ckBAT reserves Fully backed

Backed by BAT (ERC-20) held by the minter on Ethereum.
100.014%
reconciled backing
Every ckBAT is backed: net reserves are 100.014% of supply after setting aside 0 owed to withdrawals in flight. The surplus of 0.1 is fees the minter has accumulated. One native-chain source confirms the minter's figure, a second was not reachable.

A minter running low on cycles is a reserve risk too: it holds the threshold key that moves the native funds. Lifeline alerts cover both canisters, and any controller or code change on them.

How to verify this yourself

  1. Read the supply on the IC: call icrc1_total_supply on the ledger j7x7x-syaaa-aaaar-qcbea-cai (any IC client, or the dashboard link above).
  2. Read what the minter says it holds: open the minter's own dashboard at https://sv3dd-oaaaa-aaaar-qacoa-cai.raw.icp0.io/dashboard. The minter is an NNS-controlled canister; its code is public and its upgrades are voted on.
  3. Check the native chain: look up the addresses above on any explorer. The minter address holds the ETH and every ERC-20 balance; the helper contracts forward deposits to it.
  4. Subtract withdrawals in flight (burned on the IC, funds not yet final on the native chain) and compare with the supply. That is the reconciled ratio above.
