A: The collab contract automatically splits any revenue made from sales of an OBJKT among the collaborators defined by the contract, as as per the relative shares of each collaborator.
A: Each collaborator receives a share of the payments relative to the shares defined on the contract. For example, if a contract has 4 collaborators (A, B, C, and D), they could have their shares equally distributed (25% each) or not (A: 50%, B: 30%, C: 10%, D: 10% or any arbitrary distribution).
A: There is no hard-limit, but we have not yet tested a contract with more than 10 collaborators. Larger contracts may run into Tezos gas or storage limits. We will update this when we have more concrete data on this topic.
A: Yes, but only if the OBJKT was minted by the collab contract. The collab contract automatically splits any XTZ payments made towards the contract's address, so provided the contract address is the creator of the OBJKT then it will be the recipient of secondary sale royalties, and hence those payments will also be automatically split among the collaborators.
A: Currently only XTZ is tested and supported, but in the future it might also work for any fungible FA2 token on the Tezos blockchain, even wrapped tokens.
A: Not quite. You can transfer existing OBJKTs to a collab contract's address, and these can be manually swapped and sold. The sale revenues will be split among the contract collaborators, however any secondary market royalties are still only paid to the original minter, and hence not available to the collab contract for splitting.
A: Not at the moment, but this is something that will be considered in future versions.
A: Not at the moment. This is something we are considering for a future version, when more advanced permission controls are in place. For now the OBJKT will only appear under the profile of the collab contract's address. You may advertise it on your social media channels in order to raise awareness to it and at the same time confirm that you consented to that particular collaborative work.
A: Not at the moment. Currently only the contract's manager can mint. This is something that will likely change in future versions.
A: Tips allow the collaborators to automatically make small donations to entities of their choosing each time a collab OBJKT generates revenue, by sharing some of that revenue with those benefactors according to the tip shares defined in the contract.
A: Provided the OBJKT was minted by the collab contract then all revenue generated by that OBJKT, including all royalties, will generate tips according to the tip shares defined in the contract.
A: Absolutely. That is one of the reasons why a collab contract includes a tips section. See: What are tips/benefactors in a collab contract?
