How will adoption of blockchain primitives and infrastructure such as stable coins, payment rails like Tempo, and decentralized exchanges like Hyperliquid affect the future?

As of September 24, 2026, the evidence points to three different adoption curves. Stablecoin supply and transfer activity are already large, but payments remain a minority of measured activity. Specialized payment rails are moving from testnet experimentation to production infrastructure. Perpetual-futures DEXs have demonstrated that a non-custodial venue can attract significant volume, but their economics remain highly sensitive to crypto-market activity, liquidity, token incentives and governance.

The important distinction: dollar liquidity is not the same as payment adoption

A February 2026 industry report measured $266.3 billion of circulating stablecoins, $11.6 trillion of adjusted transfer volume in 2025, and $393.5 billion of labeled payment volume across 540.7 million transactions. The same report says payment volume was approximately 4% of entity-adjusted volume and cautions that this is a lower bound because wallet labeling is incomplete. [1]

That distinction changes the investment interpretation. Stablecoins already have meaningful utility as crypto-market collateral, exchange settlement, cross-border liquidity and digital-dollar savings. Those use cases create demand for issuance, custody, trading and compliance even when no merchant accepts a stablecoin at checkout. Payment adoption is real but earlier-stage: business-to-business activity represented 35% of payment volume, while B2B plus consumer-to-business represented 52%. The report also identifies a decline in average consumer-to-business ticket size from $614 to $454, consistent with more frequent, smaller transactions. [1]

A separate September 2026 estimate put stablecoin payments at $401–527 billion in the first eight months of 2026, up 42–63% year over year. The range itself is informative: adoption is accelerating, but measurement remains methodology-dependent. [2]

Where the money flows

3. Payment networks may preserve the customer relationship

Visa's April 2026 announcement said its stablecoin settlement pilot supported nine blockchains and reached a $7 billion annualized settlement run rate, up 50% from the prior quarter. Visa added Arc, Base, Canton, Polygon and Tempo while continuing to leverage Avalanche, Ethereum, Solana and Stellar. [6]

Visa's strategic advantage is distribution and trust rather than control of one chain. Its stablecoin products include cards, settlement, cross-border movement and developer tools. [7] Mastercard likewise announced support for settlement using regulated stablecoins including USDC. [8] If these networks abstract away chain selection for issuers, acquirers and merchants, the rail may become an input while the network retains the customer interface, compliance relationships and acceptance footprint.

Tempo: the rail becomes a product, not just blockspace

Tempo's mainnet went live on March 18, 2026. Its launch introduced the Machine Payments Protocol, an open standard co-authored by Stripe and Tempo, with an explicit design goal of supporting machine payments across stablecoins, cards and other payment methods. Tempo said it was working with partners including Mastercard, Visa, Shopify, Revolut, Standard Chartered, DoorDash and others on real payment workloads. [9]

The design is economically relevant because it removes several frictions that make general-purpose chains awkward for payments. Tempo has no native token; transaction fees can be paid directly in supported USD stablecoins. Its documentation gives a base-fee cap of about $0.0006 for a 50,000-gas transfer, with fees accruing to the validator that proposes the block. [10]

TIP-20 adds payment-specific functionality such as fee payment, reserved payment lanes, transfer memos and compliance policies. The performance page describes final settlement in about half a second, reserved blockspace for payments and a TIP-20 transfer staying under $0.001 regardless of network load. These are documented product and design claims, not evidence that Tempo has already won material payment volume. [11] The missing variable is adoption: throughput is valuable only if wallets, issuers, merchants, processors and developers route transactions through the rail.

Hyperliquid: proof that trading can migrate onchain, with a different risk profile

Hyperliquid's official site markets more than 300 perpetual and spot markets that are fully onchain and non-custodial, spanning crypto, commodities, indices, foreign exchange and real-world assets. [12] VanEck reported $633 billion of Hyperliquid trading volume in Q1 2026 and approximately 32% of onchain perpetual-futures volume. [13]

Third-party dashboard data available in the research set showed $63.29 million of fees and $47.41 million of protocol revenue over a recent 30-day window, with annualized rates of $959.58 million and $721.16 million respectively. The same dashboard attributed 99% of perps fees, excluding builder fees, to the Assistance Fund for HYPE purchases. These are annualized dashboard observations, not audited public-company earnings, and should not be treated as a stable run rate. [14]

The mechanism is different from payments. A DEX earns when traders turn over notional, and liquidity providers, validators, builders and token holders divide the economics. The strongest advantage is product-market fit: users may accept non-custodial settlement when liquidity, execution and market breadth are good enough. The strongest weakness is cyclicality. A fall in volatility, open interest or incentive-supported liquidity can reduce fees quickly, even if the technology remains competitive. Hyperliquid's official fee documentation says fees are based on rolling 14-day volume and assessed daily, reinforcing that activity—not merely installed infrastructure—drives revenue. [15]

The bottleneck is distribution, compliance and credible settlement

Technical performance is no longer the only constraint. A payment rail must offer reliable redemption, fraud controls, sanctions screening, wallet recovery, accounting, customer support and integration into existing merchant and treasury systems. Stablecoin frameworks also differ on who may issue, which activities issuers may conduct and whether restrictions apply only to the issuer or the broader corporate group. The BIS notes that issuance regimes generally focus on issuance, redemption and reserve management, while additional activities such as lending, staking or custody can change the risk profile. [16]

The regulatory question has direct economic consequences. If issuers are tightly constrained, banks and regulated payment networks may gain relative advantage because they already possess compliance and distribution infrastructure. If rules permit well-capitalized nonbanks to compete broadly, stablecoin issuers and specialized rails may take more share from legacy payment intermediaries.

Bank disintermediation is a second-order risk that matters to the long-term equilibrium. Federal Reserve analysis says domestic substitution of bank deposits into stablecoins may reduce bank deposits and leave banks with more concentrated, uninsured wholesale funding; it also says stablecoins could weaken the historical linkage between payments and lending. [17] The ECB similarly identifies loss of confidence in par redemption as a trigger for a run and depegging, while noting that euro-area risks were still limited at the time of its analysis. [18]

Listed-company exposure

Hyperliquid and Tempo are not currently treated as listed-equity picks in this report. Their infrastructure and token economics may be economically important, but forcing them into a conventional stock comparison would confuse protocol exposure with ownership of a public company's cash flows.

What would change the thesis

The constructive case strengthens if labeled payment volume continues to grow faster than speculative transfer volume; business wallets and merchant settlement become repeatable rather than episodic; Visa, Mastercard and similar networks disclose sustained settlement growth; and Tempo publishes evidence of real production throughput and recurring enterprise usage. For Hyperliquid, the decisive evidence would be resilient fees and protocol revenue through a weaker crypto market, without relying on unsustainable token incentives.

The thesis weakens if payment activity remains a small fraction of adjusted volume, users treat stablecoins mainly as exchange collateral, reserve or redemption concerns produce a sustained depeg, regulation limits nonbank distribution, or payment rails compete fees down faster than they create new volume. For the stocks, the practical monitoring list is USDC circulation and reserve-income sensitivity for CRCL; stablecoin revenue, average balances and partnership economics for COIN; and Visa's disclosed stablecoin settlement volume and monetization for V.
