Allium’s Geographic Intelligence schema answers two questions: where is this wallet? and how does stablecoin value move between geographies? The first is served by addresses_geography (country-level attribution with conviction levels, ~20M addresses). The second is served by the daily geo corridors — every stablecoin transfer across 30 chains, with each leg resolved to a geography where the data honestly supports it, and an explicit measurability grade where it does not.
Not every address — and not every transfer — can be geographically attributed. Measurability is a first-class dimension of this schema, not an assumption: see Geo-Measurability. Volume that cannot be attributed is retained and graded, so every cut reconciles back to total transfer volume.

Schema Location

All tables are in the allium_identity.geo schema in Snowflake, in two groups:
  • Address attributionaddresses_geography: country + conviction per wallet (chainevm/solana/tron)
  • Daily geo corridorscorridors_tiered_daily (full grain), corridor_matrix_daily (country↔country), country_flows_daily (per-country in/out), corridors_coverage_daily (measurability dashboard) — per-chain values across 30 chains, daily from 2026-01-01
Migration note. The former master_list, coverage_summary, and weekly corridor/flow tables have been retired from the public schema. Country-level summaries and cross-border flows are now served by the daily corridor tables above, which supersede them with finer grain (daily, per-chain, per-classification), explicit measurability tiers, and volume that reconciles to transfer totals.

How a transfer becomes a corridor

Unhosted legs resolve through addresses_geography (high-confidence attributions only). Exchange legs have no single country — they fan out into a weighted distribution over the exchange’s user geography, with the top-5 global exchanges deliberately held at region grain (APAC / Americas / EMEA). DeFi and infrastructure legs are structurally unattributable and labeled as such rather than guessed.
