Build the receipt
into the payment.
SettleTag gives every MUSD payment an exact invoice, a one-time settlement and a public receipt. Payers settle from their wallet or borrow MUSD against their BTC through Mezo as part of the payment flow.
Invoice ledger■
Create a one-time payment reference, or load an invoice and pay it from your wallet or by borrowing MUSD against BTC on Mezo.
Find an invoice
SettleTag Pro
Standard invoices carry a 0.5% settlement fee, deducted from what the merchant receives. Pro merchants pay 0% on every invoice created while the plan is active, for 5 MUSD per 30 days. Paid to the SettleTag treasury in MUSD.
Connect a wallet to see your plan.
Trove health■
Your Mezo trove is the BTC-backed loan that can fund invoices. SettleTag reads it live from Mezo's TroveManager and price feed, and only offers borrow-to-pay while the trove stays at or above 150%.
Strengthen or repay
Adding BTC raises your ratio. Merchants can repay trove debt with the MUSD invoices bring in.
Open a trove
Lock test BTC and mint MUSD. Mezo's minimum loan is 1,800 MUSD plus a 200 MUSD gas reserve held by Mezo until the trove closes.
Test wallet■
A dedicated browser wallet for Mezo testnet. Its encrypted key stays in this browser; the password is never sent to SettleTag.
Local test wallet
Use a unique password. Save the recovery phrase before closing this page. Never send mainnet funds to this wallet.
Send
Send test BTC or MUSD to an EVM address on Mezo testnet. This signs a real testnet transaction.
Get test BTC■
Mezo's faucet dispenses test BTC. With BTC you can borrow MUSD inside SettleTag, or swap a little BTC for MUSD in the Mezo app.
Copy wallet address
Create or unlock a test wallet first.
Request test BTC
Paste the address into the official faucet and complete its CAPTCHA. Keep some test BTC for transaction fees.
Open official faucet ↗Borrow MUSD here
Open a trove on the Trove sheet, or borrow while paying an invoice. Mezo's minimum loan is 1,800 MUSD, so a new trove needs enough BTC collateral to stay at 150% or more.
Or swap a small amount
Connect a browser wallet to Mezo testnet. In the Mezo app, open Swap and choose BTC → MUSD. Review the live quote, fees, and slippage before confirming.
Open Mezo testnet ↗Read Mezo Swap guide ↗The SettleTag wallet cannot connect to Mezo Swap directly. To swap, send test BTC to an extension wallet from the Wallet sheet, swap there, then send MUSD back. Keep your recovery phrase private.
