Testnet report 4 — Bridge microcap

Public testnet day-4: Amoy ↔ Barter bridge under microcaps. Both directions completed at 1 BRTR.

1. Verdict

Day-4 soak is green on public testnet (barter_160993-3 ↔ Polygon Amoy 80002). Amoy → Barter and Barter → Amoy each moved 1 BRTR under caps 100 / tx · 500 / addr / day · 2000 global. Mode is lock-credit / lock-unlock liquidity (no bank mint).

4. Gaps before multi-relayer

  1. Shared Amoy vault with DEV + same EVM id 160993 → transferId(chainId, depositId) collisions (skipped ids 1–3 with 1-wei locks).
  2. Single hot relayer (not 3/5).
  3. Amoy POL gas still scarce for a dedicated vault deploy.
  4. No bridge UI on chain.barter.company yet (DEV has /barter/#bridge).
  5. Portal is pre-funded liquidity, not bank mint.

Do not raise caps or bridge 21M on this path.

5. Next

  • Prefer a dedicated Amoy vault for public testnet.
  • Day-5 DAO pack: summary A1–A4 + explicit do-not list → DAO-2 vote.
