  • USDV behaves like a normal ERC-20 tokens with slightly more gas in transfer for recording the coloring metadata.

  • The gas cost of USDV remint function on Ethereum is a function of the number of colors involved in the reminting operations. It grows linearly in proportion to the colors involved. The avg 151k is a good estimate of use cases.

  • VaultManager is the vault responsible for USDV issuance.
