Product overview: Funds & Transfers.
Deposit addresses
addr, err := client.Deposit.CreateAddress(ctx, 1, nil, nil)
listed, err := client.Deposit.ListAddresses(ctx, 1, nil, nil)See Deposit.
Trading withdraws
API-key bots prepare and persist the complete signed request before sending:
import (
"github.com/Fabric-Labs/polyester-sdk-go/models"
"github.com/Fabric-Labs/polyester-sdk-go/services"
)
prepared, err := client.Withdraw.PrepareAPIKeyToFunding(services.PrepareAPIKeyWithdrawParams{
AssetID: 2, Amount: models.AssetAmountFromDecimal("100.00"),
AmountScale: 2, IdempotencyKey: "withdraw-stable-1",
})
if err := os.WriteFile("prepared-withdraw.bin", prepared.RequestBytes(), 0600); err != nil {
log.Fatal(err)
}
result, err := client.Withdraw.SubmitPrepared(ctx, prepared)Wire amount_e18 always uses fixed scale 18. Input scale conversion is exact, overflow checked,
and never rounded. Restore persisted bytes with services.PreparedTradingWithdrawFromBytes and
submit them unchanged after an outcome-unknown error.
Details: Withdrawals.
Internal transfers
dest := "123"
_, err := client.InternalTransfers.Create(
ctx, 2, models.AssetAmountFromDecimal("10"),
"xfer-1", nil, nil, nil, &dest, nil, nil,
)See Internal transfers.
Security
High-risk money movement may require additional account controls. See Withdrawals & transfers security.
