warp10-ext-web3

The Web 3 WarpScript extension adds functions to interact with Ethereum compatible blockchains. This includes generating and signing transactions, both simple value transfer and smart contract calls, sending transactions to Ethereum nodes, and decoding return values and logs from transaction receipts.

As examples, this extension enables Warp 10 to act as an oracle or interact with DeFi protocols by acting as an arbitrageur or proceeding with liquidations. These examples are only a few of those made possible by those functions.
