What changed

Repo	Files	Change
vips	vips/vip-664/bsctestnet.ts	VIP-664 — single REGULAR command sweepTokens(XVS, VTreasury) on the TokenRedeemer, executed by the bsctestnet NormalTimelock.
vips	simulations/vip-664/bsctestnet.ts + abi/{XVS,TokenRedeemer}.json	4-part fork simulation.
venus-protocol-documentation	deployed-contracts/funds.md	TokenRedeemer entry under BNB Chain Testnet.
venus-protocol	deploy/015-deploy-token-redeemer.ts + deployments/bsctestnet/TokenRedeemer.json	Deploy-script patch + artifacts (committed in the deploy phase).

Address verification (three ways agree)

TokenRedeemer = 0x6E78a0d96257F8F2615d72F3ee48cb6fb2c970bd

• Deploy context / answer: 0x6E78…970bd
• venus-protocol/deployments/bsctestnet/TokenRedeemer.json .address: 0x6E78…970bd
• On-chain owner() (chain.call 0x8da5cb5b): 0xce10739590001705F7FF231611ba4A48B2820327 = bsctestnet NormalTimelock ✓

Other addresses (from artifacts + NETWORK_ADDRESSES.bsctestnet):

• XVS 0xB9e0E753630434d7863528cc73CB7AC638a7c8ff
• VTreasury 0x8b293600c50d6fbdc6ed4251cc75ece29880276f

Signature / gate verification

• sweepTokens(address,address) exists in the deployed ABI; source: Currency.wrap(token).transferAll(destination) → transfers the full balance, emitting exactly one ERC-20 Transfer.
• Gate is onlyOwner (owner = NormalTimelock) — no ACM grant and no acceptOwnership() needed (Ownable2Step transfers ownership directly in the constructor).

Simulation (4 parts)

forking(114868878, …) — the block in which TokenRedeemer was deployed (contract present on the fork). before() seeds 1 XVS into the TokenRedeemer from the XVS Vault Proxy whale.

1. Pre-VIP — TokenRedeemer holds the seeded XVS; owner() == NormalTimelock.
2. testVip + expectEvents — full propose→vote→queue→execute; asserts one Transfer.
3. Post-VIP — TokenRedeemer XVS balance == 0 (fully swept).
4. Behavioral proof — Treasury XVS balance == before + swept amount.

$ npx hardhat test simulations/vip-664/bsctestnet.ts --fork bsctestnet
  At block #114868878
  Pre-VIP state
    ✔ TokenRedeemer holds the seeded XVS balance
    ✔ TokenRedeemer is owned by the NormalTimelock
  ... commands
    ✔ executes sweepTokens(address,address) successfully
  ... execution
    ✔ can be proposed
    ✔ should be voteable
    ✔ should be queued successfully
    ✔ should be executed successfully   (gasUsed=133870)
  Post-VIP state
    ✔ TokenRedeemer XVS balance is fully swept to zero
    ✔ Treasury XVS balance increased by the swept amount
  9 passing (25s)

Lint

• npx eslint vips/vip-664/bsctestnet.ts simulations/vip-664/bsctestnet.ts → exit 0.
• npx prettier --check "vips/vip-664/**" "simulations/vip-664/**" → "All matched files use Prettier code style!"
• Note: the full-repo yarn lint OOMs in this environment (V8 heap exhaustion linting the entire repo), unrelated to these files; scoped eslint/prettier are clean.

Risks

• None to mainnet — testnet-only VIP; a plain ERC-20 sweep with no oracle/price dependency and no parameter changes.
