The Trust Testnet is currently under developer preview phase. There's still a lot of improvement under way but the whole system is mostly working. To try everything about the Trust EVM:
Connecting to the network with your favorite wallets.
Get some test tokens from the faucet.
Make some transfers.
Setting up IDEs to play with smart contracts!
Thanks to the high API compatibility of the Trust, most popular wallets and IDEs should work on Trust EVM seamlessly.
