The same defect as Cardano, in a different family, and also live. XRP fell through to wallet.ethAddress with a comment saying derivation "should be added when XRPL settlement ships" — so anyone bridging to XRP was handed an 0x string to send XRP to. XRPL's base58 alphabet is its own: `r` where Bitcoin has `1`. An address built with the standard alphabet is well-formed and names a DIFFERENT account, which is the trap — nothing rejects it, it simply points somewhere else. There is a test asserting the alphabet is XRPL's. Verified against the published genesis vector — public key 0330E7FC…FD020 encodes to rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh. That is interoperability rather than self-consistency, which is what the Cardano encoder still lacks and what its commit said to check before funds move. Also asserted: a one-character change fails the checksum, an Ed25519 key gains its 0xED prefix before hashing (hashing the bare 32 bytes gives a valid-looking address for an account nobody controls), and a key that is neither 32 nor 33 bytes is refused rather than padded into something plausible. This is the second placeholder address type found by looking. Both were comments admitting the gap next to code that shipped anyway.
bridge/server
The Lux Bridge Server is an API server that facilitates communication with Multi-Party Computation (MPC) nodes and manages asset swaps.
Prerequisites
• Node.js: Version 20 or higher.
• pnpm: Version 9.10.0 or higher.
• Docker: Ensure Docker is installed and running.
• Kubernetes: Access to a Kubernetes cluster for deployment.
Installation
1. Clone the Repository:
git clone https://github.com/luxfi/bridge.git
2. Install Dependencies:
pnpm install (from root or any project subdir)
Development
-
go into server dir
cd server -
generate prisma artifacts
pnpx prisma generate -
set up prisma to use sqlite
in
prisma/schema.prisma
datasource db {
//provider = "postgresql"
provider = "sqlite"
url = env("POSTGRES_URL")
directUrl = env("POSTGRES_URL")
}
-
set env variable to point to sqlite
in
.envPOSTGRESQL_URL=file:./dev.sqlite -
create the local
sqliteinstancepnpx prisma db push -
Start the dev server
pnpm dev
This command uses nodemon to watch for file changes and restarts the server automatically.
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): src/**/*
[nodemon] watching extensions: ts,js
[nodemon] starting `node -r tsconfig-paths/register -r ts-node/register ./src/server.ts`
>> Server is Running At: Port 5000
Building the Project
• Build the Project:
pnpm build
This command compiles TypeScript files, resolves module aliases, and generates the Prisma client.
Docker Operations
• Build Docker Image:
pnpm docker:build
This command builds the Docker image using Buildx for the linux/amd64 platform.
• Log in to GitHub Container Registry:
pnpm docker:login
Ensure that the environment variables GH_USER and GH_TOKEN are set with your GitHub username and personal access token, respectively.
• Push Docker Image:
pnpm docker:push
This command pushes the Docker image to the GitHub Container Registry.
Kubernetes Deployment
• Apply Kubernetes Configuration:
pnpm k8s:apply
This command applies the Kubernetes deployment and service configurations located in the k8s directory.
• Scale Deployment:
pnpm k8s:scale
Set the REPLICAS environment variable to the desired number of replicas before running this command.
• Create Kubernetes Secret:
pnpm k8s:create-secret
Ensure the POSTGRESQL_URL environment variable is set with your PostgreSQL connection string.
• Restart Deployment:
pnpm k8s:restart
• Check Deployment Status:
pnpm k8s:status
This command retrieves the status of deployments, services, and pods labeled app=bridge-server.
Linting and Formatting
• Lint Code:
pnpm lint
• Format Code:
pnpm format
Environment Variables
The server utilizes environment variables for configuration. Create a .env file in the server directory with the following variables:
POSTGRESQL_URL=your_postgres_connection_string GH_USER=your_github_username GH_TOKEN=your_github_token REPLICAS=number_of_replicas LUX_SIGNER=
Ensure that sensitive information is kept secure and not committed to version control.
