    {
      "id": "what-is-ugf",
      "question": "What is Universal Gas Framework?",
      "answer": "Universal Gas Framework is a cross-chain payment and execution coordination protocol. It enables Remote Transactions where source-chain value becomes destination-chain action."
    },
    {
      "id": "what-are-remote-transactions",
      "question": "What are Remote Transactions?",
      "answer": "Remote Transactions means value can stay on the source chain while the desired action completes on the destination chain. UGF routes the action path, not the user's liquidity."
    },
    {
      "id": "tagline",
      "question": "What is UGF's tagline?",
      "answer": "Route Actions, Not Liquidity."
    },
    {
      "id": "who-is-ugf-for",
      "question": "Who is UGF for?",
      "answer": "UGF is for users, wallets, Web3 apps, AI agents, developers, wallet teams, infrastructure partners, execution-layer researchers, and ecosystem operators."
    },
    {
      "id": "main-flow",
      "question": "How does UGF work at a high level?",
      "answer": "The common flow is authenticate signer, request a quote, route payment through x402 or vault, complete execution on the destination chain, and track status through API, registry, polling, UGF Scan, or indexed status surfaces where available."
    },
    {
      "id": "payment-chain-vs-destination-chain",
      "question": "Can payment chain and destination chain be different?",
      "answer": "Yes. UGF is designed so payment chain and destination chain can be different. Docs show an example where a user pays on Base and execution lands on BNB Chain."
    },
    {
      "id": "does-ugf-require-smart-wallets",
      "question": "Does UGF require smart wallets?",
      "answer": "No. The whitepaper describes UGF as EOA-native and explicitly not dependent on smart wallets."
    },
    {
      "id": "does-ugf-require-paymasters",
      "question": "Does UGF require paymasters, bundlers, or ERC-4337?",
      "answer": "No. UGF's site highlights no paymasters, no bundlers, and no ERC-4337 as contrast points."
    },
    {
      "id": "payment-methods",
      "question": "What payment methods does UGF document?",
      "answer": "UGF documents x402 as an authorization-first settlement path and vault as a payment-transaction-first settlement path. Both are bound back to the quoted job digest."
    },
    {
      "id": "x402",
      "question": "What is x402 in UGF?",
      "answer": "x402 is a payment path where the user authorizes token movement from their wallet. For supported routes, UGF may use ERC-3009 / TransferWithAuthorization-style semantics."
    },
    {
      "id": "vault",
      "question": "What is vault mode?",
      "answer": "Vault mode is a quote-based payment route where the payer settles on-chain first. UGF verifies the on-chain payment against the quote before continuing execution."
    },
    {
      "id": "supported-chains",
      "question": "Which chains are mentioned as supported?",
      "answer": "Current product materials describe Ethereum, Base, Optimism, Polygon, Avalanche, BNB Chain, Arbitrum, opBNB, Solana, Sui, TRON, and TON."
    },
    {
      "id": "supported-assets",
      "question": "Which payment assets are mentioned?",
      "answer": "The site and docs mention USDC, EURC, $U, ETH, MATIC, AVAX, BNB, STON in TON context, and TYI_MOCK_USD for Base Sepolia testnet faucet flows."
    },
    {
      "id": "route-availability",
      "question": "Are all tokens available on all routes?",
      "answer": "No. Payment options are quote-dependent. Apps should use the quote response and registry as source of truth for valid payment options."
    },
    {
      "id": "sdk-package",
      "question": "What is the main SDK package?",
      "answer": "The main SDK package documented by the site is @tychilabs/ugf-sdk."
    },
    {
      "id": "gateway-url",
      "question": "What is the default gateway URL?",
      "answer": "The documented default gateway URL is https://gateway.universalgasframework.com."
    },
    {
      "id": "public-endpoints",
      "question": "What public utility endpoints are documented?",
      "answer": "The API reference documents GET https://gateway.universalgasframework.com/health and GET https://gateway.universalgasframework.com/tokens/registry."
    },
    {
      "id": "is-ugf-trustless",
      "question": "Is UGF a trustless bridge?",
      "answer": "No. The whitepaper explicitly says UGF is not a trustless bridge paper. It is a protocol coordination paper with explicit trust boundaries."
    },
    {
      "id": "testnet-faucet",
      "question": "What is the UGF Base Sepolia faucet?",
      "answer": "The faucet lets developers lock Base Sepolia ETH, receive TYI_MOCK_USD, and test x402 Payment Routing without production funds."
    },
    {
      "id": "tyi-mock-usd",
      "question": "Is TYI_MOCK_USD real money?",
      "answer": "No. TYI_MOCK_USD is a Base Sepolia ERC-20 mock USD payment coin for development and testnet flows only."
