From f2f9ef1accb6328410c793c093b7f2516317e2b4 Mon Sep 17 00:00:00 2001 From: Deiadara Date: Thu, 25 Jun 2026 14:28:42 +0300 Subject: [PATCH 1/9] feat(test-express): add express-execution reimbursement monitor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Observe-only monitor for Axelar express-execution reimbursement via the Axelarscan GMP API. Two modes: scan recent express transfers per chain, or watch a single source tx through both phases (express-executed → executor reimbursed). Adds the CLI subcommand, the test_express module (gmp_api + types + orchestrator), a workflow-dispatch CI workflow, and AXE_STATE docs. v1 is monitor-only; originating a qualifying express transfer is a follow-up. --- .github/workflows/test-express-execution.yml | 78 +++++++ AXE_STATE.md | 22 ++ src/cli.rs | 27 +++ src/commands/mod.rs | 1 + src/commands/test_express/gmp_api.rs | 67 ++++++ src/commands/test_express/mod.rs | 215 +++++++++++++++++++ src/commands/test_express/types.rs | 173 +++++++++++++++ src/main.rs | 18 ++ src/timing.rs | 9 + 9 files changed, 610 insertions(+) create mode 100644 .github/workflows/test-express-execution.yml create mode 100644 src/commands/test_express/gmp_api.rs create mode 100644 src/commands/test_express/mod.rs create mode 100644 src/commands/test_express/types.rs diff --git a/.github/workflows/test-express-execution.yml b/.github/workflows/test-express-execution.yml new file mode 100644 index 0000000..ba010d9 --- /dev/null +++ b/.github/workflows/test-express-execution.yml @@ -0,0 +1,78 @@ +name: Test Express Execution + +# Observe-only monitor for Axelar express-execution reimbursement.
