DeFi, payments, tokenization, Soroban, governance, and project launches — curated daily from publications, project blogs, and community channels across the Stellar blockchain ecosystem.
Soroban's fee structure uses granular resource metering to price compute, memory, and storage independently, enabling more efficient block utilization and lower validator costs than traditional gas-based systems like Ethereum's.
Stellar Development Foundation proposes limiting transaction submission to one per source account per ledger to improve network scalability and safety ahead of Soroban support in Protocol 20. Channel accounts remain the recommended solution for high-throughput applications.
Stellar Core v18.2.0 introduces a traffic-shaping feature to mitigate failed arbitrage bot transactions that have been bloating the ledger and increasing network fees. The feature allows validators to filter circular path payment transactions destined to fail while preserving healthy arbitrage activity.
A comprehensive FAQ addressing common transaction submission errors on Stellar, particularly 504 timeout errors. The article explains how dynamic fees work, surge pricing mechanics, ledger limits, and provides practical guidance for developers to optimize transaction submission and avoid timeouts.
The Stellar Development Foundation proposes raising the network's minimum transaction fee from 100 stroops to 10,000 stroops per operation to combat failed arbitrage bot transactions that clog the ledger and cause unpredictable surge pricing.
The Stellar public network successfully upgraded to Protocol 13, introducing new features like fee-bump transactions and fine-grained asset authorization. Developers must update their software to avoid compatibility errors.
Protocol 13 introduces fee-bump transactions to the Stellar network, allowing users to increase transaction fees without requiring new signatures from all parties. This solves the problem of pre-signed transactions becoming unexecutable when network fees rise unexpectedly.
Stellar Core Protocol 13 introduces three major features: fee bumps for flexible transaction fee management, fine-grained asset authorization for regulated assets, and multiplexed accounts with built-in memos for custodial services. The public network will vote to upgrade on June 18, requiring all ecosystem participants to update their software.
Stellar Protocol 11 upgrade introduces three major improvements: better transaction pricing using VCG auctions, increased network capacity through operations-per-ledger limits, and new buy offer operations for clearer market ordering.
A 2019 blog post explaining Stellar's Surge Pricing mechanism during a period of high network congestion. The post clarifies that the network is functioning as designed, describes how fees work during peak activity, and outlines SDF's scaling efforts.
