1/🧵 Ein kurzer Einblick in @gemwallet_app, die #opensource, "non-custodial" #XRPL Web-#Wallet für das #Web3.0 und "#Ripple XRPL Grants Wave 3" Gewinner Source: https://xrpl.org/blog/2022/gemwallet.html
2/ Ähnlich wie bei MetaMask ist #GemWallet eine "Browser-Extension"-App für den einfachen Umgang im #Web3, jedoch nativ auf dem #XRPL.

Funktionen sind z.B.:
• GemWallet #API (Brücke zwischen Websites und der Browser-Extension)
• Bezahlungen
• #Private/#Pubkey-Generierungen Source: https://gemwallet.app/
3/ 🛠️ Möchte man also per #API (NPM/Node.js oder CDN/Browser) eine Brücke zwischen dem #XRPL und seiner eigenen #Web3-#dApp herstellen, bietet #GemWallet die dafür notwendigen Tools und Werkzeuge.

github.com/GemWallet/gemw…
4/ 😅 Aber was ist überhaupt "#Web3.0"?

Kurz gesagt reden wir von "#Web3", wenn das Fundament des klassischen #Web2 (#WWW) durch #Blockchain-Technologie geupgradet und dezentralisiert wird

Beispiele sind:
• Storage/Hosting: #IPFS /#ICP
• Dezentrale ID / "Login via #Wallet" Source: https://assets.weforum.org/article/image/responsive_
5/ 💡 Showcase / Demo-Transaktion

Florian Bouron zeigt auf seiner #Devnet E-Commerce Test-Webseite, wie der Umgang im #XRPL #Web3-Ökosystem aussehen könnte

Weitere Beispiele könnten Spenden-Webseiten oder zukünftig auch der Handel mit #NFTs sein

6/ 👉 Ablauf einer #Web3 #XRPL Authentifizierung

• Persö. Details veröffentlichen nicht notwendig
• Login mit dem #PublicKey & der Adresse (#Wallet)
• ID / Besitz der Keys beweisen (TX signieren) und Zugangs-Token aka. [J]SON [W]eb [T]oken erhalten.

7/ 👉 Unterstützte Geräte

Derzeit werden nur die auf Chromium basierenden Desktop Browser unterstützt. (Mehr ist jedoch geplant)

✅ Chrome, Brave, Microsoft Edge
❌ Firefox, mobile iOS oder Android Source: https://davescomputertips.com/wp-content/uploads/202
8/ 👉 Privatsphäre des eigenen #XRPL Accounts

Sobald eine Webseite für eine Transaktion die Account-Adresse (+#PubKey) auslesen möchte, muss das Leserecht hierfür vorher erst von einem selbst, via Konfirmations-Dialog, autorisiert werden

Hierfür fragt die Wallet ein Passwort ab Source: https://www.youtube.com/watch?v=20EjOtXnICY
9/ ⚠️ Hinweis ⚠️

Wie bei jeder Wallet, jeder App, jedem #Exchange und auch jeder Software, die die Verwahrung der #Keys übernimmt, muss sichergestellt sein, dass der Code keinen (un-)gewollten Exploit zulässt

Entscheidet daher selbst, ob ihr dem #opensource Code vertraut 😊 Source: https://gemwallet.app/
10/ 👉 Zukunftspläne und Entwicklungen

• #NFT Support
• #XRPL #SmartContracts (aka. Hooks)
• Interoperabilität (aka. [#EVM-]#Sidechains)

[1/🧵] Crashcourse XRP Ledger Permissioned DEX!

With the introduction of credentials, permissioned domains and permissioned DEXs the XRPL will evolve into a completely new type of beast!

No tech depth ahead, just the basics. 👇 Source: @krippenreiter
[2/21] — The Identity Tech Stack —

For pDEXs to exist and work as intended, three different features need to be active on the XRP Ledger:

🔸 (optional) DID ✅
🔸 Credentials ✅
🔸 Permissioned Domains ⏸️
🔸 Permissioned DEX ⏸️ Source: @krippenreiter
[3/21] — 1⃣ TL;DR —

The TL;DR is that pDomains are restricted environments on the XRPL that let users with permission use certain functions within the domain, like a DEX, in case the user owns the correct credentials. 🧐

Too much jargon, I know. 😅 Source: https://xrpl.org/docs/concepts/tokens/decentralized-exchange/permissioned-dexes#key-roles-in-a-permissioned-dex

[1/🧵] The bullrun seems to be just around the corner, and everyone is teasing us with yield and XRPFi protocols. 🧐

Regardless of whether you decide to hold or sell...

Let's take a look at "Lending" and check if it's worth it. 👇 Source: https://finematics.com/lending-and-borrowing-in-defi-explained/
[2/14] — 1⃣ Money Markets —

Before we do just that, let's quickly clarify a specific word first.

Behind the terms "Lending" and "Borrowing" actually hides another term that you will see from time to time:

🔸 Money Markets Source: https://chain.link/education-hub/decentralized-money-markets
[3/14] — 2⃣ Money Markets —

Besides AMMs, lending is currently the most important pillar for on-chain DeFi, as it removes the middleman in the pooling, management, and lending of funds.

The goal? 🤨

Positive yield or in other words, interest on the liquidity you provide. Source: https://www.investopedia.com/terms/i/interest.asp

[1/🧵] A MASSIVE attack on the JavaScript ecosystem is currently underway. ☹️

Since JavaScript is at the heart of what we use every day to browse the internet, you MUST be extra vigilant.

Let's take a look at a possible solution for the XRP ecosystem. 👇🧵 Source: https://xrplfirewall.com
[2/13] — 1⃣ First things first —

Although the entire JavaScript ecosystem is at risk, the malware appears to be targeting only a few blockchain ecosystems, based on the addresses it uses to steal funds:

‼️ At risk 👇 Source: https://jdstaerk.substack.com/p/we-just-found-malicious-code-in-the
[3/13] — 2⃣ First things first —

The reason this is such a big deal is because of the sheer volume of weekly downloads of the maliciously patched packages. Source: https://jdstaerk.substack.com/p/we-just-found-malicious-code-in-the

[1/🧵] You've probably heard about new yield opportunities with XRP that promise a return of around 20% APY. 🧐

How much truth is there to this, and what happens if you actually connect to @moremarketsxyz and deposit funds? 👇
[2/14] — 1⃣ First things first —

👉 I want you to repeat after me:

"I will not deposit all my XRP into completely new DeFi protocols right after their launch, no matter the yield" Source: @krippenreiter
[3/14] — 2⃣ First things first —

When you join any DeFi protocol, start with very small amounts (e.g., 1 XRP) to get a feel for how things work, and try to regularly withdraw everything to test whether you can realize your profits with the protocol or not. 👍 Source: https://app.moremarkets.xyz

[1/🧵] What's still upcoming and in the pipeline for the XRP Ledger? 🧐

My attempt to summarize what the brilliant @aanchalmalhotre "casually" laid out in a 25-minute talk at XRPL Apex this year. 👇 Source: https://www.youtube.com/watch?v=UzbHAbBtLXQ
[2/15] — 1⃣ Key-Challenges —

Privacy and compliance are at odds with each other, and balance is key.

A lot of what the TradFi world is used to and expects still doesn't exist or is purposefully different in blockchains, like transparent transactions or low confidentiality. Source: https://www.youtube.com/watch?v=UzbHAbBtLXQ
[3/15] — 2⃣ Key-Challenges —

Institutions also expect their on-chain operations, aka transactions, to be highly customizable and controllable because of factors like internal risk management.

👉 They expect the XRPL to be programmable for their dedicated policies. Source: https://www.youtube.com/watch?v=UzbHAbBtLXQ

[1/🧵] XRP Ledger ✖ Axelar ✖ XRPL EVM Sidechain ✖ Squid ‼️

With all these new integrations and partnerships, I bet you are pretty much overwhelmed by all the alien-like jargon. 🤨

A little vocabulary crash course ahead 👇 Source: https://axelarscan.io
[2/20] — 1⃣ Overview —

What just happened today is nothing less than the complete onboarding of the XRPL to the vast and entire web3 blockchain ecosystem (+ Bridging protocols and available liquidity).

👉 All via the XRPLEVM sidechain, Axelar and @squidrouter. Source: https://axelarscan.io
[3/20] — 2⃣ Overview —

What does this mean in practice? 🧐
🔸 New tokens on the XRPL DEX (bridged by @axelar)
🔸 Literal (and easy) any-to-any swaps (via Squid)
🔸 Liquidity from the entire web3 ecosystem (via CORAL)
🔸 Bridged XRP accessible on 80+ chains (through XRPLEVM) Source: @squidrouter
