* LockItIn is open-source, autonomous blockchain infrastructure that enables
10
* peer-to-peer commitments on natural-language statements resolved by VERO.
11
*
12
* VERO ("Verification Engine for Resolution Outcomes") is the protocol's
13
* DAO-elected oracle system. The DAO may vote to change the underlying
14
* oracle provider, model, prompt, or any oracle behavior at any time via
15
* timelocked governance proposals (30-day notice once timelock is activated).
16
*
17
* This smart contract:
18
* • Is non-custodial and holds user funds only as required for autonomous settlement
19
* • Does not provide custodial accounts or intermediary services
20
* • Does not set terms, take principal exposure, or determine outcomes
21
* • Executes deterministically based on immutable logic and VERO responses
22
*
23
* Parties who interact with this contract explicitly agree that:
24
* • Outcomes are determined solely by the VERO response (YES / NO / VOID)
25
* • The DAO governs all aspects of VERO and may change it at any time
26
* • Funds may be permanently forfeited due to unfavorable outcomes or protocol fees
27
* • Smart contract, oracle, and blockchain risks are inherent and assumed
28
*
29
* THIS SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND.
30
* USE AT YOUR OWN RISK.

41
* VERSION 1.3.0 CHANGES:
42
* - Added bytes32 tag field for frontend filtering and ecosystem decentralization
43
* - Tag is indexed in CommitmentCreated event for efficient log queries
44
* - Enables independent frontends to build curated feeds without centralized indexers

* ═══════════════════════════════════════════════════════════════════════════════
47
* TAG SYSTEM (bytes32) — Frontend / Indexing Metadata
48
* ═══════════════════════════════════════════════════════════════════════════════
49
*
50
* Overview:
51
* The `tag` field is OPTIONAL metadata for event indexing and UI filtering.
52
* It does NOT affect settlement, fees, oracle behavior, or any protocol logic.
53
* This protocol does NOT interpret, validate, or enforce tags.
54
*
55
* Recommended Derivation:
56
* Canonical string: "<namespace>:<key>"
57
* Encoding: UTF-8 bytes
58
* Hash: bytes32 tag = keccak256(bytes(canonical))
59
*
60
* Namespace Guidelines:
61
* Use an identifier you "control" socially to avoid collisions:
62
* - A domain name: "lockitin.xyz"
63
* - An ENS name: "lockitin.eth"
64
* - A stable org/community identifier
65
* Lowercase recommended to avoid accidental duplicates.
66
*
67
* Key Guidelines:
68
* A lowercase slug is recommended. Charset: [a-z0-9._-]
69
*
70
* Examples:
71
* Canonical String Hash
72
* ───────────────────────── ────────────────────────────────
73
* "lockitin.xyz:featured" → keccak256("lockitin.xyz:featured")
74
* "lockitin.xyz:politics" → keccak256("lockitin.xyz:politics")
75
* "alice.eth:my-feed" → keccak256("alice.eth:my-feed")
76
* "farcaster.xyz:frames" → keccak256("farcaster.xyz:frames")
77
*
78
* Special Values:
79
* bytes32(0) is valid and means "no tag" (untagged commitment).
80
*
81
* Client display:
82
* - On-chain stores only the hash (bytes32). Human-readable labels are a client concern.
83
* - Each frontend may maintain its own registry (bytes32 -> string) for known tags.
84
* - Unknown tags can be displayed as hex.
85
*
86
* Security Note:
87
* Tags are UNTRUSTED user input. Any user can set any tag hash. Treat
88
* tags as hints for indexing/filtering, not as authentication or
89
* endorsement. Use allowlists/curation for "official" feeds.

92
* VERO Oracle System (Multi-Source Architecture)
93
* ═══════════════════════════════════════════════════════════════════════════════
94
*
95
* VERO ("Verification Engine for Resolution Outcomes") is the DAO-elected
96
* oracle that resolves commitments. All VERO parameters are DAO-governed
97
* with an optional 30-day timelock for transparency:
98
* - veroSource: JavaScript execution logic (AI routing + multi-source data fetch + evaluation)
99
* - apiEndpoint: LLM provider API URL
100
* - defaultModel: AI model identifier
101
* - systemPrompt: Instructions sent to the AI for evaluation
102
* - veroTemperature: Model randomness setting
103
* - donId: Chainlink DON identifier
104
*
105
* v1.2 introduces intelligent data source routing:
106
* - Step 1: AI analyzes statement and decides data source
107
* - Step 2: Fetch data from Twelve Data (prices) OR Exa (web) OR Visual Crossing (weather)
108
* - Step 3: AI evaluates statement against fetched data
109
*
110
* Provider-agnostic secrets (SEARCH_API_KEY, LLM_API_KEY, TWELVE_API_KEY, WEATHER_API_KEY):
111
* - SEARCH_API_KEY: Exa API key for web search
112
* - LLM_API_KEY: xAI/Grok API key for AI inference
113
* - TWELVE_API_KEY: Twelve Data API key for market prices
114
* - WEATHER_API_KEY: Visual Crossing API key for weather data
115
*
116
* Current default configuration:
117
* - Search: Exa API (context string, 5 results, live crawl preferred)
118
* - Market Data: Twelve Data API (crypto, stocks, forex, commodities)
119
* - Weather: Visual Crossing API (historical and forecast, location-based)
120
* - Inference: xAI Grok (grok-4-1-fast-non-reasoning, temperature 0)
121
*
122
* Safety Philosophy:
123
* - Default to VOID (refund both) on any ambiguity
124
* - 7-day emergency void escape hatch if oracle fails
125
* - 30-day timeout void if no one calls resolution
126
* - Mutual exit: both parties can back out while Locked
127
* - No pause function - immutability over control
128
*
129
* Fee Structure (all DAO-adjustable within bounds via Governor):
130
* - Creation fee: $0-$10, starts at $0
131
* - Resolution fee: $0.20-$5, starts at $1 (from pot)
132
* - DAO fee: 0.1%-10%, starts at 0.3% (% of pot)
133
* - Tx Builder fee: 0-1%, starts at 0.2% (% of pot)
134
* - $5 USDC minimum commitment per side
135
* - LOCKIT holders get 0-50% discount on protocol fees
