Hi there XUMM devs, I'm new to XRPL and XUMM networks and I'm going to launch an NFT collection of 5000 arts on XRPL networks. Can you guys please point me in the right direction on how I can set up a XUMM wallet "Connet" on my minting website and how can I send transactions to buyers? I'm a solidity dev so this is new to me. All help will be appreciated. Thank you

As xumm is developed for the xrpl, I am wondering if you could use the xumm sdk aswell for the federated side chains, so let’s Imagen there is a cbdc on a sidechain and I want the User to make a cross chain transaction, can we use the sdk for that ?

Hello friends I'm from xrpdomains.xyz, I used the view NFTs function on Xumm wallet and found that currently URIs don't support non-ascii characters and emoji, it won't read it and says no name found. Hope you can help update it. xrp.cafe can display it very well. xrp.cafe: https://xrp.cafe/nft/00080000413DEC6E282BBCEA55B71140D0CB35F01673BBE051E86273000000D8 URI: https://mainnet.xrpdomains.xyz/api/nftdomains/metadata/we%E2%9D%A4%EF%B8%8Fxrp.xrp Thanks so much

Hey there, We've been using session cookies to hold onto the wallet address, signing in with the xumm sdk. I'm not sure how long ago, but it seems the cookies are being dropped, and our session is coming back undefined. Any idea why that would be? Is this still the Xumm app repo? I looked at the WebView and couldn't find any reason it would drop the cookies: https://github.com/XRPL-Labs/XUMM-App/blob/8e6e795648b97d0067380baa43bedea9e4b5ea61/src/screens/Modal/XAppBrowser/XAppBrowserModal.tsx#L515 react-native-webview allows third party cookies by default. Thanks!

This link ( https://xrpl.org/account_info.html ) gave me info about XRP. Is there any api endpoint for getting the RPR balance of Xumm wallet?

Is there a way to get info related to which accounts are in the Xumm users address book?

here is an example of how im using xrpl to batchminting nfts, 100+ nfts at once. how can i do the same with xumm without having the user to sign the tx 100 times. <https://xrpl.org/batch-minting.html> ```javascript const mintBatch = async (account,tickets) => { try { const mintedTxs = []; for (let i = 0; i < tickets.length; i++) { const transactionBlob = { TransactionType: "NFTokenMint", Account: account.classicAddress, URI: xrpl.convertStringToHex("some url" + i), Flags: parseInt("9"), TransferFee: 100, Sequence: 0, TicketSequence: tickets[i], LastLedgerSequence: null, NFTokenTaxon: 0, }; mintedTxs.push(client.submit(transactionBlob, { wallet: account })); } Promise.all(mintedTxs) .then(async (txs) => { console.log(txs); return "done!"; }) .catch((err) => { console.log(err); }); ```

I Struggle to mint an NFT and get this masseage. Any help please
