This updates the build system and other places in the code to use Foundry's
forge
instead of truffle to build and test the included smart contracts (used as part of the EVM chain integration with Xaya X). The unit tests have been recoded in Solidity. Truffle has been sunset, so this ensures that the code is future proofed.The Docker file is updated to be based on Ubuntu now instead of Alpine, since it seems very hard to get the prebuilt Foundry binaries, which depend on glibc, to run on there.
The integration testing framework (which is then also used by any game integration tests running on EVM chains such as Soccerverse) is updated to use Foundry's
anvil
instead ofganache
, too.
