The XMScript

The XMScript is a JSON script that dictates how a cross chain should be broadcasted to another blockchain from a DEMOS node. The XMScript contains the following information:

Blockchain identifier .eg. eth,solana, xrpl, etc
Subchain identifier .eg. sepolia
Signed payload
Task parameters
Task type. eg. pay, contract_read
RPC URL (Optional)

A single XMScript can contain multiple blockchain payloads. The order of execution of these payloads is controlled using an operation_order list. Here’s an example XMScript

import { XMScript } from "@kynesyslabs/demosdk/types"

const xmscript: XMScript = {
    operations: {
        "0": {
            chain: "eth",
            is_evm: true,
            rpc: null,
            subchain: "sepolia",
            task: {
                params: null,
                signedPayloads: ["0x02f87583aa36a76a84237ef1..."],
                type: "pay",
            },
        },
    },
    operations_order: ["0"],
}
