Smart Contract Upgrade: More Flexible Subscriptions & Redemptions

The newest version of Superstate’s token smart contracts, SuperstateTokenV5, is live on Ethereum Mainnet. The upgrade adds useful functionality and will be used for EVM deployments going forward.

Subscribe function

The main change is the addition of another subscribe function with a to argument to the token contract. This allows investors to specify which Allowlist address belonging to their entity should receive USTB while using Protocol Subscriptions. Similarly, another redeem function that takes a to argument was added to the Redemption contract. It allows investors to specify any Ethereum Address to send USDC to after redeeming USTB.

1. Now emits the to argument
