šŸ’„Protocol 20 and Smart Contracts Are Live on MainnetšŸ’„
February 20, 2024

On Feb. 20, Stellar network validators voted to upgrade Mainnet to Protocol 20, kicking off a new era for the Stellar smart contracts tech stack, which delivers a secure, batteries-included developer experience built to scale and for real-world use.

Getting to this moment has been an incredible journey. For the last two years, the Stellar Development Foundation (SDF) and the Stellar community have discussed, designed, and built new functionality transforming the Stellar network. Together, we iterated over ten releases in the open, designed novel concepts aimed at solving some of blockchain's biggest unsolved problems like state bloat, committed hundreds of thousands of lines of code, deployed 160+ projects on Testnet and awarded tens of millions worth of XLM through 24 rounds of the Stellar Community FundĀ to support developers and projects that are building next generation everyday financial services on Stellar.

We are grateful for everyone who 1has been a part of this journey. From SDF team members to our supportive community of builders, this was only possible with a lot of keystrokes, support, and belief in the vision for secure, scalable, and easy-to-build smart contracts on Stellar.

THE PHASED ROLLOUT

But this ride is not over. Today's vote marks the beginning of a phased rollout where validators, who vote to configure network settings, will increase capacity for smart contract transactions in a series of methodical steps. The phased approach will give those validators, as well as other network participants, time to monitor smart contract functionality's impact on the network and ensure performance, security, and stability at every step.

Gradually, validators plan to increase limits for Soroban transactions, building up to full capacity. As the increases happen and we enter phase 1, theĀ 160+ buildersĀ and projects already building on Testnet will begin to deploy on Mainnet. Later, once projects are deployed, the network has been stress-tested, and the ecosystem is satisfied, dapps will launch for all to use. SDF will communicate throughout the process, but the initial details on the rollout can be foundĀ hereĀ or in the video below for those interested.

LOW-COST, SECURE AND SCALABLE

Stellar is a network that is low cost, fast, and built to scale, with a global reach to a growing share of the world's underserved population. Now with smart contracts on Stellar a whole new world is opening up for builders, where security, affordability, and scalability aren'tĀ onĀ the roadmap but built into the code, with resources and tools for the masses, and access to an ecosystem that is already delivering real-world utility.

SECURE & EASY TO BUILD

It's no secret that smart contracts are not easy to write.

The blockchain industry has opted to spin up its own way of doing things instead of leaning on tried and true tools. It requires developers to spend energy, time, and mindshare learning new platforms and bespoke languages to tinker and build. There are bugs and vulnerabilities codified into other chains. Taken together this can make any developer want to stop before they get started. For Soroban, security and ease of building were priority #1. In collaboration and consultation with the ecosystem, intentional design decisions were made so builders wouldn't need to start from scratch or choose performance over security. Together, a decision was made to use Rust and WASM – tested and well-known tools – for Soroban's tech stack to build an experience prioritizing safety, speed, and familiarity. We set out to build something anyone could build on, making the hurdle from idea to deployment shorter and more manageable so builders can create faster.

SCALABLE AND EFFICIENT

Scalability and efficiency are the bread and butter of any platform worth its salt. You shouldn't have to compromise when building a platform meant to revolutionize the world's financial systems. Transaction costs need to be low, fees must be predictable, and the platform needs to be able to handle growth. This is where smart contracts on Stellar shine. Soroban engineers have conducted research that influenced the design of specific features that support network scalability and sustainability. For example, Soroban employs aĀ fees and metering structureĀ that allows individual resource consumption (such as ledger entry reads and writes, CPU instructions, and RAM) to be priced independently, and it offers a state-of-the-artĀ method for archiving stateĀ that solves the age-old blockchain problem of state bloat. No retroactive fixes or massive upgrades are needed to solve problems that can be solved from the beginning.

GROUNDED IN THE REAL WORLD FOR REAL PEOPLE

And let's not forget the reason we're all here – to offer people tools that make their lives easier and better. Blockchain can grant access to a whole world of financial opportunity, but until now, many people have been stuck on the sidelines, watching from afar. Simply put, transaction costs on certain chains are a barrier to entry, and the lack of on and off-ramp infrastructure keeps users without the ability to get in and out of the digital economy. No bank account? No problem. For the last ten years, the Stellar ecosystem has amassed the necessary building blocks for this moment, growing the number ofĀ asset issuers,Ā on and off-ramps, andĀ walletsĀ on the network. Now, with smart contracts, dapps can participate in a new era of inclusivity, opening the door for builders to reach untapped markets around the globe and giving users access to financial services and applications like never before—pioneering finance for every pocket.

RELIABLE AND PROVEN

With a decade of experience, the Stellar ecosystem is a well-oiled machine. The worries of building on an unproven platform don't apply here. Whether you're a developer, entrepreneur, or someone with a killer idea, Stellar has everything you need to hit the ground running. With Stellar, you're starting on solid ground with a network ofĀ top-tier exchanges,Ā on and off-ramps, custody providers, wallets, and a whole host of other resources on a proven, reliable network ready to power your project on day 1.
Ā 
Today marks a beginning not an end, so stay connected, get ready to deploy and be part of the growing community shaping the future of decentralized finance.

The Great Onboarding: US Government Anchors Global Economy into Web3 via Pyth Network

For years, the crypto world speculated that the next major cycle would be driven by institutional adoption, with Wall Street finally legitimizing Bitcoin through vehicles like ETFs. While that prediction has indeed materialized, a recent development signifies a far more profound integration of Web3 into the global economic fabric, moving beyond mere financial products to the very infrastructure of data itself. The U.S. government has taken a monumental step, cementing Web3's role as a foundational layer for modern data distribution. This door, once opened, is poised to remain so indefinitely.

The U.S. Department of Commerce has officially partnered with leading blockchain oracle providers, Pyth Network and Chainlink, to distribute critical official economic data directly on-chain. This initiative marks a historic shift, bringing immutable, transparent, and auditable data from the federal government itself onto decentralized networks. This is not just a technological upgrade; it's a strategic move to enhance data accuracy, transparency, and accessibility for a global audience.

Specifically, Pyth Network has been selected to publish Gross Domestic Product (GDP) data, starting with quarterly releases going back five years, with plans to expand to a broader range of economic datasets. Chainlink, the other key partner, will provide data feeds from the Bureau of Economic Analysis (BEA), including Real Gross Domestic Product (GDP) and the Personal Consumption Expenditures (PCE) Price Index. This crucial economic information will be made available across a multitude of blockchain networks, including major ecosystems like Ethereum, Avalanche, Base, Bitcoin, Solana, Tron, Stellar, Arbitrum One, Polygon PoS, and Optimism.

This development is closer to science fiction than traditional finance. The same oracle network, Pyth, that secures data for over 350 decentralized applications (dApps) across more than 50 blockchains, processing over $2.5 trillion in total trading volume through its oracles, is now the system of record for the United States' core economic indicators. Pyth's extensive infrastructure, spanning over 107 blockchains and supporting more than 600 applications, positions it as a trusted source for on-chain data. This is not about speculative assets; it's about leveraging proven, robust technology for critical public services.

The significance of this collaboration cannot be overstated. By bringing official statistics on-chain, the U.S. government is embracing cryptographic verifiability and immutable publication, setting a new precedent for how governments interact with decentralized technology. This initiative aligns with broader transparency goals and is supported by Secretary of Commerce Howard Lutnick, positioning the U.S. as a world leader in finance and blockchain innovation. The decision by a federal entity to trust decentralized oracles with sensitive economic data underscores the growing institutional confidence in these networks.

This is the cycle of the great onboarding. The distinction between "Web2" and "Web3" is rapidly becoming obsolete. When government data, institutional flows, and grassroots builders all operate on the same decentralized rails, we are simply talking about the internet—a new iteration, yes, but the internet nonetheless: an immutable internet where data is not only published but also verified and distributed in real-time.

Pyth Network stands as tangible proof that this technology serves a vital purpose. It demonstrates that the industry has moved beyond abstract "crypto tech" to offering solutions that address real-world needs and are now actively sought after and understood by traditional entities. Most importantly, it proves that Web3 is no longer seeking permission; it has received the highest validation a system can receive—the trust of governments and markets alike.

This is not merely a fleeting trend; it's a crowning moment in global adoption. The U.S. government has just validated what many in the Web3 space have been building towards for years: that Web3 is not a sideshow, but a foundational layer for the future. The current cycle will be remembered as the moment the world definitively crossed this threshold, marking the last great opportunity to truly say, "we were early."

US Dept of Commerce to publish GDP data on blockchain

On Tuesday during a televised White House cabinet meeting, Commerce Secretary Howard Lutnick announced the intention to publish GDP statistics on blockchains. Today Chainlink and Pyth said they were selected as the decentralized oracles to distribute the data.

Lutnick said, ā€œThe Department of Commerce is going to start issuing its statistics on the blockchain because you are the crypto President. And we are going to put out GDP on the blockchain, so people can use the blockchain for data distribution. And then we’re going to make that available to the entire government. So, all of you can do it. We’re just ironing out all the details.ā€

The data includes Real GDP and the PCE Price Index,Ā which reflects changes in the prices of domestic consumer goods and services. The statistics are released monthly and quarterly. The biggest initial use will likely be by on-chain prediction markets. But as more data comes online, such as broader inflation data or interest rates from the Federal Reserve, it could be used to automate various financial instruments. Apart from using the data in smart contracts, sources of tamperproof data šŸ‘‰will become increasingly important for generative AI.

While it would be possible to procure the data from third parties, it is always ideal to get it from the source to ensure its accuracy. Getting data directly from government sources makes it tamperproof, provided the original data feed has not been manipulated before it reaches the oracle.

List Of Cardano Wallets

Well-known and actively maintained wallets supporting the Cardano Blockchain areĀ Eternl,Ā Typhon,Ā Vespr,Ā Yoroi,Ā Lace,Ā ADAlite,Ā NuFi,Ā Daedalus,Ā Gero,Ā LodeWallet,Ā Coin Wallet,Ā ADAWallet,Ā Atomic,Ā Gem Wallet,Ā TrustĀ andĀ Exodus.

Note that in case of issues, usually only queries relating to official wallets can be answered in Cardano groups across telegram/forum. You may need to consult with specific wallet support teams for third party wallets.

Tips

  • Its is important to ensure that you're in sole control of your wallet keys, and that the keys used can be restored via alternate wallet providers if a particular one is non-functional. Hence, put extra attention toĀ Non-CustodialĀ andĀ CompatibilityĀ fields.
  • The score column below is strictly a count of checks against each feature listed, the impact of specific feature (and thus, score) is up to reader's descretion.
  • The table represents current state on mainnet network, any future roadmap activities are out-of-scope.
  • Info on individual fields can be found towards the end of the page.
  • Any field that shows partial support (eg: open-source field) does not score the point for that field.

Brief info on fields above

  • Non-Custodial: are wallets where payment as well as stake keys are not shared/reused by wallet provider, and funds can be transparently verified on explorer
  • Compatibility: If the wallet mnemonics/keys can easily (for non-technical user) be used outside of specific wallet provider in major other wallets
  • Stake Control: Freedom to elect stake pool for user to delegate to (in user-friendly way)
  • Transparent Support: Easy approachability of a public interactive - eg: discord/telegram - group (with non-anonymous users) who can help out with support. Twitter/Email supports do not count for a check
  • Voting: Ability to participate in Catalyst voting process
  • Hardware Wallet: Integration with atleast Ledger Nano device
  • Native Assets: Ability to view native assets that belong to wallet
  • dApp Integration: Ability to interact with dApps
  • Stability: represents whether there have been large number of users reporting missing tokens/balance due to wallet backend being out of sync
  • Testnets Support: Ability to easily (for end-user) open wallets in atleast one of the cardano testnet networks
  • Custom Backend Support: Ability to elect a custom backend URL for selecting alternate way to submit transactions transactions created on client machines
  • Single/Multi Address Mode: Ability to use/import Single as well as Multiple Address modes for a wallet
  • Mobile App: Availability on atleast one of the popular mobile platforms
  • Desktop (app,extension,web): Ways to open wallet app on desktop PCs
  • Open Source: Whether the complete wallet (all components) are open source and can be run independently.
