So, what is 'Axelar ($AXL)' that got listed on Upbit? Axelar is a cross-chain infrastructure that connects various blockchains to securely transfer assets and messages. Those who have studied XRP a bit (which I doubt many have) would know that XRP also includes ISO 20022-based messages for remittances or payment instructions between financial institutions. (e.g., who the sender is, how much the amount is, when the remittance occurred, etc.) So, what does the 'message' sent by Axelar mean? It refers to messages that execute smart contracts. "I'm going to send this to Pano, and once the remittance is complete, buy as many NFTs as possible with this amount." or "Once 1 ETH is sent to Joshiker's wallet, swap it for Bera and deposit it in DeFi," is the kind of messaging technology that contains "smart contracts." As you know, Ethereum is developed in Solidity, Solana in Rust, Bitcoin and XRP in C++, Algorand in Golang, Aptos and Sui in Move, etc... Blockchains are developed in different languages and structures. Therefore, Axelar generates neutral messages in JSON format, and local interpreters deployed on each chain interpret and execute them. In my opinion, this is a technology that provides convenience to blockchain financially illiterate individuals, and it will play a role in creating liquidity (not supply) that is essential for the economy to function in the AI era and the multi-blockchain era, rather than just moving assets. Ultimately, I think it's the cornerstone of a stage where you can send messages in natural language and have them executed.
