Precompiled Contracts
Introduction​
Similar to Ethereum, in addition to standard opcodes, the EVM offers more advanced functionalities in the form of precompiled smart contracts. These contracts are bundled with the EVM at fixed addresses and can be called like a standard contract.

FRC20-FRA precompile contract​
We have an ERC20 interface compatible implemenation of FRA. We can interact with this address within ERC20 interface to control your evm FRA as if it's an FRC20 token.
