Developer Actions

Use the delegated materials to act on behalf of the user.

Recommended: JavaScript SDK for React Native

While this SDK is still supported, we recommend using newer JavaScript SDK, which is optimized for React Native, but also comes with a host of other benefits.

These actions run on your server using the decrypted delegated share and per‑wallet API key.

Use the delegated wallet

Once you decrypt and store the delegated materials, you can perform allowed actions scoped to that wallet.

EVM

Use the EVM helper to act on behalf of the user. walletApiKey comes from decrypting data.encryptedWalletApiKey; keyShare comes from decrypting data.encryptedDelegatedShare.

const { createDelegatedEvmWalletClient, delegatedSignMessage } = import('@dynamic-labs-wallet/node-evm');

const client = createDelegatedEvmWalletClient({
  environmentId,
  apiKey
});

const signature = await delegatedSignMessage(client, {
  walletId,
  walletApiKey,
  keyShare,
  message,
});

SVM

Use the SVM helper to act on behalf of the user. walletApiKey comes from decrypting data.encryptedWalletApiKey; keyShare comes from decrypting data.encryptedDelegatedShare.

const { createDelegatedSvmWalletClient, delegatedSignMessage } = import('@dynamic-labs-wallet/node-svm');

const client = createDelegatedSvmWalletClient({
  environmentId,
  apiKey
});

const signature = await delegatedSignMessage(client, {
  walletId,
  walletApiKey,
  keyShare,
  message,
});
