Building a Pre-Trade Oracle Safety Check for DeFi Agents

An agent constructing a valid transaction may still make a poor decision if the price data used is stale or inconsistent. This holds particularly true for lending, where even a minor oracle discrepancy can reduce a position's liquidation buffer before the agent submits a borrow. To address this issue, the developer is building a tool called Insight, designed to provide a practical checkpoint before a swap, borrow, lend, repay, or liquidation occurs.

Insight's Oracle Safety Check compares prices across multiple providers, verifies their freshness, and ensures provider independence. It also monitors stablecoin depeg events and returns a machine-readable verdict - PASS, CAUTION, DANGER, or BLOCK. For lending specifically, the check evaluates how much of the protocol's liquidation buffer is consumed by the observed price dispersion.

The primary goal of Insight is to give DeFi applications a decision-making tool. For instance, an agent preparing a new borrow can adjust its position size, wait for prices to converge, or halt the borrow entirely when the check returns a serious warning. The TypeScript Guard SDK can use the Insight result to gate a transaction submission. Additionally, Oracle Watch gives a separate signal for monitoring an active strategy between trades.

Insight incorporates signed EIP-712 attestations, allowing developers to independently verify receipt data. However, Insight should be seen as an advisory and risk-evidence layer rather than a live price feed. The cadence of data collection is defined, so it should not be mistaken for a real-time price feed.

When building DeFi agents, developers should place the final gate before a transaction is signed. For more information, visit the official website at https://www.oracleinsight.xyz/ or check out the source code on GitHub at https://github.com/imokokok/Insight.git.
