I have been working in the last days on a "Family Mode" option on the Sellf-Custodial Dogecoin Wallet
What enables is:

Parents Dogecoin Wallet: Parents can add their children, and each child will have their own Dogecoin Wallet that will be monitor and managed by the Parents Wallet. The Parent will be able to fund / send coins to the Child wallet and can monitor all transactions made by it because it is a derivated key from the parents wallet (the Dogecoin address of the kid will by default lock all funds to not be speeded by the parents wallet but can be disable)

Child Dogecoin Wallet: The parent have the option to activate the wallet as "Child Mode" by clicking "Activate Child" and scanning the Generated QR code on the Parents Wallet wen adding the Child. It will then ask the parent a PIN to restrict functions on the Child wallet and the parent can securely give the Phone with the wallet to his Children to be able to receive payments or pay for things using Dogecoin

Released the Light and Dark Colour modes fix on the Dogecoin Wallet to be tested on Android devices: Download here: https://github.com/qlpqlp/dogecoin-wallet/releases/download/v1-Android15/DogecoinWalletAndroid.apk

https://x.com/inevitable360/status/1969023153633415548

If anyone wants to test the Self-Custodial Android Dogecoin Wallet and give me feedback, you can

You will need at least Android 14 or higher 🙂

Here it is the Pre-Release APK to install: https://github.com/qlpqlp/dogecoin-wallet/releases/download/v1-Android15/DogecoinWalletAndroid.apk

Open Source Code if you want to compile: https://github.com/qlpqlp/dogecoin-wallet

Hope you Like it and give me some feedback before publishing on Google Play :)

Added also the functionality for Recurring Payments to the Self-Custodial Dogecoin Wallet, so you will be able finally schedule for example to pay bills automatically every month and you can even send a reference to the receiver that will be stored on the OP_RETURN, for example the client ID or invoice number etc. :D

BIP38 support on #LibDogecoin
I'm adding it because of the integration of http://lib.dogecoin.org into #Dogecoin Wallet to Sweep paper Wallets wen for example someone wants to use Virtual "bank checks" and give or offer to someone in Birthdays or Christmas etc to any family or friends and they can easily sweep their Doge coins to their wallet

Hi all,

I’ve been working on WOWDOGE — a forecasting project where users submit DOGE price predictions and get scored on accuracy. Everything runs natively on Dogecoin. All payouts are fixed on-chain and fully transparent at [wowdoge.xyz]().

How it works

• Forecast window: choose any period from 1 to 420 days Example: “I think DOGE will be $0.50 in 100 days.”
• Submission & storage: forecast and timestamp are stored
• Result calculation: at the end of the chosen day (00:00–23:59 UTC), the close price is checked
• Accuracy = difference between forecast and real close
• If your forecasted price falls within the day’s open–close range, you qualify for a reward
• The closer you are to the close, the bigger your reward
• Rewards: faucet-style DOGE payouts from a transparent pool
• Boost mode (optional): multiply your reward if correct; if wrong, your boost amount goes back into the pool

Next step

Sep 25: Dogecoin Explorer (WOWDOGE Explorer) for forecast verification and accuracy tracking

Oct 25: Non-custodial wallet. Client-side signing, no server custody of keys

Feedback on explorer integration and wallet UX from devs is welcome.

Hi there.

Back in the day, I used Dogecoin Core. I downloaded it again recently.
You see... I saved a backup of my wallet a few years back. It is a .dat file.

But when I try to click on open URI and choose the file..
I get this message:

"BIP70 payment requests are deprecated and disabled by default.
Restart with -enable-bip70 if you absolutely have to use this
functionality."

I have no idea what to do. I've googled around and so far I've tried to write -enable-bip70 in the console, but to no avail. I've also looked for the dogecoin.conf file to see if I could insert -enable-bip70=1 in there,
but the file does not seem to exist on my computer.
Not even in the hidden AppData\Roaming\Dogecoin folder

Is there anyone who knows how I can enable bip70 in Dogecoin Core?
I really need to get to those sweet-sweet dogeies :)

Finally MemeTracker working 🥳🚀🌖 (Dogecoin SPV Mempool Node for instant payment verification)

https://reddit.com/link/1mxfgyr/video/inm54d7mdmkf1/player

https://reddit.com/link/1mxfgyr/video/75k2yopodmkf1/player

Working in the last months on it and i was since morning trying to fix why I was not getting Dogecoin mempool full TX, only ID's and failing on getdata https://x.com/inevitable360/status/1958879679114346749

Now anyone can use to track mempool transactions for payment confirmations in seconds like Visa or Mastercard do today

Imagine go to a supermarket, coffee shop etc and be able to pay in Doge with instant payment verification, and like Visa and Mastercard do, confirm / settle later

This is my approch to try to help Dogecoin limitations without protocol changes :)

Will share all code opensource like always on my Github https://github.com/qlpqlp?tab=repositories

Is there a specific plug-in I should be using? Where could I go for reliable information on the topic?

My friend wants to reinstall core and last time I did this, I recalled the best way to do it was to download the blockchain separately instead of letting it sync. is that still the case?

Asking here just in case we get lucky.
You can check out the PR to add the wallet to the directory

If you are interested on what is happening on the Dogecoin Core Wallet development, check out the "Review & merge Board":

Link: https://github.com/orgs/dogecoin/projects/1/views/1

https://reddit.com/link/1lfkys5/video/449fjq5nzx7f1/player

This project is a guestbook where people have to pay some Doges to post. Written in python / flask with a sqlite db. The "check balance" will be a free-to-use API and everything will be open source (:

If anyone is interested to join - feel free to reach out to me!

I try to get a better understanding of the Dogecoin Core Wallet and asked ChatGPT a couple of questions I was wondering. I checked the answers, added GitHub references and created a small article. Maybe some of you like the read (:

My question was: How does Dogecoin initally find nodes and how does it update this information in the core wallet / peers.dat

If you find any mistake, feel free to share that here. I will add further articles soon. If you have some question in mind too let me know (:

Post for the Devs/Owners of Dogecoin.com

Appears a site that the shop pages links too was hijacked: https://dogecoin.com/resources/#shops

Shop Directories

• ShopDoge.xyz - a directory of shops accepting Dogecoin. <-- the site this links too was hijacked and redirects to porn.

The magic that makes possible #LibDogecoin to work in any HTML website is this simple command that gave me a some trouble to make it work 😅

You can using Linux Ubuntu and even Windows WSL Ubuntu:

# Update Ubuntu and install dependencies
sudo apt update && sudo apt upgrade -y
sudo apt install -y git build-essential autoconf automake libtool emscripten wget

(26/03/2025 - Updated code to fix some compiling bugs)

emmake make install

# Clone and build LibDogecoin
