# Trustless Relayer

Lombard operates several non-critical APIs and services to aid in communication between blockchain networks and enhance the user experience.

These APIs have limited elevated privileges (Operator and Claimer roles, see [lbtc-design](https://lombard.gitbook.io/lombard/technical-documentation/protocol-architecture/lbtc-design "mention")), as well as permission to submit transactions on the Lombard Ledger.

1. Monitor the Bitcoin network, and report any suspected Lombard Protocol related deposits to Lombard Ledger.
2. Monitor [supported-blockchains](https://lombard.gitbook.io/lombard/technical-documentation/supported-blockchains "mention") and report any CCIP bridge events to Lombard Ledger.
3. Monitor Lombard Ledger, and automatically mint LBTC for depositors, after authorization from Security Consortium.
   1. *Note: After Consortium authorization, a user can always mint their own LBTC, e.g. in the instance when auto-mint is disabled due to a period with high transaction costs.*
4. Record all Lombard Protocol related Bitcoin deposit addresses on an on-chain registry (on Base), used for Proof-of-Reserve attestation validation.
5. Request on Lombard Ledger to (un)stake into Babylon. *This is temporary, until automation on Lombard Ledger in a future upgrade.*
6. Monitor the performance of Lombard Ledger and the LBTC ecosystem.
