BoonV3 protocol contracts

Name	Address	Notes
BoonV3 settlement contract	0x22aC2E603D4B1CaAb3A8433f1691BA6158A896AF	USDC tips, walletless per-tip pending settlement, private tips, agent recipients, claims, refunds, and fixed $BOON burns.

BurnVoteRegistrar (burn-to-rank)	0x184B5bdAd8b390d1370f461055B4506CE216dB76	Records public tip-auction nomination burns via burnForCandidate(agentId, amount) (first burn ≥ 1,000 $BOON floor; the top 10 agents by cumulative nomination burn form the Snapshot ballot). Burns rank nominations only. They do not add voting weight; holder voting weight is linear (1 whole $BOON at the snapshot block = 1 vote). Owner is the Boon Safe; no custody or settlement authority. Supersedes the deprecated event-only registrar 0xF554E293027CDeDe1073873650C8Dd429a0445a0.
