A technical guide comparing data types between Solidity (EVM) and Rust (Soroban), part 2 of a migration series. The article covers primitive and composite types, key differences like String vs. Symbol, and provides code examples for both languages.

Stellar's Soroban smart contracts platform went live on mainnet after two years of testing, enabling developers to build decentralized applications. The SDF allocated $100 million to a Soroban adoption fund that has already supported over 160 projects.

The Stellar Development Foundation submitted a response to the U.S. Treasury's Request for Information on Financial Inclusion, advocating for open-source blockchain technology and transparent systems to advance financial access. SDF emphasized the importance of free or low-cost digital financial services, smart contracts, and open data initiatives in creating inclusive financial systems.

Soroban has reached phase 1 on mainnet, enabling the deployment of a registry contract for Soroban Domains. The team has updated the code to support subdomain registration and invalidation, with plans for domain transfer and liquidation features. They are also integrating support into xBull Wallet and excited for Stellar ecosystem developments.

A roundup of global crypto regulations, adoption trends, and developments, including UK stablecoin laws, Hong Kong licensing, and South Africa's embrace of stablecoins. Highlights mainstream adoption like Swiss Postfinance's crypto services and Web3 hurdles. Notably features the launch of smart contracts on the Stellar network, marking a new era for the blockchain.

Stellar launched smart contracts on Mainnet on Feb. 20 with a phased rollout prioritizing network stability. Over 160 projects on Testnet will gradually deploy as transaction limits increase, enabling low-cost DeFi applications built on Rust and WASM.

Stellar mainnet upgraded to Protocol 20, introducing Soroban smart contract platform built on WebAssembly and Rust. The upgrade enables custom code execution while preserving Stellar's payments infrastructure and institutional compliance focus.

Dropzey is an innovative platform revolutionizing airdrops by simplifying creation and participation processes. It addresses inefficiencies through user-friendly tools, verification mechanisms, and transparency features. By integrating with Stellar and Soroban Smart Contracts, it enables automated and instant token distribution.

This article provides a comprehensive overview of Decentralized Finance (DeFi) and its implementation on the Stellar blockchain. It explains DeFi's core components—including blockchain, smart contracts, DEXs, and liquidity pools—and highlights how Soroban, Stellar's native smart contracts platform, enables developers to build DeFi applications with access to real-world financial rails.

A comprehensive tutorial on migrating smart contracts from Ethereum's Solidity to Soroban's Rust SDK, comparing the two languages and providing step-by-step examples of building a 'Hello World' contract in both environments.

The Stellar Development Foundation released its Q4 2023 quarterly report highlighting major ecosystem achievements including Protocol 20 support, Soroban mainnet rollout, $4M in SCF funding to 88 projects, and over $2M in humanitarian aid disbursed via the Stellar Disbursement Platform.

Stellar network validators postponed the Protocol 20 upgrade vote due to a bug discovered in Stellar Core v20.1.0. The SDF has outlined a new timeline with a bug fix release on February 2, testnet reset on February 6, and a target Protocol 20 upgrade vote on February 20.

Stellar Development Foundation delayed its Protocol 20 upgrade beyond Jan. 30 after discovering a bug in Soroban smart contracts software. Six of seven tier-1 validators signaled support for postponement, likely preventing the upgrade from reaching quorum.

The Stellar Development Foundation has decided to disarm its validators and postpone the Protocol 20 upgrade scheduled for January 30, 2024, following ecosystem concerns about a discovered bug in Stellar Core v20.1.0 affecting fee bumps for Soroban transactions.

The Stellar Development Foundation disclosed a bug in Stellar Core v20.1.0 affecting fee-bumped Soroban transactions, where refunds are incorrectly sent to the sponsored account instead of the sponsor. SDF decided to proceed with the Protocol 20 upgrade vote on January 30 as planned, citing low risk during early Soroban phases and the availability of mitigation best practices.

This tutorial provides a step-by-step guide to deploying a Soroban RPC server on DigitalOcean Kubernetes using Stellar Development Foundation Helm charts. It covers cluster creation, Helm repository setup, configuration for testnet, Nginx Ingress installation, DNS setup, and verification. Benefits include improved reliability, control, and performance for Stellar smart contract interactions.

Blend, a permissionless on-chain lending protocol, has launched on Stellar Testnet. Users can now test lending, borrowing, and backstopping features using browser wallets like Freighter. The protocol offers high capital efficiency, flexible pools, and risk mitigations for the Stellar DeFi ecosystem.

Nebula, a Soroban contract library built by Eiger, aims to simplify smart contract development on Stellar by providing security-audited components, templates, and a user-friendly contract wizard to accelerate dapp deployment and lower barriers to entry for developers.

Aquarius announces updates and 2024 plans for building AMMs on Stellar using Soroban smart contracts. They've developed CPMM and StableSwap models inspired by Uniswap and Curve, with AQUA rewards for liquidity providers. A new UI and integrations are planned post-Soroban mainnet launch on January 30, 2024.

Stellar Development Foundation announced Protocol 20 upgrade with Soroban smart contracts, scheduled for January 30 validator vote on Mainnet. The network will roll out smart contract functionality in three phased stages to ensure stability and performance.
