(async () => {
    try {
        curve.init('https://nodes-testnet.wavesnodes.com', 'Keeper', { signer, chainId: 84 });
    } catch (err) {
        if (error.code === '14') {
            alert('Create WavesKeeper Account');
        } else {

        }
    }
})()

Signer

import curve from "@curvefi/waves-api";

(async () => {
    const signer = new Signer({
        // Specify URL of the node on Testnet
        NODE_URL: 'https://nodes-testnet.wavesnodes.com'
    });
    signer.setProvider(new ProviderWeb('https://testnet.waves.exchange/signer/'));

    await curve.init('https://nodes-testnet.wavesnodes.com', 'Signer', { signer, chainId: 84 });
