DIA deploys price oracles that contracts query with a key such as BTC/USD to get an 8-decimal price and timestamp. Each oracle has a gas wallet that must hold native tokens to pay for updates, and DIA's grants program covers deployment and update costs for up to 1 year. Its chain guides list a Stacks mainnet oracle, a Stellar testnet oracle and demo push oracles on Base and Arbitrum mainnet. On the XRP Ledger, DIA runs a mainnet price oracle (BTC, ETH, XRP, RLUSD, USDC, USDT, EUROP) that apps read with the ledger_entry API.

Catch You fund the gas wallet for updates; Stellar oracle is testnet only and EVM ones are demos
