There's no official bounty program to "join," but there are tons of ways to earn bounties. If you are doing things that have a positive benefit to the community, let the team know. Finding bugs in anything, helping community members, helping with testnet, translation services, really anything that helps everyone and moves the project forward will likely earn you a bounty. We'll sometimes offer bounties for a specific task and put an announcement on Discord. We will also reward initiative that supports Mochimo (like an entry on the wiki or a well-written Medium article) in proportion to the quality and time invested.
Send your tag to kashmyr[at]mochimo.org. We'll pay out your bounty and send a confirmation email.
Expiration of bounties
Effective June 25, 2019, all bounties awarded are valid and payable for 6 months (180 calendar days) from the date of award. From a long-term perspective, it's undesirable to have coins in limbo and we want to get them to their owners quickly and efficiently.
