Uni is going to restart liquidity mining on April 15th, which involves 12 pools, many of which are related to USDT0. So, taking this opportunity, let me talk about USDT0. Firstly, what is USDT0? Simply put, it is the cross chain version of USDT, where the parent asset USDT is stored on ETH, and it becomes USDT0 by crossing the chain to other chains through Layer0. Supporting USDT0 can also cross over, such as ETH Arb Unichain Bear Chain MegaETH, and so on. Who is the team behind USDT0? This is the most Tricky, and it took me a long time to figure it out. The USDT0 project is a joint effort of 1+3 companies: 1. Led by Everdown Labs; 2.1 The underlying technology used is Layer0; 2.2 Received endorsement from Tether; 2.3 has received endorsement from the INK public chain (which is a chain issued by Kraken). However, there is no clue on the internet who Everdown Labs really is. I have a reasonable suspicion that it is Tether's vest. This is quite in line with their tone: If nothing goes wrong - then everyone can enjoy the convenience of USDT's multi chain as usual; If something happens - it's Everdown Labs' fault, not Tether's. One of the reasons for this speculation is that after the release of USDT0 this year, Tether officials immediately expressed support, and Bitfinex subsequently issued a special article to interpret it. If there is no strong relationship, they (BF and Tether) will not provide such support. How to evaluate? I think if Tether were to personally build this bridge, it would definitely be a great achievement. This would allow USDT chains to cross each other without any damage, saving them from having to walk through various sand carved three-way cross chain bridges. However, my level of trust in Layer0 is limited. There have been numerous cases of top-level cross chain bridges collapsing in the past, from multichain to Thorchain. Cross chain technology has no threshold at all, it's just about signing multiple contracts. In the past, USDT used to use the official bridge instead of the L0 three-way bridge. Official bridges are generally safer, but the downside is dispersed liquidity. For example, if you want a large amount of funds to cross OP from Arb without loss, you must return ETH from Arb before going to OP, and if you go through three parties faster, you will have to spend money. PS： Not to mention Sei, who is a deceitful public chain that charges fees for entering and exiting official bridges. If we follow the USDT0 plan, Arb can directly go to OP without loss and in seconds. PS： Of course, there is still a historical legacy issue with OP, which is that USDT on OP is the old version of ETH cross chain version, and it has not been unified with USDT0, the youth version of ETH cross chain version. Therefore, Arb cross OP is nominally feasible, but in reality it was not useful in the past. Here is just an example. And the new public chain, because it supports USDT0 from the beginning and has no historical legacy issues, has much higher availability. But! Tether officials themselves are reluctant to personally step down to build this bridge and insist on sending an Everdown Labs to cover up, which is a bit 😂 In the past, when I mined UNI on ETH, I only had to bear two small third-party risks, Tether and Uniswap. Now, I have to bear an additional four risks, namely: Everdawn, don't make a mistake L0, don't make mistakes Unichain, don't mess up USDT0 supports N other public chains, each one should not make mistakes If other public chains are hacked and USDT0 is infinitely increased, then other chains' USDT0 will also be contaminated It sounds a bit big headed 🤦。
