Introduction
Note
The functionality in this release is purpose-built for the EOS → A token migration in the Vaulta EVM deployment. It is not intended for use by other EVM instances or unrelated token migrations.
Vaulta EVM Contract v2.1.0 introduces the ability to update the Vaulta EVM deployment's gas token and perform a token swap as part of the migration.
Read on for more details.

New actions (swapgastoken and migratebal) and logic updates to withdraw, handle_account_transfer, and evm_contract::transfer have been introduced to enable the migration from EOS to A as the gas token in Vaulta EVM deployment.
