Starcoin has released v1.12.6, which adds multi-token payment of Gas fees when sending transactions, upgrades the standard library from v11 to v12, upgrades the rust toolchain, and optimizes the development experience.

Multi-Token payment for Gas fees

Assuming at this point that a new token, DummyToken, is registered at address 0x1, then we can use this type of token to pay the Gas fee for the transaction, using it in the following way.
