From 8549d75432df4d087f758a89cf5d19f2eec8d932 Mon Sep 17 00:00:00 2001 From: JojoFlex1 Date: Sat, 28 Mar 2026 02:35:41 +0300 Subject: [PATCH] feat: Add Oracle-Verified KPI Vesting Triggers (#145 #92) - kpi_engine.rs: write-once idempotent KPI flag, oracle config storage, verification log, ComparisonOperator reused from existing oracle.rs - kpi_vesting.rs: vault-level gate, attach_kpi_gate, require_kpi_gate_passed - kpi_test.rs: 14 tests covering idempotency, gate enforcement, log, config - lib.rs: DataKey variants (KpiConfig/KpiMet/KpiLog), module declarations, 5 public contract fns (attach_kpi_gate, verify_kpi_gate, get_kpi_status, get_kpi_threshold, get_kpi_log) KPI flag is write-once: once verified true it can never be unset. Gate is opt-in per vault. No clock dependency - metric-based only. Pre-existing lib.rs parse errors (duplicate slash_unvested_balance, unclosed for loop) are unrelated and should be tracked separately. --- contracts/vesting_contracts/src/kpi_engine.rs | 188 +++++++++++++ contracts/vesting_contracts/src/kpi_test.rs | 250 ++++++++++++++++++ .../vesting_contracts/src/kpi_vesting.rs | 97 +++++++ contracts/vesting_contracts/src/lib.rs | 59 +++++ 4 files changed, 594 insertions(+) create mode 100644 contracts/vesting_contracts/src/kpi_engine.rs create mode 100644 contracts/vesting_contracts/src/kpi_test.rs create mode 100644 contracts/vesting_contracts/src/kpi_vesting.rs diff --git a/contracts/vesting_contracts/src/kpi_engine.rs b/contracts/vesting_contracts/src/kpi_engine.rs new file mode 100644 index 0000000..a670bc4 --- /dev/null +++ b/contracts/vesting_contracts/src/kpi_engine.rs @@ -0,0 +1,188 @@ +// Issue #145 / #92 — Oracle-Verified KPI Vesting Triggers +// KPI Engine: stores config, verifies oracle values, flips idempotent flag. + +use soroban_sdk::{contracttype, symbol_short, Address, Env, Symbol, Vec}; +use crate::oracle::ComparisonOperator; + +// ── Storage key symbols ─────────────────────────────────────────────────── + +pub fn kpi_config_key(vault_id: u64) -> (Symbol, u64) { + (symbol_short!("KpiCfg"), vault_id) +} + +pub fn kpi_met_key(vault_id: u64) -> (Symbol, u64) { + (symbol_short!("KpiMet"), vault_id) +} + +pub fn kpi_log_key(vault_id: u64) -> (Symbol, u64) { + (symbol_short!("KpiLog"), vault_id) +} + +// ── Types ───────────────────────────────────────────────────────────────── + +/// On-chain config for one vault's KPI gate. +#[contracttype] +#[derive(Clone, Debug)] +pub struct KpiOracleConfig { + /// Soroban contract that exposes `query_kpi(metric_id: Symbol) -> i128` + pub oracle_contract: Address, + /// Metric identifier forwarded to the oracle (≤ 10 chars). + /// Example: symbol_short!("TW_FOLL") for Twitter followers. + pub metric_id: Symbol, + /// Numeric threshold.
