§1The leak

Your address is an open diary.

Every mint, every airdrop claim and every token-gated sign-in points back to one address. Together they spell out your holdings, your cost basis and your habits, in a public record anyone can read for as long as the chain exists.

  • Nobody copies your trades the moment you make them
  • Give out an address without giving away your PnL
  • Show you’re solvent without opening your books
§2The kit

The bond stays sealed. Only the proof goes out.

2.1

Seal

Lock an asset into a bond under a one-time key. It joins the shielded set with nothing publicly tying it to your wallet.

2.2

Receive

Receive bonds straight into the shielded set, not into a wallet the whole world is watching.

2.3

Transfer

Hand a bond over with a key that has never signed anything else. The old bond is retired the moment it leaves.

2.4

Prove

Open one bond to one counterparty. Nothing else is shown and nobody else is named.

§3The method

Three steps between what you own and the public record.

01

Seal

Your browser hashes the asset together with a secret salt and a new key. The chain receives a single 32-byte value.

02

Hold

Holding, receiving and transferring are all updates to the set. Anyone watching can see that something changed, never what.

03

Prove

A verifier checks your bond against the live state of the chain and gets one bit back: yes or no.

§4$TACIT

Every action costs a little $TACIT.

Each bond action pays a small fee in $TACIT, so using the protocol uses up the token. The more people use it, the less $TACIT there is.

4.1

Action fees

Sealing, transferring and proving each pay a fee in $TACIT. No fee, no bond.

4.2

Burned on settlement

80% of every fee is burned when the action settles. The other 20% pays the provers who keep the pool running.

4.3

Holder slots

Holding $TACIT gives you more bond slots and unlocks batch proofs. Your tier is private too.

Sealing, transfers and receipt checks already work in the console. Onchain settlement arrives with the engine, on this contract.

Connecting a wallet gives away a hundred answers nobody asked for. Tacit gives exactly one.

Robinhood Chain

Keep it quiet.

Seal an asset into a bond, keep it under a key that has never touched anything else, and prove you hold it whenever someone asks. The rest of your portfolio stays out of it.
