Breakseat

For card-break hosts and buyers

Deal break teams fairly, then let anyone check the deal.

List the seats of your break, lock the team draw to a Solana block that has not happened yet, and share one link. Anyone can open it, re-run the shuffle and get the exact same result.

The shuffle seed is that block's block hash, read live from Solana mainnet. Free to use, no sign-up, no money involved.

How it works in three steps

  1. IFill the seatsType the buyers' names or paste your team list.
  2. IILock a future blockThe draw waits for a Solana block nobody can predict.
  3. IIIShare the result linkAnyone re-runs it and sees the same teams per seat.

Nothing is bought, sold or charged here. Your wallet is only used if you choose to post an optional on-chain note.

The house rules, in four moves

Why nobody can rig the deal

  1. 01
    Seats are written down first

    The seat list and team list are turned into a short fingerprint. Change one letter and the fingerprint changes.

  2. 02
    A future block is chosen

    You pick a slot that has not happened yet, so its hash is unknown to everyone, including you.

  3. 03
    The block lands, the deck is cut

    Its block hash plus the fingerprint become the shuffle seed. The same seed always gives the same shuffle.

  4. 04
    Teams go round the table

    Teams are dealt one at a time, seat 1 to the last seat. Anyone with the link can redo every step.

      Plain words

      The few terms this page uses

      Card break
      A group opening of sealed card products, where each buyer owns a seat and gets the cards of the teams dealt to that seat.
      Slot
      Solana's clock tick, about 0.4 seconds. Each slot can hold one block; a few are skipped, and then the next made block is used.
      Block hash
      The code a block gets when it is made. It is public and cannot be guessed in advance.
      Fingerprint
      A SHA-256 summary of the break name, seats, teams and slot. Any edit gives a different fingerprint.
      Seed and shuffle
      The seed is SHA-256 of the block hash plus the fingerprint. It drives a standard Fisher-Yates shuffle with no bias.
      Memo
      A short text note saved on Solana in a normal transaction. Here it can record a lock before the block exists. Costs about 0.000005 SOL.
      Wallet signature
      Your wallet approving one exact action. This site never asks for your recovery phrase.
      CA (contract address)
      The address of a coin on Solana, used to look it up. Ours shows here only once a coin exists.

      Questions at the table

      FAQ

      What is this, in one sentence?

      A free page that splits a card break into seats and deals the teams with a shuffle seeded by a future Solana block, so anyone can check the deal was fair.

      Is it safe? Does it touch my money?

      It never touches money. Connecting a wallet only shares your public address. The one optional transaction is a memo note you approve in your own wallet, which costs only Solana's network fee of about 0.000005 SOL and sends nothing to anyone.

      Could the host pick a block that suits them?

      Not if the lock was shared before the block was made. That is why the draw only accepts a slot in the future, and why posting the lock as a memo (or sharing the board link early) matters: it proves the list and slot were fixed first.

      What if the chosen slot has no block?

      Some slots are skipped by the network. The rule is simple and public: use the first block made at or after the chosen slot. The result link shows which slot was actually used.

      Where are my seat lists stored?

      Only in your browser and inside the links you copy. There is no account and no server-side database.

      Does this sell cards or run paid breaks?

      No. It is a fairness tool. Payment for a break happens wherever the host sells it, never here.
