We are a bitcoin firm by conviction, and broadly capable across chains by necessity, because clients rarely hold exactly one thing. These are real engagements, anonymized and generalized, written less as marketing than as field guides. If one of them sounds like your situation, that is because it probably is.
A Ledger Blue, formally discontinued, with a documented side-channel history and a vendor app that fought every step of a Stellar (XLM) recovery. Why "unsupported" is a spectrum, why one program at a time owns the USB interface, and why a verified negative is a deliverable worth paying for.
HARDWARE RECOVERYA dormant legacy ERC-20 BNB position whose entire market had collapsed into a single thin pool, exited without an exchange account. Quotes that were never executable, a premium that decayed as it was sold, and the tranching discipline that captured it anyway.
LIQUIDITY STRATEGYTRX in a MyEtherWallet paper wallet, untouched for eight years, issued as an ERC-20 before Tron had a blockchain of its own. Two hardware wallets ruled out address by address, the permanent cost of turning cold storage hot, and Tron's energy model that freezes an account holding real value.
CUSTODY ARCHAEOLOGYZcash stranded on a discontinued Ledger Blue with no seed backup. Recovering it meant compiling custom firmware for abandoned hardware, then finding an undocumented bug in the manufacturer's own cryptographic library that had been silently breaking Zcash signatures for years.
FIRMWARE ENGINEERINGAcross every engagement on this page, wallet interfaces, vendor quotes, and price feeds were wrong at some point, and the chain never was. That discipline, verify against the source, test what actually executes, keep custody with the client, is the product. If you have legacy assets on old hardware, a position the market has forgotten how to price, or a migration you have been putting off because the failure modes are unclear, talk to us first. Thirty minutes, no obligation, and you will leave knowing exactly where you stand.
