Bullion Integrity Ledger™

BIL Infographic.png

The Bullion Integrity Ledger™ is a neutral product platform that connects all stakeholders of the global precious metal industry. It is a decentralised, secure and member-based platform for peer-to-peer interaction.

As stakeholders along the global value-chain of precious metals have specialised in different core competencies, aXedras focuses equally on their diverse business requirements. Our product offering is designed modularly in order to satisfy these diverse requirements. The Bullion Integrity Ledger™ utilises the same, mutually agreed on data standard.


In order to digitalise B2B processes, the Bullion Integrity Ledger™ enables its members to share information following this unified data standard and to record the outcomes of business transactions in an immutable and auditable manner. Ultimately, this leads to properly documented products without compromising the confidentiality of the owners or the parties otherwise involved in the transactions.
