What are the public RPC endpoints for Sei EVM?

Sei Network provides several public RPC endpoints for both mainnet and testnet:

Mainnet RPC Endpoints:

Primary: https://evm-rpc.sei.io
Alternative: https://sei-mainnet-rpc.publicnode.com

Testnet RPC Endpoints:

Primary: https://evm-rpc.testnet.sei.io
Alternative: https://sei-testnet-rpc.publicnode.com

For production applications, consider:

1. Using a dedicated RPC provider for better reliability
2. Implementing failover between multiple endpoints
3. Running your own Sei node for critical applications

Example of RPC failover implementation:

// RPC failover implementation
async function getReliableProvider() {
  const rpcUrls = [
    "https://evm-rpc.sei.io",
    "https://sei-mainnet-rpc.publicnode.com"
  ];

  for (const url of rpcUrls) {
    try {
      const provider = new ethers.providers.JsonRpcProvider(url);
      await provider.getBlockNumber(); // Test connection
      console.log(`Connected to ${url}`);
      return provider;
    } catch (error) {
      console.warn(`Failed to connect to ${url}: ${error.message}`);
    }
  }

  throw new Error("All RPC endpoints failed");
}
