AlphaYields is the yield layer of DeFi — diversified onchain yield through a single liquid asset. We issue ayTokens: one liquid, yield-bearing token per asset, but where most yield tokens earn from a single source, an ayToken holds a diversified portfolio of verified DeFi strategies — for any asset you hold (ETH, BTC, FLOW, USD). Deposit once and hold the ayToken; underneath, we discover, verify, allocate, and rebalance across strategies, with every figure computed from chain and verifiable at any block.
CollateralRails is a trust and protection layer for AI agent payments. As AI agents begin making autonomous purchases, existing payment protocols can authorize and execute transactions, but they do not fully answer one critical question: can the seller be trusted to deliver? For high-value commerce, escrow, arbitration, and human dispute resolution may work. But for small agentic payments, such as API calls, tool usage, data access, or micro-services, those models are too slow and too expensive. A $0.03 transaction cannot support a manual dispute process. CollateralRails solves this by shifting protection from buyer-side escrow to seller-side accountability. Sellers register on-chain and post a performance bond. AI agents can then pay sellers directly, but only if they satisfy predefined policy rules. After payment, the seller must provide a valid delivery receipt. A watcher verifies the receipt and updates the seller’s reputation. If delivery succeeds, the seller’s reputation improves. If delivery fails, or no valid receipt is provided, the buyer is automatically refunded from the seller’s bond. The seller is slashed, reputation is reduced, and repeated failures can lead to delisting. Buyer funds are never escrowed. Payments remain fast and direct. Trust comes from bonded sellers, automated verification, and programmable enforcement. CollateralRails makes agentic commerce safer by giving AI agents a simple trust rule: Pay only sellers who are bonded, verified, and within policy limits.
