Stellar advances with Golang SDK, stablecoin tests, and Protocol 25 upgrade

What shipped

Welcome to the latest update from the world of blockchain and cryptocurrencies as of December 2, 2025. Today, we’re focusing on some exciting developments primarily around the Stellar network and other blockchain projects that are making waves. Here’s a quick overview of the key news:

Stellar launched a new Golang SDK to help developers build applications more easily on its blockchain.
A U.S. bank is testing custom stablecoin issuance on the Stellar network, which points to growing interest from traditional finance in blockchain technology.
Stellar released a detailed guide on its Protocol 25 upgrade, an important technical update to improve network performance and security.
Chainlink shared insights on compliance in the future of finance and how blockchain improves cross-border payments, highlighting the growing role of blockchain in global finance.
Unlimit introduced Stable.com, a decentralized clearing house designed specifically for stablecoins, aiming to boost stability and trust in crypto markets.
Research from Anthropic shows AI agents are getting closer to real-world attacks on DeFi (decentralized finance) platforms, emphasizing the importance of security in blockchain applications.

Why it matters

These updates highlight several important trends in the blockchain space that matter to investors, developers, and anyone curious about this technology:

Improved developer tools: The new Golang SDK from Stellar means it’s easier and faster for programmers to create applications on Stellar’s blockchain. SDK stands for “Software Development Kit,” a collection of tools and code that helps developers build software without starting from scratch.
Traditional finance embracing blockchain: The U.S. bank testing stablecoin issuance on Stellar is a big deal. Stablecoins are cryptocurrencies designed to maintain a stable value, often pegged to a currency like the U.S. dollar. Banks using them could mean faster, cheaper, and more transparent transactions.
Network upgrades keep systems secure and efficient: Protocol upgrades like Stellar’s Protocol 25 improve how the blockchain runs, making transactions quicker and safer. This keeps users confident and helps the network grow sustainably.
Focus on compliance and security: As blockchain becomes part of mainstream finance, compliance means following laws and regulations to keep things safe and fair. Chainlink’s focus on compliance and security insights helps the ecosystem mature and gain trust.
Innovation in stablecoins: Unlimit’s Stable.com platform is an exciting development. A decentralized clearing house is like a trusted middleman that helps different stablecoins settle transactions smoothly. This could reduce risks and increase adoption of stablecoins worldwide.
Security challenges ahead: The report on AI agents potentially attacking DeFi platforms is a reminder that as technology advances, so do the risks. It highlights the need for continuous improvements in blockchain security.

Builders’ corner

If you’re a developer or someone interested in building with blockchain technology, there’s plenty to explore right now:

Try out the new Golang Stellar SDK: This SDK is designed to make building on Stellar more accessible, especially if you prefer the Go programming language, which is known for its speed and simplicity. You can find the SDK and documentation on Stellar’s official site.
Explore stablecoin projects: With banks experimenting with stablecoins, it’s a good time to learn how stablecoins work and how you might contribute to projects like custom issuance or decentralized finance applications.
Understand protocol upgrades: The Stellar Protocol 25 upgrade guide is a great resource to understand how blockchain networks evolve. Following such upgrades can help you stay ahead and build compatible applications.
Focus on compliance and security: Learn about regulatory requirements and security best practices. Chainlink’s blog posts provide useful insights into how blockchains are adapting to meet these challenges.
Watch for AI and security developments: With AI increasingly involved in blockchain, both as a tool and a potential threat, staying informed about security research will be crucial for developers and investors alike.

Quick prices

Here’s a snapshot of some popular cryptocurrencies as of early December 2025:

Bitcoin (BTC): $86,880 USD, up slightly by about 0.15% in the last 24 hours. Bitcoin remains the most well-known and valuable cryptocurrency.
Ethereum (ETH): $2,805.28 USD, down about 1.3% in the last day. Ethereum is famous for its smart contracts and decentralized applications.
Ripple (XRP): $2.02 USD, down about 1.25%. Ripple focuses on fast and low-cost cross-border payments, often working with banks.
Stellar (XLM): $0.23 USD, almost flat with a very small dip. Stellar is known for connecting financial institutions and enabling quick transactions.
Hedera Hashgraph (HBAR): $0.13 USD, down about 1.15%. Hedera uses a different technology called “hashgraph” which offers fast and secure consensus.
Flare Network (FLR): $0.013 USD, down about 4.24%. Flare aims to bring smart contract functionality to other blockchains that don’t natively support it.
XDC Network (XDC): $0.051 USD, down about 0.54%. XDC focuses on enterprise blockchain solutions, especially for trade and finance.

What to watch

Looking ahead, here are some areas to keep an eye on:

Stellar’s growing partnerships: With banks testing stablecoins on Stellar, watch for announcements of new partnerships or real-world use cases that could drive adoption.
Development tools and SDKs: More developer-friendly tools like the Golang SDK can accelerate the creation of new apps and services, boosting network activity.
Security and compliance: As blockchain integrates more with traditional finance, expect tighter regulations and increased focus on security. Projects that adapt well will likely thrive.
Stablecoin innovations: Platforms like Stable.com could transform how stablecoins operate and interact, so keep an eye on their progress and impact.
AI impact on DeFi security: The evolving role of AI in blockchain security is a double-edged sword. Stay informed about new threats and defenses in the space.

TL;DR: Stellar is making big strides with a new Golang SDK and real-world stablecoin testing by a U.S. bank, signaling growing adoption of blockchain in finance. Network upgrades and innovations like Unlimit’s decentralized clearing house for stablecoins show the ecosystem is maturing. While prices are mostly steady with Bitcoin near $87,000, security challenges from AI in DeFi remind us to stay cautious but optimistic about blockchain’s future.
