Wallet-native attribution
A SIWE signature proves the connected wallet approved the claim. That makes an audio proof portable across apps, marketplaces, and communities that already understand Ethereum wallets.

About SonoSig
SonoSig helps creators attach wallet-signed provenance to audio files, making attribution easier to verify as music moves across collaborators, platforms, and licensing workflows.
Read the FAQAudio provenance
Audio provenance, signed by your wallet.
SonoSig helps creators attach a verifiable wallet claim to audio so attribution can survive ordinary sharing, exports, and platform changes.
Proof travels with the audio
SonoSig encodes proof data into the audio output instead of relying only on filenames, ID3 tags, or platform metadata that can be stripped during upload, export, or sharing.
Tamper-evident verification
Verification can compare the embedded proof with the signed wallet message and audio fingerprint. If the file or claim changes, the proof should no longer match.
Client-side privacy
Encoding and verification run in the browser. Your source audio does not need to be uploaded just to create or inspect a proof.
Useful before formal registration
Creators can mark demos, stems, mixes, and previews at the moment they are shared, before publishing, distribution, or catalog registration is complete.
Composable identity
A wallet can connect to ENS, collectives, label accounts, onchain releases, or licensing workflows, so the same proof can plug into broader creator infrastructure.
Where SonoSig Fits
Demos and private previews
Encode tracks before sending them to collaborators, A&R, playlist curators, clients, or press. The proof helps show who originated the file and when it was signed.
Stems, loops, and sample packs
Mark individual assets so they keep a creator or rights-holder link after they are downloaded, renamed, imported into a DAW, or passed between teams.
Licensing and sync review
Attach a wallet-backed claim to review copies used in film, game, ad, and creator licensing workflows, where files often move outside one platform.
Marketplaces and collectives
Let buyers, collectors, and community members verify that a track was signed by the expected wallet before they trust a listing or claim.
AI and remix provenance
Mark source audio, generated variations, or approved remixes so downstream listeners can distinguish authorized work from lookalike files.
Dispute support
A SonoSig proof is not a copyright registration by itself, but it can support a timeline by pairing a signed wallet claim with a specific audio file.
