@paradoxcomputer/lpad-linux-x64

The Linux x86_64 build of the lpad CLI - a bonding-curve + LBP token launchpad for the Logos Execution Zone.

Do not install this package directly. Install @paradoxcomputer/lpad instead; it lists this package as an optional dependency and npm picks the right one for your machine from the os/cpu fields. This package contains no launcher and puts nothing on your PATH.

Requirements

• Linux, x86_64
• glibc >= 2.34 (Ubuntu 22.04+, Debian 12+, Fedora 35+, RHEL 9+). The binary is built against that floor; on anything older the loader refuses it with a GLIBC_2.34 not found error. musl systems (Alpine) are not supported by this package - build from source there.

Why libpcsclite is in here

ldd bin/lpad lists exactly libpcsclite.so.1, libgcc_s.so.1, libm.so.6 and libc.so.6. The last three are on every glibc system; libpcsclite is not. It is a link-time dependency of the upstream LEZ wallet crate, which pulls in Keycard smartcard support unconditionally with no feature gate. lpad never touches a card reader, so the library is dead weight at runtime - but the loader still has to find it, and requiring apt install libpcsclite1 before npm i -g works would defeat the point of shipping on npm.

So the library ships here, and the @paradoxcomputer/lpad launcher prepends this package's lib/ to LD_LIBRARY_PATH for the child process only.

It is BSD-3-clause (plus ISC for one file); redistribution requires the attribution in lib/LICENSE-libpcsclite.txt, which is why that file ships too.

The binary is not in git

bin/lpad and lib/libpcsclite.so.1 are build outputs, not source, so they are .gitignored in the repository. They are filled in immediately before publishing - by the release job for a real release, or by npm/scripts/assemble-linux-x64.sh when testing locally. A checkout of this directory therefore looks empty; see npm/README.md in the repository for how the whole thing fits together.

Licence

lpad is dual-licensed MIT OR Apache-2.0 (LICENSE-MIT, LICENSE-APACHE). The bundled libpcsclite is covered separately by lib/LICENSE-libpcsclite.txt.
