Create chain wallet

​

Dashboard: Networks

1. Open your app in the Abstraxn Dashboard.
2. Go to Wallets → select your wallet service → Networks.
3. Choose EVM only, Solana only, or Both.

• New apps default to EVM only.
• Changing the setting affects new signups and new server wallets only.
• Existing users keep their current addresses. Turning a chain on does not auto-create missing accounts; turning a chain off does not delete keys.
• The SDK modal hides chains your app setting disables (you can still force Solana in demos with chains.enableSolana: true).

​

Enable Solana later (example)

1. In the dashboard, change Networks from EVM only to Both (or Solana only if that matches your product).
2. In your app, show a control when the user is missing a Solana address and the app allows Solana:

import { useAbstraxnWallet, useWhoami } from "@abstraxn/signer-react";

export function EnableSolanaButton() {
  const { createChainWallet, walletChains, isConnected } = useAbstraxnWallet();
  const { whoami, refreshWhoami } = useWhoami();

  const solanaAllowed =
    walletChains === "solana" || walletChains === "both";
  const needsSolana =
    isConnected &&
    solanaAllowed &&
    !whoami?.solanaAddress &&
    !!createChainWallet;

  if (!needsSolana) return null;

  const handleEnable = async () => {
    try {
      const result = await createChainWallet("solana");
      console.log("Solana address:", result.address, result.alreadyExists);
      await refreshWhoami();
    } catch (error) {
      console.error("createChainWallet failed:", error);
    }
  };

  return (
    <button onClick={() => void handleEnable()}>Enable Solana wallet</button>
  );
}

​

Core SDK

import { AbstraxnWallet } from "@abstraxn/signer-core";

const wallet = new AbstraxnWallet({ apiKey: "your-api-key" });
await wallet.connect();

const { address, alreadyExists } = await wallet.createChainWallet("solana");

​

What happens

1. Client calls POST /wallet/create-chain-account/prepare with { blockchain: "evm" | "solana" }.
2. If the account already exists, the API returns that address (idempotent).
3. Otherwise the client stamps a Turnkey create-wallet-accounts activity and submits POST /wallet/create-chain-account/submit-stamped.
4. Backend inserts the org_wallets row for that chain.
