etchRune

etchRune(config, params): Promise<{ etchingTx: string; fundingTx: string; revealTx: string; }>

Etches (mints) a rune on Bitcoin. The rune will be etched and revealed in the consecutive transactions. This function creates the etching, funding, and reveal transactions. The transactions won't be broadcasted. Once the transactions are created, you can broadcast them using the broadcastTransaction function in the following order: funding, etching, reveal.

Import

import { etchRune } from "@midl/core";

Example

import { etchRune } from "@midl/core";
import { broadcastTransaction } from "@midl/core";

const etching = await etchRune(config, {
    name: "RUNE•NAME",
    receiver: "bc1q...",
    amount: 100,
 ...
});

const fundingTxHash = await broadcastTransaction(config, etching.fundingTx);
const etchingTxHash = await broadcastTransaction(config, etching.etchingTx);
const revealTxHash = await broadcastTransaction(config, etching.revealTx);

console.log(fundingTxHash, etchingTxHash, revealTxHash);
