About
What it answers, and for whom.
LBTC is Lombard's yield-bearing bitcoin token: BTC deposited with Lombard is staked through Babylon, and LBTC, minted one for one at deposit, gains value in BTC as staking rewards are added to its exchange rate. This dashboard reads LBTC's supply on every chain it is issued on and sets it against the bitcoin Lombard holds on Bitcoin and the part of it staked through Babylon.
The bitcoin is controlled by Lombard's Security Consortium, a group of institutions that jointly approve deposits, mints and redemptions and hold the keys through threshold signing. That is a different trust model from a single custodian's, and the dashboard shows what can be checked about it on-chain: the BTC in Lombard's published addresses, the staking outputs that delegate it and the mints that match each deposit.
LBTC moves between chains by burning on one and minting on another, so supply on each chain adds up without counting a coin twice. BTC.b, the bitcoin token Lombard took over from Avalanche's bridge, earns no yield and is shown on its own line. Every figure names its block and read.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- LBTC supply is totalSupply on each chain at its day-end block; cross-chain transfers burn on one chain and mint on the other, so the chains add up, and each transfer is matched to its message.
- Reserves are the balances of the Bitcoin addresses Lombard publishes for deposits and staking, read from the UTXO set at the latest block.
- Babylon stake is the value of active staking outputs whose finality provider is Lombard's, found by parsing staking transactions on Bitcoin.
- The exchange rate is read from LBTC's rate source on Ethereum at each day's last block, and each update is recorded.
- Where LBTC is used comes from the balances of known lending markets, DEX pools and vaults on each chain.

Questions
Questions people ask.
What is LBTC?
LBTC is Lombard's yield-bearing bitcoin token. BTC deposited with Lombard is staked through Babylon, and LBTC gains value in BTC through its exchange rate as staking rewards are added. It is issued on several chains and moves between them by burning and minting.
Who holds the bitcoin behind LBTC?
Lombard's Security Consortium, a group of institutions that jointly approve deposits, mints and redemptions and control the Bitcoin keys through threshold signing. The bitcoin sits in outputs on Bitcoin, which the dashboard reads directly.
How is LBTC different from WBTC or cbBTC?
WBTC and cbBTC are custodial tokens whose bitcoin earns nothing. LBTC's bitcoin is staked through Babylon, so the token earns staking rewards, and custody is shared by a consortium rather than held by one firm. Each model rests on different trust assumptions.
What is BTC.b?
A bitcoin token first issued by Avalanche's bridge and taken over by Lombard in 2025. Unlike LBTC it earns no yield. The dashboard keeps its supply apart from LBTC so the two are never added together.
How long does it take to redeem LBTC for BTC?
A redemption burns LBTC and asks the consortium to release BTC on Bitcoin. Because most of that BTC is staked, it may first have to wait out Babylon's unbonding period. The dashboard shows redemptions requested and paid each day.
- Security Consortium
- The group of institutions that approves Lombard's deposits, mints, redemptions and transfers and jointly controls its Bitcoin keys.
- Finality provider
- An operator that signs blocks on Babylon's chain and receives BTC delegations; Lombard delegates its staked BTC to its own.
- Burn and mint
- A cross-chain transfer that destroys tokens on the source chain and creates them on the destination, so total supply stays the same.
- Yield-bearing token
- A token whose balance stays fixed while its exchange rate rises, so its holder's claim on the underlying asset grows.
