+## Listing an account's SUPRA movements
+
+Which method lists them depends on where the account holds SUPRA:
+
+- Coin layout (Mainnet and Testnet accounts created before governance enables feature 64 or 65): SUPRA is in the
+  account's `CoinStore<SupraCoin>`, and `account_coin_transactions` lists its movements.
+- Primary-store layout: SUPRA is in the account's primary fungible store, and `account_coin_transactions` lists
+  none of its movements. While feature 64 or 65 is enabled, registering SUPRA creates the primary store instead of a
+  `CoinStore<SupraCoin>`, so new accounts hold SUPRA there; so does an account that migrated its SUPRA. On a chain
+  created with features 64 and 65 on, such as Devnet on `supra_node_v12.0.0`, no account has a
+  `CoinStore<SupraCoin>`. Use `account_history` with the category `fa` (nodes from `supra_node_v12.0.0`) or
+  `account_fa_transactions`. SUPRA transfers emit `0x1::fungible_asset::Withdraw` and `Deposit` events, whose `store`
+  field names the fungible store, not the account, and no `0x1::coin` events.
+
+```python
+entries, cursor = await client.account_history(address, categories=["fa"])
+async for entry in client.iter_account_history(address, categories=["sent", "fa"]):
+    print(entry["categories"], entry["transaction"]["hash"])
+async for transaction in client.iter_account_fa_transactions(address):
+    print(transaction["hash"])
+```
