However, given the recent events (FTX, Silvergate Bank, etc), the custodial risk that comes with using centralized services far outweighs the benefits. There are very talented teams that have created user-friendly wallets (Rainbow, Uniswap, etc) to help users interact with DeFi and invest in a non-custodial way. And with the addition of TWAMMs in the backend, the products and service offerings can be vastly improved. {% embed url="" %} ### Whales & Minnows DCA DCA is a high-value add functionality because it allows retail investors to take a position without having to time the market. It's also a great source of non-toxic order flow that liquidity providers would love to have. Additionally, when this can be done non-custodially and on-chain, this becomes a killer feature for wallets to leverage TWAMMs for. {% embed url="" %} When taking a large position, timing the market is very risky and it's prudent to gradually fill your order. Unfortunately, everything available on-chain today completes your order in a single block unless you're sophisticated enough to set and withdraw your out-of-range Uniswap V3 position. {% embed url="" %} Soon, the reason to use CEX will be simply to on-ramp into crypto. TWAMMs will unlock passive traders' ability to invest in the market while not taking custodial risk. Additionally, it will increase the amount of active capital deployed on-chain, thus growing the pie for all other protocols as well. ### Future Vision Centralized exchanges are already aware of this trend and the forward-thinking ones are positioned to be the customer relationship owners. Coinbase recently introduced their Wallet as a Service which makes it easier to onboard CEX users directly into DeFi protocols front-ends. {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.
