client.internal_transfers moves funds between Polyester accounts without touching a chain:
from your source scope to another root account, a subaccount, or a smart-account address.
Transfers are idempotent on idempotency_key: repeat requests with the same key return the
existing transfer instead of creating a second one.
Methods
| Method | Summary |
|---|---|
create | Create (or return) an idempotent internal transfer. |
Create
Provide exactly one destination: destination_account_id, destination_subaccount_id, or destination_smart_account_address.
result = await client.internal_transfers.create(
asset_id=2,
quantity="125.50",
idempotency_key="xfer-stable-1",
destination_subaccount_id="123",
)
print(result.transfer_id, result.request_id, result.quantity)| Field | Required | Notes |
|---|---|---|
asset_id | yes | Ledger asset id |
quantity | yes | Decimal string or AssetAmount |
idempotency_key | yes | Reuse on retry |
| destination (one of three) | yes | Account / subaccount / smart-account address |
account / sub_account_id | no | Source scope override |
quantity_scale | no | Default ledger scale 18 |
The request wire field is always amount_e18. quantity_scale declares the input scale and the
SDK rescales exactly to scale 18, with checked overflow and no rounding. For example, AssetAmount.from_scaled(125, scale=2) is encoded as 1_250_000_000_000_000_000 (1.25e18). Inexact downscales are rejected.
