estimateFee(). Supplied initial fee overrides remain unchanged.
Set sponsoredGas: true to require Para-paid gas, or sponsoredGas: false for wallet-paid gas.
With true, Para manages nonce, gas limits, fees, and submission. Unsupported nonce, gas/fee/type, or retry
controls return errors; they are never ignored to make sponsorship succeed.
Omitting it selects wallet-paid execution, even for enrolled partners. Explicit sponsorship never falls back to wallet-paid gas;
see Gas sponsorship for eligibility, unsupported combinations, and errors.
For wallet-paid payments that need further attempts while pending, see Automatic fee retry.
TransferRequest does not expose autoRetry; use that guide’s HTTP example.
