What Is DoubleZero?

DoubleZero is a decentralized physical infrastructure network (DePIN) that builds a private, high-performance fiber backbone for blockchain validators and other latency-sensitive distributed systems. Rather than routing validator traffic over the public internet, DoubleZero stitches together contributed and leased fiber links into a dedicated network (which the project describes as an "N1" layer) that offers lower latency, higher bandwidth, and traffic filtering. Contributors who supply fiber and edge hardware earn the network's native 2Z token, a Solana SPL token.

DoubleZero was built by Malbec Labs, a network engineering firm, together with the DoubleZero Foundation. Its founding team includes Austin Federa, the former head of strategy at the Solana Foundation, alongside Andrew McConnell and Mateo Ward, who bring backgrounds in software and data networking. The project reported raising roughly $28 million at a $400 million valuation from investors including Dragonfly Capital and Multicoin Capital, and it has drawn contributions from teams in the Solana ecosystem such as those working on the Firedancer validator client.

Technically, the network is organized as two conceptual rings. An outer ring of edge devices, including FPGA-based hardware, sits at ingress and egress points where the network meets the public internet; this hardware filters spam, deduplicates transactions, and verifies signatures before traffic enters the core. An inner ring carries the pre-filtered, high-priority traffic across dedicated low-latency fiber between metropolitan interconnection hubs the project calls DoubleZero Exchanges (DZX). By offloading filtering to the edge and reserving private bandwidth for consensus traffic, DoubleZero aims to reduce the noise and jitter that validators otherwise face on the open internet.

Fiber contributors either own their links outright or lease them from telecom providers, and they commit to service-level agreements defined in on-chain smart contracts that specify endpoints, bandwidth, latency targets, and packet handling. The protocol monitors compliance, and links that fail to meet their commitments can lose rewards or be removed. Validators and other users connect through these contracts and pay for the connectivity they consume, while contributors are compensated in 2Z based on the demand their capacity serves.

The 2Z token is the network's coordination and payment asset, issued on Solana using the SPL token standard. It has a maximum supply of 10 billion tokens and a total supply near 9.998 billion, of which roughly 3.47 billion (about 35 percent) were in circulation as of mid-2026, giving a market capitalization of roughly $254 million. Because a large share of the supply remains locked, future unlocks are a source of potential dilution. Malbec Labs, for example, was reported to hold about 14 percent of the supply vesting over four years.

Ahead of its launch, DoubleZero received a no-action letter from the U.S. Securities and Exchange Commission, dated late September 2025. In it, SEC staff indicated they would not recommend enforcement action if 2Z is distributed programmatically as described, and that on this basis the token would not need to be registered as a security. It was widely reported as the SEC's first no-action letter to a crypto project since 2020 and a notable data point for DePIN regulation. The relief is narrow, however: it is staff guidance tied to the specific facts and distribution method presented, not a blanket ruling that 2Z can never be treated as a security.

By its mainnet-beta launch, DoubleZero reported operating dozens of high-capacity fiber routes across roughly two dozen cities, and it has said that a meaningful portion of Solana's mainnet stake weight was already routing traffic through its network. The project has continued to add products on top of the backbone, including a low-latency onchain data delivery service branded Edge. As with any early-stage DePIN, the long-term case depends on sustained, paid usage of the underlying network.

Getting Started With DoubleZero

You can engage with DoubleZero as a token holder, a network contributor, or a validator or application that consumes its connectivity:

  1. Step 1: Set up a Solana wallet such as Phantom or Solflare and back up the seed phrase. This holds 2Z, which is an SPL token on Solana.
  2. Step 2: Acquire 2Z on a supported exchange and withdraw it to your Solana wallet, or earn it by contributing infrastructure to the network.
  3. Step 3: To contribute, review the DoubleZero documentation on running edge hardware or supplying fiber links, and register your resources through the protocol's on-chain service agreements.
  4. Step 4: To use the network, follow the docs to connect a validator or application and pay for the low-latency connectivity you consume.

How to Get a DoubleZero Wallet?

2Z is a Solana SPL token, so any Solana-compatible wallet can hold and manage it. The following are common choices:

Phantom

Phantom is the most widely used Solana wallet, available as a mobile app and browser extension. It supports 2Z and other SPL tokens out of the box and connects easily to Solana DEXs.

Solflare

Solflare is another popular Solana wallet with strong staking and hardware-wallet integrations. It supports SPL tokens including 2Z and works on both mobile and desktop.

Backpack

Backpack is a Solana-native wallet and exchange interface that supports SPL tokens and is a convenient option if you already use the Backpack ecosystem.

Hardware Wallets

Ledger devices support Solana SPL tokens through the Solana Ledger app and can be paired with Phantom or Solflare to keep keys offline for larger balances.

How to Buy DoubleZero?

2Z listed on several major venues around its October 2025 launch. You can buy it on centralized exchanges or swap for it on Solana decentralized exchanges:

Centralized Exchanges

2Z is available on exchanges including Binance, Bybit, and Upbit, among others. Common pairs are quoted against USDT. Availability and pairs vary by region and can change over time.

Decentralized Exchanges

Because 2Z is a Solana SPL token, it can be swapped on Solana DEXs such as Jupiter, Orca, and Raydium. Jupiter is the standard aggregator and routes across the deepest pools automatically. When swapping, verify you are using the correct 2Z contract address (J6pQQ3FAcJQeWPPGppWRb4nM8jU3wLyYbRrLh7feMfvd) to avoid imposter tokens.

Latest DoubleZero News

The defining recent events for DoubleZero were its late-September 2025 SEC no-action letter and the October 2, 2025 mainnet-beta launch, which coincided with the 2Z token generation event and simultaneous listings on multiple large exchanges. The token reached its all-time high around the launch date and has traded well below that level since. The decline drew public criticism of the token distribution, with some commentators accusing the team of setting up a "rug," a characterization the founder publicly rejected by pointing out that team and investor allocations are locked and vesting. The dispute was one of narrative rather than any proven wrongdoing, but it is part of the token's early history, and steep post-launch drops are common for tokens that debut with only a fraction of supply circulating.

Since launch, DoubleZero has continued expanding its fiber footprint and shipping products on top of the backbone, including Edge, a low-latency onchain data delivery service. As an early-stage DePIN with a large locked supply and scheduled future unlocks, its trajectory depends on growing real, paid usage of the network and on how the broader validator community adopts its connectivity. Following the DoubleZero blog, documentation, and on-chain metrics is the best way to track progress.
