MintShield Failure-isolated execution
Coston2 114
Execution safety for Flare Smart Accounts

Let the action fail.
Keep the FXRP safe.

You mint FXRP through a Flare Smart Account and use it immediately in one signed transaction. If the next step fails, MintShield returns your exact FXRP instead of leaving your mint stuck — no second XRPL payment, no recovery flow to learn.

One payment. One protected outcome.

From XRP payment to safe execution.

MintShield keeps planning, wallet approval, protocol proof and application execution visibly separate. Every gate has a clear job.

Router yalnızca girilen exact FXRP için approve edilir. Desteklenen action post-condition’ı sağlamazsa miktar Personal Account’a döner.

Aynı hata, iki farklı sonuç

Desteklenen action revert ettiğinde MintShield outer operation’ı başarıyla kapatır. Çıplak akışta ise ikinci ödeme ve kurtarma gerekir.
