Jito BAM preconfirmations go live on Solana, covering 34% of network stake.

Jito BAM preconfirmations go live on Solana, covering 34% of network stake. Jito BAM preconfirmations launched September 9 on Solana mainnet, covering Jito JTO$0.432-1.4% activated preconfirmations for its Block Assembly Marketplace on Solana mainnet on September 9, routing early transaction signals to traders through distribution partners Helius hSOL$118.56-2.3% and Triton One. At launch, BAM-compatible validators account for 34.1% of all staked SOL across 383 of 665 active validators, per SolanaFloor. The launch opens a new fee stream for those validators, with first distributions scheduled for October 2026. Keep up to date with the Solana eco BAM validator share Jito DAO treasury share Distribution partner share How BAM preconfirmation revenue flows to validators and the DAO. Revenue from preconfirmation subscriptions splits three ways, per CryptoBriefing: 35% to participating validators by stake weight, 35% to the Jito DAO treasury, and 30% to the infrastructure providers routing streams to subscribers. Helius and Triton One share that 30% as launch distribution partners. The DAO treasury allocation is governed by holders of the JTO... token. Rewards are paid monthly as stake-weighted priority fees. Enforcement is mechanical. A BAM Verifier monitors each finalized block against the preconfirmation commitments the validator broadcast. Validators whose blocks deviate from those commitments face network disconnection. Over the 30 days ending September 10, Jito's block engine tips averaged roughly 1,500 SOL per day, per Solana Compass fee analytics. BAM preconfirmation fees beginning in October will supplement that existing tip revenue. What AgaveBAM and FireBAM Require, and the 5-10ms Latency Advantage. Validators running the Jito-Solana client join by adding a -bam-url flag; those running Firedancer participate through the FireBAM client. No hardware changes are required, and the BAM documentation notes that JitoSOL... rankings and vote credits are unaffected provided validators avoid downtime. For subscribers, BAM signals arrive after a validator has scheduled a transaction but before it is packed into entries and shreds. Early testing showed a 5-10ms advantage at the p50 latency mark versus shred-based signals, the window high-frequency strategies depend on for execution edge. As Helius's preconfirmations documentation makes clear, a preconfirmation is an early signal rather than a guarantee: a scheduled transaction has not yet landed on-chain and could still fail or be dropped. BAM uses Trusted Execution Environments as hardware enclaves to handle transaction sequencing separately from validator execution, letting the network verify that sequencing commitments were not altered before a block is built. Jito CEO Lucas Bruder told SolanaFloor the system "consistently offers the highest compute units and user transactions per block" compared with rival clients. BAM stake share grew from 12% to 34% through 2026. BAM adoption among validators climbed steadily before preconfirmation revenue went live. Coverage stood at roughly 12% of network stake in January 2026 and reached 34.1% by September 9, per SolanaFloor. An early mainnet phase ran for approximately a year before payouts activated, giving validators time to migrate ahead of any revenue incentive. The preconfirmations rollout follows the Q2 2026 activation of BAM's Maker Priority Plugin, a separate product on the same client stack. MPP had 17 operators at launch, including BisonFi, Tessera, and SolFi. Jito's development roadmap lists expanding MPP to additional markets and introducing intra-slot clock mechanisms to counter toxic order flow. Bruder previewed the BAM architecture in a December 2024 Lightspeed podcast and presented the system at Breakpoint 2025.

Helius open-sources rpc-perf-dash, a global Solana RPC benchmark with anti-gaming safeguards.

Helius open-sources rpc-perf-dash, a global Solana RPC benchmark with anti-gaming safeguards. Helius open-sourced rpc-perf-dash on July 22: a continuous Solana RPC benchmark across six global regions that uses randomized inputs to prevent provider gaming Helius hSOL$87.58+0.8% released rpc-perf-dash on July 22, an open-source system that runs continuous benchmarks against public Solana RPC providers across six global regions. Helius engineer Nick Pennie announced the tool on X that day, calling out existing benchmarks as "horribly flawed" for being non-global, running over home internet connections, ignoring tail latencies, omitting freshness and correctness checks, and cherry-picking time ranges. Keep up to date with the Solana eco The repository is licensed under Apache-2.0 and accepts community contributions. A live dashboard at helius.dev/benchmarks displays rolling results; the system collected more than 35 million samples in the 24 hours preceding publication. Why existing Solana RPC benchmarks fall short. The core problem with provider-published benchmarks is that providers can optimize their services specifically for known test inputs, producing numbers that do not reflect real application behavior. When benchmark parameters are predictable, results can be engineered rather than earned. rpc-perf-dash uses a commit-reveal scheme to address this. Before each challenge round, the system draws its parameters from live Solana chain state and commits to them under a hidden seed. That seed stays concealed until the challenge's time-to-live expires, so providers receive no advance view of the test inputs. After each round, anyone can verify that the parameters were fixed before responses arrived. Correctness is established by majority-vote consensus across all provider responses for each challenge. Scoring formulas, consensus rules, and eligibility thresholds are documented in docs/methodology.md within the repository. 45 methods tested across six regions and four cloud providers. Per the repository, the benchmark tests approximately 45 RPC methods covering block and transaction lookups, account and token reads, and chain-metadata calls. Challenges run from six regions across four cloud providers (TSW, AWS, GCP, and Cloudflare), spanning US, EU, and APAC zones. Per the benchmark's default scoring, each provider is graded on five weighted dimensions: latency at p50 and p95 (25%), win rate measured as the share of rounds where a provider returned the fastest correct response (25%), cross-region reliability (25%), data correctness (20%), and data freshness (5%). The weights are user-configurable, so teams prioritizing latency for trading applications can score differently from teams where correctness takes precedence. Freshness is scored separately from correctness. A response can be accurate but stale, which rpc-perf-dash treats as a distinct failure mode relevant to any application reading real-time chain state. Current rankings on the benchmark dashboard. As of July 24, the dashboard ranked four providers against the default scoring weights. Helius led with 91.2 out of 100, ahead of QuickNode at 85.1, Triton at 78.6, and Alchemy at 70.4, per the dashboard. 91.2 / 100 85.1 / 100 78.6 / 100 70.4 / 100 Helius built rpc-perf-dash and currently ranks first in it. The open-source design and the self-run option are the primary checks on that conflict: the repository is public, the methodology is documented, and anyone can clone the project and produce independent measurements. How to add providers and verify results independently. The system is designed to add providers beyond the four it currently tracks; the README notes that additional providers can be included via configuration. Nathan Liow, who contributed to the project alongside Pennie, wrote on X that the goal is for the tool to "keep rpc providers accountable and accelerate the Solana ecosystem." Helius has been expanding its developer tooling in 2026. In June, the team launched the balance-at API, which lets developers query any Solana wallet's historical SOL or token balance at a past timestamp in a single call.

Solana Research Institute.

Solana Research Institute. Helius joins the Solana Research Institute as Founding Member. April 30, 2026 Helius Blockchain Technologies, Inc. has joined the Solana Research Institute (SRI) as a Founding Member, and are proud to share the SRI's inaugural research piece: A Financial Institution's Guide to Solana. As a Founding Member of the SRI alongside Solana Foundation, Jito, R3, and other ecosystem partners, Helius Blockchain Technologies, Inc. is committed to advancing rigorous, institutional research as public stewards of the Solana network. The Solana Research Institute is a Swiss-based, not-for-profit applied research forum dedicated to examining how financial institutions can participate in blockchain-based financial systems. Founded by Angus Scott - formerly Head of Innovation at Euroclear and Head of Product at CLS - and seeded by the Solana Foundation, the SRI provides systematic analysis of onchain infrastructure, evaluating the transition from legacy frameworks to high-performance capital markets. The Institute brings together practitioners from traditional finance and the Solana ecosystem through research, structured discussions, and working groups. The SRI's focus covers the technical, legal, economic, and structural questions that will determine how the transition to blockchain-based rails for trading and payments will unfold. Critically, the Solana Research Institute is not an advocacy organization. Its editorial stance places equal weight on performance data and institutional adoption as it does on stability concerns, concentration risks, regulatory gaps, and areas of improvement across the ecosystem. This rigor and integrity are the point. Financial institutions will only trust analyses that treat the hard questions seriously. The SRI is built to meet this bar. The case for Solana at an institutional scale is no longer theoretical. USDC on Solana circulates 15.5x faster than on Ethereum. BlackRock, State Street, Franklin Templeton, Visa, and Fidelity all have live deployments on the network. The protocol has maintained 100% uptime since February 2024, and Alpenglow is set to bring finality down to 150ms - a latency profile that is becoming competitive with traditional market infrastructure. The regulatory picture is also shifting: * SOL, the native asset on the Solana blockchain, has been officially classified as a digital commodity by the SEC and the CFTC. * The Genius Act has provided long-needed clarity for stablecoin issuance in the United States. * The Eurosystem's Appia Roadmap signals that public-chain participation is now on the agenda of central bank planners. What has been missing is a structured resource that meets senior practitioners inside financial institutions on their own terms. The Solana Research Institute's first publication, A Financial Institution's Guide to Solana, is neither a whitepaper nor a promotional piece. It is a practical reference covering Solana's technology, economics, governance, regulatory context, and the institutional products already live on the network, written in clear, accessible language. Helius Blockchain Technologies, Inc. believe it will become the standard onboarding reference for banks, asset managers, market infrastructure providers, and regulators engaging with Solana for the first time. Solana is the most battle-tested and scalable blockchain network in existence today that is capable of supporting the global demand for onchain trading, payments, and emerging digital asset use cases. As one of Solana's leading infrastructure providers and publishers of technical content, Helius Blockchain Technologies, Inc. is uniquely positioned to help shape the institutional adoption of Solana. Helius Blockchain Technologies, Inc. operate the RPC nodes, data streaming services, and transaction landing infrastructure that Solana's most influential teams, including Phantom, Jupiter, and Coinbase, depend on. In addition to running one of the largest validators on Solana ourselves, Helius Blockchain Technologies, Inc. is trusted to run SOC 2 Type II compliant validators for institutions like Bitwise, which operates the largest Solana Staking ETF to date. Because Helius Blockchain Technologies, Inc. is exclusively focused on serving Solana, Helius Blockchain Technologies, Inc. has a unique perspective and depth of knowledge on how to meet the security, compliance, and operational requirements of institutions. This experience enables Helius Blockchain Technologies, Inc. to meaningfully contribute to institutional conversations regarding Solana's technology, economics, and more. From day one, Helius Blockchain Technologies, Inc. believed that Solana's growth depended on education. Helius Blockchain Technologies, Inc. has spent years building one of the most comprehensive bodies of public writing on the network and, in doing so, have become one of the leading publishers of Solana research and developer content. From institutional and protocol-level research reports to developer tutorials, interviews with core contributors, and cultural essays on the philosophical and sociocultural foundations underpinning blockchain technology, there are few topics Helius Blockchain Technologies, Inc. haven't covered. Its work is read by builders, validators, institutional analysts, policy makers, and has even been cited by the White House. Joining a research body that aligns with its commitment to academic rigor and its desire to present the institutional case for Solana is a natural extension of the work Helius Blockchain Technologies, Inc. has been doing for years. Its commitment to Solana and its builders has never wavered. As Solana enters a new era of mainstream growth, Helius Blockchain Technologies, Inc. is doubling down. Solana's success as institutional financial infrastructure depends on the quality of the discourse around it, the depth of analysis available to decision-makers, and the willingness of the ecosystem's core participants to responsibly steward the protocol in public. The Solana Research Institute is where that hard work happens, and Helius Blockchain Technologies, Inc. look forward to being part of it. Table of Contents

Introducing Token Account Filters for gTFA

Introducing token account filters for gTFA. Last October Helius Blockchain Technologies, Inc. released getTransactionsForAddress, a new Solana RPC call for querying historical data that combines getSignaturesForAddress and getTransaction into one method. Today, Helius Blockchain Technologies, Inc. is excited to announce getTransactionsForAddress (gTFA) can now query a wallet's token transfer history with a single RPC call. The new tokenAccounts feature allows users to include transactions for the wallet's associated token accounts - previously omitted from gTFA and its predecessor, getSignaturesForAddress. Before, developers were forced to query getTokenAccountsByOwner and then getSignaturesForAddress for every token account. This was slow and expensive, often requiring 100s of extra RPC calls. Now, it only takes a single call to getTransactionsForAddress with tokenAccounts. On Solana, your wallet doesn't actually hold tokens directly. Instead, your wallet owns Associated Token Accounts (ATAs), and those token accounts hold your tokens. For example, when someone sends you USDC, it goes to your USDC token account instead of your main wallet address. This creates a major headache when querying wallet transaction history: When you call getSignaturesForAddress on a wallet, you only get transactions that directly reference that wallet address. Token transfers that interact with your token accounts - but don't mention your wallet - simply don't show up. Before today, developers had to implement a tedious workaround: * Call getTokenAccountsByOwner to get token accounts for a wallet * Call getSignaturesForAddress for the wallet itself * Call getSignaturesForAddress for every single token account * Merge all results together * Deduplicate (many transactions touch multiple accounts) * Sort chronologically A wallet with 50 token accounts requires 51+ RPC calls just to build a complete history. Professional traders, heavy DeFi users, or recreational memecoin traders can have hundreds of token accounts. Want the 20 most recent transactions? You can't just fetch 20 from each source and merge - you need to fetch everything, dedupe, sort, and only then take the first 20 transactions. There's no way to efficiently paginate without over-fetching. Each RPC call has overhead. Multiplying that overhead by 100+ calls per user request gets expensive fast, especially at scale. With the new tokenAccounts filter, you can get a complete wallet history in a single RPC request: The tokenAccounts filter provides three options: none, balanceChanged, and all. When the tokenAccounts filter is set to none, transactions must reference the wallet address. When balanceChanged is applied, transactions reference the wallet address, or modify the balance of a tokenAccount owned by the wallet. Setting tokenAccounts to all requires that transactions reference the address of the wallet or a token account owned by the wallet. * Wallets showing complete transaction history * Portfolio trackers that need every token movement * Tax software calculating gains/losses across all tokens * Analytics dashboards displaying user activity Simply add tokenAccounts: balanceChanged (or all) to your filters object and you're set!
