Nacre is a 1:1-backed bridge that brings native PRL from the Pearl L1 onto Solana as the SPL token wPRL. Lock PRL on Pearl, mint wPRL on Solana, use it anywhere SPL tokens are accepted — DEXes, lending, payments — then burn wPRL to redeem PRL back on Pearl.

What is wPRL?

Token info, contract addresses, fees, transferability.

Mint wPRL

Walk through depositing PRL and receiving wPRL.

Burn wPRL

Redeem wPRL back to PRL on Pearl.

Recover unprocessed PRL

Got stuck? Pull your PRL back via the emergency exit.

​
Why Nacre

  • 1:1 backed. Every wPRL is backed by exactly one PRL held in Pearl reserves.
  • No custodial admin on the hot path. A 3-of-4 validator quorum signs every mint and burn. Validators are independent and run their own Pearl and Solana nodes.
  • User-controlled emergency exit. If something goes wrong, a 7-day script-path on the Hot Reserve lets you reclaim your PRL without anyone else’s signature.
  • A clear path to trust minimization. v1 ships with a custodial signer; the roadmap lays out the migration to FROST self-custody, TEE-attested validators, and ultimately ZK validation.

Independent validators observe both chains, propose deterministic actions, and a quorum threshold of signatures unlocks PRL or mints/burns wPRL. See Architecture.

Status

Nacre is in active development. Contract addresses, validator set, and deployment targets are marked TBD throughout these docs and will be filled in at launch.
