From 8a3f3016f24e6a27a46604808affd81a1032c9df Mon Sep 17 00:00:00 2001 From: Dollfins <70923667+dollfins@users.noreply.github.com> Date: Fri, 16 Oct 2026 23:41:31 +0000 Subject: [PATCH 1/4] fix: address issues #1617, #1317, #1549, #1548 #1548: Remove dead SOROBAN_SECRET_KEY and ADMIN_SECRET from render.yaml These two secrets were leftovers from closed migrations (#545, #647/#542) and are not read anywhere in backend/src. KEEPER_SECRET_KEY is the actual key used for on-chain cancel actions. #1549: Exclude wallet-gated routes from sitemap Routes /dashboard, /streams/create, /activity, /incoming, /settings require authenticated wallet and show empty/prompt states to crawlers. Only the landing page is genuinely public and crawlable. #1317: Add yield strategy interface for Auto-Yield & DeFi Lending Pool Integration - Create yield_strategy.rs with YieldStrategy trait (deposit/withdraw/get_exchange_rate) - Add yield_enabled: bool field to Stream struct (defaults to false) - Update all 7 Stream constructions in lib.rs to include yield_enabled: false - Add mock integration tests in test.rs verifying trait dispatch, yield_enabled storage, and mock yield distribution (80/20 split) #1617: Stellar Testnet E2E suite compatibility - All changes default yield_enabled to false, preserving existing behavior - No breaking changes to existing stream operations - Tests verify backward compatibility and new trait interface --- contracts/stream_contract/src/lib.rs | 8 +- contracts/stream_contract/src/test.rs | 75 +++++++++++++++++++ contracts/stream_contract/src/types.rs | 3 + .../stream_contract/src/yield_strategy.rs | 52 +++++++++++++ frontend/src/app/sitemap.ts | 30 -------- render.yaml | 6 -- 6 files changed, 137 insertions(+), 37 deletions(-) create mode 100644 contracts/stream_contract/src/yield_strategy.rs diff --git a/contracts/stream_contract/src/lib.rs b/contracts/stream_contract/src/lib.rs index 5592851b..0dae857e 100644 --- a/contracts/stream_contract/src/lib.rs +++ b/contracts/stream_contract/src/lib.rs @@ -434,6 +434,7 @@ impl StreamContract { schedule: VestingSchedule::Linear, arbiter: None, dispute_status: DisputeStatus::None, + yield_enabled: false, is_allowance_based: false, }, );
