News, tools, and resources for developers building the next generation of Web3 apps.https://stacksmith.xyzhttps://stacksmith.xyz/articles/solana-sbpfv3-migrationhttps://stacksmith.xyz/articles/solana-sbpfv3-migrationAnza has published a migration guide for SBPFv3, the bytecode format that becomes the only deployable one on Solana once SIMD-0500 activates in Agave v4.4. Deployed programs keep running, but 17,332 upgradeable programs still on old bytecode will need a rebuild before they can ship another upgrade.Wed, 16 Sep 2026 20:00:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-x402-four-pillars-reporthttps://stacksmith.xyz/articles/solana-x402-four-pillars-reportFour Pillars' 131-page x402 report models annual agent payment volume reaching as high as $1.9T by 2028, with roughly 96% of it landing in purchases an agent makes without a human approving anything. Solana already handles about 70% of x402 protocol volume, so the report's headline scenario is running today on rails that shipped this year, from Pay.sh to Ramp's 70,000 business wallets.Tue, 15 Sep 2026 16:02:00 GMTMike Halehttps://stacksmith.xyz/articles/dev3pack-hackathonhttps://stacksmith.xyz/articles/dev3pack-hackathonDev3pack is running its global hackathon October 30 to November 1, 2026, a three-day hybrid event with more than 40 in-person build stations across four continents. The three days sit in the middle of a longer program that opens with a free Solana Rust bootcamp on October 6 and ends with three months in the Bridge Accelerator for the teams that place.Mon, 14 Sep 2026 19:16:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-accelerate-chinahttps://stacksmith.xyz/articles/solana-accelerate-chinaSolana Accelerate China is back for a second year, running October 16 to 22 with single-day stops in Shanghai, Hangzhou, Shenzhen, and Beijing. Each city has its own Luma page and a single General Admission ticket, with the Solana Foundation hosting all four and internet capital markets as the stated theme.Sun, 13 Sep 2026 21:01:00 GMTMike Halehttps://stacksmith.xyz/articles/stocklana-hackathonhttps://stacksmith.xyz/articles/stocklana-hackathonThe Solana Foundation opened STOCKLANA, a one-week hackathon with $100,000 in prizes for apps built around stocks on Solana, with submissions closing Friday, September 18 at 4:00 pm ET. It is also the launch event for hackathons.solana.com, a self-serve platform where the community proposes hackathon themes, votes on them, and funds bounty tracks with USDC held in onchain escrow.Fri, 11 Sep 2026 19:11:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-foundation-rust-foundation-platinumhttps://stacksmith.xyz/articles/solana-foundation-rust-foundation-platinumThe Solana Foundation is now a Platinum member of the Rust Foundation, the top tier, which comes with a seat on the board that decides how the Rust Foundation spends its money. It joined at RustConf 2026 in Montreal alongside NVIDIA and is the only blockchain organization among nine Platinum members that include AWS, Google, Microsoft, and OpenAI.Thu, 10 Sep 2026 20:07:35 GMTMike Halehttps://stacksmith.xyz/articles/clock-in-solana-mobile-hackathonhttps://stacksmith.xyz/articles/clock-in-solana-mobile-hackathonSolana Mobile and RadiantsDAO have opened Clock In, a four-week hackathon putting $135,000 behind mobile-first Solana apps, with submissions closing October 9, 2026. Ten teams get paid, the deliverable is a working Android APK rather than a pitch, and winners have 30 days to ship to the Solana dApp Store.Wed, 09 Sep 2026 14:11:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-tokenized-assets-settlementhttps://stacksmith.xyz/articles/solana-tokenized-assets-settlementSolana Foundation president Lily Liu argues that tokenization is a decades-long “token supercycle,” and a new Allium report backs a good part of that up. Solana executes about a third of all onchain RWA trading, but it holds just 12% of the market cap, and $1.7 billion of institutional balances sitting on it never trade at all.Tue, 08 Sep 2026 15:51:00 GMTMike Halehttps://stacksmith.xyz/articles/simd-0437-rent-reduction-mainnethttps://stacksmith.xyz/articles/simd-0437-rent-reduction-mainnetThe first step of SIMD-0437 activated at mainnet epoch 1028, dropping lamports_per_byte from 6,960 to 6,333. Four more feature gates follow, each one waiting on state growth data, until Solana's storage cost lands 90% below where it started.Mon, 07 Sep 2026 22:17:00 GMTMike Halehttps://stacksmith.xyz/articles/google-solana-ai-agentic-hackathon-demo-dayhttps://stacksmith.xyz/articles/google-solana-ai-agentic-hackathon-demo-daySuperteam Korea has published the recap of the Google Cloud and Solana AI Agentic Hackathon Demo Day, where 10 finalist teams out of 160 builders competed for a $5,000 Solana Foundation grant pool. The more useful result is that all ten converged on the same architecture, splitting AI judgment from code-enforced spending limits.Sat, 05 Sep 2026 18:47:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-payment-channelshttps://stacksmith.xyz/articles/solana-payment-channelsThe Solana Foundation shipped payment channels, a primitive that lets an AI agent authorize a spending cap once and settle the real amount in a single onchain transaction. In testing, 100,000 wallets pushed more than 1 million payments per second through a payment channel proxy at an estimated $0.000000000776 per payment, and Alibaba Cloud is live with it at launch.Fri, 04 Sep 2026 15:50:00 GMTMike Halehttps://stacksmith.xyz/articles/crypto-worlds-fair-hackathonhttps://stacksmith.xyz/articles/crypto-worlds-fair-hackathonColosseum has opened registration for the Crypto World's Fair, an online hackathon running September 14 to October 12, 2026 that is open to builders on every blockchain rather than Solana alone. Every submission is eligible for prizes regardless of chain, though the $250,000 pre-seed check and the accelerator seat behind it still go only to Solana teams.Thu, 03 Sep 2026 17:50:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-incubator-cohort-5https://stacksmith.xyz/articles/solana-incubator-cohort-5Solana Labs named six teams to Cohort 5 of the Solana Incubator, a three-month program that puts founders in New York City building alongside the Solana Labs team. The group runs from robot fleets and agentic finance to opinion markets and verifiable trade settlement, and applications for the next cohort open in October.Wed, 02 Sep 2026 15:47:00 GMTMike Halehttps://stacksmith.xyz/articles/opensea-solana-nftshttps://stacksmith.xyz/articles/opensea-solana-nftsOpenSea has relaunched Solana NFT trading on its OS2 marketplace, four years after its original 2022 beta stalled out with only 165 collections. The comeback opens with five collections, including Claynosaurz and Mad Lads, and follows Rarible's own Solana NFT relaunch three weeks earlier.Tue, 01 Sep 2026 15:50:31 GMTMike Halehttps://stacksmith.xyz/articles/solana-university-ambassador-programhttps://stacksmith.xyz/articles/solana-university-ambassador-programSolana has opened the Solana University Ambassador Support Program, a paid, one-semester role for two student ambassadors per participating university who run Workshops, Build Nights, and Demo Days from September through December. Ambassadors get a USDC stipend, event funding, full RPC/AI/data toolkit access, and a shot at Breakpoint or Accelerate for top performers, with applications closing September 1, 2026.Sat, 29 Aug 2026 20:04:00 GMTMike Halehttps://stacksmith.xyz/articles/sns-domain-upgradehttps://stacksmith.xyz/articles/sns-domain-upgradeSolana Name Service is migrating every existing .sol domain to .sns, and holders caught in the August 17 snapshot get a matching new .sol domain for free on the Solana Record Service. The upgrade is automatic with no claim step, but .sol resolution pauses at slot 452,825,395 in mid to late October, so .sns becomes the name to use for payments.Fri, 28 Aug 2026 15:30:00 GMTMike Halehttps://stacksmith.xyz/articles/kamino-fixed-rateshttps://stacksmith.xyz/articles/kamino-fixed-ratesKamino has launched Fixed Rates, a fixed-rate, fixed-term credit market built directly into Kamino Lend, with the first loans already originated in private beta. Borrowers set a rate ceiling and a term through Borrow Intents, while lenders quote terms through Conditional Liquidity without pulling capital out of the variable-rate reserves where it is already earning.Thu, 27 Aug 2026 14:55:00 GMTMike Halehttps://stacksmith.xyz/articles/state-of-solana-dashboard-defi-development-corphttps://stacksmith.xyz/articles/state-of-solana-dashboard-defi-development-corpDeFi Development Corp launched State of Solana, a free public dashboard pulling SOL price and returns, live network throughput, staking yields, validator concentration, and cross-chain comparisons into a single page. It also tracks Solana's scheduled protocol upgrades, which most crypto dashboards leave out entirely.Wed, 26 Aug 2026 20:00:00 GMTMike Halehttps://stacksmith.xyz/articles/velocity-dex-private-betahttps://stacksmith.xyz/articles/velocity-dex-private-betaVelocity, the Solana perps exchange formerly known as Drift, opened a private beta with a 0.02% fee tier applied from a trader's first trade. The rebuild follows Drift's $285 million hack in April 2026, and traders can now earn yield on the same SOL or USDT balance that backs their positions.Tue, 25 Aug 2026 21:41:59 GMTMike Halehttps://stacksmith.xyz/articles/bench-hiring-markets-arcium-solanahttps://stacksmith.xyz/articles/bench-hiring-markets-arcium-solanaBench, built by the encrypted computation network Arcium, turns job hiring into a confidential prediction market on Solana, letting vouchers stake capital on candidates without competitors or the hiring company seeing where the money is going until the role is filled. Its devnet alpha drew 900 participants across 12 markets and $7.67 million in combined stake volume before the August 24, 2026 mainnet launch.Mon, 24 Aug 2026 22:08:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-id-shutting-downhttps://stacksmith.xyz/articles/solana-id-shutting-downSolana ID is shutting down, with the Hub, API, and Display Network going offline September 30, 2026 and user data deleted by year-end. The team burned 73.78% of the total SOLID supply from its own treasury and already returned all 13.8 million staked SOLID across 1,239 wallets with zero failures.Sat, 22 Aug 2026 18:17:00 GMTMike Halehttps://stacksmith.xyz/articles/seeker-usdc-earn-vault-kaminohttps://stacksmith.xyz/articles/seeker-usdc-earn-vault-kaminoSolana Mobile has launched the USDC Earn Vault in Seed Vault Wallet, giving Seeker owners a one-tap way to earn variable yield on USDC through Kamino's SOL/BTC lending market. It routes 95% of deposits into the lending pool and keeps 5% in reserve, with no lockup, no minimum deposit, and a flat 0.25% annual fee already netted out of the APY on your home tab.Fri, 21 Aug 2026 14:37:00 GMTMike Halehttps://stacksmith.xyz/articles/anchor-v2-release-candidatehttps://stacksmith.xyz/articles/anchor-v2-release-candidateAnchor v2.0.0-rc.1 is a complete rewrite of Solana's most widely used program framework, rebuilt on Pinocchio with binaries over 90% smaller and compute costs three to six times lower than v1. The release candidate ships coverage-guided fuzzing through Crucible, plus a profiler, a step debugger, and LCOV coverage as first-class CLI subcommands.Thu, 20 Aug 2026 17:03:00 GMTMike Halehttps://stacksmith.xyz/articles/rain-agentic-payments-alliancehttps://stacksmith.xyz/articles/rain-agentic-payments-allianceRain has launched the Agentic Payments Alliance, a coalition of more than two dozen founding members including Visa, Mastercard, Solana, Circle, and Fiserv, to set shared standards for how AI agents make payments on a user's behalf. The group operates as a collective working group rather than a Rain-owned project, with early work covering agent identity, authorization, fraud detection, and regulatory advocacy ahead of a market McKinsey projects at $3 trillion to $5 trillion by 2030.Wed, 19 Aug 2026 14:24:38 GMTMike Halehttps://stacksmith.xyz/articles/solana-mobile-bug-bounty-programhttps://stacksmith.xyz/articles/solana-mobile-bug-bounty-programSolana Mobile has launched a Vulnerability Disclosure Policy and Bug Bounty Program that pays researchers up to $75,000 in SKR for critical vulnerabilities in Seed Vault, SKR's onchain programs, and Seeker Genesis Token infrastructure. Rewards are paid under a signed Award Agreement across four severity tiers, and a separate Security Grants program launched alongside it.Tue, 18 Aug 2026 14:32:27 GMTMike Halehttps://stacksmith.xyz/articles/solana-school-fall-classhttps://stacksmith.xyz/articles/solana-school-fall-classSolana Foundation is running Solana School's Fall Class from August 31 through October 16, a free, seven-week, cohort-based program that ships working code every session, three times a week. Unlike the summer cohort, which required a college email, the Fall Class is open to any developer who applies, ending in a Demo Day pitched as practice for Colosseum.Mon, 17 Aug 2026 18:11:10 GMTMike Halehttps://stacksmith.xyz/articles/nexus-mutual-solana-coverhttps://stacksmith.xyz/articles/nexus-mutual-solana-coverNexus Mutual has extended DeFi coverage to Solana for the first time, with live listings for Kamino, Raydium, Orca, and Jupiter spanning roughly 90% of Solana lending deposits. The mutual has paid 100% of valid claims across more than $7 billion in cover written over seven years, all of it previously confined to Ethereum and other EVM chains.Sat, 15 Aug 2026 13:00:00 GMTMike Halehttps://stacksmith.xyz/articles/cdp-sql-api-solanahttps://stacksmith.xyz/articles/cdp-sql-api-solanaCoinbase Developer Platform has brought its SQL API to Solana in beta, letting developers query SPL Token and Token-2022 activity with plain SQL instead of running an indexer. Two datasets ship at launch, with 500ms freshness to the tip of the chain and 1,000 free queries a month.Fri, 14 Aug 2026 14:30:00 GMTMike Halehttps://stacksmith.xyz/articles/kalshi-market-data-doublezero-edgehttps://stacksmith.xyz/articles/kalshi-market-data-doublezero-edgeKalshi's live order book is now streaming on DoubleZero Edge, making it the first prediction market to distribute market data over a multicast network and the second venue on Edge after Solana. Four feeds went live at launch, covering full L2 depth and top of book across every sports event contract and crypto perps market Kalshi lists, and Kalshi is waiving its revenue share for the first year.Thu, 13 Aug 2026 15:48:00 GMTMike Halehttps://stacksmith.xyz/articles/moneygram-ramps-solana-apihttps://stacksmith.xyz/articles/moneygram-ramps-solana-apiMoneyGram Ramps is now live on Solana, giving developers one API for moving USDC in and out of cash across more than 170 countries and territories. Nearly 500,000 MoneyGram retail locations back the network, and Rift is the first Solana wallet to ship the integration.Wed, 12 Aug 2026 15:54:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-teraswitch-outagehttps://stacksmith.xyz/articles/solana-teraswitch-outageA routing fault at Teraswitch's Miami site knocked 90 Solana validators and about 125 million SOL offline for 33 minutes, pushing delinquent stake to 28.83% against the 33.34% level where the network stops finalizing blocks. Marinade Finance's incident analysis found more than a quarter of all staked SOL concentrated on a single ASN, with 94% of it going dark at once.Wed, 12 Aug 2026 14:04:00 GMTMike Halehttps://stacksmith.xyz/articles/jupiter-lend-v2-smart-vaultshttps://stacksmith.xyz/articles/jupiter-lend-v2-smart-vaultsJupiter has launched Lend v2, letting deposits and borrowed assets earn DEX trading fees on top of their usual yield through two new features, Smart Collateral and Smart Debt. The upgrade runs on Fluid's shared liquidity layer and is designed to put Jupiter Lend's $1.9 billion in deposits to work as active liquidity instead of a static backstop.Mon, 10 Aug 2026 15:06:00 GMTMike Halehttps://stacksmith.xyz/articles/flash-trade-winds-down-solana-perpshttps://stacksmith.xyz/articles/flash-trade-winds-down-solana-perpsFlash Trade is winding down unless it finds a buyer, ending a three-year run as one of the few fully bootstrapped perpetuals exchanges on Solana. Co-founder Anas Khader took full responsibility and gave three reasons for the closure, none of which was running out of money, and any acquisition proceeds go to FAF holders pro rata with the team taking nothing.Sun, 09 Aug 2026 14:52:00 GMTMike Halehttps://stacksmith.xyz/articles/solana-foundation-open-source-tokenshttps://stacksmith.xyz/articles/solana-foundation-open-source-tokensThe Solana Foundation open-sourced Tokens, the codebase behind tokens.xyz, publishing the website, the Assets API, and the internal tooling that tiers each token mint under an MIT license. Tokens covers roughly 300 canonical assets and maps every mint that represents them, so a single Bitcoin page carries cbBTC, WBTC, xBTC, and zenBTC ranked on trading activity rather than pool size alone.Sat, 08 Aug 2026 14:17:00 GMTMike Halehttps://stacksmith.xyz/articles/rarible-solana-marketplacehttps://stacksmith.xyz/articles/rarible-solana-marketplaceRarible launched its Solana NFT marketplace on August 6, 2026, opening with Claynosaurz as its only collection, then added Mad Lads and Dead King Society Nobles on August 10. The launch shipped six days after a RARI DAO vote that had targeted a four-week build.Thu, 06 Aug 2026 16:52:00 GMTMike Halehttps://stacksmith.xyz/articles/hylo-titan-argos-routerhttps://stacksmith.xyz/articles/hylo-titan-argos-routerTitan has integrated Hylo V2 into its Argos router, giving Titan users access to the full Hylo product suite at router-selected prices. Trades hit Hylo's mint and redeem functions directly against the protocol's multi-collateral architecture, covering hyUSD, eHYUSD, xSOL, xBTC, and any future xAssets.Wed, 05 Aug 2026 19:52:00 GMTMike Halehttps://stacksmith.xyz/articles/0x-swap-api-solanahttps://stacksmith.xyz/articles/0x-swap-api-solana0x opened its Swap API on Solana to all developers in beta, giving apps and wallets one endpoint that returns DEX quotes and ready-to-sign swap instructions. Solana is the first non-EVM network 0x has supported, and Kamino and Titan were both routing trades through it during the closed beta.Tue, 04 Aug 2026 20:17:00 GMTMike Halehttps://stacksmith.xyz/articles/kamino-institutional-commodity-yieldhttps://stacksmith.xyz/articles/kamino-institutional-commodity-yieldKamino opened Institutional Commodity Yield, a USDC vault targeting 7% to 8% APY by financing short-term commodity trades instead of lending against crypto collateral. It launched with a $25 million deposit cap, routes capital through a fund supervised by the Cayman Islands Monetary Authority, and publishes the full loan portfolio in the vault UI.Mon, 03 Aug 2026 23:07:00 GMTMike Halehttps://stacksmith.xyz/articles/colosseum-stamp-credible-metadaohttps://stacksmith.xyz/articles/colosseum-stamp-credible-metadaoCredible Finance closed the first ICO ever routed through the Colosseum STAMP, drawing $32,775,016 in commitments from 790 contributors before the team accepted roughly $4 million and refunded the rest. The STAMP replaces the usual SAFE plus token warrant with a single instrument that makes the token the only economic claim, handing the treasury and IP to MetaDAO's decision markets at launch.Thu, 30 Jul 2026 14:04:00 GMTMike Halehttps://stacksmith.xyz/articles/moonpay-paybox-solana-ai-paymentshttps://stacksmith.xyz/articles/moonpay-paybox-solana-ai-paymentsMoonPay has launched PayBox, a non-custodial payment vault that lets Claude and ChatGPT users trade on Solana and pay merchants through plain conversation. Wallet keys are split across hardware-isolated enclaves using MPC from Sodot, so the agent can propose a transaction but a passkey is still required to sign it.Wed, 29 Jul 2026 19:46:00 GMTMike Halehttps://stacksmith.xyz/articles/ramp-stablecoin-payments-solanahttps://stacksmith.xyz/articles/ramp-stablecoin-payments-solanaRamp has opened Stablecoin Accounts and stablecoin Bill Pay to all 70,000+ of its business customers, with Solana among the seven supported networks. Businesses can hold USDC or USDT, pay vendors from that balance, and settle in seconds rather than the three to five days a SWIFT wire takes.Mon, 27 Jul 2026 13:36:00 GMTMike Halehttps://stacksmith.xyz/articles/raydium-permissioned-amm-solanahttps://stacksmith.xyz/articles/raydium-permissioned-amm-solanaRaydium has launched Permissioned AMMs, a new pool type that lets issuers of KYC-gated and regulated assets trade on Solana's deepest liquidity without building a venue of their own. Superstate, an SEC-registered transfer agent, is the first service partner to integrate.Fri, 24 Jul 2026 18:56:00 GMTMike Halehttps://stacksmith.xyz/articles/altitude-accounting-crypto-accounting-automationhttps://stacksmith.xyz/articles/altitude-accounting-crypto-accounting-automationAltitude launched Altitude Accounting, a crypto accounting automation tool that classifies every transaction and syncs it to QuickBooks Online, cutting manual reconciliation at month-end.Wed, 22 Jul 2026 21:47:00 GMTMike Halehttps://stacksmith.xyz/articles/melee-parimutuel-market-maker-pmmhttps://stacksmith.xyz/articles/melee-parimutuel-market-maker-pmmMelee has published the litepaper for its Parimutuel Market Maker (PMM), a Solana liquidity design that gives any prediction market a tradable price from the first dollar, with no professional market makers. Here's how the PMM fixes what broke AMMs, order books, and classic parimutuel pools.Tue, 21 Jul 2026 09:26:00 GMTMike Halehttps://stacksmith.xyz/articles/magicblock-forge-builder-programhttps://stacksmith.xyz/articles/magicblock-forge-builder-programMagicBlock and MonkeFoundry have launched Forge, a VIP builder program pairing Solana founders with 1:1 engineering mentorship, VIP access to ecosystem leaders, and a shot at the IRL Hacker House.Thu, 16 Jul 2026 21:10:00 GMTMike Hale
