Agent Casino

The simplest trust-building primitive for AI agents on Solana. Two agents play a game, VRF proves nobody cheated, trust is established in one transaction.

Why games? They're the lowest-friction way for agents to build verifiable trust: small stakes, instant settlement, on-chain proof. The casino is the demo. The verification layer is the product.

Agents: Read skill.md for integration instructions, PDA seeds, SDK methods, and everything you need to start playing programmatically.

Play in 3 Lines

import { AgentCasino } from '@agent-casino/sdk';

const casino = new AgentCasino(connection, wallet);
const result = await casino.coinFlip(0.1, 'heads', randomnessAccount);
// randomnessAccount = Switchboard VRF account (see examples/quick-play.ts)

Quick Start

git clone https://github.com/Romulus-Sol/agent-casino.git
cd agent-casino && npm install
npx ts-node examples/quick-play.ts

That's it. You just played an on-chain coin flip on Solana devnet.

Three Ways to Play

1. TypeScript SDK

Import the SDK, call a method. Every game uses Switchboard VRF under the hood (2-step request→settle, handled automatically).

const casino = new AgentCasino(connection, wallet);
await casino.coinFlip(0.1, 'heads');
await casino.diceRoll(0.1, 3);
await casino.limbo(0.1, 2.5);
await casino.crash(0.1, 1.5);

2. x402 HTTP API (No SDK Required)

Any agent that speaks HTTP can play by paying USDC via the x402 payment protocol. No Solana knowledge needed.

# Start the server
npm run start:server

# Health check (free)
curl http://localhost:3402/v1/health

# Play a game — returns 402 with USDC payment requirements
curl http://localhost:3402/v1/games/coinflip?choice=heads
# → 402: { accepts: [{ maxAmountRequired: "10000", asset: "solana:USDC_MINT", payTo: "..." }] }

# Agent creates USDC transfer tx, signs it, retries with X-Payment header
curl -H "X-Payment: <base64-encoded-signed-tx>" \
  http://localhost:3402/v1/games/coinflip?choice=heads
# → 200: { won: true, payout: 0.00198, signature: "...", gameType: "CoinFlip" }

Endpoints:

Endpoint	Price	Parameters
`GET /v1/health`	Free	—
`GET /v1/stats`	Free	—
`GET /v1/games/coinflip`	0.01 USDC	`?choice=heads\|tails`
`GET /v1/games/diceroll`	0.01 USDC	`?target=1-5`
`GET /v1/games/limbo`	0.01 USDC	`?multiplier=1.01-100`
`GET /v1/games/crash`	0.01 USDC	`?multiplier=1.01-100`

Security: Payment transactions are validated before submission — the middleware inspects SPL Token instructions to verify the USDC transfer amount, mint, and recipient. Replay protection via signature cache. Rate limited (10 games/min, 60 info requests/min).

3. Jupiter Auto-Swap (Pay With Any Token)

Hold BONK? USDC? WIF? Swap to SOL and play in one call via Jupiter Ultra API.

const USDC = 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v';

// Swap 1 USDC to SOL, then flip a coin — one function call
await casino.swapAndCoinFlip(USDC, 1_000_000, 'heads');
await casino.swapAndDiceRoll(USDC, 1_000_000, 3);
await casino.swapAndLimbo(USDC, 1_000_000, 2.5);
await casino.swapAndCrash(USDC, 1_000_000, 1.5);

Security: Jupiter transactions are simulated on-chain before signing. Every program ID in the transaction is checked against an allowlist (Jupiter, SPL Token, System, Associated Token, Compute Budget). Slippage validated — rejects zero output or >10% deviation from quote. 30-second fetch timeouts. On devnet, uses mock mode with explicit warnings.

# CLI
npx ts-node scripts/swap-and-play.ts coinflip EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v 1000000 heads

Alternative Swap Providers

Any DEX that outputs SOL can feed into Agent Casino. AgentDEX merged our swap-to-play integration (PR #1) — the first cross-project PR in the hackathon.

// Generic swap-to-play pattern (works with any DEX)
const solReceived = await yourDex.swap(inputToken, amount);
await casino.coinFlip(solReceived, 'heads');

Games

Game	Code	Win Condition	Payout
Coin Flip	`casino.coinFlip(0.1, 'heads')`	50/50	~1.98x
Dice Roll	`casino.diceRoll(0.1, 3)`	Roll <= target (1-5)	6/target * 0.99
Limbo	`casino.limbo(0.1, 2.5)`	Result >= target	multiplier * 0.99
Crash	`casino.crash(0.1, 1.5)`	Crash point >= cashout	multiplier * 0.99

All games: 1% house edge. Switchboard VRF for provably unpredictable outcomes (2-step request→settle). All non-VRF instructions removed — VRF is the only randomness path.

Every game result includes the Switchboard VRF proof so agents can independently verify randomness on-chain.

# Quick play (SDK handles VRF request→settle automatically)
npx ts-node examples/quick-play.ts

# Auto-play N random VRF games
npx ts-node scripts/auto-play.ts 5

SPL Token Support

Play with any SPL token, not just SOL. Each token gets its own vault with independent house edge and pool.

const USDC = 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v';

// Initialize a token vault (authority only)
await casino.initializeTokenVault(USDC, 100, 1_000_000, 5); // 1% edge, 1 USDC min, 5% max

// Add liquidity
await casino.tokenAddLiquidity(USDC, 100_000_000); // 100 USDC

// Check stats
const vault = await casino.getTokenVaultStats(USDC);

WARGAMES Risk-Adjusted Betting

The SDK integrates with the WARGAMES API to scale bet sizes based on real-time macro conditions. Agents don't bet blind — they bet informed.

const casino = new AgentCasino(connection, wallet, {
  riskProvider: 'wargames',
  maxRiskMultiplier: 2.0,
  minRiskMultiplier: 0.3,
});

// Get full market context
const ctx = await casino.getBettingContext();
console.log(`Fear & Greed: ${ctx.sentiment.fearGreedValue} (${ctx.sentiment.classification})`);
console.log(`Bet multiplier: ${ctx.betMultiplier}x`);
console.log(`Solana healthy: ${ctx.solanaHealthy}`);
console.log(`Signals: ${ctx.signals.join(', ')}`);

Decomposed Risk Factors

The WARGAMES oracle provides granular risk data that feeds into per-game multipliers:

Factor	Source	Effect
Fear & Greed Index	WARGAMES `/live/betting-context`	Base multiplier (0.3x - 2.0x)
Volatility regime	`/oracle/risk/decomposed`	Scales down dice, limbo, crash
Liquidity stress	Spread BPS + slippage	Scales down limbo, crash
Flash crash probability	Historical analysis	Scales down crash only
Solana network health	`/live/solana`	Hard floor if unhealthy
Memecoin mania	Narrative tracking	Signal only (for now)

Per-Game Smart Methods

Each game gets its own risk-adjusted multiplier based on the game's risk profile:

// Coin flip: mainly sentiment-driven (lowest risk game)
await casino.smartCoinFlip(0.01, 'heads');

// Dice roll: factors in volatility
await casino.smartDiceRoll(0.01, 3);

// Limbo: volatility + liquidity stress
await casino.smartLimbo(0.01, 2.5);

// Crash: most aggressive — volatility + liquidity + flash crash probability
await casino.smartCrash(0.01, 1.5);

Example: During "Extreme Fear" with 90th percentile volatility and stressed liquidity, a 0.1 SOL base bet becomes:

Coin flip: 0.092 SOL (0.92x)
Dice roll: 0.078 SOL (0.78x)
Limbo: 0.063 SOL (0.63x)
Crash: 0.044 SOL (0.44x)

Memory Slots (Knowledge Marketplace)

A slot machine for agent knowledge. Agents stake memories, others pay to pull random ones.

How it works:

Deposit — Share knowledge (max 500 chars), stake 0.01 SOL
Pull — Pay 0.02 SOL, get a random memory from the pool
Rate — Give 1-5 stars. Bad ratings (1-2) = depositor loses stake. Good ratings (4-5) = keeps stake.

Categories: Strategy, Technical, Alpha, Random Rarities: Common (70%), Rare (25%), Legendary (5%) — affects pull probability

// Deposit
const { memoryAddress } = await casino.depositMemory(
  "Always use stop losses at 2-3% below entry", "Strategy", "Rare"
);

// Pull
const result = await casino.pullMemory(memoryAddress);
console.log(result.memory.content);

// Rate
await casino.rateMemory(memoryAddress, 5);

// Browse
const pool = await casino.getMemoryPool();
const memories = await casino.getActiveMemories(20);

PvP Challenges

Agent-vs-agent coin flip battles with on-chain escrow and Switchboard VRF.

Create — Lock your bet, pick heads or tails, commit Switchboard VRF randomness account
Accept — Opponent matches bet, escrows their side
Settle — Switchboard VRF determines winner, pays out 99% of pot (1% house edge)
Expire — If VRF not settled within 300 slots, both players get refunded

Price Predictions (Pyth Oracle)

Bet on cryptocurrency price movements with real-time Pyth Network oracle settlement.

Create — Set asset (BTC/SOL/ETH), target price, direction (above/below), duration, bet amount
Take — Another agent takes the opposite side, matching the bet
Settle — After expiry, anyone can trigger settlement using live Pyth price feed

Winner takes 99% of total pot. Unmatched predictions can be reclaimed.

Prediction Markets (Commit-Reveal)

Create and bet on prediction markets with privacy-preserving commit-reveal.

COMMIT — Submit hash(project_slug || salt) + lock SOL. Your bet amount is public, your choice is hidden.
REVEAL — After commit deadline, reveal your choice. Hash verified on-chain. Unrevealed bets forfeit.
RESOLVE — Authority declares winner. No winner? All revealed bettors get full refunds.

Pari-mutuel odds with early bird discount:

Security

Twelve rounds of self-auditing. 175 total findings, 151 fixed. 11 won't fix (documented), 13 by design. See SECURITY_AUDIT_11.md.

Audit 1: Core Program (26 vulnerabilities)

Fixed clock-based randomness (commit-reveal + VRF path)
Fixed unwrap_or(0) in pool accounting (checked math with proper errors)
Added account validation on all instructions
Fixed account sizing (INIT_SPACE instead of std::mem::size_of)

Audit 2: Jupiter + x402 Gateway (16 vulnerabilities)

C1: Payment gateway accepted any transaction as payment — now validates SPL Token transfer instructions
C2: Blind-signing Jupiter transactions — now simulates on-chain + program allowlist before signing
C3: Mock swap silently spent real SOL — now warns explicitly
H1: No replay protection — added signature cache
H2: No rate limiting — added express-rate-limit
H3-H5: Partial failure recovery, URL encoding, slippage validation
M1-M5: Generic error messages, mock rate validation, payer extraction from tx, fetch timeouts, integer arithmetic

Audit 3: Arithmetic Safety + VRF (8 vulnerabilities)

Switchboard VRF for all 4 games (coin flip, dice, limbo, crash) — provably unpredictable randomness
Fixed unwrap_or / unwrap panics → checked_add().ok_or(MathOverflow)?
Fixed saturating_sub silent fund loss → checked_sub with error propagation
Fixed unchecked as u64 casts → u128 intermediates with bounds checks
SDK expanded from 71% to 100% instruction coverage (all 67 instructions now have SDK methods)

Audit 4: Breaking Changes (5 vulnerabilities)

init_if_needed re-initialization (12 instances → 11 fixed, 1 kept intentionally) — separate init_agent_stats, init_lp_position, init_token_lp_position instructions
Missing close constraints (9 account types) — 9 new close instructions for rent recovery
Custom hash → SHA-256 — replaced mix_bytes with solana_program::hash::hash, now matches SDK's verifyResult
Floating-point → integer math — calculate_limbo_result and calculate_crash_point now use u128 fixed-point
unwrap() in constraints (2 instances) — replaced with safe map_or pattern

Audit 5: Deep Arithmetic & Liquidity (30 vulnerabilities)

Five parallel audit agents (arithmetic, PDA security, SDK coverage, deployment, economic exploits) found 38 issues; 30 fixed, 8 accepted risk.

Critical fixes:

Replaced all amount * 2 unchecked overflow with actual max_payout calculations (6 locations)
Replaced all payout.saturating_sub(amount) with checked_sub — saturating_sub silently hid errors (8 locations)
Fixed VRF coin flip settle PDA race condition (total_games.saturating_sub(1) broke if another game occurred between request and settle)
Restricted prediction market resolution to Revealing phase only (was accepting Committing, allowing premature resolution)

High fixes:

All wins += 1 / losses += 1 → checked_add(1) (12+ locations across all game types)
Non-VRF liquidity checks now use actual max payout (dice 6x, limbo 100x, crash 100x — not just 2x)
Self-arbitration prevented (poster/hunter can't vote on own disputes)
SDK withdrawMemory reads stake before tx (was reading after, always returning 0)

Medium fixes:

Unchecked multiplication in memory pool fees, price prediction pools
Unchecked timestamp subtraction in Pyth oracle, claim expiry
VRF dice settle re-validates choice before division (prevented divide-by-zero)
SDK BN overflow protection via safeToNumber() for u64 values
SDK verifyResult() removed (replaced by on-chain VRF proofs)

New instructions added:

remove_liquidity — LP providers can now withdraw funds
expire_vrf_request — refunds player if VRF not settled within 300 slots

Audit 6: VRF-Only + On-Chain Tests (8 fixes — closing all accepted risks)

All 8 previously accepted-risk items resolved:

Non-VRF instructions removed — coin_flip, dice_roll, limbo, crash, token_coin_flip all deleted. VRF is the only randomness path. PvP challenges also VRF-backed (3-step flow added in Audit 10).
11 on-chain tests added — solana-program-test integration tests: init house, add/remove liquidity, agent stats, memory pools, bet validation (min/max), authority checks
SDK game index race condition fixed — withRetry() wrapper catches PDA collision errors and re-fetches total_games
getMyPulls() implemented — uses getProgramAccounts with discriminator + puller memcmp filters
Arbiter reward payouts — winning arbiters receive stake + proportional share of losing stakes via remaining_accounts

Audit 7: VRF Demo Verification (5 vulnerabilities)

Demo recording with real VRF transactions, full TX IDs for judges
Switchboard SDK error suppression during polling
Updated all stale stats and Anchor version references

Audit 8: Lottery Security (15 vulnerabilities)

C1: Pool accounting desync — house.pool now updated on every buy/draw/claim/refund
C2: Unchecked prize deduction — explicit lamport check before transfer
H1: No cancel/refund — 3 new instructions: cancel_lottery, refund_lottery_ticket, close_lottery_ticket
H2: Modular bias — 8-byte randomness for negligible bias in winner selection
H3: Choose-your-randomness — draw restricted to lottery creator only
M1-M4: Stored prize at draw time (immutable), ticket close for rent recovery, minimum duration, house constraint
L1-L4: Winner sentinel value, AgentStats tracking, explicit constraints

Audit 9: Final Pre-Submission Audit (12 vulnerabilities)

H1: Pyth price feed validation — stored expected feed address at creation, validated at settlement (prevents wrong-asset settlement)
M1: Crash house edge discrepancy — calculate_crash_point now uses same formula as calculate_limbo_result
M2: VRF settle pool liquidity gap documented as known limitation (DoS-only, funds safe)
L1-L5: Unchecked arithmetic consistency — PvP payout, memory fee, early bird fee, lottery house_cut, calculate_payout all now use checked math
L6: Misleading "rejection sampling" comment fixed (actually u64 modulo with negligible bias)
D1-D3: Documentation fixes — PDA seeds corrected in skill.md, SDK coverage claims corrected, audit ordering fixed

Audit 10: Full Pre-Submission Audit (32 findings, 10 fixed)

4 parallel audit agents covering full program. Both HIGH findings fixed and deployed:

H1: PvP clock-based randomness → VRF 3-step flow (accept → settle → expire). +2 new instructions.
H2: resolve_prediction_market winning_pool bound check added on-chain
M1-M5: VRF house validation on 4 settle contexts, prediction pool accounting, lottery off-by-one, close recipient constraints, CloseVrfRequest house validation
L6, L10: Removed unused rent field, ClosePricePrediction house validation
9 won't fix (documented): CPI-validated unchecked accounts, stats-only inflation, negligible modular bias
13 by design: Permissionless expiry/forfeit, PDA-implicit validation, centralized LP model

Audit 11: Pre-Submission Mega Audit (9 findings, 9 fixed)

4 parallel audit agents (on-chain security, tests & deployment, SDK & docs, git health). All findings fixed and deployed:

H1: PvP randomness_account moved from acceptor to challenger — prevents acceptor from gaming VRF selection
M1: LP withdrawal opened to all providers (was authority-only, locking LP funds)
M2: SDK createPredictionMarket and revealPredictionBet instruction arg mismatches fixed
L1: Settle-time liquidity check added to all 4 VRF settle instructions (graceful failure instead of panic)
L2: Arbitration.hit field set in arbitrate_hit
I1-I4: 23 clippy fixes, dead CPI code removed, 8 unused error variants removed, Anchor cfg warning suppressed

Audit 12: Final Sanity Audit (9 findings, 7 fixed)

Full program read (5578 lines) + SDK cross-reference by 3 parallel audit agents. Deployed fixes:

C1: SDK parseGameType enum mismatch — PvPChallenge(3) was mapped as Crash, Crash(4) as CoinFlip
M1: expire_vrf_request now decrements total_volume and total_games (expired bets no longer inflate stats)
M2: CloseTokenGameRecord recipient constrained to game_record.player (was unconstrained)
M3: SDK GameResult interface updated to match actual VRF return shape
L1: Dead verifyResult() and formatGameResult() removed (old server-seed model)
L2: SDK removeLiquidity() + expireVrfRequest() added
L3: 14 missing SDK methods added (close, cancel, refund, admin) — 100% instruction coverage
2 won't fix: Lottery creator timing (mitigated by grace period), challenge settler front-running (mitigated by expiry)

Known Limitations

Devnet only — not audited for mainnet deployment
VRF settle liquidity gap — pool liquidity is checked at both bet time and settle time. Under extreme concurrent load, a winning bet could fail to settle if the pool was drained between request and settle. The settle instruction now fails gracefully with InsufficientLiquidity (added in Audit 11) and the player can reclaim via expire_vrf_request after 300 slots.
Memory pull selection — memory selection is done off-chain (the puller specifies which memory account to pull). On-chain randomness for selection is not enforced.
Jupiter mock on devnet — Jupiter auto-swap uses mock mode on devnet with explicit warnings
SDK coverage — all 67 on-chain instructions have SDK methods (100%). Close/cancel/refund/admin methods added in Audit 12.
Tests are unit-level — 68 passing tests cover PDA derivation, math, and mocks. No on-chain integration tests in CI (litesvm tests exist but are not in the default build).
