How BNB reaches Canton
Three moves, one to one. Your BNB never leaves BNB Chain.
-
01 LockBNB
Your BNB goes into an on-chain contract on BNB Chain and stays there, in the open, for as long as the CBNB exists.

02 Verify
Nuxaris
The lock is confirmed, then a signed attestation crosses to Canton. The message crosses; the asset does not.

The promise
One BNB behind every CBNB. No exceptions, no fractions.
The BNB sits in a contract on BNB Chain. It is released the moment the matching CBNB comes back, and nothing is ever issued before it arrives.
-
1:1
Fully backed
One BNB is held on BNB Chain for every CBNB in circulation. No fractional reserve, ever.
-
Non-custodial
Never held for you
Your BNB sits in a contract, not on a desk. Nothing takes ownership of it while the CBNB exists.
-
Standard
Works out of the box
cBNB follows the Canton Token Standard, so any wallet or application that supports it can hold and settle cBNB.
