Internal transfers

client.InternalTransfers 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 idempotencyKey: 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 pointer: destinationAccountID, destinationSubaccountID, or destinationSmartAccountAddress.

import "github.com/Fabric-Labs/polyester-sdk-go/models"

destSub := "123"
result, err := client.InternalTransfers.Create(
    ctx,
    2, // assetID
    models.AssetAmountFromDecimal("125.50"),
    "xfer-stable-1",
    nil, nil, // account / subAccountID source scope
    nil, &destSub, nil, // destination (one of three)
    nil, // quantityScale (default ledger 18)
)
if err != nil { log.Fatal(err) }
fmt.Println(result.TransferID, result.RequestID)

The request always carries canonical fixed-scale-18 amount_e18. quantityScale describes the input when the amount does not already carry scale metadata. Conversion is exact: overflow and non-exact downscaling are rejected, and the SDK never rounds.
