GoldRush offers the most comprehensive MegaETH Data API suite for developers, analysts, and enterprises. Whether you're building a DeFi dashboard, a wallet, a trading bot, an AI agent or a compliance platform, our MegaETH Data APIs provide fast, accurate, and developer-friendly access to the essential onchain data you need. ### Supported APIs Access structured historical blockchain data across 100+ chains using REST APIs. Get token balances, transaction histories, decoded event logs, NFT assets, token holders and more.

Use cases: Wallets, portfolio trackers, crypto accounting & tax tools, and DeFi dashboards. Low-latency EVM JSON-RPC with global failover and archive depth. Point your existing tooling at the GoldRush endpoint — no code changes required.

Use cases: dApps, wallets, indexers, bots, and trading infrastructure. ## Mainnet | Property | Value | | -------------------- | -------------------------------------------------------- | | **Chain Name** | `megaeth-mainnet` | | **Chain ID** | `4326` | | **Network Type** | Frontier Chain | | **Support Level** | frontier | | **Block Explorer** | [MEGA Mainnet Explorer](https://megaeth.blockscout.com/) | | **Official Website** | [MegaETH Website](https://www.megaeth.com/) | | **Native Gas Token** | ETH | ## API Usage To use this blockchain network in GoldRush API calls, use: #### Chain Name * `megaeth-mainnet` (mainnet) #### Example API Calls ```bash Chain Name (Mainnet) theme={null} curl -X GET "https://api.covalenthq.com/v1/megaeth-mainnet/address/0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045/balances_v2/?key=" ``` #### SDK Usage ```typescript TypeScript SDK (Mainnet) theme={null} import { GoldRushClient } from "@covalenthq/client-sdk"; const client = new GoldRushClient(""); const resp = await client.BalanceService.getTokenBalancesForWalletAddress({ chainName: "megaeth-mainnet", walletAddress: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045" }); ``` ## Foundational API Support This chain supports **22** GoldRush Foundational APIs: #### Wallet API * **[Get token balances for address on MegaETH](/docs/api-reference/foundational-api/balances/get-token-balances-for-address/)** * **[Get native token balance for address on MegaETH](/docs/api-reference/foundational-api/balances/get-native-token-balance/)** * **[Get historical portfolio value over time on MegaETH](/docs/api-reference/foundational-api/balances/get-historical-portfolio-value-over-time/)** * **[Get ERC20 token transfers for address on MegaETH](/docs/api-reference/foundational-api/balances/get-erc20-token-transfers-for-address/)** #### Pricing API * **[Get historical token prices on MegaETH](/docs/api-reference/foundational-api/utility/get-historical-token-prices/)** #### Security API * **[Get token approvals for address on MegaETH](/docs/api-reference/foundational-api/security/get-token-approvals-for-address/)** #### Transactions API * **[Get a transaction on MegaETH](/docs/api-reference/foundational-api/transactions/get-a-transaction/)** * **[Get transaction summary for address on MegaETH](/docs/api-reference/foundational-api/transactions/get-transaction-summary-for-address/)** * **[Get earliest transactions for address (v3) on MegaETH](/docs/api-reference/foundational-api/transactions/get-earliest-transactions-for-address-v3/)** * **[Get recent transactions for address (v3) on MegaETH](/docs/api-reference/foundational-api/transactions/get-recent-transactions-for-address-v3/)** * **[Get paginated transactions for address (v3) on MegaETH](/docs/api-reference/foundational-api/transactions/get-paginated-transactions-for-address-v3/)** * **[Get bulk time bucket transactions for address (v3) on MegaETH](/docs/api-reference/foundational-api/transactions/get-time-bucket-transactions-for-address-v3/)** * **[Get all transactions in a block (v3) on MegaETH](/docs/api-reference/foundational-api/transactions/get-all-transactions-in-a-block/)** * **[Get all transactions in a block by page (v3) on MegaETH](/docs/api-reference/foundational-api/transactions/get-all-transactions-in-a-block-by-page/)** #### Block Explorer API * **[Get a block on MegaETH](/docs/api-reference/foundational-api/utility/get-a-block/)** * **[Get all chain statuses on MegaETH](/docs/api-reference/foundational-api/utility/get-all-chain-statuses/)** * **[Get all chains on MegaETH](/docs/api-reference/foundational-api/utility/get-all-chains/)** * **[Get block heights on MegaETH](/docs/api-reference/foundational-api/utility/get-block-heights/)** * **[Get gas prices on MegaETH](/docs/api-reference/foundational-api/utility/get-gas-prices/)** * **[Get log events by contract address on MegaETH](/docs/api-reference/foundational-api/utility/get-log-events-by-contract-address/)** * **[Get log events by topic hash(es) on MegaETH](/docs/api-reference/foundational-api/utility/get-log-events-by-topic-hash/)** * **[Get logs on MegaETH](/docs/api-reference/foundational-api/utility/get-logs/)** ## JSON-RPC MegaETH is available on the GoldRush JSON-RPC service.
