Unrecognized MultiChain metadata, any way to improve the output?

[roderik]

I made a transaction with metadata (sha256 hash in hex format) and the explorer shows Unrecognized MultiChain metadata for the transaction. Is there a format to use that is recognised?

[bitcartel]

What command did you run to create the transaction with metadata?

Please copy the JSON output from multichain-cli mychain getrawtransaction TXHASH 1 and let me know which output contains the metadata and what you see in the explorer.

I'm using the json-rpc interface, so here are the requests, data and responses. The metadata is created in PHP as follows:

bin2hex(hash('sha256', "some content")));

Sending the transaction:

Thanks, will look into this.

[bitcartel]

Updated. Explorer now shows the hex metadata.

Works great, thanks
