ACCRUE for AI Agents

ACCRUE is a non-custodial, AI-native stablecoin yield optimization platform. ACCRUE never holds an agent’s keys, funds, or signing authority — every figure is a public contract read with a timestamp, and every action is a transaction the agent’s own wallet signs. ACCRUE has deployed a set of fully operational tools already accessible to autonomous agents, with the remaining functionality scheduled for release in the near term: the Stablecoin Yield Index (SYX) is live today as a real, queryable TVL-weighted USDC benchmark, and the discovery and data layer — the MCP server, REST API, OpenAPI spec, agent.json, and llms.txt — is live today and answers real requests with no API key and no authentication. Yield strategies, including standalone vaults and model portfolios, are not yet publicly launched: deposits are gated behind an independent smart-contract audit and currently restricted to allowlisted addresses, so an agent can read everything today and cannot yet deposit. ACCRUE offers twelve standalone ERC-4626 vaults across Aave v3, Compound v3, and curated Morpho v2 vaults from Steakhouse Financial and Gauntlet; three fixed-weight, risk-adjusted model portfolios — Foundation, Core, and Growth — built on a published, immutable construction rule; custom portfolios with agent-chosen weights; and Stable Rate, which lets a holder lock a known yield for a known period while ACCRUE absorbs the downside if the underlying market earns less. Every vault is classified into one of three published risk tiers under a weighted methodology, with real-time and historical TVL, yield, and utilization available per market. For curated Morpho vaults, ACCRUE provides a real-time breakdown of all underlying markets each vault routes to — the detail most comparable venues do not surface. An agent can pay network fees in USDC instead of ETH two ways: live today via Circle’s paymaster (usdc_path in the MCP prepare_transaction tool, enabled on both Ethereum and Base, no ETH needed after a one-time EIP-7702 authorization that keeps the agent’s own address), or via ACCRUE’s own signed-intent gas router for ordinary EOA wallets (built and tested, not yet deployed) — either way the agent always pays its own fee; ACCRUE pays or subsidizes nothing.
