Accounts

Frontier provides two different strategies for handling H160 addresses.

H256 -> H160 mapping

The first strategy consists of of a truncated hash scheme, where the first 160 LE bytes of a H256 address are used to form the H160 address.

AccountId32 is the Account type used for frame_system::pallet::Config::AccountId.

The Runtime's Signature type is configured as sp_runtime::MultiSignature, which means signatures can be:

  • Sr25519
  • Ed25519
  • ECDSA

Native H160 via AccountId20

The second strategy consists of using fp-account so that AccountId20 is the Account type used for frame_system::pallet::Config::AccountId.

The Runtime's Signature type is configured as EthereumSigner, which means only ECDSA signatures are supported.
