At Eiger, we are implementing the integration between Axelar and Solana.

This PR introduces the necessary logic for the ampd component, including:

  • The Solana message verifier handler.
  • The Solana verifier set verifier handler.
  • The logic required to validate Solana addresses.

Both verifier components share the same Solana transaction fetch and log parsing logic, which facilitates identifying event sequences within Solana programs execution outputs.

Todos

  • Unit tests
  • Manual tests (pending - waiting Axelar contract deployment approval)
  • Documentation
  • Connect epics/issues

Steps to Test

  1. Configure ampd with an updated ampd.toml file, pointing to a local tofnd setup.
  2. tofnd must be up and running.
  3. Compile and start the ampd daemon.
  4. Execute the memo program flow, which sends a message from Evm to Solana and viceversa. Scripts can be found at solana-axelar-scripts

Expected Behaviour

It should forward GMP messages from one chain to the another, passing them through the axelar devnet network.

Other Notes

Manual testing is missing because we are waiting for Axelar contract approval.

* Add Solana account parsing tools.
* Add solana verification functionality

* Add unit tests to Solana message verifier

* Refactor

* Solana msg verifier reshape (#4)

* remove comment

* Use Solana types from Solana crates

We were using hand crafted Solana types for interacting with RPC.

* refactor: make clippy happy

* Add some traces to Solana msg verifier

* Remove outdated todos

* refactor: re-use already calculated variable

* Clarify test code usage

* Solana msg verifier, try till one program log matches gw event

* Add note to axelar to review when in PR

* fail if tx_id is not found in signatures

* Always fail on chain at handler level

* Handle errors in case a tx cannot be found (finish the handler)

* Remove commented code

* Use original type from solana-axelar repo

* Ensure that we verify sender address in sol msg verifier

* Do not panic on PartialEq

* refactor: clippy

* remove no longer used code

* Add more tests definition to solana msg verify iteration logic
