runes_estimateMint

Use the runes_estimateMint method to estimate the cost of a Rune mint order for your user, before executing it.

You can specify the characteristics of the Runes mint order you wish to estimate, by passing an EstimateMintParams object to the method, with the below properties:

EstimateMintParams	Description
runeName	a string representing the name of the Rune to mint
repeats	a number representing the number of mint transactions to create. Every mint transaction creates a fixed amount of new units of a rune, you can use repeats to mint a multiple of that amount. ℹ️ Note that there is a 23 repeat limit per order due to transaction chaining restrictions on the Bitcoin blockchain.
destinationAddress	The Bitcoin address to which the minted runes should be allocated. ℹ️If minting Runes for your user, you can fetch their wallet addresses with the getAccounts method. ⚠️ We recommend managing runes holdings on taproot/ordinal addresses.
feeRate	a number representing the desired fee rate to set for the Rune mint transaction(s), in sats per vbytes
appServiceFee (ℹ️ optional)	a number representing the sats value of the fee to charge your user for your service.
appServiceFeeAddress (ℹ️ optional)	a string representing the Bitcoin address which will receive the appServiceFee, if a fee is specified
network (ℹ️ optional)	a string representing the Bitcoin network to use for the mint runes transactions: 'Mainnet' or 'Testnet'

import { Wallet } from "sats-connect";

    const response = await Wallet.request('runes_estimateMint', {
      destinationAddress: ordinalsAddress,
      feeRate: +feeRate,
      repeats: +repeats,
      runeName: runeName,
    });

    if (response.status === 'success') {
      setTotalCost(response.result.totalCost);
      setTotalSize(response.result.totalSize);
    } else {
      console.error(response.error);
      alert('Error Fetching Estimate. See console for details.');
    }

The runes_estimateMint method will not trigger any mint operation or prompt your user to sign any transaction. It will return an EstimateMintResponse object, intended for you and your user to anticipate the mint costs and their breakdown:

EstimateMintResponse property	Description
totalSize	a number representing the total size of the mint transaction(s), in vbytes
totalCost	a number representing the total cost of the mint transaction(s) in sats
costBreakdown	An object representing the cost breakdown of the mint transaction(s), with the below properties: postage a number representing the total size of the Rune UTXOs minted, in sats networkFee a number representing the total network fee for the mint transaction(s), in sats serviceFee a number representing the total Sats Connect fee for processing the mint order, in sats appServiceFee a number representing the optional service fee your app charges the user for the mint order
