Mintr is a dApp for SNX holders
Mintr is a dApp for SNX holders to perform a variety of actions in the Synthetix Network. It provides a clean and intuitive interface that allows users to mint and burn Synths, manage their collateralisation ratio, collect fees generated by circulating Synths, send sUSD to a selling queue, view their balances and Mintr history, unlock escrowed SNX, and more.
How it Works
You can connect to Mintr using MetaMask or one of two kinds of hardware wallets: Trezor and Ledger. To use Mintr with any of these kinds of wallets, you must sign a transaction giving permission for Mintr to interact with your wallet, which you will be asked to do when connecting your wallet.

For hardware wallets that store several wallet addresses, you can choose between the addresses when you connect. Alternatively, once you have chosen a wallet address you can swap to another one from the top-right drop-down in the menu.

Minting Synths and the Collateralisation Ratio
Synthetix allows synthetic assets (Synths) to be minted against the value of SNX tokens. This is done by locking SNX into a smart contract as collateral at a ratio of 500% to the Synths minted. For example, this means that if 1000 SNX is locked at a value of $0.10 USD, 20 sUSD can be minted against it. 500% has been chosen to provide ample protection against price fluctuations.

Your Collateralisation Ratio affects the proportion you receive of fees generated by Synth transactions. If your Ratio drops below 500%, you receive fewer fees, which you can read more about here. This is to incentivise SNX holders from maintaining the entire Network Collateralisation Ratio (i.e. value of total locked SNX against value of total Synths) as well as keeping Synth prices stable.
