This PR breaks up the EVM NTT Manager into two components, the existing
NttManager
, which works as always and a newNttManagerWithoutRateLimiting
, which does not do rate limiting. This allows integrators to chose whether or not they wish to use rate limiting.This is done by adding an abstract contract called
NttManagerBase
which contains most of the implementation, except for rate limiting.The
NttManagerWithoutRateLimiting
does not implement rate limiting, but it does implement thatIRateLimiter
interface. This is being done to maintain ABI compatibility between the two contracts.This change increases the size of the
NttManager contract
by 67 bytes (leaving 90 bytes free).The
NttManagerWithoutRateLimiting
contract has 6689 bytes free.
