Transfers - Allium Documentation Hub

stablecoins.core.transfers is the unified record of every on-chain stablecoin movement across all chains Allium supports. Each row captures sender, receiver, raw and normalized amounts, USD value at the time of transfer, and transaction context. This table replaces crosschain.stablecoin.transfers. Key additions in the new schema: product_id (canonical stablecoin identifier), is_native (distinguishes chain-native issuance from bridged representations), stablecoin_type (backing model), and usd_exchange_rate. For single-chain workloads, use <chain>.stablecoins.transfers instead — identical schema without the chain column. For background on how Allium maps on-chain events to the transfer schema:

Token Transfers

Sample Queries

All USDT-family transfers on Ethereum (replaces base_asset = 'usdt') The legacy base_asset column grouped tokens by ticker and is removed. Filter by product_id via the catalog to include native USDT and bridged or DeFi-wrapped variants:

select *
from ethereum.stablecoins.transfers
where product_id in (
    select product_id
    from stablecoins.registry.catalog
    where underlying_product_id = 'usdt'
        or product_id = 'usdt'
)
limit 100

On stablecoins.core.transfers, add a chain filter instead of using the per-chain table. Weekly unique senders and total volume of USD stablecoins across all chains, last 6 months

select
    date_trunc('week', block_timestamp) as week,
    chain,
    token_symbol,
    count(distinct from_address) as unique_senders,
    sum(amount) as transfer_volume
from stablecoins.core.transfers
where block_timestamp > current_timestamp - interval '6 months'
    and currency = 'usd'
group by all
order by 1 desc
