Currently ERC-20 ecosystem is by far the biggest market for decentralised token projects and decentralised finance (DeFi). Here is a log chart of Bitcoin, Ethereum, MaidSafeCoin and a subset of the ERC20 token universe (called the Bletchley Ethereum Token Indexes BTKN). As you can see the combined market value (liquidity) of ERC-20 projects token are a large part of the overall market and as a group have been trending upwards vs ethereum market cap for some time now as new innovative projects enter, issue ERC-20 tokens and build products that create market value. The Safe Network is as innovative as they come but has a liquidity mismatch.
However non of that market capitalisation comparison and trend is as important as the network effects in play here. As the majority of decentralised projects have issued ERC-20 tokens, the infrastructure to support them is significant. Fully decentralised stable coins, dozen or so hardware wallets, hundreds of software wallets, reams of educational materials, press coverage etc . As the ERC-20 ecosystem has the biggest market of developers and investors in decentralised projects it creates a feedback loop for new projects and all that helps with attracting developer attention and investor liquidity which you can see reflected in the chart and Santiment market-cap comparison links. Lots of extra highly innovative DeFi supporting infrastructure is also available, all helping with liquidity.
Of course you can find all sorts of examples as there are all sorts of projects of varying quality including a massive rise and fall of scam projects in 2017 (ICO craze), however the overall trend of the sector is what is important as shown in previous links. To get a feel for the type of development going on here is an index to monthly lists of the most active ERC-20 project Dapps. MaidSafe should be in that list!
This is not really the correct question, or coming at it from the wrong angle. In the massive ERC-20 ecosystem Uniswap has quickly come to dominate but it is not technically a DEX, nor is it an exchange. It is more like a open permissionless nexus point for liquidity which allows “traditional” exchanges which your referring to, as well as newer DEXs, much easier to adopt ERC-20 project tokens. Think of it as an independent one stop shop for liquidity that empowers exchanges to adopt new ERC-20 token projects. It would be the only place MaidSafe would need to provide liquidity and in doing so enabling significant numbers of traditional exchanges to list the token and have instant access to the liquidity pool. I have posted a few links and scientific publications about Uniswap in last two days it is highly innovative fully recommend reading up about it.
This is exactly the sector that the Safe Network will want to make large inroads into, and attract developers and investors from. A SafeCoin(ERC-20) token is but a foot in the door.
