How to display custom ERC-20 tokens on a custom chain (Kaia Mainnet) in Wallet Services UI?

Embedded Wallets (Web3Auth)
1

Hello,

We’re using @web3auth/modal v10. We’ve enabled Kaia Mainnet in the dashboard’s
Chains & Networks section, and the network appears correctly in the Embedded
Wallet UI. The native KAIA token is shown.

However, we’d like to display an ERC-20 token that exists on Kaia Mainnet in
the same Wallet UI. We’ve checked the following and none seem to work:

  1. Dashboard’s chain config for Kaia only has metadata fields (chain ID, RPC,
    explorer, decimals, etc.). There is no field for a token list URL, indexer
    endpoint, or custom ERC-20 tokens.

  2. The Wallet UI’s Settings has only “Add Custom Network” (which is for chains,
    not tokens) — there’s no “Add Token” / “Import Token” button.

Questions:

  1. Is there a supported way to display ERC-20 tokens on a custom EVM chain
    like Kaia in the Wallet Services UI?
  2. Is there a dashboard option or SDK option we’re missing?

Thanks!

Hi — I’m on the MetaMask & Web3Auth team. You’re correct: Embedded Wallets (Web3Auth modal) currently only surface the chain’s native asset for custom EVM networks. There’s no dashboard “Add Token” or SDK method to inject/display specific ERC‑20s in the Embedded Wallet UI today.

Workarounds:

  • If you control the app around the Embedded Wallet, fetch ERC‑20 balances yourself (RPC balanceOf or an indexer/token‑list service) and display tokens in your UI alongside the embedded wallet.
  • If you need full token management inside the wallet UI, consider building a custom wallet experience with the MetaMask SDK for complete control (more dev work).

If you’d like, I can escalate this as a feature request to the product team. If so, please confirm and share the Kaia chainId and the token contract address (symbol + decimals optional) so I can include the details. Otherwise someone from the team will follow up with next steps.
