A July commit removed eight papers on the premise "no license — DEX/non-custodial only". That premise is wrong: Lux operates an ATS, a broker-dealer, a transfer agent and a bank, and this material is resold at lux.financial. The merge that brought main in preserved the removal because the commit stated a reason, which is how a stale reason outlives the fact it rested on. Back, at the versions main carried — main never received the removal, so its copies are the later ones: the ATS architecture, the security-token standard, smart order routing, institutional custody, MPC custody, post-quantum securities, the SSB partnership and the CoinBridge brief. 83 files.

\section{Integration with EVM Precompiles}

\label{sec:precompiles}

%% =====================================================================
|
|
|
|
A regulated EVM L1 includes native precompiles for the cryptographic
|
|
primitives used in threshold signing:

\begin{table}[h]

\centering
|
|
\begin{tabular}{llr}
|
|
\toprule
|
|
\textbf{Precompile} & \textbf{Operation} & \textbf{Gas} \\
|
|
\midrule
|
|
FROST (\texttt{0x0300...0005}) & Verify Schnorr signature & 3,000 \\
|
|
SR25519 (\texttt{0x0300...0001}) & Verify SR25519 signature & 3,000 \\
|
|
Ed25519 (\texttt{0x0300...0002}) & Verify Ed25519 signature & 3,000 \\
|
|
CGGMP21 (\texttt{0x0300...0006}) & Verify threshold ECDSA & 3,000 \\
|
|
secp256r1 (\texttt{0x0300...0003}) & Verify P-256 signature & 3,500 \\

\end{table}
|
|
|
|
These precompiles enable on-chain verification of threshold signatures
|
|
at the same gas cost as standard ECDSA verification. Smart contracts
|
|
can verify that a settlement transaction was properly authorized by
|
|
the threshold scheme without needing to implement the verification
|
|
logic in Solidity.
