Unified USDC wallet — one USDC balance across chains, buy with USDC or native, sell to USDC, auto-bridge funding, native-to-USDC convert, USDC bridge.
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: Unified USDC Wallet
A GDEX user's USDC on Ethereum, Optimism, BSC, Sonic, Base, Arbitrum and Solana works as **one balance**.
Buy any token with USDC (or the chain's native token) on any of those chains; if the target chain is short,
GDEX bridges USDC in from the user's other chains automatically (`autoBridge`), never spending more than
the source budget the user signed. Sells settle back to USDC.
## When to Use
- "What's my USDC balance?" across all chains → `getUsdcBalances`
- Buying a token with USDC without first bridging by hand → `buyWithUsdc`
- Selling a token into USDC → `sellToUsdc`
- Paying with ETH/BNB/SOL but letting GDEX top up from other chains → `buyWithNative`
- Turning leftover gas tokens into USDC → `convertNativeToUsdc`
- Moving USDC between chains yourself → `estimateUsdcBridge` + `executeUsdcBridge`
## Prerequisites
- `@gemachdao/gdex-skill` installed
- Managed-custody sign-in done — see **gdex-authentication**. Every call takes
`{ apiKey, walletAddress, sessionPrivateKey }`, where `walletAddress` is the **control wallet**
used at sign-in (not the managed address).
## Automatic Funding and Gas (On by Default)

How to install
mdr add gemachdao/gdex-skill/gdex-usdc-wallet@sha256:24b7b7b7f8bed5d1The 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.
