Stellar and Nethermind introduce SPP for sensitive payment flows, using privacy pools to hide transaction counterparties while preserving public blockchain rails

Stellar Private Payments (SPP) is now live on testnet as a preview, built on a privacy pool implementation developed by Nethermind. Users deposit an asset into a shared pool contract, where the deposit becomes a commitment in a Merkle tree proving value exists without revealing ownership; funds can then be transacted and withdrawn without publicly linking payer to payee. More deposits enlarge the privacy set, making transactions harder to attribute. The preview includes configurable compliance tools: Association Set Providers, Global View Keys, Selective Disclosure via user view keys, and an embedded testnet deployment. A walkthrough with Nethermind's Antonio Larriba and Alessandro Voto is scheduled for Aug 28 at 4pm UTC.
