Upbit has confirmed the listing of MPLX and NEX, bringing two infrastructure-focused crypto assets to South Korea's largest exchange. Metaplex's MPLX will trade in BTC and USDT pairs on the Solana network, while Nexus's NEX will open in a USDT pair on the Ethereum network. The listing places both tokens in front of one of the world's most active retail crypto markets, with the source article citing $40 billion in trading volume during Q1 2026.
Metaplex arrives on Upbit with deep ties to Solana issuance infrastructure
Metaplex is widely used as the standard for launching tokens and NFTs on Solana. According to the source material, its infrastructure has been used to create 99% of all tokens and NFTs on the network. It has also supported the creation of more than 900 million digital assets and processed over $10 billion in cumulative transaction value.
The MPLX token has a direct link to protocol activity through buybacks. The Metaplex DAO allocates 50% of monthly protocol revenue to buying MPLX on the open market, and accumulated buybacks have brought DAO holdings to roughly 23% of total supply. Over the past year, monthly protocol fees ranged from $1.1 million to $2.5 million. MPLX has a total supply of 1 billion tokens, all fully unlocked as of 2025, with around 523 million currently in circulation.
The protocol has also expanded its product set. Genesis, an anti-MEV launchpad introduced in mid-2025, added a revenue stream tied to token launches. In early 2026, a governance proposal to add AI Agent identity capabilities to Metaplex Core NFTs passed. The self-service Metaplex App launched in February 2026, giving projects without full development teams a way to launch tokens on Solana.
Nexus uses a zero-knowledge design for verifiable finance
Nexus is positioned as a Layer 1 built for what the team calls verifiable finance. The idea is that core financial actions such as matching and liquidations should be cryptographically provable instead of trust-based. Its architecture runs on a zero-knowledge virtual machine, where every calculation can produce a mathematical proof of correct execution.
The Nexus mainnet launched on April 21, 2026 alongside the NEX Token Generation Event. KuCoin listed NEX on May 20, followed by WEEX on May 25. Upbit now gives the token its first direct access to South Korea's retail investor base. The roadmap in the source highlights two upcoming milestones: USDX, a stablecoin backed 1:1 by US Treasury bills through a partnership with M0 Protocol and targeted for mid-2026; and Nexus Exchange, a protocol-level central limit order book for spot and perpetual futures trading.
For exchange listing purposes, NEX trades as an ERC-20 token on Ethereum. The project raised $27.2 million across seed and Series A rounds from Lightspeed Venture Partners, Pantera Capital, Dragonfly Capital, and Faction. Total supply is capped at 100 trillion tokens. The project is led by CEO Daniel Marin, formerly of Google and a Stanford graduate, alongside Chief Scientist Jens Groth, previously research director at DFINITY.
Two different infrastructure narratives meet the Korean market
The dual listing brings two separate segments of crypto infrastructure onto Upbit. MPLX represents the asset issuance layer inside the Solana ecosystem, while NEX is tied to a Layer 1 thesis built around verifiable financial execution and an onchain order book model.
For MPLX, the listing comes with a token model already linked to protocol fee generation and buybacks. For NEX, the timing places the asset on a major Korean exchange before its exchange product reaches market. The source also notes a common listing pattern: major exchange additions often trigger short-term trading volume spikes, followed by a consolidation phase tied more closely to actual adoption. It also states that such projections remain speculative and are not guaranteed outcomes.
