Audius

Audius is a decentralized music streaming platform and social network that lets artists publish, distribute, and monetize their music directly to listeners without the labels, aggregators, and payment intermediaries that dominate the traditional streaming industry. Founded in 2018 by Stanford computer science graduates Roneil Rumburg (CEO) and Forrest Browning (CPO), the project raised $16.1 million across five funding rounds from investors including Lightspeed Venture Partners, General Catalyst, Multicoin Capital, and a roster of artist-investors that includes Katy Perry, The Chainsmokers, and Nas.

The Problem Audius Solves

Major streaming platforms typically pay artists fractions of a cent per stream, introduce months-long payment delays through labels and distributors, and give artists little visibility into who is listening or how royalties are calculated. Audius addresses this by replacing the intermediary stack with an open, permissionless protocol where artists upload directly, fans listen for free, and compensation flows on-chain. The platform also treats listener and creator data as public infrastructure rather than proprietary ad-targeting inventory.

How It Works

Audius runs on the Open Audio Protocol, an infrastructure layer the team describes as "the global music database, open and boundaryless." The protocol reached its 1.0 milestone in October 2025, representing the most significant architectural upgrade since the platform launched publicly in 2020. The Open Audio Protocol branding was formalized further in early 2026 as the foundation released tooling for third-party developers and AI agents to build on the same open music infrastructure.

The network is maintained by a decentralized set of validator nodes operated by community members who stake AUDIO tokens as collateral. These validators handle media storage, transaction indexing, and network consensus using a fast Byzantine Fault Tolerant mechanism. Earlier versions of the protocol separated these responsibilities across distinct Content Nodes and Discovery Nodes; the 1.0 redesign consolidated them into a unified validator model that requires a minimum stake of 200,000 AUDIO and rewards operators with approximately 7% annualized returns from the protocol's yearly token issuance.

Solana serves as the execution layer for all on-chain activity related to streaming, payments, and rewards. Five Solana programs underpin the platform's core functions:

• Audius Plays records individual track listening events on-chain, creating a verifiable public record of stream counts.
• Claimable Tokens (User Bank) creates non-custodial SPL token accounts linked to user identities, enabling reward distribution without requiring users to manage private keys through a separate wallet.
• Payment Router distributes SPL-AUDIO and SPL-USDC across multiple recipients in a single transaction, configured by percentage splits—useful for royalty sharing across multiple rights holders.
• Reward Manager validates that users have completed platform challenges, using Discovery Node operator attestations and cryptographic signatures before releasing AUDIO incentives.
• Staking Bridge converts SPL-AUDIO to ERC-20 AUDIO via Wormhole and swaps between SPL-USDC and SPL-AUDIO through Raydium's AMM, linking Solana's fast execution environment to Ethereum's governance layer.

Audius chose Solana to handle the throughput demands of a streaming platform because the network delivers block times of 400 milliseconds and costs roughly $10 per million transactions—economics that make recording every individual stream on-chain viable at scale. As of October 2025, the platform had surpassed 250 million on-chain song streams, a milestone the team marked with a 30 million AUDIO token airdrop distributed to artists and listeners.

Key Features

Free unlimited uploads. Artists can publish their entire back catalog, works in progress, demos, and live sets at no cost, with no storage cap. This stands in contrast to platforms that charge for upload tiers. Uploads support 320kbps streaming and lossless download distribution.

Artist Coins. Launched in October 2025, Artist Coins let verified Audius artists create their own SPL tokens in minutes through the Artist Coin Launchpad. Each coin is paired with AUDIO in an on-chain liquidity pool and is tradeable within the Audius app and across Solana-native DEXes. Artists receive 50% of trading fees generated from their coin's liquidity pool, and 50% of the coin supply unlocks to the artist over a five-year vesting schedule. Holders of an Artist Coin gain access to exclusive music, private Discord channels, in-app badges, leaderboards, and direct messaging from the artist. Early artists to launch coins include Kodak Black ($YAK) and Almighty Jay ($JAY).

DDEX integration. The Open Audio Protocol 1.0 natively supports DDEX, the data format used as the industry standard for music rights and distribution metadata. This enables direct integrations with DistroKid, Warner Chappell Music, Downtown Music, and Kobalt, allowing rights holders to publish to Audius without manual re-entry of metadata. In April 2025, Audius signed a global licensing agreement with Downtown Music, one of the largest independent music companies, adding millions of licensed recordings from Downtown's recording and publishing catalog to the platform.

Developer platform and programmable music. Audius exposes a public REST API and JavaScript SDK, enabling third-party builders to embed its music catalog or build competing streaming applications on top of the same open protocol infrastructure. In February 2026, the team expanded on this with explicit support for programmable music access for AI agents and creative technologists, positioning the Open Audio Protocol as infrastructure for the emerging "vibecoder" and agentic application ecosystem.

Voice AI. In July 2025, Audius partnered with OpenHome to launch a voice AI interface for conversational music discovery, allowing listeners to navigate the catalog through spoken queries.

Remix contests. Artists and labels can run on-platform contests with prize pools. The feature has been used by acts including NGHTMRE, Protohype, Cheat Codes, and Symmetry Festival as part of a major DJ competition launched in 2026.

Feature.fm integration. Since August 2025, artists can connect their Audius releases to smart links and pre-save campaigns managed through Feature.fm, extending distribution reach into mainstream promotional tools.

The AUDIO Token

AUDIO is an SPL token on Solana (bridged from ERC-20 on Ethereum via Wormhole). It serves three functions in the ecosystem: staking collateral for validator node operators, a medium for on-chain payments and rewards within the platform, and a governance mechanism for protocol parameter changes. The protocol emits tokens at a fixed 7% annual rate; node operators who stake AUDIO earn from this issuance as well as from the protocol's aggregated fee pool. Artists with larger AUDIO holdings can unlock premium profile badges that improve content visibility. AUDIO holders also receive 50% of trading fees generated by Artist Coins across the platform. Governance allows token holders to vote on feature integrations, royalty structures, reward allocations, and treasury spending. The Staking Bridge handles cross-chain movement, with the permissionless design allowing any user to move tokens without gated access.

Security History

In July 2022, an attacker exploited an initialization bug in Audius's Ethereum governance contracts—code that had not been actively maintained for nearly two years—and drained approximately 18 million AUDIO tokens from the community treasury. The attacker ultimately realized about $1.08 million after swapping the stolen tokens at depressed prices. The team identified the root cause within an hour and deployed a patch within 87 minutes. The affected contracts had been audited by OpenZeppelin in 2020 and by Kudelski in 2021; neither audit caught the vulnerability. The team published a detailed post-mortem acknowledging that audits are not bulletproof and committed to closer ongoing monitoring of the EVM codebase. The incident did not affect Solana-side infrastructure, which operates separately.

Solana Ecosystem Fit

Audius is one of the longer-standing live consumer applications on Solana, having migrated its content management system to the network in 2021 specifically because Ethereum's throughput and cost structure could not support per-stream on-chain recording at scale. Its Solana programs integrate directly with Raydium (for token swaps), Wormhole (for Ethereum bridging), and the broader SPL token standard. The Artist Coin Launchpad adds a DeFi-adjacent use case—creator token trading with native liquidity—while keeping the experience accessible to users who may not identify as crypto-native. With 250 million on-chain streams, DDEX-based label integrations, and a growing developer ecosystem built on the Open Audio Protocol, Audius represents one of the most sustained real-world uses of Solana's throughput for consumer media. As of mid-2026, the platform remains active with regular artist contests, protocol governance, new feature releases, and ongoing licensing partnerships.
