I wondered the same thing when I first used Trust Wallet a year ago to stake. Instead of investigating deeply I decided to move away from Binance products like TW and use Solflare to stake. Phantom is another good option as well. I use Stakeview.app to check out top paying validators and spread across those.
TW has had too many issues over the past few years and is controlled by highly centralized entity so made sense in the spirit of blockchain to move away.
Whew glad none of my stake is adding to this list.
If you stake in Solflare wallet, they just added a feature to instant unstake (for a small fee of course).
Coinbase also doesn’t offer any option to choose your validator which means you’re forced to use Coinbase as your validator. Currently they’re offering a 5.01% APY but some of the top validators offer over 8%.
Never EVER interact with any contracts with your wallet that is staking SOL. Setup a stake wallet, write down the seed and delete the wallet from your phone. Create a new wallet just for interacting with contracts, deposit a small amount of SOL. 98% of risk is mitigated with this strategy
Use Stakeview.app to browse through validators. The top ones are always changing but usually within a few hundredths of a percent from each other. I use Stakehaus, Chive and Blocksmith as my top APY validators.
