## @sol_nxxn (nxxn) · 09-20 16:01 · ♥80 ↻14 💬16 That's WHY Solana will be at $300+ this cycle 🐂
1. Ready for anything
- Solana operates with ~250ms block times today and is targeting ~200ms
- The upcoming Alpenglow upgrade targets ~150ms finality, approaching a Web2-level user experience
- Solana routinely processes thousands of transactions per second while maintaining fees measured in fractions of a cent
- Solana processed a record 216M non-vote transactions in a single day in August, and 1.32B in one week
- Median transaction costs are typically below $0.001, making high-frequency trading, payments and consumer applications economically viable at scale
2. ETF inflows
- U.S. Solana ETFs have already attracted roughly $1.34B+ in cumulative net inflows
- ETFs create a regulated channel for pensions, RIAs, hedge funds and traditional investors that cannot directly custody crypto
- ETF inflows create a new source of demand for SOL and increase institutional ownership of the asset.
3. Tokenized stocks
- Tokenized equities are already trading on Solana through platforms and issuers such as xStocks, Backpack, Ondo Global Markets and Kraken, offering exposure to major U.S. stocks and ETFs
- Solana settled approximately $8.8B in tokenized equity trading volume in Q2 2026, up 325% QoQ, and captured roughly 56% of the global tokenized equity market, reaching 70% market share in June alone
- Solana has become the dominant blockchain for tokenized stocks, accounting for approximately 96% of all-time on-chain tokenized equity spot volume, according to ecosystem data
And it's all available 24/7
4. Stablecoins
- More than $16B of stablecoins now circulate on Solana, and monthly volume has repeatedly exceeded $500B–$650B
It seems like it's not just a "casino chain"
5. RWA
- Solana's RWA ecosystem has now passed $4B in value across 350K+ holders/addresses.
This includes tokenized Treasuries, private credit, funds and other traditional financial assets from names like BlackRock, Franklin Templeton, Ondo, Apollo and Hamilton Lane.
6. Inflation problem is being solved
One of the biggest historical bear cases against SOL was token inflation
- Solana's inflation rate has already declined significantly from its original 8% launch rate to roughly 4% today
- The network's long-term target inflation rate is just 1.5%
- New proposals such as SIMD-550 would accelerate disinflation and reduce future SOL emissions by nearly 19M SOL over the coming years
7. Every Crypto Meta Lives on Solana
Whether it’s memecoins, digital collectibles, DeFi, prediction markets, RWAs, stablecoins or the next meta we haven’t seen yet, products increasingly choose Solana
Not only because of the speed and cost , but also because there is deep liquidity, millions of users and god-tier distribution
This creates a powerful network effect: products choose Solana because the users and liquidity are already there, and users choose Solana because the best new products keep launching there and there is easy access to them
8. Institutional adoption
Major institutions are actively building on or integrating with Solana
Participants include BlackRock, Franklin Templeton, Mastercard-linked infrastructure providers, Visa-linked settlement initiatives, MoneyGram, PayPal and Western Union-related payment infrastructure, etc.
Institutions increasingly view Solana as blockchain infrastructure because it makes sense

Solana has always been the fundamental asset of my portfolio, and looking at what's happening now and where crypto is heading, it makes even more sense to me... https://x.com/sol_nxxn/status/2101703391571218640

## @zordcrypt (ZORD CRYPT) · 09-20 17:10 · ♥71 ↻1 💬29 Arc is only four days old, but it already looks different.
We had an influx of launchpads and memes.
But that wasn’t really the main point of Arc mainnet, in case you have forgotten.
@arc launched with BlackRock, Visa, Mastercard, DTCC, ICE, Standard Chartered, Galaxy, MoneyGram, SBI, Sumitomo, Worldpay, and Circle.
They produced the first blocks.
That tells you what @circle is building:
Not just another trading chain as usual.
A dollar-based settlement network institutions could actually use.
✦ What makes @arc different?
Arc is an EVM-compatible Layer 1 that went live on September 16, 2026.
Instead of paying gas with a volatile token, users pay fees in $USDC.
Transactions settle in under a second, blocks don’t reorganize, and the network starts with permissioned validators rather than anonymous operators.
@circle calls it an Economic OS for payments, foreign exchange, lending, tokenized assets, and eventually AI-to-AI payments.
✦ The infrastructure is already here
For a day-one launch, the stack is unusually complete.
→ USDC is native gas, while EURC is already live. → CCTP lets USDC move across more than 20 chains without wrapped tokens. → StableFX handles institutional foreign exchange between stablecoins. → Morpho Blue and Aave V4 launched immediately for lending. → Uniswap and Aerodrome provide trading. → Chainlink supplies price feeds and proof-of-reserves.
Circle also brought USYC, its tokenized Treasury fund, while cirBTC lets Bitcoin holders borrow stablecoins without selling their BTC.
✦ What’s still coming?
Not everything is live yet.
Circle plans to add confidential transactions, expand privacy features, transition toward Proof of Stake in 2027, and activate the $ARC token, which will support staking, governance, and validator incentives.
Importantly, $USDC remains the gas token.
$ARC is not replacing it.
✦ Where is the money actually going?
The interesting part isn’t the validator logos.
It’s where liquidity settled after launch.
Right now, Arc has roughly:
- $628M in stablecoins, almost entirely USDC. - $341M in DeFi TVL. - Around 90% of that TVL sits inside Morpho ($185M) and $Aave ($127M). - Uniswap holds about $24M, while Aerodrome is much smaller.
Shows this isn’t a memecoin-driven launch anymore.
The capital that stayed is sitting inside lending markets.
✦ One caveat
High deposits don’t automatically mean high activity.
Early on, $Aave filled supply quickly, but borrowing remained relatively low.
Some of that liquidity came from institutional partners like Galaxy, Cumberland, Keyrock, and Steakhouse.
The real metric to watch isn’t deposits.
It’s borrow utilization.
If institutions begin borrowing against cirBTC, USYC, and future tokenized funds, Arc starts functioning like the collateral engine Circle designed.
✦ What matters next?
Over the next few months, a few milestones matter more than headline TVL.
• Does BlackRock’s BUIDL arrive and get used as collateral? • Does borrowing on Morpho and Aave increase? • Do Rain, Thunes, Wirex, and Circle Payments Network generate real payment flows? • Does StableFX build meaningful FX liquidity? • Does DTCC’s 2027 tokenization roadmap stay on schedule?
✦ The bigger picture
Arc’s first few days look less like a typical Layer 1 launch and more like financial infrastructure coming online.
The biggest signal isn’t DEX volume.
It’s that liquidity is concentrating around $USDC, lending, and settlement.
For now, @arc looks more like a credit and treasury network than a speculative chain, and that’s exactly what Circle appears to be building. https://x.com/zordcrypt/status/2101720721110290732
## @Kamelkadah99 (Muhammad Kamel Qadah) · 09-20 15:57 · ♥79 ↻6 💬8 (1/2) After the rehearsal came the protocol rail. Protocol 26 completed on Mainnet on August 11. The Docker image for version 27.1.0 was published on August 17. The Protocol 27 Testnet upgrade was announced on August 21, together with the September 15 Mainnet target. Protocol 27 is not a DEX and not an open launchpad. It is the infrastructure the products will need later: contract security, smart-contract authentication, and the foundations of AMM and RPC. That rail is complete as an announcement. The remaining live step is the node fleet moving to 27.1. After September 15, that work was still underway, and the required image remained `organization-mainnet-v1.0-p27.1.0`. A Git tag for version 28 does not mean the products have opened. The organization Mainnet image for that version is unpublished and not required, and the instruction is clear: do not start the move to 28 until the Core Team activates it.
After the nodes comes the product. That is why PIDEX and Launchpad share one working target after activation is stable — not a published promise. The order is rehearsal, then protocol, then nodes, then a public opening. The clock counts down toward the working target. It does not count upward from September 15 as if the opening happened automatically on that day.
This is how a Pioneer can read events without getting pulled into every rumor. A documented fact is locked in. An operational observation is recorded with the date it was seen and is not exaggerated. A rehearsal is respected as proof of a mechanism, not as a market launch. Then the last interval named by the team is measured, a working date is drawn from it, and it is stated plainly that the result is an estimate, not a confirmation. Anyone who follows this method will not confuse “the infrastructure is nearly complete” with “the product opened today,” and will not accept a claim of live Mainnet trading or a live token launch before the primary source says so.
The summary for the community is simple. The main points on the technical path are complete through the protocol rail and the Testnet rehearsals. The public Mainnet opening of PIDEX and Launchpad is still pending. October 20, 2026 is the output of the tracking method, not the output of an official statement. Stay with primary sources. Keep confirmed facts separate from inference. Leave rumor outside the analysis. #PiNetwork #PiDEX #PiRC #Protocol27 #Mainnet #Web3#PiNetwork #PiPioneers #PiMainnet #PiCoreTeam #PiCrypto #PiCommunity #PiDEX #PiLaunchpad #PiNode #PiAI #Protocol27 #Protocol28 #DeFi #Web3 #Decentralization #CryptoNews #DigitalEconomy #FinancialFreedom#DeFi #Web3 #Decentralization #CryptoNews #DigitalEconomy #FinancialFreedom#PiDEX #PiLaunchpad #PiNode #PiAI #Protocol27 #Protocol28 > 引用 @Kamelkadah99: **How we track events in Pi — and why October 20, 2026 appears**
This is not a rumor, and it is not a promise from the Core Team. It is an explanation of the method itself: how facts are collected, how they are sorted, and how a working date can be inferred without mixing what is confirmed with what is only projected.
The first rule of tracking is this: we do not take the story from group chats or second-hand accounts. The only sources used here are what the Core Team published through **@PiCoreTeam**, what appears on the node page at **https://t.co/JJLWT6aADz**, the node protocol upgrade guide, or the **PiCoreTeam/pi-node-docker** repository. Any report claiming that PIDEX is already live on Mainnet was discarded, because it did not come from a primary source.
The second rule is to keep three kinds of evidence separate. They must never be blended.
The first kind is **documented**. That means a date or a sentence the Core Team stated itself. This is how August 11, 2026 entered the record as the Mainnet deadline for Protocol 26, and how September 15, 2026 entered as the stated target for the Protocol 27 Mainnet upgrade. Those two dates are confirmed.
The second kind is **observed**. That means an operational snapshot taken from the node page or a Docker image at the moment of inspection. The snapshot is frozen as it stood on that day. It is not turned into a product-launch announcement. That is why the node page still showing an upgrade to version 27.1 on September 20 does not mean the products have opened. It only means the node rail is still being executed.
The third kind is **rehearsal**. That means Testnet activity proving that a mechanism works. IRRA, SLICE, the order book, and the AMM belong here. A rehearsal proves technical capability. It does not set the Mainnet opening date, and test tokens are not migrated to the live network. The Core Team already said SLICE is a trial token and will not move to Mainnet.
After the evidence is sorted, the measurement begins. In the current sequence, the only interval the Core Team named outright is the distance between the Protocol 26 Mainnet deadline on August 11 and the stated Protocol 27 target on September 15: thirty-five days. We do not invent a gap. We measure the gap the team itself published, then apply the same rhythm after the last announced rail. That produces the working date: September 15 plus 35 days equals October 20, 2026 UTC. This date is called a working target only. It must never be presented as a Core Team confirmation that PIDEX or Launchpad will open on that day.
To understand why the product comes last rather than first, follow the causal order, not the emotional one. What appeared first were the Testnet rehearsals: IRRA on Pi Day, March 14, 2026, with more than 478,000 participants; then the SLICE window from June 11 to June 28; then post-launch tracking on July 24, with order-book matching and AMM pricing proven on Testnet. That stage is complete — complete as training, not as a live market.
