Description
Play Blinko (on-chain Plinko) headlessly on Abstract chain. Use when an agent wants to play Blinko games, check game stats, view leaderboards, or track honey rewards. Handles the full commit-reveal flow including API auth, on-chain game creation, simulation, and settlement.

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

How It Works
API → Chain → API → Chain
- Login — Sign message with wallet, get JWT
- Create — API generates game seed, returns server signature
- Commit — Call
createGame()on-chain with ETH bet + random salt - Play — API combines seeds, simulates physics, returns result
- Settle — Call
cashOut()(win) ormarkGameAsLost()(loss) on-chain
All games are provably fair via commit-reveal scheme.
Game Mechanics
- 10 balls dropped through 8 rows of pins
- Bin multipliers: 2x, 1.5x, 0.5x, 0.2x, 0.1x, 0.1x, 0.2x, 0.5x, 1.5x, 2x
- Bonus: Collect B-O-N-U-S letters to trigger bonus rounds (up to level 9)
- Honey: Earned by hitting special pins (requires a referrer)

Usage Guidance
This skill appears to do exactly what it says (play Blinko on Abstract) and contains the code to sign and submit real ETH transactions. Key points before installing: (1) The skill requires your private key (WALLET_PRIVATE_KEY) — this gives full control of that wallet. Use a dedicated hot wallet with only the funds you are willing to lose. (2) Registry metadata omitted the env var; ask the publisher why that mismatch exists and confirm the skill's provenance. (3) The skill talks to hardcoded endpoints (https://api.blinko.gg and https://api.abs.xyz) and a hardcoded contract address — verify those addresses are legitimate before use. (4) If you install, prefer manual invocation (disable autonomous agent actions or require confirmation) and inspect/run the code in an isolated environment. (5) If you only want read‑only info, consider using stats.js with a watch‑only address instead of providing a private key. If you need higher assurance, ask the publisher for a signed source/release or run the scripts on a throwaway wallet with minimal funds first.
Capability Analysis
Type: OpenClaw Skill
Name: blinko
Version: 1.1.1
This skill is classified as suspicious due to its inherent high-risk capabilities, specifically requiring and using a `WALLET_PRIVATE_KEY` from environment variables to sign on-chain transactions that spend real ETH, as seen in `SKILL.md` and `scripts/play-blinko.js`. While the documentation is transparent about these actions and the code appears to handle the private key locally for signing (not exfiltrating it in plaintext), the direct interaction with a hot wallet and the ability to spend funds on-chain introduce significant financial risk. All network interactions are with the explicitly stated `https://api.blinko.gg` and `https://api.abs.xyz` endpoints.
Capability Assessment
Purpose & Capability
The name/description and included scripts (play-blinko.js, stats.js) are coherent: the skill logs in, requests a server seed, calls createGame/cashOut on the on‑chain contract, and queries stats from api.blinko.gg. However the registry metadata at the top claimed no required env vars, while SKILL.md and the scripts clearly require WALLET_PRIVATE_KEY. That metadata mismatch is an inconsistency the publisher should explain.
Instruction Scope
SKILL.md and the scripts are specific about actions: sign a login message, obtain a JWT, call the Blinko API, call Abstract RPC to create and settle on‑chain games, and show stats. The instructions do not attempt to read unrelated files or hidden credentials. They do transmit signatures and JWTs to api.blinko.gg and send signed transactions to the RPC endpoint (expected for this purpose).
Install Mechanism
There is no installer that downloads arbitrary archives; this is instruction + source files with a simple package.json (ethers dependency). Risk is limited to running npm install / node on the files you download; no obscure remote installers or shortener URLs are used.
Credentials
The skill requires a single, highly sensitive environment variable: WALLET_PRIVATE_KEY (declared in SKILL.md metadata). That is proportionate to playing an on‑chain game, but it grants full control of the wallet's funds. The earlier registry section incorrectly listed no required env vars — this mismatch is concerning. No other credentials are requested, which is expected, but the private key risk is material.
Persistence & Privilege
always:false (good). The skill indicates agents may invoke it autonomously (default platform behavior). Because the skill can sign and submit transactions that spend ETH, autonomous invocation increases risk — consider restricting autonomous use or requiring user confirmation before any transaction is sent.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install blinko - After installation, invoke the skill by name or use
/blinko - Provide required inputs per the skill's parameter spec and get structured output
