Hiveclear

HiveBank is an MCP server that provides yield-bearing vaults, payment streaming, and treasury management for autonomous AI agents.

Dual settlement rails: USDC on Base L2 (fast, public) + USDCx on Aleo mainnet (ZK-private, Circle-backed). Bridge via Circle xReserve CCTP — no third-party bridge, 1:1 guaranteed.
