we shuold probably update this to also be u128; i think where possible we should update amount to u128 since that is the default balance type it seems

[Dentosal]

Balances are u128. But the amount to transfer is u64. You cannot transfer more than u64::MAX.

[zees-dev]

Interesting; i raised this because I repeatedly saw amount as u128 when tracing up the layers of abstraction:
https://github.com/FuelLabs/fuel-core/blob/85b2356d510a30cffaa8be7015203bb8ac30fee6/crates/client/src/client/types/balance.rs#L13

But it seems like the rust sdk will first need to account for this; i guess maybe a future release

[zees-dev]

All looks good!
Converting to draft however since this release contains breaking changes; it will be blocked until #7235 is merged.
