Right now the collateral is primarily BYUSD (bridged Paypal USD). If someone is looking to redeem this, they could either bridge to Eth and swap it on the Curve pool, or send it to Coinbase/OKX/Bybit/Crypto.com/Kraken to offramp directly.
We'll be doing our best to make this easier from Berachain in the future, but until then, we'll focus on being pro-active on messaging. If anyone needs help, please feel free to reach out to myself, or our team via DMs.
