For production applications, consider running your own node or using dedicated RPC providers. **Rate Limits:** * 10 requests per second per IP * 1000 requests per hour per IP * Some methods may have additional restrictions ### RPC Methods Supported JSON-RPC methods: * Standard Ethereum JSON-RPC API * `eth_*` methods (accounts, transactions, blocks, state) * `net_*` methods (network information) * `web3_*` methods (utilities) * `debug_*` methods (debugging - limited on public nodes) * `posv_*` methods (PoSV-specific queries) ## Bootnodes Bootnodes help new nodes discover peers on the network. ### Mainnet Bootnodes From `params/bootnodes.go`: ```go theme={null} VicMainnetBootnodes = []string{ "enode://98b06c30c631ab869c25b4836684b3de632ec7db60db34920095f8039cd49076913a64565dc4d8a06569bd84afa9553b95590ba3dd86263e3b9b5657463693a7@162.19.43.250:30301", "enode://4c075010c7c1199240aea58a4e570b13af374a4aa2ed0219360c6017da34ca644706426ab2c75f1da00552ef4a40245ba043854d20e7c1873306023b6790bf03@15.235.228.11:30301", "enode://477afcdf9581d0f38f00b2d0376bb536a3c71b13fcfa3d6039efb19c57a69e389b819efeb516609fe3eb3c90a8ffe620e62abaf481de6b07b873cad543a635fb@162.19.103.252:30301", "enode://6a03f00972d02bc1f004fd05adf9384fb05a629e69ae894eebe1b55fe667a2313b595a180418f505948f99e5c66661229f8ea1d5c12aadb16433cae3122d1d8a@3.1.61.17:30301", "enode://f799bf1da9f8b25891054913d876b1dcc301284fd001078239bcb5fb408078ac89741b8039f9adb0dfbfe72dca0b753e48099de3a059c3e23dc2402434ff8fd6@13.229.196.181:30301", "enode://d3a79693bf18fd5136a4b1809193e28f94400b00a65a7f21c918876d986212c8031834b332f39fb8a814fb5e90f0e413fead6953d1aa23a839bba1224e285ed6@122.248.245.143:30301", } ``` ### Testnet Bootnodes ```go theme={null} VicTestnetBootnodes = []string{ "enode://77c303c0d7cd03cb0fcfee0b7fc1b162d2fcaf667dc23b416e631196c8d7bed9b937944372b4673bc3d8dcede4b37bf8e7e8855bbda76c96bba3fb573a10f1ad@162.19.43.250:30304", "enode://b9b5f61ab47f3681e75240d8b86d05ab451cd47f206d1d3cb69a87c71491236cec10b8a7740ec88616199d6a76d309f41a647e2802a63a8e449773ee3a920ba4@15.235.228.11:30304", "enode://0f41c53da72e07e3514efd7ce9e3f758acc2066d8ae66955e540620f7108fff91f8ebdc734b89dca14db2a70cdaf8c957579ec94e3dfdfe91b2923272f1cc099@13.214.64.64:30601", } ``` ## Wallet Configuration ### MetaMask Setup #### Mainnet 1.
