Doing TopUp from existing AssetLock for more than 5 Dash fails.

[kxcd]

I am doing TopUp from an existing AssetLock (don't ask) value greater than 5 Dash, more than 100 Dash to be fair and the DET shows me this error message.

Error topping up identity: Dapi client error: transport error: grpc error: status: Internal, message: "Internal error", details: [], metadata: MetadataMap { headers: {"grpc-accept-encoding": "identity", "grpc-encoding": "identity", "content-type": "application/grpc+proto", "date": "Mon, 21 Apr 2025 11:02:45 GMT", "x-envoy-upstream-service-time": "19", "server": "envoy"} }

Note that this is after the u64 fix was made in rust-dpp and then a new build of DET was created.

Tested using: https://github.com/dashpay/dash-evo-tool/releases/tag/v0.8.5 Note the fix included in this one dashpay/dash-evo-tool#205

Hi @kxcd — I took a look at the Platform-side topup code and the asset lock validation pipeline. The credit conversion and balance checks all use u64 throughout, with saturating_mul for the duff-to-credits conversion, so I don't see an obvious overflow or panic path for large values on the current codebase.

Given that this was reported on v1.8.0 (April 2025) and Platform has gone through significant changes since then (v3.0.1+, including various asset lock related work), it's possible this was resolved as a side effect of other fixes.

Going to close this for now due to age, but if you're still seeing this on a current Platform version, please reopen and we'll dig deeper. Thanks for the detailed report!
