Metal Dollar (XMD)
You have tools to interact with XMD, XPR Network's native stablecoin. XMD is a multi-collateral stablecoin pegged to $1 USD, minted and redeemed through the xmd.treasury contract.
How XMD Works
- •Mint: Send a supported stablecoin (e.g. XUSDC) to
xmd.treasurywith memomint→ receive equivalent XMD at oracle price - •Redeem: Send XMD to
xmd.treasurywith memoredeem,SYMBOL(e.g.redeem,XUSDC) → receive equivalent stablecoin back - •1:1 peg: Oracle-priced at $1, backed by stablecoin reserves in the treasury
- •Zero fees: Currently 0% mint and redemption fees on all collateral types
Supported Collateral
| Token | Contract | Oracle Feed | Max Treasury % | Status |
|---|---|---|---|---|
| XUSDC | xtokens | USDC/USD | 60% | Mint + Redeem |
| XPAX | xtokens | PAX/USD | 15% | Mint + Redeem |
| XPYUSD | xtokens | PYUSD/USD | 15% | Mint + Redeem |
| MPD | mpd.token | MPD/USD | 2% | Mint + Redeem |
Contracts

oracles— On-chain price feeds from multiple providers
Read-Only Tools (safe, no signing)
- •
xmd_get_config— treasury config: paused state, fee account, minimum oracle price threshold - •
xmd_list_collateral— all supported collateral tokens with fees, limits, oracle prices, mint/redeem volumes - •
xmd_get_supply— XMD total circulating supply - •
xmd_get_balance— check any account's XMD balance - •
xmd_get_treasury_reserves— current stablecoin reserves backing XMD, with USD valuations and collateralization ratio - •
xmd_get_oracle_price— current oracle price for any collateral token (with individual provider data)
Write Tools (require confirmed: true)
- •
xmd_mint— mint XMD by depositing a supported stablecoin - •
xmd_redeem— redeem XMD for a supported stablecoin
Safety Rules
- •Oracle price must be >= 0.995 (
minOraclePrice) for mint/redeem to proceed - •Each collateral has a
maxTreasuryPercentcap — if the treasury already holds too much of one stablecoin, minting with it is blocked - •Check
isMintEnabled/isRedeemEnabledbefore attempting operations - •The treasury can be paused by admins (
isPaused) — check config first - •XMD has precision 6 — all amounts use 6 decimal places (e.g.
1.000000 XMD)
