ETHSP-B Primary Market
Primary market particpants are defined as any market actor directly involed in issuance, redemption, and arbitrage of ETHSP-B by interacting directly with the Portfolio Protocol.
As the secondary sub-portfolio of ETHSP, ETHSP-B offers depositors exposure to the staking rewards and relative price volatility of Coinbase Wrapped Staked ETH (cbETH) and Binance Wrapped Beacon ETH (wBETH).
Issuance and redemption features may be accessed through the Portfolio Interface (opens in a new tab). Arbitrage must be performed via direct interaction with the Portfolio Protocol.
Due to transaction costs and robust inventory requirements for participating in the primary market, explore secondary market offerings of ETHSP before attempting to interact directly with ETHSP-B.

- Unwrap the ETHSP-B ERC-20 token into an ERC-1155.
- Approve the Portfolio Protocol contract to transfer the ETHSP-B ERC-1155.
- Execute a withdraw, burning the ERC-1155. Depositor recieves a combination of cbETH and wBETH tokens.
