CRIT: neuter the forgeable Verkle stub at 0x0300..20; gate all quasar precompiles under StrictPQ
The verklePrecompile.Run shipped to C-Chain + Partner EVM (both
import luxfi/precompile/quasar) called verifyVerkleLight which
accepted any (commitment, proof) where the first 17 bytes matched:
for i := 0; i < len(commitment) && i < len(proof); i++ {
if commitment[i] != proof[i] {
return i > 16 // 'At least half match'
}
}
A caller submitting commitment=zeros, proof=zeros, threshold_met=1
got back []byte{1} from a precompile registered at the canonical
0x0300...0020 'Verkle verify' slot. Any EVM-side contract that
trusted that response to gate fund transfers was a forge-and-drain
target.
Fix is surgical: every quasar Run now starts with:
if err := contract.RefuseUnderStrictPQ(accessibleState); err != nil {
return nil, suppliedGas, err
}
PLUS verklePrecompile.Run is rewritten to always return
ErrQuasarPrecompileDeprecated. The other 5 (bls, bls-aggregate,
corona, hybrid, compressed) keep their bodies but are now StrictPQ-
gated.
The canonical PQ verifiers live in the LP-4200 0x012200 block
(0x012201 ML-KEM through 0x012206 Corona). Callers should route
there. quasar/ stays for slot-reservation only.
contract_test.go + deep_test.go deleted — they pinned the old
forgeable behavior, asserting Run returned []byte{1} for matching
bytes. Replaced with a single sentinel test that the deprecated
error symbol exists.
