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.

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) or markGameAsLost() (loss) on-chain
All games are provably fair via commit-reveal scheme.
