JS SDK v1: Sunsetting Public RPC URLs

On March 4, 2024, we will retire specific public RPC URLs used in conjunction with WalletConnect within the Moralis JavaScript SDK version 1 (v1). This update is crucial for users utilizing WalletConnect in the frontend with the default RPC URLs provided by Moralis. The affected URLs are formatted as follows: https://speedy-nodes-nyc.moralis.io/WalletConnect/eth/mainnet

Who Is Affected?​

  • Users of the Moralis JS SDK v1 who utilize WalletConnect without a custom RPC URL.

Who Is Not Affected?​

  • Users who have already migrated to the latest version of our JS SDK.
  • Users who do not use WalletConnect in v1.

Required Action​

To ensure your applications continue to operate seamlessly, affected users must transition to a custom RPC URL. This adjustment involves updating the rpcMap parameter within the Moralis.authenticate method to include your chosen RPC provider’s URL.

Summary and Migration Example​

To migrate from the deprecated speedy nodes, you’ll need to select an alternative RPC provider and specify its URL in the rpcMap parameter during authentication with Moralis.

Example Migration Step:

Moralis.authenticate({
  provider: "walletconnect",
  projectId: "<PROJECT_ID>",
  chainId: 1,
  rpcMap: {
    1: "<YOUR_CUSTOM_RPC_URL>",
  },
});
