Stablecoins made it easier to move money, but harder to keep those payments private. They work well for simple transfers, but using them for payroll or regular spending can expose information most people don't want public. @Arcium keeps balances and transaction details private while settlement remains public and verifiable. Nodes process encrypted data together, allowing payments to be verified without any one node seeing the full details. C-SPL brings Arcium’s private compute into Solana’s existing token model, giving developers confidential balances and programmable transfers without forcing them to build the privacy layer from scratch. That means payroll can run on stablecoin rails without exposing compensation structures, non-custodial cards can work without publishing spending amounts, and remittances can recur without mapping family networks. If stablecoins want to become everyday money, privacy has to be built into the way payments execute.(Delphi Digital)
