feat: add L1->L2 hashes #1186

Closed PhilippeR26 closed 2 months ago

PhilippeR26 commented 2 months ago

Motivation and Resolution

Solves issue #1178 Provides functions to calculate L1->L2 hashes. L2->L1 hash has already been implemented in PR #702

Usage related changes

2 new functions :

L1->L2 message Hash :

const l1L2MessageHash = hash.getL2MessageHash(l1FromAddress, l2ToAddress, l2Selector, payload, l1Nonce);

L1->L2 transaction Hash :

const l1L2txH = hash.calculateL2MessageTxHash(l1FromAddress, l2ToAddress, l2Selector, payload, constants.StarknetChainId.SN_SEPOLIA, l1Nonce);

All inputs have to be recovered from a L1 explorer.

Development related changes

Some code from PR #702 is also valid for this PR. So this code has been refactored in hash.solidityUint256PackedKeccak256()
hash.getSelector() has been improved to accept also as input the type BigNumberish. All messaging functions have been added in the guides.
