Stablecoins move from fast transfers to real-world rails
a16z points to stablecoins hitting an estimated $46 trillion in annual transaction volume, a scale that forces the conversation to change. The question is no longer whether stablecoins work. The question is how they plug into the systems people already use every day.
The missing piece is still onramps and offramps, not speed onchain. Sending a stablecoin can already be near-instant and near-free. What is still hard is moving between local money and digital dollars without friction, without confusing UX, and without slow compliance workflows.
The next wave, in a16z’s framing, is a set of companies that connect stablecoins to familiar payment rails. Think QR-based local payments, real-time bank transfers, wallet layers that feel global by default, and card issuing that makes spending stablecoins feel routine. If that link becomes boring and reliable, stablecoins stop being a niche tool and become a base layer for online payments.
In parallel, the firm argues tokenization needs to stop copying TradFi formats. Simply putting “the same asset, now as a token” is not the full story. Crypto-native markets often prefer simpler, deeper-liquidity instruments, especially perpetual futures. The phrase used is “perpification vs tokenization,” a way to say that onchain access might scale faster through derivatives that already fit crypto’s market structure.
The same critique shows up in credit. Stablecoins backed only by safe reserves can resemble narrow banks. That model can work, but it may not support a larger onchain economy without stronger credit rails. a16z’s push here is toward origination, not just wrapping. Debt that starts onchain can cut operational cost and widen access, but it also runs directly into compliance and standardization work that builders must solve.
Agents shift the bottleneck from intelligence to identity
a16z’s agent thesis is blunt: the bottleneck moves from how smart the software is to whether the software can be trusted to act. In financial systems, non-human identities already outnumber humans by a wide margin, yet they are still “ghost users” from a banking perspective.
That is where “Know Your Agent” comes in. The idea is not marketing. It is a practical requirement: an agent needs cryptographically signed credentials that tie it to a principal, set clear constraints, and define liability. Without that, merchants and platforms will keep blocking automated actors, even if those agents are competent.
The piece also links agents to payments. If more commerce becomes background automation rather than explicit user clicks, then value transfer must become as programmable as information transfer. The text highlights emerging payment primitives like x402 as an example of how software could pay software for data, compute, or APIs without the usual invoicing and reconciliation overhead.
In that world, payment is not a separate business process layered on top of apps. It becomes a built-in network behavior. That is the core reason stablecoins show up everywhere in this outlook. They are not just a “crypto product.” They are a shortcut around slow bank ledger upgrades, allowing institutions to ship new behavior without rewriting decades-old core systems.
Privacy and verifiable security become the real differentiators
a16z argues privacy is the missing feature for finance moving onchain at scale. Many chains can compete on performance, but few can offer privacy as a default capability. And once privacy exists, it can create a stronger kind of lock-in because moving private activity across boundaries is risky.
The text makes the point simply: moving tokens is easy, moving secrets is hard. As soon as transaction data and metadata matter, users become cautious about leaving a private zone. That caution can turn privacy into a defensible moat, especially if fees compress toward zero and “general purpose chains” look similar.
On security, the piece pushes a shift in mindset: from “code is law” to “spec is law.” The claim is that mature systems should not rely on case-by-case audits and pattern matching alone. They should define global safety properties and enforce them, both before deployment and at runtime.
AI-assisted tools may help write specs and invariants, but the end goal is more basic: if a transaction violates a core safety rule, the system should automatically reject it. This is framed as a practical way to stop entire classes of exploits, even novel ones, because the guardrails are enforced during execution.
The outlook also flags proofs getting cheaper and smaller. zkVM proving overhead is described as moving toward a range that can run broadly, even approaching real-time proof generation with GPU help. If that happens, “verifiable cloud compute” becomes more realistic: you can outsource CPU workloads and get a proof they ran correctly without re-running them yourself.
Building in 2026 means resisting the trading-only trap
One of the sharper builder warnings is about the industry’s habit of pivoting into trading the moment it works. Trading can look like instant product-market fit, but it also pulls teams into the same crowded lane and can drain time from building a durable product with a clearer edge.
The policy angle is also central. The piece argues that clearer market structure rules in the U.S. could change incentives away from ambiguity and toward transparency. The promise is not that regulation is “good,” but that predictable rules reduce the need for legal contortions that distort token design, governance, and distribution.
Put together, the a16z 2026 view is coherent: stablecoins become the money rail, agents force identity upgrades, privacy becomes a moat, and security becomes more like engineering discipline than folklore. The opportunity is not a single narrative. It is the merge of payments, identity, and verifiability into systems that feel normal to users.
