What problem does it solve? Setting up reliable blockchain node access and choosing the right RPC methods is time-consuming, especially when working across multiple chains like XRPL, Ethereum, and Base. This Skill provides ready-to-use endpoint configuration patterns, a complete XRPL RPC method reference, and guidance for real-time data streaming. ## Core Features & Use Cases - Endpoint Setup: Step-by-step configuration of QuickNode RPC URLs for scaffold-xrp (.env) and boundless (secrets.toml) across XRPL, Ethereum, Base, and testnets. - XRPL RPC Reference: Complete tables of account, ledger, transaction, NFT, DEX, and subscription methods with a working account_info fetch example. - Real-Time Data & AI Integration: Covers Streams, Webhooks, SQL Explorer, Admin API, llms.txt indexes, and the QuickNode MCP server for LLM workflows. - Use Case: You are building an XRPL app with scaffold-xrp and need to query account balances and stream ledger events. Use this Skill to configure your QuickNode endpoint and call account_info and subscribe methods correctly. ## Quick Start Set up a QuickNode RPC endpoint for my XRPL project and show me how to query an account's balance using the account_info method.
