@yezhov.near [Posted on Developer DAO Board](https://near.social/#/devgovgigs.near/widget/Post?id=408) ## Idea: Private Transactions Productionisation on NEAR In Nov’22 ZeroPool launched a private transactions network on NEAR testnet https://twitter.com/ZeroPoolNetwork/status/1589892362922516480 . Private transactions, in addition to being an innovative technology, provide an added value to DeFi space. This proposal outlines a concrete way on how we can make them pervasive in the NEAR ecosystem, thus differentiating NEAR from other similar Layer-1s. Instead of launching a single private transactions dApp, we could create a contract standard extension to a fungible token standard https://nomicon.io/Standards/Tokens/FungibleToken/ , allowing all fungible tokens that implement this extension to act as a private transactions network for its token. Proof generation can happen inside near-api-js transparently to the user, without relying on the relayers or other kinds of services, besides the basic RPC providers. DeFi projects, including wallets, then would only need to support the extension of the smart contract standard, instead of integrating with a single private transaction network, which might be much more acceptable to them. The high-level roadmap - Discussion of the fungible token standard extension, as well as the accompanying near-api-js extension for proof generation. Involved parties: - ZeroPool and NEAR ZK Community Group (Anton Yezhov and ZeroPool team already briefly discussed this idea and want to collect the feedback across Near community); - Contract Standards Work Group: - to approve fungible token extension; - to evaluate SNARKs gasless verification (gas refund incase of successful verification) and tokenomics for it; - Tools Work Group – to approve near-api-js extension; - Wallet Work Group – to make sure the developed extension are acceptable by the wallets; - Eugene Kuzyakov from Proximity – to make sure the new APIs are acceptable by the NEAR DeFi ecosystem; - Implementation of the necessary components that were agreed on by the above parties; - Adding support to the first Wallet, e.g. https://herewallet.app/ - Working with Proximity, and potentially NEAR Foundation BD and/or Accelerator on adding support for NEAR DeFi projects. We are glad to hear community opinions and feedback, as well as open to discuss the ideas and privacy features that can be added to this initiative!
