Fungible Token (FT)

Example implementation of a Fungible Token contract which uses near-contract-standards.

NOTES:

• The maximum balance value is limited by U128 (2**128 - 1).
• JSON calls should pass U128 as a base-10 string. E.g. "100".
• This does not include escrow functionality, as ft_transfer_call provides a superior approach. An escrow system can, of course, be added as a separate contract.
