DeFi, payments, tokenization, Soroban, governance, and project launches — curated daily from publications, project blogs, and community channels across the Stellar blockchain ecosystem.
Protocol 25 and 26 introduced zero-knowledge primitives (BN254, Poseidon) that make private payment systems practical on Stellar. Arcane is building production infrastructure for compliance-ready privacy, enabling builders to protect sensitive financial flows on public rails while maintaining clear disclosure and reporting paths.
Founder Josh built Peridot after realizing DeFi's core problem: fragmented liquidity and painful capital movement across chains. The bootstrapped team has shipped a Hub & Spoke cross-chain lending protocol live on Stellar and other networks with competitive yields. Next: margin trading, dual investment products, and an AI agent for portfolio guidance.
The Stellar Development Foundation announced a three-stage roadmap to migrate the network to post-quantum cryptography by 2027+. Quantum computers will eventually break the elliptic curve cryptography securing blockchains. Stellar's separation of account identity from signing keys avoids disruptive address migration unlike Bitcoin and Ethereum.
Stellar Philippines and Rise In concluded 'Build the Future of Finance' hackathon on May 23 with 165 registrations and 28 mainnet deployments in Manila. Five winners addressed financial infrastructure gaps: AbotPera (zero-connectivity rural payments), PinkRaft (Soroban developer tools), Axial (MSME liquidity), Sobre (overseas worker remittances), and TyFi (agricultural worker credit).
Homomorphic encryption enables computations on encrypted data without decryption—the results match plaintext outcomes. For enterprise and tokenized real-world assets, this unlocks confidential balances, compliance checks, and transaction logic that stays hidden from counterparties while the network coordinates outcomes.
Nectar Network announced a $75K Build award from SCF #42 for its liquidation protocol on Soroban. The keeper network replaces single-operator liquidation bots with pooled capital and competing staked operators, removing a systemic risk point in lending markets. Live on testnet.
Inferara completes its third Stellar Community Fund milestone, delivering the Inference formal verification language for Soroban. The toolchain enables developers to mathematically prove smart contract correctness using familiar imperative syntax, addressing security gaps in institutional-scale DeFi.
Offer-Hub launches a marketplace orchestration platform that enables founders to build scalable marketplaces without rebuilding payments, escrow, and settlement infrastructure. A production freelance marketplace demo processed 82 user registrations, created 11 escrows, and executed 4 settlement transactions on Stellar, demonstrating that users can benefit from blockchain infrastructure without directly managing wallets or seed phrases.
EduNode explains zero-knowledge proofs on Stellar: cryptographic foundations, the three pillars of ZK, and five real-world use cases from private transactions to off-chain computation. Privacy Pools on Soroban are under development.
The Boundless × Trustless Work Hackathon wrapped with 31 projects from 114 Nigerian builders. Projects showcased eight escrow use case themes: work and freelancing, AI agent task payments, grant funding and bounties, deposits and physical trust, community finance and savings traditions, P2P trade and OTC settlement, escrow tooling and no-code builders, and parametric insurance-style logic. Conductor won the grand prize.
Trustless Work V2 replaces a rigid escrow workflow with flexible primitives. Multi-address roles, quorum-based approvals, batch operations, and dedicated admin/observer roles let platforms design custom escrow flows for marketplaces, grants, DAOs, and payments.
CertiK explores two critical vulnerabilities in Soroban contract state storage: storing long-term data in Temporary storage risks irreversible loss when entries expire; relying on TTL expiry alone for nonce validation enables signature replay attacks. The article walks through vulnerable code patterns and secure alternatives using Persistent and Instance storage.
The CLARITY Act moving toward passage (now at 75% probability) would establish federal licensing for payment stablecoins, unlocking autonomous agents transacting at machine speed. Three competing architectures - x402 on Base, Soroban on Stellar, and Solana platforms - are racing to capture trillions of micro-transactions between machines.
Stellar's Soroban smart contract runtime features a composable authorization model that decouples authorization from fee payment, enabling sponsored transactions, multi-party swaps, and programmable accounts through detachable auth entries and flexible verification logic.
Certora outlines a practical threat modeling approach for Soroban smart contracts using the 4 A's framework (Assets, Actors, Assumptions, Attack Vectors) and …
Stellar Protocol 26, called Yardstick, went live on mainnet May 6, 2026. The upgrade introduces Quorum Freeze for governed incident response, checked arithmet…
Certora released updates to its Prover tools across multiple blockchains: EVM now displays storage paths for unresolved calls, Solana Prover added rule splitt…
Trustless Work is an Escrow-as-a-Service platform for stablecoins that lets developers integrate secure, non-custodial, milestone-based escrow payments without building smart contracts from scratch. The guide covers product fundamentals, use cases, developer tools, and a recommended builder journey.
OctoLend introduces collateral vaults as a bridge enabling RWAs to work with DeFi lending protocols. By delegating liquid XLM collateral, institutional borrowers can access RWA-backed leverage while maintaining compliance with redemption windows and KYC requirements.
Kuyfi, a black-box security scanner for Soroban smart contracts, launches its first phase. It analyzes contract bytecode without requiring source code, addressing a critical gap in DeFi security for protocols like Soroswap and Blend.
Tellus Cooperative hosted Stellar Academy in Temuco, Chile, bringing 50+ participants together for hands-on smart contract training. The event centered on Stellar Passport, a Web3 identity tool that participants configured in real-time, demonstrating accessible onboarding for the Stellar ecosystem.
Certora and the Stellar Development Foundation published a comprehensive guide for preparing Soroban smart contracts for security audits through the Audit Bank program, covering threat modeling, code quality, testing, and security tooling.
Bastian built Calypso, an AI-powered autonomous agent system that spawns trading bot swarms across Stellar DEXes using x402 micropayments. The hackathon project serves as the technical foundation for Hoops Finance's next phase, enabling realistic testnet market conditions and agent-native DeFi strategy execution.
Splyce closes a strategic round backed by Sui, Stellar, and Solana foundations plus institutional allocators Lucid, Sarson, and Kin Capital. The company launches Single Asset Vaults, fixed-rate lending markets with zero oracles, plus splyceUSDC, a 7-8% yield token. The thesis: $300B+ tokenized RWAs need credit infrastructure, not DEX liquidity, to become productive capital.
