At Xythum Labs, we're solving the privacy trilemma balancing offchain and onchain privacy, DeFi composability, and compliance. users get fully shielded private asset management through threshold-encrypted UTXOs, (with Notes for internal balances and Memos for programmable transfers like atomic swaps), all while connecting to public DeFi via composable adaptors that verify proofs and execute callbacks atomically. We've got a decentralized solver network planned to handle private settlements with recursive ZK proofs, keeping things liquid and MEV-resistant. For compliance, weighted threshold encryption on the ciphertexts lets users decrypt their own notes solo, but requires a t-of-n quorum for any authorized access via onchain proposals.
For offchain privacy, we are implementing a Sphinx-style mixnet of relayers to hide IP metadata and sponsor fees privately, alongside PIR-based queries with OPRF for wallets (stateless) to detect memos without exposing viewing keys or patterns.
