* Add network name display instead of chainID * Add display of correct ticker along with network * Add FTM * Clang-format * Add comment in python script * Rename SIZE_MAX to MAX_SIZE * Change %u to %d in printf * Remove needless PIC * Update comment about get_chain_id() * Update example script to follow EIP155 * Remove unused PIC calls * Add whitespace between ticker and amount when using EIP155 * Remove decimal config per network, set back 18 everywhere * Adapt u32_from_BE to swith cases * Remove chainid from signTx.py * Switch to switch in stead of if in get_chain_id * Revert "Remove chainid from signTx.py" This reverts commit 454e09f280ec3e3ec1c7d7cc0027247ef4390088. * Change Ethereum chainid to 1 * Rename chainid_step to network_step * Adapt finalizeParsing to new chainid for Ethereum * Update snapshots * clang-format * Fix network display logic for clones * Fix tests * Add clone tests Co-authored-by: TamtamHero <10632523+TamtamHero@users.noreply.github.com>
