Supported Chains

EmbarkAI supports 6 blockchain networks across mainnet and testnet environments.

Chain Details

Lumia Prism (Mainnet)

Lumia Prism is the production mainnet. Use this for live applications handling real assets.

Lumia Beam (Testnet)

Lumia Beam is the primary testnet for development. It mirrors mainnet behavior and is the default chain in the SDK.

Ethereum Sepolia

BSC Testnet

Arbitrum Sepolia

Base Sepolia

Shared Infrastructure

All chains share the same EntryPoint v0.7 address (0x0000000071727De22E5E9d8BAf0edAc6f37da032) and Multicall3 address (0xcA11bde05977b3631167028862bE2a173976CA11).

The EmbarkAI bundler service handles UserOperation submission and gas estimation on every supported chain. Each chain has a dedicated bundler endpoint listed above.

Using Chain Configs in Code

The SDK provides built-in chain configurations:

import { getChainConfig, isChainSupported } from '@embarkai/core'
 
// Get full config for a chain
const config = getChainConfig(994873017)
console.log(config?.name)          // 'Lumia Prism Mainnet'
console.log(config?.rpcUrls)       // ['https://mainnet-rpc.lumia.org']
console.log(config?.bundlerUrl)    // 'https://api.lumiapassport.com/rundler-prism'
console.log(config?.factoryAddress)
 
// Check support
isChainSupported(994873017) // true
isChainSupported(1)         // false (Ethereum mainnet not yet supported)

For viem integration:

import { getViemChain } from '@embarkai/core'
 
const chain = getViemChain(994873017)
// Use with viem's createPublicClient, createWalletClient, etc.
