Implement a connector for AMPL token

[cenwadike]

Hello,

I would like to Implement a connector for AMPL token.

It is will have these features:

• Contract on Solidity/Ethereum side that can lock and unlock AMPL.

• When AMPL gets unlock, the amount should be correct given possible rebases that have happened

• Contract on NEAR side that can mint/burn nAMPL.

• Contract on NEAR side would also receive rebase events from AMPL ERC-20 contract and adjust total supply as well.

The following additions will be made:

• In bridge-token-factory/

  • add rebase_event.rs
  • to lib.rs, add:
    • rebase()
    • finish_rebase()

• to bridge-token/lib.rs

  • add ft_rebase()

• in bridge-common/

  • to result_types.rs add:
    • RESULT_PREFIX_REBASE
    • struct Rebase{}
    • impl Rebase{}

The following changes will be made:

• To bridge-common/

  • in prover.rs

    • struct EthEvent{ rebaser_address, … }

    • impl EthEvent{ // add rebaser_address }
