MetaMask mUSD stablecoin goes live, offering fiat on-ramp

2025/09/16 01:03

MetaMask’s native stablecoin mUSD is live, after the initial announcement at the end of August. The asset may serve as a fiat on-ramp for one of the most widely used browser wallets. 

MetaMask announced its native stablecoin mUSD is live, after announcing the new asset at the end of August. As Cryptopolitan reported earlier, MetaMask aims to enter the $280B growing stablecoin market in partnership with Stripe. 

MetaMask’s mUSD is the first token to be issued by a self-custodial browser wallet. The asset will be fully integrated into the MetaMask ecosystem of apps, and work for swaps, on-ramps, and bridging. 

MetaMask to launch mUSD on Ethereum, Linea

The token also launched on Linea, one of the hottest new chains following the recent TGE and airdrop. The token will initially launch on Ethereum and Linea and will become a part of the Linea DeFi.

The MetaMask stablecoin follows the recent rush to create new compliant assets, based on the requirements in the US Genius Act. The stablecoin aims to tap the most active sources of liquidity in the US market.

The token will be launched by Bridge, the Stripe company for stablecoin issuance and infrastructure. It will compete with USDT and USDC, currently Ethereum’s busiest apps. The token will launch with an initial supply of around $18M. The new addition is relatively small, as the supply of stablecoins grows relentlessly to over $284.8B

Liquidity through mUSD to receive higher rewards

Immediately after the launch, mUSD started a program to become the go-to stablecoin on Linea. Currently, Linea can rely on bridged USDT and USDC, with over $304 in total supply. 

After the launch, mUSD will aim to displace that liquidity by offering bigger incentives through yield. USDT will only receive 0.1 LINEA for each $1 in liquidity, while LINEA and ETH pools will have a higher yield. 

The mUSD pools against USDT, USDC, ETH, and LINEA will start receiving rewards from September 15. For the first epoch, stablecoin pools will be assigned 2.8M LINEA, the ETH pool will receive 5.6M LINEA, and the mUSD/LINEA pair will also have 2.8M tokens set aside for incentives. 

MetaMask’s mUSD token will initially become active on the Etherex exchange, a newly launched DEX. Etherex launched in August and accrued around $180M in liquidity. The DEX carries some of the latest tokens on Ethereum, reaching $2.48B in monthly volumes. 

The DEX aims for up to $54M in annualized fees, potentially sharing them with mUSD holders as incentives and LP rewards. 

Currently, mUSD is still not distributed, with 40% of the supply held in a cluster of three wallets. On its first day of trading, mUSD achieved around $20M in volumes. Etherex is yet to gain traction on MetaMask, as Uniswap is still the leading DEX. 

The MetaMask wallet still aggregates over 85K active users for swaps, producing between $300K and $500K for fees. MetaMask swaps are relatively expensive, and mUSD aims to decrease costs and boost liquidity.

Botanix launches stBTC to deliver Bitcoin-native yield

Botanix launches stBTC to deliver Bitcoin-native yield

The post Botanix launches stBTC to deliver Bitcoin-native yield appeared on BitcoinEthereumNews.com. Botanix Labs has launched stBTC, a liquid staking token designed to turn Bitcoin into a yield-bearing asset by redistributing network gas fees directly to users. The protocol will begin yield accrual later this week, with its Genesis Vault scheduled to open on Sept. 25, capped at 50 BTC. The initiative marks one of the first attempts to generate Bitcoin-native yield without relying on inflationary token models or centralized custodians. stBTC works by allowing users to deposit Bitcoin into Botanix’s permissionless smart contract, receiving stBTC tokens that represent their share of the staking vault. As transactions occur, 50% of Botanix network gas fees, paid in BTC, flow back to stBTC holders. Over time, the value of stBTC increases relative to BTC, enabling users to redeem their original deposit plus yield. Botanix estimates early returns could reach 20–50% annually before stabilizing around 6–8%, a level similar to Ethereum staking but fully denominated in Bitcoin. Botanix says that security audits have been completed by Spearbit and Sigma Prime, and the protocol is built on the EIP-4626 vault standard, which also underpins Ethereum-based staking products. The company’s Spiderchain architecture, operated by 16 independent entities including Galaxy, Alchemy, and Fireblocks, secures the network. If adoption grows, Botanix argues the system could make Bitcoin a productive, composable asset for decentralized finance, while reinforcing network consensus. This is a developing story.
