Solana Tech Pulse 🔧 @JPoolSolana launched a dedicated Discord hub for validators. A space for validators to connect, share insights, and stay updated on JPool programs and network tools. Validators can now verify and claim their roles via the ticket system to access exclusive channels and announcements. 🔧 @Solana joined the Cross‑Chain Payment Alliance alongside @FireblocksHQ, @monad, @ton_blockchain, @0xPolygon, @StellarOrg and @Mysten_Labs to standardize cross‑chain stablecoin payments. The initiative aims to enable fast, low‑cost, compliant on‑chain settlement for a unified global payments network targeting $10T+ in volume. 🔧 @harmonic_gg — a new block-building system for @solana — launched to enable novel market structures and on-chain perps venues. Designed to improve competitive parity with centralized exchanges by keeping block construction open, fast, and fair. 🔧 @JupiterExchange launches Limit Order v2 on Solana: set $USD price or market‑cap targets without pool math; bundle multiple orders with one‑cancels‑other (OCO); Buy Above and Sell Below execute at the limit price (not market) for greater control; edit live orders on the go; orders remain private until trigger to reduce front‑running. Powered by Jupiter. 🔧 @stakefy's x402 SDK is now one of the most used payment facilitators on Solana, ranking just behind @coinbase in adoption. x402 SDK adds session budgets, pay-by-username, and ZK-proof receipts to enable verifiable, programmable payments. 🔧 Full-node count: @solana mainnet is at nearly 6,000 full nodes. SFDP change: The SFDP was scaled back because heavy demand for Solana state led operators to replicate state without economic incentives to serve applications. Network comparison: ~6k full nodes on Solana vs ~8k on @ethereum (per source). The week begins — Solana’s gears are already turning! 🔧
