Please see Emre's comment: https://github.com/wormhole-foundation/wormhole-connect/issues/2724#issuecomment-2385376525

The problem is the error from RPC about the batch size when requesting token balances:

Error: could not coalesce error (
  error={ "code": -32062, "message": "Batch size too large" },
  payload={
    "id": 2,
    "jsonrpc": "2.0",
    "method": "eth_getBalance",
    "params": [ "0x49887a216375fded17dc1aaad4920c3777265614", "latest" ]
  },
  code=UNKNOWN_ERROR,
  version=6.13.2
)

The default Kaia RPC in Connect and (if any) the override in Portal Bridge is not accepting larger RPC payloads to get the token balances. When I replaced it with our paid RPC in 1Password, it started working.

I think Portal Bridge needs to use another RPC for klaytn. I see that it's using the free one: https://rpc.ankr.com/klaytn
