Skip the guesswork and put real-world inputs into your XDC apps with a workflow you can ship today. Start by selecting a ready-to-use reference feed from Plugin’s catalog—prices, FX, commodities, rates, weather, and more—then link the feed address in your consumer contract. Set practical guardrails: how fresh the data must be, the maximum allowed deviation before updates trigger, and the minimum number of responding sources needed. Fund the contract with the necessary gas and oracle fees, deploy on your preferred XDC network, and verify values on-chain using the provided interfaces. This gets you from idea to live data in minutes without building your own aggregation layer.
For finance builders, tighten risk controls directly in your smart contracts. Define a primary feed for each market you list and a fallback source in case the primary is stale or outside thresholds. Use medians over multiple providers to reduce outliers, add staleness checks before every trade or liquidation action, and enable circuit breakers that freeze sensitive functions when inputs drift outside your tolerance band. With clear parameters for update frequency and deviation, you can balance latency against cost and ensure lending health factors, DEX oracles, and collateral ratios always reference recent and verified information.
Need a custom signal that’s not in the catalog? Create a job that pulls from one or more authenticated APIs or enterprise systems. Normalize each source to a shared schema, apply filters to remove outliers, and specify how the network should combine results (median, mean, or weighted logic). Set update conditions by time or by change percentage, then test on an XDC test network before promoting to production. When you go live, the network posts signed results on-chain, and your contracts read a single, consistent value with a known update policy. This is ideal for supply-chain milestones, IoT telemetry, insurance parameters, or specialized industry indexes.
Operate with clarity. Use monitoring endpoints to track feed freshness, last update block, participating sources, and current aggregation status. Configure alerts for missed heartbeats, unusual variance, or budget thresholds so you can react before users notice. Keep costs in check by batching updates, tuning deviation triggers, and capping daily spend per feed. Lock critical admin functions behind multisig, set immutable addresses after audit, and maintain a pause switch for emergency conditions. When you need to scale, clone proven configurations across markets, rotate providers without downtime, and publish versioned feeds so integrators can upgrade on their own schedule.
