Have you checked if our smart contracts work with Rust 1.82.0?
I remember we had an error related to the heap memory provided to them or something like that

Generally, the rust toolchain, that should be used in the smart contract development, should be done with stable toolchain which is 1.93.1 at the moment, the wasmvm toolchain version is just constraints for the wasmvm build itself, but as we use the wasmvm binary, we are safe to use any stable version of toolchain to build the smart contract. i used 1.86.0, because it has been used in the recent rust optimizer of cosmwasm.

This version is the only version that is compatible with cosmwasm v3+, so i thought it would be good to have update to this version so we would be compatible with the next version.

So we are safe to say we can use recent stable version, but i upgraded to v 1.86.0 as minimum requirement for the recent rust optimizer.

I have changed the rust toolchain everywere in the rust libs and contracts in bridge, so far i have not seen any failure from those usages, but i will update you when I am done with the recent tests.

During the call with the team, it was decided to stick into 1.81 as this version is the current toolchain version of the rust optimize v0.16
