Function: createBatchStream(uint256[] calldata tokenIds, address onBehalfOfOwner)

The function create a stream for each token in tokenIds. An aggregate allocation is transferred to the owner of the NFT, and a fee is transferred to the caller if they are not the NFT's owner.

Inputs

• tokenIds

  • Validation: The current block number is checked to be greater than vestingStartBlock. The tokenId is checked to be a valid credentialNFT by the ownerOf function.

  • Impact: It prevents the creation of a stream twice or the creation of a stream for a non-existing NFT.

• onBehalfOfOwner

  • Validation: Each stream is checked to be owned by the onBehalfOfOwner address and to have not being already created.

  • Impact: It prevents the creation of a stream for a token not owned by onBehalfOfOwner.

Branches and code coverage (including function calls)

Intended branches

• A stream is created by the owner of the NFT from a token array. The instant amount is properly transferred.

  Test coverage

• A stream is created by another user. The instant amount and the fees are properly transferred.

Negative behavior

• A stream created for the second time reverts.

  Test coverage

• A stream created before the vesting starts reverts.

  Test coverage

• A stream created for an array containing an invalid identifier reverts.

  Test coverage

• A transfer failure during a stream creation reverts.
