Manta zkNFTs and zkSBTs: private minting with zkAddress
Thread627 words
Explains soul-bound tokens and how Manta extends MantaPay to private NFTs and SBTs via its NFT Private Offering launchpad, reusable zkAddresses and proof keys for walletless identity checks. Chain-agnostic zkSBTs keep credentials private on Manta.
Key claims
zkSBTs are bound to a single zkAddress but one zkAddress can hold multiple
zkSBTs can be launched on other chains while privacy credentials stay on Manta
Proof keys verify identity without wallet disclosure
0/ has been a while since I last covered @MantaNetwork
but since @MantaNetwork has recently announced a true #zk-powered REVOLUTION of the #NFT space, it's time once again 👀
a 🧵 on #zkNFTs & #zkSBTs (0/19) 👇
1/ originally, the #MantaPay protocol only supported fungible assets. However, to truly bring #privacy to #web3 at scale, @MantaNetwork needs to support a broader array of asset classes. More specifically, non-fungible tokens (NFTs & soul-bound tokens (SBTs)

4/ but back to #NFTs & #SBTs
most of you are probably familiar with #NFTs. But WTF are #SBTs?
soul-bound tokens are digital identity tokens representing a person or entity’s characteristics, features, traits or achievements and aims to take #NFT applications to the next level
5/ unlike #NFTs, #SBTs cannot be transferred or traded between different owners (hence the name)
6/ in January 2022, @VitalikButerin posted an article about soul-bound tokens (see link below)
vitalik.ca/general/2022/01/26/soulbound.html
in his blog post, Vitalik Buterin discusses the challenges of adding privacy to soulbound items, which cannot be moved to a new account or smart contract...
7/ ...like transferable #NFTs can. He notes that as proof of humanity becomes more widely adopted, #privacy becomes increasingly important, as in the absence of privacy, all on-chain activity could be directly linked to a person’s identity
8/ so, how is $MANTA going to address this?
last week, @MantaNetwork announced the integration of SBTs and NFTs into #MantaPay, which is based on cutting-edge #zk technology. These assets can be minted through its upcoming platform that enables #NFT Private Offerings (NPOs)
9/ @MantaNetwork's NPO platform is set to revolutionize how users generate and mint zkNFTs & zkSBTs. It is a unique product that allows any projects or users on $MANTA to launch #zkNFTs or #zkSBTs privately without any technical or cryptographic experience
10/ the decentralized #zkNFT & #zkSBT launchpad that combines zero knowledge technology with NFTs, enabling private minting & verification
11/ with NPO, users can easily mint NFTs & SBTs while maintaining the privacy of their crypto assets. By leveraging @MantaNetwork’s zkAddress tooling, NPO enables users to mint NFT & SBT assets on their zkAddress while using the public addresses’ tokens to pay for the minting fee
12/ the #zkAddress is a core piece of @MantaNetwork's tech stack. The zkAddress is a reusable, independent & auditable address to host private assets on $MANTA
13/ while a #zkSBT is not transferrable and hence bound to a single #zkAddress, one zkAddress can hold multiple zkSBTs
14/ so, to recap, #zkSBTs (zero knowledge soul-bond tokens) are an enhanced form of soul-bond token that use #zk-proofs to provide security and privacy features that go far beyond traditional #SBTs
15/ moreover, #zkSBTs are easy to mint and use for verification purposes, offering the same user experience but with added privacy
16/ and @MantaNetwork's zkSBTs are even chain-agnostic, meaning users can launch the tokens on other chains including @ethereum, @0xPolygon & more, while the privacy credentials are maintained on $MANTA, which can be verified through in a privacy-preserving way through proof keys
17/ the "proof key" is a protocol developed by @MantaNetwork that allows users to verify their identity on-chain without the need for wallet disclosures
18/ the proof key makes it easier for apps to check the identity/ownership of a #zkSBT as users simply need to show the zkSBT has been minted to a #zkAddress they have ownership over to prove their identity & ownership
19/ @MantaNetwork’s NPO platform & #zk-enabled privacy for NFTs & SBTs are definitely a game-changer in the #NFT and especially #SBT space, bringing privacy to non-fungible assets leveraging the #MantaPay zk circuit
