Kunal Arora	c032b8ba27	chore: refactor MessagIdHook/ISM tests into a common `ExternalBridgeTest` contract (#4490 ) ### Description We currently have 6 different versions of ISMs derived from AbstractMessageIdAuthorizedIsm: - OPL2ToL1 - ArbL2ToL1 - OPStack (L1->L2) - ERC5164 - LayerZero - PolygonPOS But all of them have their own custom test suite right now, with widely overlapping testing areas. For standardizing the tests, I've created a base test contract `ExternalBridgeTest` that handles the common tests. This has a few benefits: - harder to miss tests for known pitfalls like msg.value or asynchronicity assumption for verifyMessageId - less code duplication with each additional Ism I have moved OPL2ToL1, ArbL2ToL1, OPStack, and ERC5164 to the new base test, and I'll forgo the rest for now because of the time sensitivity of audit remediations. I've created an issue tracking the remaining work here: https://github.com/hyperlane-xyz/issues/issues/1384 ### Drive-by changes None ### Related issues Related to https://github.com/chainlight-io/2024-08-hyperlane/issues/3 ### Backward compatibility Yes ### Testing Unit	3 months ago

Kunal Arora	6f377f1743	feat: implement `OPL2ToL1Ism` contracts (#4319 ) ### Description Implementing the `OPL2ToL1Hook` and OPL2ToL1Ism` contracts for using the Optimism native bridge for sending messages from the L2 to L1. - Optimism needs double call encoding for the direct portal call because the portal itself calls the l1Messenger which then directs it to the ism. ### Drive-by changes None ### Related issues - fixes https://github.com/hyperlane-xyz/issues/issues/1346 ### Backward compatibility Yes ### Testing Unit testing with mocks for OP contracts	4 months ago

Kunal Arora	f733379488	feat: support Arbitrum L2->L1 post dispatch hook (#3853 ) ### Description - Contract support for the enabling postDispatch hook with the Arbitrum nitro bridge from L2 to L1 - asynchronously via executeTransaction call to verifyMessageId first and then the relayer calling the verify message with no metadata (note: this supports msg.value) - synchronously via a single verify call which in turn calls executeTransaction on outbox to gets the message verified in the verifyMessageId (note: this doesn't support msg.value as ism.verify isn't payable) - Added a script for deploying the hook and ISM since the sdk doesn't support it yet. ### Drive-by changes - changing the type from "rate_limited_hook" to "RATE_LIMITED" to maintain consistency ### Related issues - fixes https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/2846 ### Backward compatibility Yes ### Testing Unit and e2e with arbitrumsepolia->sepolia	5 months ago

Lee	ae0990a0b3	LayerZero Hook and ISM (#3102 ) ### Description - Implements LayerZero V1 and V2 hook with V2 ISM. - V2 ISM is backwards compatible i.e., V1 hook (which uses V1 endpoint to send) can send to V2 ISM (which uses V2 endpoint to receive). See [here](https://docs.layerzero.network/explore/migration#configuring-ultralightnode301) for configuration. - V2 uses `AbstractsMessageIdAuthorized*`. In. other words, hook passes messageId through LayerZero, which stores into ISM to be used when relayer calls `verify()` . - Includes unit test for both V1 and V2 hook and ISM. - V1 uses official LayerZero endpoint mock. ### Drive-by changes <!-- Are there any minor or drive-by changes also included? --> ### Related issues - Implements #2853 ### Backward compatibility Yes ### Testing Manual/Unit Tests	9 months ago

Trevor Porter	1a64cef37e	Refactor key management in infra and key funder (#3023 ) ### Description * Remove the `bank` role, which we haven't used since the inception of abacus / hyperlane * Big changes to `key-utils.ts` so that there's a single source of truth on what kind of keys are used depending on the role & chain. Before this was sprinkled in a few different places * You can now get an object of `{ [chain]: { [role]: keys[] } }`, so it's super clear what kind of key relates to which chain. For example, before we would use the AWS-based relayer key for EVM chains, and then a GCP-based relayer key for non-EVM chains. But this wasn't really honored by key funder - it had no way of knowing to only fund the AWS relayer on EVM chains, and only fund the GCP relayer on non-EVM chains. Same situation for Kathy, where we want to use AWS keys for EVM chains but the GCP key for non-EVM chains * On v2 and prior to that we were using the AWS-based key for Kathy. Originally, we also launched v3 this way. However it was changed on v3 to use the GCP key for Kathy, causing us to fund both types of addresses on v3. This makes it more clear that we should be using the AWS-based key for Kathy on EVM chains ### Drive-by changes <!-- Are there any minor or drive-by changes also included? --> ### Related issues <!-- - Fixes #[issue number here] --> ### Backward compatibility <!-- Are these changes backward compatible?

Kunal Arora	e06fe0b327	fix:enable `DefaultFallbackRoutingIsm` through non-factory deployment (#3009 ) ### Description - `DefaultFallbackRoutingIsm` needs the mailbox address which meant `DefaultFallbackRoutingIsmFactory` needed the mailbox address which is not ideal. So, I switched to non-factory deployments for this specific ISM type. - CLI does the ISM deployment inside core deployment instead of ISM first and core then. - Using the coreDeployer's `cachedAddresses` to store the latest ie toplevel ISM. ### Drive-by changes - fixed bug in `ismFactory.fromAddressMap` to not use the multiprovider filtered by contract map. This is undesirable as CLI user can provide chain selection and artifacts which doesn't include all the chains in the configs (and when we call `multiprovider.getDomainId` for the origin which may now be missing from the filtered MP, we get an error). ### Related issues - fixes https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/2895 ### Backward compatibility Yes ### Testing Manual through CLI	1 year ago

Yorke Rhodes	50f04db1fa	Make merkle proofs optional on multisig ISM (#2173 ) ### Description Validators currently sign `(root, index)` checkpoints and during verification, a `message` is passed as calldata, an `id()` is derived, and a `proof` of `id()` at `index` in `root` is verified This provides “all or nothing” censorship resistance guarantees because a validator can only sign roots to allow any contained messages to be processed. We have considered alternatives where validators sign `message` directly and we lose censorship resistance in exchange for eliminating merkle proof verification gas costs. However, if validators sign `(root, index, message)` tuples, we can skip merkle proof verification on the destination chain while still maintaining censorship resistance by providing two valid metadata formats: 1. existing validator signatures and merkle proof verification of inclusion 2. including merkle proof verification for pathway where validators are censoring `message` It’s worth noting the validator is required to index event data to produce this new signature format. However, this does not require historical indexing and new validators being spun up can simply begin indexing from tip. See https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/2187 for validator changes See https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/2248 for relayer and e2e test changes ### Drive-by changes Merkle index also optional ### Related issues - Fixes https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/2192 ### Backward compatibility - new ISM deployment is necessary (we could upgrade implementation in theory) - Validator and relayer upgrades ### Testing Unit (fuzz) Tests, E2E tests	2 years ago

Asa Oines	e8d90775f7	Add Aggregation ISM (#1737 ) ### Description This PR introduces the Aggregation ISM, which requires interchain messages to be verified by an m-of-n ISM set. This PR also introduces a new MultisigISM, which does not make use of the "commitment" optimization in its metadata. The previous MultisigISM has been moved to LegacyMultisigISM. Both AggregationISM and MultisigISM have abstract contracts that require `valuesAndThreshold` implementations. This PR implements versions with static m-of-n sets, using the EIP-3448 MetaProxy standard. These implementations are intended to be combined with a future RoutingISM implementation to replace LegacyMultisigISM. ### Drive-by changes - genhtml in solidity code coverage ### Related issues - Fixes #1522 ### Backward compatibility _Are these changes backward compatible?_ Yes ### Testing _What kind of testing have these changes undergone?
