Address validation & Gas management for NCW

Developer Discussion
1

Hi Team,

  1. Can we do external address validation on fireblocks? If yes, please share api?

  2. We are using Fireblocks to build a non-custodial wallet for our users. Does fireblocks enable us to make gas fee for our users from a different account, so our users don’t need to bother about getting base asset for transfers? Can we try this in sandbox?

Also team, for the 2nd point if there’s a example on how to do a gasless tx please link that , cause cant find any documentation or anything regarding on how to do gasless tx in ncw fireblocks wallets

Hi Kena, This is Mohammed from Fireblocks.
We do not have any API endpoint for external address validation. Can you please shed some light on what is expected from address validation?
Unfortunately, we do not support gasless transactions on NCW wallet.

Hi Mohammed,

Currently, there is no way we can validate on Fireblocks (FB) if a destination address is valid during withdrawal. And if user misses a digit funds can be lost forever. So, we basically wanna know if FB has any API to validate if destination address is correct.
