SonoSig

SonoSig proves a technical provenance claim that a specific wallet signed a claim for a specific media fingerprint, and that the encoded file contains a valid proof. Combined with agentic trust signals from ENS, PacStac & Blockchain we're able to provide instant trust for agents, portable provenance, public discovery, and generate value for assets you steward. 0G is used for registration storage on the 0G Galileo Testnet.

SonoSig is built with Next, React, Tailwind, Firebase, RainbowKit/wagmi/viem, and a Node MCP server. The browser handles audio decoding, proof creation, waveform UI, wallet signing, and embedding. Server routes handle PacStac registration, ENS/RPC lookups, transaction receipt checks, admin config, and agent support chat. PacStac provides the discovery/indexing layer for signed media claims, ENS provides creator-controlled public pointers, x402 supports paid PacStac API reads on Base, and the MCP server lets agents verify files, register proofs, prepare ENS records, and run Agentic Scan. The hacky but useful part: the audio proof is portable inside the file, while ENS points to a wallet level collection so one text record can represent an entire catalog instead of one song.
