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).
## 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
| Method | Path | Purpose |
|--------|------|---------|
| `GET` | `/v1/bridge/estimate_bridge` | Get a bridge quote |
| `POST` | `/v1/bridge/request_bridge` | Execute a bridge (encrypted) |
| `GET` | `/v1/bridge/bridge_orders` | List bridge order history |
## 1. Get a Bridge Estimate (Quote)
```typescript
import { GdexSkill, GDEX_API_KEY_PRIMARY } from '@gemachdao/gdex-skill';
const skill = new GdexSkill();
skill.loginWithApiKey(GDEX_API_KEY_PRIMARY);
const estimate = await skill.estimateBridge({
fromChainId: 1, // Ethereum
toChainId: 8453, // Base

How to install
mdr add gemachdao/gdex-skill/gdex-bridge@sha256:c3de73ede59efa6eThe line at the top of this page pins the label git:20261015.073f01e, 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.
