Issuing a token#

🔗 From EIP-0004

Ergo supports custom tokens as first-class citizens.

  • A special register R2 of a box contains (tokenId -> amount) pairs.
  • A box can contain at most 255 secondary tokens.
  • However, there are also indirect limits:
    • a box can be no more than 4 kilobytes
    • tokens add to the computational cost of the transaction.
