 3 solution is a killer combo.
