Supported Currencies

The use of all tokens come - at the very least - with regulatory risk and smart contract risks. Some other risks are included below.
Support for these tokens is not an endorsement of the safety of these tokens.
Trelis currently supports the generation of payment links for the following tokens:
  • USD Coin (USDC) - a fiat-backed stablecoin that aims to track the US dollar.
  • Ether (ETH).
All supported tokens come with inherent risks, not limited to those described below.


USDC is a token issued by Circle Internet Financial Limited ("Circle").
As per the Circle website as of July 13th 2022:
"Known as a fully-reserved stablecoin, every digital dollar of USDC on the internet is 100% backed by cash and short-dated U.S. treasuries, so that it’s always redeemable 1:1 for U.S. dollars."
Details of the reserves backing USDC are available here.
Substantial risks associated with USDC include, but are not limited to:
  1. 1.
    Uncertainty over USDC tokenholder access to fiat dollar reserves in the case of bankruptcy of Circle [Journalistic Report from Matt Taibbi].
  2. 2.
    Possibility of token blacklisting. The number of access denied USDC tokens is small to date, but remains a possibility in certain circumstances [See June 2022 Report].
  3. 3.
    Regulatory Risk. The regulatory environment around stablecoins is volatile and may pose risks to the operation of Circle and/or the legality of USDC in certain jurisdictions.


Ether (Eth) is a token whose price is volatile when measured in US dollars.
Ether (Eth) is used to pay for gas on Ethereum. It is also issued as a reward to those who stake Ether to secure the Ethereum network.
