Cannot IBC 100+ USDY to Penumbra

[UnityChaos]

Appears to be a bug once total raw amount goes over 10^20 due to 18 decimals on USDY.

I'm 90% sure that this happening during a call to simulate tx here.

Here is an example message:

{
    "typeUrl": "/ibc.applications.transfer.v1.MsgTransfer",
    "value": {
        "sourcePort": "transfer",
        "sourceChannel": "channel-89",

        },

        "timeoutTimestamp": "1725627000000000000",
        "memo": ""
    }
}

The cosmjs SigningStargateClient is not able to simulate the fee for this transfer 🤔 . It throws precisely here.

Here is the bug, it's on the penumbra frontend side:

   "token": {
            "denom": "ausdy",
            "amount": "1.12e+20"
        },

Amount should not be formatted in that way. Can close this here. Will fix on the other end.
