Smart Contracts

This page lists all official Lombard smart contract addresses across supported chains. Always verify you're interacting with these addresses, do not trust links from unofficial sources.

How to Verify

Before interacting with any contract:

1. Check this page for the official address

2. Verify on the block explorer that the contract is verified and matches the address here

3. Bookmark the official app at app.lombard.finance — don't use links from search results or messages

If an address doesn't match what's listed here, do not interact with it.

Contract Types

There are three types of contracts deployed on networks where LBTC is supported:

LBTC/BTC.b token contracts: Mint and burn tokens.

Consortium's governance contract: Reads and commits state changes related to LBTC, ensuring all actions are transparent and verifiable on-chain.

Proxy upgrade timelock contract: Delays proxy upgrades by one hour, providing additional security to detect and cancel malicious upgrades.
