Table Columns
| Column Name | Description |
|---|---|
| currency | The ISO currency code (e.g. usd, eur, jpy, xau (gold)) of the stablecoin, in lower case. |
| base_asset | The underlying stablecoin for stablecoins that are issued by third parties, such as bridges, or defi-protocols. |
| address | The contract address of the stablecoin. The contract address for a stablecoin is unique on the blockchain. |
| symbol | Symbol of the token, in lower case by default. |
| name | Name of the token. |
| decimals | Decimals of the token, used for normalization. This field is optional and may be null. |
| chain | Blockchain of the where the stablecoin is based, in lower case. |
| is_bridge | When TRUE, this means that the stablecoin is bridged. |
- Stablecoin Base Assets
Stablecoins can be broadly classified into their underlying peg mechanism.They can be fiat-backed, commodity-backed, algorithmic, crypto-backed (DAI), or a hybrid of many.For fiat-backed stablecoins, there is often a regulated entity involved in the issuance and management of the stablecoin ensuring its stability and value. These entity-issued stablecoins are said to be “native”.Using USDC as an example, there are multiple variants of USDC:
- A native stablecoin refers to a stablecoin issued directly from a regulated entity such as Circle, which is redeemable for the underlying asset (be it US Dollars, Euros, etc). Circle maintains a list of their native stablecoins here.
- A bridged stablecoin refers to a stablecoin that is issued by a third-party application (e.g. Wormhole, Axelar, etc.) issued by locking a native stablecoin in a smart contract on one blockchain to mint a bridged stablecoin on another blockchain.
- A defi variant stablecoin refers to a stablecoin issued by a decentralized application (e.g. Compound, Aave, etc.) and is backed by the underlying collateral assets in the protocol. One example is Aave interest-bearing USDC (aUSDC).
base_asset field in the stablecoin list aims to capture the underlying stablecoin of a token. For example, Axelar USDC, Aave USDC, and Bridged USDC.e on Avalanche will all be labelled as usdc its base_asset.
