What problem does it solve? Developers integrating the Flare Data Connector (FDC) must understand attestation types, verifier and DA Layer APIs, Merkle proof retrieval, and on-chain verification, which are spread across many docs and starter repos. This Skill consolidates that protocol knowledge into one guidance reference. ## Core Features & Use Cases - Attestation Type Reference: Covers EVMTransaction, Web2Json, Payment, AddressValidity, XRPPayment, XRPPaymentNonexistence, and FAssets-oriented types with request/response field details. - End-to-End Workflow Guidance: Documents the prepare → submit → wait for finalization → fetch proof → verify in contract flow, including FdcHub, Relay, and IFdcVerification usage. - Starter Repo Pointers: Maps to canonical Hardhat and Foundry examples such as proof-of-reserves and weather insurance dApps. - Use Case: When writing a Solidity contract that consumes a Web2Json proof, use this Skill to get the correct verification pattern, ABI decoding approach, and security guidance for handling external attestation data. ## Quick Start Ask how to verify an EVMTransaction proof in a Flare smart contract and follow the documented prepare, submit, and verify workflow.
