FutureToken¶

ITTFutureToken¶

Interface for TTFutureToken, which tracks ownership of TokenTable unlocking schedules.

This page describes version 2.7.7. The implementation is TTFutureToken (version() returns 2.7.7-TTFutureToken plus the EVM suffix). In npm package 2.7.0 the interface is called ITTFutureTokenV2 and has no enableTransfer, isTransferable or DidEnableTransfer.

ITTFutureToken extends IERC721AQueryableUpgradeable (ERC721A) and IVersionable. The token ID of each FutureToken is the actualId of its unlocking schedule, and the token's owner receives the schedule's claims. The token name is Future <project token name> and the symbol FT-<project token symbol>.

While transfers are disabled, transferFrom and safeTransferFrom revert with NotPermissioned.
