Private Market is a permissionless p2p marketplace that enables any user to bid/ask private keys, signatures and groth16 proofs. We present here our zero-knowledge circuits and contracts used for privately exchanging cryptographic objects on Ethereum. First, we outline how property, encryption and commitment proofs work in the context of a p2p market. Then, we detail setups of increasing complexity for selling ECDSA keypairs, EdDSA Signatures and groth16 proofs in a trustless and privacy-preserving manner. While selling private keys of ethereum addresses and EdDSA signatures is relatively straightfoward, we have had to leverage recursivity to enable anonymous trades of groth16 proofs. We conclude by describing a setup where users can trustlessly sell execution of transactions themselves on Ethereum, laying out a potential construction of stealth transactions. Interestingly, this setup could be generalized to any kind of contract interactions - aka stealth interactions. Our motivation i
