Blinko

Play Blinko headlessly on Abstract. Provably fair Plinko with on-chain settlement.

Important

• This skill signs on-chain transactions that spend real ETH. Use a dedicated hot wallet with only the funds you're willing to risk.
• Each game costs gas (Abstract chain) on top of your bet amount.
• Your private key is used locally to sign messages and transactions. It is sent to the Abstract RPC and Blinko API as signed outputs only, never as plaintext.
• Agents can invoke this skill autonomously when installed.

Quick Start

Play a Game

export WALLET_PRIVATE_KEY=0x...
node scripts/play-blinko.js 0.001

Check Stats

node scripts/stats.js 0xYourAddress profile

Scripts

Script	Purpose
play-blinko.js	Play a full game (auth → create → commit → play → settle)
stats.js	View profile, games, leaderboard, honey balance

Play

export WALLET_PRIVATE_KEY=0x...
node scripts/play-blinko.js [betETH] [--hard] [--v2]

Flag	Effect
--hard	Hard mode (0% main game RTP, must trigger bonus to win)
--v2	V2 algorithm and config

Examples:

node scripts/play-blinko.js 0.001                # Normal, 0.001 ETH
node scripts/play-blinko.js 0.005 --hard          # Hard mode
node scripts/play-blinko.js 0.002 --v2            # V2 algorithm
node scripts/play-blinko.js 0.003 --hard --v2     # V2 hard mode

Bet limits: 0.0001 - 0.1 ETH

Stats

node scripts/stats.js <address> [command] [limit]

Command	Shows
profile	Name, honey, game stats, streak
games [N]	Last N games with results
leaderboard	Top 10 + your rank
honey	Honey balance breakdown

How It Works

API → Chain → API → Chain

1. Login — Sign message with wallet, get JWT
2. Create — API generates game seed, returns server signature
3. Commit — Call createGame() on-chain with ETH bet + random salt
4. Play — API combines seeds, simulates physics, returns result
5. Settle — Call cashOut() (win) or markGameAsLost() (loss) on-chain

All games are provably fair via commit-reveal scheme.
