From 60236e523cd9533750f46df99f71da7d5b71bd05 Mon Sep 17 00:00:00 2001 From: timiturn3r Date: Wed, 30 Sep 2026 23:52:46 +0100 Subject: [PATCH] feat(contracts): emit dedicated ProtocolPaused events on pause toggle (#1517) - Add ProtocolPausedEvent struct and emit_protocol_paused function in events.rs - Invoke emit_protocol_paused inside set_protocol_pause and expose set_emergency_pause in lib.rs - Emit event with topics ["FlowFi", "ProtocolPaused"] containing admin and is_paused status - Add unit tests verifying event emission on pause and unpause - Align storage stream field count and error variants for contract compilation --- contracts/stream_contract/src/errors.rs | 6 ++ contracts/stream_contract/src/events.rs | 26 +++++- contracts/stream_contract/src/lib.rs | 44 +++++---- contracts/stream_contract/src/storage.rs | 3 +- contracts/stream_contract/src/test.rs | 113 +++++++++++++++++++++-- 5 files changed, 164 insertions(+), 28 deletions(-) diff --git a/contracts/stream_contract/src/errors.rs b/contracts/stream_contract/src/errors.rs index cdfacb17..e1283585 100644 --- a/contracts/stream_contract/src/errors.rs +++ b/contracts/stream_contract/src/errors.rs @@ -81,4 +81,10 @@ pub enum StreamError { NotArbiter = 32, /// Allowance-based stream operation failed.
