Seed-deposit requirement for new market listing
Cap (cUSD / stcUSD)'s assessment for RD-F-071 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Cap explicitly seeds the stcUSD ERC-4626 vault with 1 wei at deployment. This is acknowledged in the Sherlock audit README as a known design choice: 'the last withdraw can revert since we can get 1 wei less funds back. We will seed the vault with 1 wei to offset this.' The 1-wei dead-shares mechanism prevents first-depositor rounding attacks and is equivalent to a minimum seed deposit. No market-listing governance exists (operators are whitelisted; no permissionless market creation), so the standard lending seed-deposit probe does not apply in its original sense.
