Minting large sums of libra on testnet

Testnet

Thanks for creating libra!
Currently, minting errors out with large quantities.

Maximum seems to be at 1 million libra, not 1000000000000.

@satoshi: There’s a hard limit on minting 1 million Libra coins for a mint operation at the moment.

Also, unfortunately there’s a bug in the CLI where it reports the max mint amount in Microlibra whereas the input is in Libra.

Thanks for reporting! We have a fix for this and will probably push it out tomorrow.

Hi @Ray, We’ve only announced the testnet. There is nothing you can purchase at this time. For testing purposes, new coins can be minted – check out the documentation: https://developers.libra.org/docs/my-first-transaction
