The product layer for Bitcoin in banking.
Infrastructure enabling regulated banks to offer Bitcoin-backed financial products — natively, non-custodial, on Bitcoin L1.
Bitcoin is on bank balance sheets. But stored value without utility is a missed opportunity — for banks and their clients alike. The infrastructure to activate it simply does not exist at the institutional layer.
Bitcoin will become the foundational collateral layer of institutional finance. Not as a speculative asset — as infrastructure. The banks that build this capability early will define the next generation of wealth management.
trailz is the middleware that makes it possible. A turnkey product layer enabling Bitcoin-backed lending and structured products — without custody, without bespoke development, without compromise on compliance.
