I’ve been trying to figure it out. When I looked through help guides and all on Binance, it kept wanting to refer me to Binance Custody whenever it referred to custodial wallets. Then once I’d click on Get Started it brought me to a sign up page where it said Please provide us with information about your business to register for Binance Custody products
Then it mentioned on another page that
Binance Chain was launched by Binance in April 2019. Its primary focus is to facilitate fast, decentralized (or non-custodial ) trading.
Sadly on that page, it never explicitly said whether Binance Smart Chain was a custodial wallet. So I kept researching and ended up at places like https://10clouds.com/blog/defi/binance-smart-chain/ and https://academy.binance.com/en/articles/the-best-crypto-wallets-for-binance-smart-chain-bsc
Most BSC wallets will be non-custodial, meaning you have control of your private key. BSC wallets are also typically hot wallets that allow you to quickly connect to DApps or start staking.
So now both chains on Binance say non-custodial. Granted, they definitely speak it to make it seem like Binance has a custodial wallet, but I can’t find it anywhere on the internet where they say their wallets are custodial. The closest I get is the quote below I found at https://academy.binance.com/en/articles/the-best-crypto-wallets-for-binance-smart-chain-bsc :
But be careful. While this is safe to do on Binance, you should not trust your funds to any custodial wallet or exchange.
So all of this is where it gets confusing. If their “custodial” wallet really is Binance Custody and it’s for businesses only according to their links, then they don’t really have custodial wallets for us. Sure, other companies have wallets available on the chain but if it’s not just strictly custodial, then there’s the issue.
I spent hours looking. While I find the occasional site that lists Binance as custodial, I can’t actually find the explicit words anyway. The closest I get is from 3rd party sites that say things like:
Centralized cryptocurrency exchanges (Coinbase, Binance, etc.) provide custodial cryptocurrency wallets (sometimes known as ‘web wallets’).
As to Coinbase, their website straight up says they are non-custodial.
Coinbase Wallet is a self-custody wallet, giving you complete control of your crypto.
But then I do also see things like quote below from https://www.makeuseof.com/custodial-vs-non-custodial-crypto-wallets/#:~:text=Some%20of%20the%20most%20popular,party%20to%20secure%20your%20funds. :
Some of the most popular crypto exchanges, such as Coinbase or Gemini, are considered custodial wallets.
