Bylines, paper authorship, correspondence addresses and the founder blurb under each post named an individual. They name the organisation that published the work instead: the brand on posts and pages, the research byline on papers, and research@ in place of a personal address. Both are what these repositories already used elsewhere — nothing new was coined. Co-authors are untouched. Where a paper named someone else alongside, they stay named; only the one byline changed. Bibliography entries, running heads, PDF metadata and affiliations move with it, so a citation still resolves to whoever the cited paper names. Sample and fixture data uses the placeholder name these tests already use elsewhere, so no assertion changed meaning.

\begin{abstract}
|

We describe the engineering architecture of Lux Teleport, a universal cross-chain bridge serving 270+ chains through a single protocol binary. The design separates concerns into four layers: (1)~a \emph{frozen wire protocol} comprising four canonical proof tags---\texttt{DEPOSIT}, \texttt{YIELD}, \texttt{BACKING}, \texttt{RELEASE}---encoded as \texttt{bytes32}-tagged \texttt{abi.encode} payloads with MPC-signed proofs, per-\texttt{srcChainId} replay protection, and monotonic backing attestations with configurable staleness windows; (2)~a \emph{chain-agnostic Teleporter contract} that implements the wire protocol against an abstract chain adapter interface, enabling a single audited contract to serve all EVM deployments; (3)~a \emph{pluggable chain adapter} layer supporting four support classes---Lux-native (Warp, no MPC hop), external EVM (\texttt{TeleportVault} template), Bitcoin-family script chains (watcher-first: OP\_NET, Litecoin, Dogecoin), and non-EVM account-model chains (Solana Ed25519, TON Ed25519, XRP secp256k1); and (4)~a \emph{multi-tenant architecture} where hostname-based routing, per-tenant manifests, and shared MPC infrastructure enable white-label bridge deployments from a single binary. We specify the threshold signing interface unifying CGGMP21 (ECDSA/secp256k1 for EVM), FROST (Schnorr for Bitcoin Taproot), and BLS (Lux Warp internal) under \texttt{github.com/luxfi/crypto/threshold}. We formalize the security model including per-chain confirmation depths, backing attestation monotonicity, sequential withdraw nonces, peg oracle auto-pause thresholds, and hot wallet / MPC key separation. We describe the yield composition pipeline through which bridged assets earn layered returns via Babylon staking, D-Chain LP, and bridge fees through the xLUX instrument. Finally, we specify the 6-artifact conformance testing framework that gates chain onboarding through CI/CD.
