How GACHAI works

The whole thing is three moves: crank, win, spend.

1. 1Crank a box with USDC. Pick a machine — Bronze, Silver or Gold — and crank it. The outcome is sealed before you pay, so it can’t be changed after. Not by luck, not by us.
2. 2Win AI tokens. Never less than 2×. Every box pays at least twice its price. 1 token = $1 of real API balance — not points, not a voucher, no expiry games.
3. 3Spend through one key. Your tokens sit behind a single API key. Point any OpenAI-compatible app at our endpoint and every model is live — Claude, GPT, Gemini, Llama and dozens more. Metered per call, down to the token.

1. 1Connect a wallet (MetaMask, Coinbase, Rainbow, WalletConnect) or sign in with email — your account is created automatically.
2. 2Deposit USDC on either Base or Solana — open the deposit window from the balance pill in the nav and pick your network. It becomes your Balance, the money you open boxes with. Base credits after a brief on-chain confirmation; Solana after finality (~15s).

Pick a box on the Boxes page and hit Crank. It's paid instantly from your Balance — no wallet popup. Boxes start at $50.

You win AI Credits. The amount depends on the rarity you roll — Common, Rare, Epic or Legendary — and every box pays at least 2× its price in credits, guaranteed by the published odds tables.

Every roll is committed before you pay and verifiable after: the server seals a secret seed and publishes its hash before your payment, then reveals the seed with your result. Check any pull on the Provably fair page.

Every crank is sealed beforeyou pay, so the outcome can’t be changed after — not by luck, not by us. Every crank works like this:

1. 1Commit.Before you pay, the machine commits a sealed hash of your result — public, timestamped, immutable.
2. 2Crank. You pay, payment confirms, the capsule drops.
3. 3Reveal. The seed is published with your result. Anyone can recompute the hash and confirm it matched the commitment.

Not “trust us.” Check us. Every crank ever made is in the public log below with its commitment and reveal side by side — find yours, find anyone’s. (The full cryptographic detail is in Architecture.)

Every account has one key, shown on your Profile. It starts with bb-live- and works like an OpenAI API key — except it spends your won AI Credits instead of charging a card.

Reveal, copy, or rotate it from the profile. Rotating kills the old key immediately — anything still using it gets a 401.

Spending happens in your tool, not on this site. Any app that accepts an OpenAI-compatible API works: point it at the base URL, paste your key, pick a model.

curl https://api.gachai.io/chat/completions \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-4.1-mini","messages":[{"role":"user","content":"Hello"}]}'

In Cursor (or similar tools)

1. 1Open the tool's model settings and find "OpenAI API key" + "Override base URL" (Cursor: Settings → Models).
2. 2Set the base URL to https://api.gachai.ioCopy
3. 3Paste your bb-live- key as the API key.
4. 4Enter one of the available models above as a custom model name. It behaves like OpenAI from there — your credits cover the usage.

1 credit = $1 of model usage. Different models cost different amounts per token — the rate next to each model in the list above — so pricier models use credits faster.

Your credits balance updates on your profile within a few seconds of spending, even when the usage happened in an external tool. When credits run low, crank another machine.

Won credits spend on AI today — but soon they won’t have to stay as compute. Repackagelets you turn the AI tokens you’ve won into something liquid, two ways:

1. 1Convert to GACHAI— claim the platform’s native token at the current rate, then hold it or trade it on the open market. The primary path, and the one the flywheel is built around.
2. 2Resell for USDC— sell your unused credits into the open inference market and settle the proceeds to your wallet in USDC. Capacity-limited while that market grows.

You can preview it now: on your profile, the Repackage card gives a live quote for either path as you type an amount.

GACHAI is backed by revenue, not emissions. The platform’s margin, on every box and every token of inference, is routed on-chain into continuous buy-and-burn. Volume compounds into a shrinking float.

How the 75% is enforced

1. 1The split is codified in an on-chain router— contract logic, not treasury discretion.
2. 2Buys execute on-DEX; burns hit a dead address — every transaction on-chain.
3. 3Cumulative burn surfaced live: verifiable, not asserted.

Under the hood, GACHAI is three isolated systems that share nothing but the ledger: a provably-fair roll engine, a double-entry credit ledger, and an OpenAI-compatible inference gateway. Here’s how each one holds up.

Provably-fair rolls

Every roll is a commit–reveal. Before you pay, the server generates a 256-bit secret seed and publishes its SHA-256 commitment, bound to your pull. The outcome is then derived by HMAC-ing that seed with your client seed and a per-roll nonce — so neither side can bias it: you can’t grind seeds after seeing the commitment, and the house can’t swap the seed after seeing your bet. Once resolved, the seed is revealed — hash it, confirm it matches the commitment, and re-derive the outcome yourself on the provably-fair page.

Odds tables are versioned and immutable: a new schedule ships as a new version, never an edit to a live one, so the terms of a past pull can never be rewritten. Each box’s minimum payout is enforced at boot — the service refuses to start if any live table pays less than 2× its price.

Double-entry ledger

Balances live in an append-only ledger with two strictly separate buckets: fiat (deposited stablecoin) and credits(winnings). Every movement — deposit, box purchase, prize, inference spend — is one signed row, and a balance is just the sum of its rows. The buckets never convert into each other, and every write is idempotent (keyed on the on-chain event or request id), so a retried call or a re-scanned block can’t double-count.

Deposits & custody

Each account gets its own on-chain deposit address, derived hierarchically (BIP-32 on Base, ed25519 on Solana) from signing keys the running service never holds— it operates watch-only and cannot move a cent. A scanner credits Base arrivals past a confirmation threshold; Solana is verified at finality. Any 6-decimal USD stablecoin we accept — USDC, bridged USDbC, and USDT — is credited 1:1.

Inference gateway

Your bb-live- key authenticates against an OpenAI-compatible gateway (/v1/chat/completions, server-sent-event streaming included). Usage is metered per token at the model’s published rate and debited from your credit bucket at settlement in a single atomic step — a request can never overspend your balance or push it negative, and inference you weren’t charged for is flagged for reconciliation.
