The one rule

Three cards in.
One rarer card out.

Pick any 3 cards of the same tier. Fuse them. They are burned forever, and you get 1 card of the next tier that plays all three notes as a chord.

3 → 1

Fusion is open to anyone holding cards, agent or not. No luck involved: the result is always the next tier.

Claim

Let your agent mint it.

Minting is reserved for Binance Agentic Wallets holding an Agent ID (.ai). The contract checks it on-chain. Free cards are sold out. Up to 10 paid per wallet at $0.60.

1

Check your wallet

Paste your Agentic Wallet address. We read the chain to see if it holds an Agent ID and what it can still mint.

2

Hand the prompt to your agent

Your agent fetches the ready-made transaction and runs it with the baw CLI. No forms, no posts, no voucher.

3

Reveal and listen

Come back, flip your card and hear its note. Then start collecting threes.

Anatomy
Read a card in 5 seconds.
Everything on a card comes from its on-chain seed. Nothing is rolled off-chain.

    Rarity

    Note or chord
    A Tone sings one note. A fused card keeps the three notes of the cards that made it.

    Wave
    Sine, triangle, square or saw. It shapes how the card actually sounds when you tap it.

The owner can only open or close the mint, update the metadata link and withdraw. Prices, supply and limits cannot be changed.

FAQ
Questions

    

      
I don't have an Agentic Wallet. Can I join?
You can't mint, but you can buy cards on Element, keep them, trade them and fuse them right here in My Deck with any wallet.

      
How do I get an Agent ID?
Open the Binance Wallet app, set up an Agentic Wallet and claim your .ai Agent ID from the banner. Your agent can check with baw wallet agent-id.

      
How many Tones make a Sonic Boom?
27. Three Tones make a Chord, three Chords make a Harmony, three Harmonies make a Sonic Boom. One Agent ID can mint 11 cards at most, so a Sonic Boom always takes trading or teamwork.

      
Is the art on-chain?
Traits, seeds and fusion history are on-chain. The card images are rendered from that data by our open server code and served from sonicprotocol.fun.

      
Why can't I hear anything?
Phones block sound until you tap. Tap a card once, and check your silent switch.
