Cross-chain bridging — get estimates and execute native token transfers between EVM chains, Solana, and Sui via ChangeNow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GDEX: Cross-Chain Bridge
Bridge **native tokens** between supported chains with quote previews and time estimates.
Uses ChangeNow as the bridge provider (StarGate support exists but is currently disabled).
> **Moving USDC?** The unified USDC wallet has its own capped USDC bridge (`estimateUsdcBridge` / `executeUsdcBridge`) and trades can auto-bridge USDC for you. See **gdex-usdc-wallet**.
## When to Use
- Moving native tokens from one chain to another (e.g., ETH on Ethereum → ETH on Base)
- Getting a bridge estimate before executing
- Checking bridge order history
## Prerequisites
- `@gemachdao/gdex-skill` installed
- Authenticated via managed-custody sign-in — see **gdex-authentication**
- Session keypair (sessionPrivateKey + sessionKey) from sign-in flow
## Backend Endpoints

How to install
mdr add gemachdao/gdex-skill/gdex-bridge@sha256:5c10d9a460e6e820The line at the top of this page pins the label git:20261019.143efdd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
