@Embark

Dear colleagues, what are your thoughts about adding a restricted transfer function where the token minter can define conditions for transfers in a future version of ICRC?

Use-Cases include transfer-level conditions such as lock-up periods, identities to be known or accepted by Internet Identity personhood check as well as token-level conditions i.e. the token contract enforces a maximum number of investors or a cap on the percentage held by any single investor.

function canTransfer(address _to, uint256 _value, bytes _data) external view returns (byte, bytes32);
function canTransferFrom(address _from, address _to, uint256 _value, bytes _data) external view returns (byte, bytes32);
