Integritee AG is asking for 87,377 USD or 11,655 DOT from the treasury.
They have implemented a sidechain called Incognitee that can transfer a relaychain native token privately by shielding it to L2 and eventually unshielding it back to the relay chain without linkability.
They have demonstrated the transfer of DOT from a local Asset Hub to Incognitee and back in a demo video.
They are planning to launch a public test campaign and bug bounty on their Rococo testnet and support for Asset Hub and its fungible assets, i.e. USDC/USDT and ANY substrate based chain and its assets.
They had previously outlined their vision in a blog and had attempted to get treasury funding through Referendum 17, which was deemed too early for retro-active by commenters.
