Soneium 

What is the Soneium blockchain?

Soneium is a general-purpose Ethereum Layer-2 blockchain built on Optimism's OP Stack and part of the Superchain ecosystem alongside OP Mainnet and Base. Sony Block Solutions Labs — a joint venture of Sony Group Corporation and Startale Group — develops the network, which launched its mainnet in January 2025. Soneium targets consumer applications: entertainment, gaming, IP/NFTs, and finance. DropsTab classifies Soneium as a Layer-2 network, not a tradable coin.

Who built Soneium and when did it launch?

Sony Block Solutions Labs Pte. Ltd. built Soneium. The company is a joint venture between Sony Group Corporation and Singapore-based Startale Group, led by Sota Watanabe, founder of Astar Network. The project was announced on 23 August 2024. Soneium's mainnet launched in January 2025.

How does Soneium's network work?

Soneium operates as an optimistic rollup on the OP Stack, meaning transaction activity is batched off-chain and settled to Ethereum. The network shares the Superchain infrastructure used by OP Mainnet and Base. Network fees on Soneium are paid in bridged ETH, not in a project-specific asset. Development positioning is consumer-first — entertainment, gaming, and IP/NFT applications.

Does Soneium have a token (SONE)?

No. Soneium has no native token — no ticker, no total or maximum supply, and no on-chain token contract exists. No official token announcement has come from Sony or Soneium as of September 2026. The ticker SONE belongs to unrelated projects — S-ONE Finance and an unofficial "soneium (SONE)" DEX listing on Coinbase — while unofficial MetaMask guides label the gas symbol SONE even though official documentation uses ETH. The ticker is unrelated to Soneium — a common confusion point behind searches for "soneium coin" and "sony crypto."

Is there a Soneium airdrop?

No Soneium airdrop has been confirmed. Neither Sony nor Soneium has announced a token distribution, so any page asking users to connect a wallet to "claim SONE" is a scam vector exploiting the Sony brand. Soneium's badge and points campaigns fuel speculation on airdrop-tracking sites, but none of those campaigns constitutes a confirmed token distribution.

What earning campaigns and quests has Soneium run?

Per DropsTab data, Soneium's Activities list records seven campaigns. Five have ended: the Minato testnet (28 August 2024 – 14 January 2025), the OG badge campaign (14 January – 27 February 2025), Soneium Conquest weekly quests on Galxe (29 January – 26 February 2025), the ecosystem badge campaign (7 March – 1 April 2025), and Soneium Score, a proof-of-contribution points program (28 August – 25 September 2025). Rewards took the form of badges, points, and quest completions.

Which Soneium campaigns are listed without an end date?

Per DropsTab data, two Soneium campaigns carry no end date. The Layer3 ecosystem badge campaign launched on 24 March 2025, awarding badges for completing quests and minting "soneium CUBEs." The Soneian Community Program started on Guild on 4 June 2025 and is open to developers, content creators, artists, and community contributors helping grow the Soneium ecosystem.

Who funds Soneium's development?

No VC funding rounds, raise amounts, or valuations have been publicly disclosed for Soneium. Development is financed corporately by the parent companies, Sony Group Corporation and Startale Group, rather than through token-era fundraising. Ecosystem growth runs through Soneium Spark, the project's own incubation program for early-stage teams, launched with the Minato testnet in August 2024.

How do I add Soneium to MetaMask?

Soneium is an EVM-compatible OP Stack chain, so MetaMask supports it as a custom network. Users add Soneium by entering the network parameters — RPC URL and chain ID — published in Soneium's official documentation. Because gas on Soneium is paid in ETH, the wallet also needs bridged ETH on the network before transactions will process.
