The locker on Stacks holds the original, and supply on Robinhood Chain matches it 1:1. No lock, no mint. No burn, no release.

What's trusted today

Custodial first. Keys come out one phase at a time.

  1. Phase 0 · now

    2-of-2 custodian

    Demo token only. Proves the asset moves end to end.

    grant requested
  2. Phase 1

    2-of-3 federation

    A signer who isn't the builder. Timeout so a lost key can't freeze the locker.

  3. Phase 2

    Bond + challenge

    A watcher can stop a bad release. Still keyed.

  4. Phase 3

    Trustless release

    Ethereum light client in Clarity checks the burn.

  5. Phase 4

    Trustless mint

    A Bitcoin relay on Ethereum checks the Stacks lock.

Don't bridge value on Phase 0. The signers hold the locker. Phase 1 is the earliest point a community token should move for real. Phase 0 is up for a Stacks Endowment grant, requested September 2026 and under review.
