Foundereum
Foundereum: A business account and metered toolbelt for AI agents, settled on Hedera.
Demo
About
Give an AI agent (Claude Code, any MCP client or your AI Pipeline) a Privy secured wallet, a spending policy, and an x402 API key. Every tool it uses, swapping tokens, transferring funds, or pulling live on-chain data from The Graph, is paid for automatically with a sub-cent HTS payment via Blocky402, inside limits your team sets and can audit on HCS. No subscriptions, no shared API keys, no unbounded agent access to your treasury.
How it's made
Foundereum is built in Go (API, Gateway, MCP server, Asynq worker) and React + TypeScript, backed by PostgreSQL (double-entry ledger) and Redis (rate limits, nonces). AI agents connect via Model Context Protocol (MCP). Every tool call is metered through HTTP 402: the gateway issues a cryptographic challenge, the agent’s wallet signs the payment, and tools execute only upon verified on-chain settlement. Partner Tech: • Hedera: Sub-cent HTS USDC micropayments and public auditability. Every settled call is committed to a Hedera Consensus Service (HCS) topic (0.0.10442234) verifiable on HashScan. • Privy: Provisions split Treasury and Agent server wallets in TEE enclaves. Spending limits and allowlists are enforced at the hardware level (default_action: DENY), with WebCrypto multi-sig quorums for withdrawals • The Graph: Powers our agent data tools via Messari standardized subgraphs for live, cross-chain DEX pool intelligence. Notable Hack: A zero-key automated x402 loop: the LLM never touches private keys or handles payment math. The gateway determines pricing from arguments, requests a TEE signature, settles atomically via Redis GETDEL (preventing replays), and returns verified data transparently.
