Integrating chains

The React SDK enabled chains by passing a walletConnectors array to the provider. In the JavaScript SDK you enable each chain by calling its add<Chain>Extension() once when you set up the client.

The React SDK turned chains on by passing connector packages into DynamicContextProvider’s walletConnectors array (EthereumWalletConnectors, SolanaWalletConnectors, and so on). The JavaScript SDK replaces that array with extensions: for each chain you install its package and call add<Chain>Extension(client) once, right after you create the client and before you use it. Each extension registers that chain’s wallet providers and network support.

Enabling a chain

Enabling a chain is the same call whether or not you use React — add each extension to the client right after you create it:

import { createDynamicClient } from '@dynamic-labs-sdk/client';
import { addEvmExtension } from '@dynamic-labs-sdk/evm';
import { addSolanaExtension } from '@dynamic-labs-sdk/solana';

const dynamicClient = createDynamicClient({
  environmentId: 'YOUR_ENVIRONMENT_ID',
});

// Enable each chain your app supports:
addEvmExtension(dynamicClient);
addSolanaExtension(dynamicClient);

In React, pass the configured dynamicClient to DynamicProvider (see Basic setup).

What maps to what

React SDK (walletConnectors)	JavaScript SDK extension	Package
EthereumWalletConnectors	addEvmExtension()	@dynamic-labs-sdk/evm
SolanaWalletConnectors	addSolanaExtension()	@dynamic-labs-sdk/solana
BitcoinWalletConnectors	addBitcoinExtension()	@dynamic-labs-sdk/bitcoin
CosmosWalletConnectors	addCosmosExtension()	@dynamic-labs-sdk/cosmos
StarknetWalletConnectors	addStarknetExtension()	@dynamic-labs-sdk/starknet
AptosWalletConnectors	addAptosExtension()	@dynamic-labs-sdk/aptos
Sui connectors	addSuiExtension()	@dynamic-labs-sdk/sui
TON connectors	addTonExtension()	@dynamic-labs-sdk/ton
Tron connectors	addTronExtension()	@dynamic-labs-sdk/tron
Stellar connectors	addStellarExtension()	@dynamic-labs-sdk/stellar

addEvmExtension() bundles the EIP-6963 browser-wallet discovery and the embedded (WaaS) EVM provider, so a single call covers both external and embedded EVM wallets. On Solana, add addPhantomRedirectSolanaExtension() alongside addSolanaExtension() when you need the Phantom mobile redirect flow.

Per-chain reference

Each chain’s own setup, supported wallets, and network configuration are documented in the JavaScript reference — start with Adding extensions, then the page for your chain:

• EVM
• Solana · Phantom redirect
• Bitcoin
• Sui
• Aptos
• Starknet
• Stellar
• TON
• Tron
• Other chains
