Stablecoins
Get macro metrics to granular transaction details of Stablecoin movements on chain.
Our crosschain.stablecoin
schemas allow users to investigate onchain stablecoin activity across multiple blockchains.
The stablecoin vertical supports currencies aside from usd (e.g. cny, jpy, try, eur, cad, etc.)
Table of main stablecoins (inclusive of other currencies) and their respective contract addresses across various chains.
Transfers of all stablecoins indexed by Allium. Includes all stablecoins on crosschain.stablecoin.list
Pre-built metrics for stablecoin transfer activity (e.g. volume & transaction counts), aggregated by day, chain and token address. Includes adjusted activity metrics.
Chain Coverage
We are currently working on expanding stablecoin coverage for more chains and add on a case by case basis. Please reach out to us if you have any questions or would like to request coverage for a specific chain.
Stablecoins List
The stablecoin list includes a list of curated stablecoins with various denominations. This list is used to identify the list of stablecoins to be included in the crosschain.stablecoin.transfers
table.
Unique Key: chain
, address
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.
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 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.
The 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
.
Stablecoin Transfers
The stablecoin transfers table contains all on-chain transfers of stablecoins found in the stablecoin list. This table allows users to aggregate stablecoin activity across multiple chains while also fetching granular transfer details.
A short primer on Allium's transfer schema and how it maps to the on-chain data can be found here:

Stablecoin Metrics
The crosschain.metrics.stablecoin_volume
table aggregates stablecoin activity from crosschain.stablecoin.transfers
by day, chain and token address.
It includes adjusted activity metrics using the following methodologies:
Single Direction Max Transfer - only the largest stablecoin amount transferred within a single transaction is counted
Single Direction Net Transfer - the largest net stablecoin amount transferred per token, to a single address, for each transaction, is counted
Entity Adjusted, Single Direction Max Transfer - in addition, to applying the Single Direction Max Transfer logic, this methodology also uses labels & heuristics to remove bot related activity (e.g. if an address does more than 1,000 transactions and $10m in transfer volume in a rolling 30-day window), or intra-exchange volume (i.e. when transfers are made between two CEX/DEX addresses)
