SKALE Programmable Privacy

Monorepo for SKALE Programmable Privacy tooling — encrypted ERC-20 transfers with on-chain confidential computation.

Packages

Package	Version	Description
@skalenetwork/privacy-sdk		TypeScript SDK — core classes and actions
@skalenetwork/privacy-mcp		MCP server — AI agent integration via Model Context Protocol

How it works

SKALE stores token balances and transfer amounts encrypted on-chain. A Conditional Transaction (CTX) lets smart contracts decrypt data on demand — only when specific conditions are met — with the result delivered in a callback one block later.

Block N:    Your tx → submitCTX(encryptedArgs)
Block N+1:  Ephemeral wallet → onDecrypt(decryptedArgs) → balances updated

The SDK abstracts this two-block lifecycle. The MCP server exposes it as intent-based tools that AI agents can call directly.
