## Research summary

We reject the bridge balance as a client position after an adverse research review. The worklist entry measures assets locked for an OP Stack rollup, not a yield product. Fraxtal currently depends on a permissioned sequencer, upgradeable Ethereum bridge proxies, a Frax-team data-availability module, and a seven-day ordinary L2 withdrawal. Official materials describe future validator security, not a live permissionless replacement. A separate chain grade must first prove an enforceable exit window and set limits on emergency authority.

## Observable review triggers

- Fraxtal receives a sourced Ketju chain grade with no active rejection criterion
- Permissionless fault proofs and forced inclusion are live and a proposed-size Ethereum exit completes without sequencer cooperation
- Every regular upgrade has an enforceable on-chain delay of at least 7 days and emergency authority is independently bounded
- The production data-availability mechanism and recovery path become independently verifiable
