gravity-skills

Reference for building smart contracts on and bridging to Gravity L1 (EVM-compatible Layer 1, chain ID 127001, native token G). Use when someone asks how to connect to Gravity (chain ID / RPC / explorer), bridge the G token from Ethereum (via cast, a wallet, or a contract), read the native on-chain oracle or write an oracle callback, use safe on-chain randomness (block.prevrandao), find a system or bridge contract address, or which canonical EVM preinstalls (Multicall3, Permit2, CreateX, ERC-4337, Wrapped-G) exist. Covers Gravity Mainnet (127001) and Longevity Testnet (7771625); distinct from the legacy Alpha Mainnet L2 (Arbitrum Nitro, chain 1625).
