Chain delivers a high performance, secure, and cost efficient platform with everything builders and users need to thrive. ### EVM compatible development * Full EVM support so you can deploy or migrate Solidity smart contracts and dApps without changes * Works with Remix, Hardhat, Truffle, ethers.js, web3.js, and standard libraries to speed up builds and reviews ### Performance and cost efficiency * Delegated Proof of Stake for fast finality, strong security, and energy efficiency * Engineered for 20,000 plus transactions per second to support demanding consumer grade apps * Ultra low fees so frequent interactions and complex strategies remain economical ### Native GRX utility and governance * GRX is the native gas asset used to pay network fees * Staking for validators and delegators at **staking.grxchain.io** * Governance for proposals and votes at **proposal.grxchain.io** * Supply discipline through the tokenomics burn and rewards design * Exchange alignment: on **GroveX**, all marketing and new listing fees are payable in **GRX**, creating continuous structural demand ### Ecosystem growth and core products * Foundation for DeFi, NFTs, games, and consumer dApps with low latency and predictable fees * Native DEX **GRXswap** at **grxswap.io** as the primary liquidity hub for GRX Chain assets * GroveX pegged assets such as GAUD, GUSD, GETH, GBTC to enable deep stable pairs and seamless value flow into GRX Chain * Backed by GroveX for strategic guidance, brand reach, and user acquisition * Builder support including dApp funding initiatives, technical enablement, listings and co marketing, and liquidity support for qualified projects ### Reliability and service targets * Uptime targets: RPC and Explorer at 99.9 percent or higher monthly * Performance: median inclusion time under 2 seconds during normal load * Incident response: severity one acknowledgement within 30 minutes and a post incident report within 7 to 14 days ### Official infrastructure * RPC endpoints: `https://rpc.grxchain.io` for mainnet and `https://testnet.grxchain.io` for testnet * Explorer: `https://grxscan.io` and `https://testnet.grxscan.io` * Staking portal: `https://staking.grxchain.io` * Governance portal: `https://proposal.grxchain.io` * Bridge current official: `https://grovex.io` * DEX: `https://grxswap.io` ### Canonical assets quick reference * WGRX ERC20: `0x45C7287F897B3A79Cd3f6e4F14B4CE568f023bD5` with 18 decimals * USDT pegged: 0x173462F5eb7CA0D1ab6aaea846fEFe85A28029E2 * BTC pegged: `0x2F4632ABAd26A1FF9212a76597fb3c3d8539E275` * ETH pegged:

verification status, logs, and transaction lookups * Event indexing best practice: Multicall batching and `eth_getLogs` in two thousand to five thousand block windows ### Security posture * Delegated Proof of Stake with slashing for double signing and extended downtime * Recommended controls: multi sig for upgrades and treasury, timelocks of 24 to 72 hours, and least privilege roles * Independent audits required for canonical upgrades and verification on GRXscan is mandatory ### Compliance and regional notes * GroveX Pty Ltd in Australia operates the exchange and may require KYC and AML depending on jurisdiction * GRX Chain is owned and operated by **GRXCHAIN Inc.** in BVI * Builders are responsible for dApp specific compliance in their target markets ### Support and programs *

Versioning and deprecation * Semantic versioning for SDKs and canonical contracts * Minimum fourteen day notice for breaking changes unless a security fix * Deprecated addresses archived in Docs with successors and dates ### Testnet to mainnet readiness * Dry run deployments on testnet, audit remediation complete, and addresses verified on the testnet explorer * Multi sig and timelock wired before mainnet activation * Public changelog entry and known risks section at launch ### Analytics and insights * Prebuilt dashboards for transaction success, inclusion time, gas per function, holders, TVL, and volume on GRXswap * Alert templates for revert spikes, gas regressions, liquidity drops, and admin or role changes ### Wallet and integration coverage * One click Add Network snippets for MetaMask and OKX Wallet * Ledger and Trezor supported through those wallets and chain parameters are published * Token lists include WGRX and pegged assets verified on GRXscan > Always verify contract addresses and endpoints on **grxscan.io** and the Official Channels page before interacting.
