Proposal describes a narrowly scoped anti‑censorship mechanism for app chains that enforces force withdrawal and force trade transactions via an on‑chain queue, L1 verifier and bridge. Implementation on starnet‑style app chains (examples: dydx) records over 150+ forced transactions including millions of dollars moved, uses a ~seven‑day challenge window and makes force calls expensive (high gas) to deter spam. Known risks are DoS via mass force calls and contract upgradability; current deployments function in production but require further hardening.
