Hedera

Home chain

HBAR begins on Hedera. A bridge starts when coins arrive in the Hederalaunch lock account there.

That account is the reserve. wHBAR on Solana is a claim on it, unit for unit.

Reserve account

The watcher reads the Hedera record for the lock, the amount, and the consensus time.

• The account that received the HBAR.
• The amount, which becomes the credit.
• The transaction id Wormhole will sign.
• Finality on Hedera, required before a VAA is requested.

Return

A release starts as a burn of wHBAR on Solana. Wormhole carries that burn back.

Hedera then pays the same amount out of the lock. The reserve shrinks by what was released.
