Crate pallet_evm_precompile_assets_erc20

Structs

• Erc20AssetsPrecompileSet
  The following distribution has been decided for the precompiles 0-1023: Ethereum Mainnet Precompiles 1024-2047 Precompiles that are not in Ethereum Mainnet but are neither Astar specific 2048-4095 Astar specific precompiles Asset precompiles can only fall between 0xFFFFFFFF00000000000000000000000000000000 - 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF The precompile for AssetId X, where X is a u128 (i.e.16 bytes), if 0XFFFFFFFF + Bytes(AssetId) In order to route the address to Erc20AssetsPrecompile, we first check whether the AssetId exists in pallet-assets We cannot do this right now, so instead we check whether the total supply is zero. If so, we do not route to the precompiles This means that every address that starts with 0xFFFFFFFF will go through an additional db read, but the probability for this to happen is 2^-32 for random addresses
