[jamie088]

I tested it several times but couldn't reproduce it. @fieldtheory123 Could you please test it?

[taariq]

@jamie088 does this smell like bloxroute issue?

[jamie088]

No, it is not bloxroute issue. This issue happens when estimating gas before running the tx and this means the parameters or contracts have an unknown error. But I tested it several times and also checked your tx and did not find an error. Could you please test it again?

[taariq]

@jamie088 how does the service estimate gas? It makes an RPC call via bloxroute. Is this incorrect?

I am not the only person having this issue. If there's another way that the call to get gas estimate is made, let me know, but I suspect this is RPC endpoint issue. Correct me if there's another way to get gas estimate. This issue is impacting front-end experience.

Closing until it hurts.
