Transparency
Lombard is committed to transparency. You shouldn't have to trust us, you should be able to verify everything yourself.
This section provides the information and tools to independently verify that Lombard is operating correctly: that LBTC and BTC.b are fully backed, where the smart contracts are deployed, how bridging works, and what risks exist.
Don't Trust, Verify
Lombard publishes all the information you need to verify protocol health:
Proof of Reserve. Chainlink Proof of Reserve feeds verify that LBTC and BTC.b are fully backed by Bitcoin. These feeds update every 10 minutes, and anyone can check them on-chain.
On-chain records. Every Consortium authorization is recorded on the Lombard Ledger. Mints, burns, and cross-chain transfers all leave verifiable audit trails.
Published contracts. All smart contract addresses are public. You can verify you're interacting with official Lombard contracts, review the code, and check audit reports.
Open documentation. This documentation exists so you understand exactly how the protocol works, no black boxes.
What You Can Verify
LBTC Backing
Every LBTC is backed by BTC staked through Babylon. You can verify:
Total BTC held in Lombard's Bitcoin addresses
Total LBTC supply across all chains
That backing ratio is maintained (BTC ≥ LBTC)
BTC.b Backing
Every BTC.b is backed 1:1 by native Bitcoin held in reserve. You can verify:
Total BTC held in BTC.b reserve addresses
Total BTC.b supply
That the 1:1 ratio is maintained
Exchange Rate
The LBTC/BTC exchange rate increases over time as staking yield accrues. You can verify:
Current exchange rate on-chain
Historical rate changes
That the rate only increases (never decreases)
Contract Authenticity
Before interacting with Lombard, you can verify you're using official contracts:
Check contract addresses against our published list
Review verified source code on block explorers
Confirm contracts match audited versions
