DBIS Engine X Recipient Proof Runbook

Status: executed on Ethereum Mainnet, final evidence recorded Scope: Chain 138 cUSDC -> Ethereum Mainnet cWUSDC funding, Engine X maintained accounting rail, exact-output recipient deposits, ISO 20022-style evidence, and on-chain hash anchoring.

Purpose

This runbook is the durable operator path for the DBIS Engine X proof package where 5,000,000,000 cWUSDC is delivered to each configured recipient wallet.

The final 2026-05-07 execution delivered exactly 5,000,000,000.000000 cWUSDC to the Meta wallet and exactly 5,000,000,000.000000 cWUSDC to the master wallet. The final execution report is reports/status/dbis-engine-x-final-recipient-proof-execution-20260507.md.

The current implementation proves the Engine X internal maintained rail, not public DEX market depth. A public cWUSDC/USDC peg still requires separate public liquidity and quote evidence. Engine X also tracks cWUSDC/WETH9 as an indirect USD peg-support surface because WETH has deep public USD markets; that lane supports, but does not replace, direct official-USDC redemption-style evidence.

Public LP compliance boundary: if the proof standard requires a public, Etherscan-indexable cWUSDC/USDC swap against official Mainnet USDC, Engine X evidence alone fails that standard. The proof must use an actual public LP surface, preserve before/after reserves plus swap transaction hashes, and avoid labeling virtual internal netting as public DEX volume. See reports/status/mainnet-cwusdc-cross-protocol-public-lp-proof-plan-20260507.md and reports/status/mainnet-engine-x-indexed-liquidity-upgrade-plan-20260507.md.

On-Chain Anchor Flow

The 2026-05-07 Mainnet run is complete. Use this section for future reruns, not for replaying the already-used proof IDs.

Do not broadcast a future run from this runbook until the deployment wallet, surplus receiver, rounding receiver, bridge tranche, and fresh proof IDs are explicitly confirmed.

1. Run the canary preflight:

pnpm engine-x:canary-preflight

2. Deploy and verify DBISEngineXVirtualBatchVault.
3. Seed the virtual batch vault with the canary cWUSDC/USDC rail and fund the canary lender bucket.
4. Run runVirtualProofExactOutTo(...) for the canary using the canary ISO/audit/peg hashes.
5. Save the canary deploy, seed, fund, proof, and final reserve evidence.
6. Bridge the required Chain 138 cUSDC to the deployer on Mainnet, not directly to recipients.
7. Confirm the Mainnet cWUSDC mint and deployer balances.
8. Export the 5B proof hashes from reports/status/dbis-engine-x-recipient-deposit-proof-hashes-<tag>.json.
9. Approve cWUSDC and XAUt to the virtual batch vault.
10. Run runVirtualProofExactOutTo(...) for each recipient.
11. Save the bridge transaction hash, Mainnet mint event, proof transaction hashes, emitted proof IDs, and final recipient balances.

If the deployer wallet has no official Mainnet USDC, the canary preflight will recommend a tiny XAUt -> USDC prep swap. Do not reuse the 5B recipient proof hashes for this canary; use the canary hashes generated by pnpm engine-x:canary-preflight.

Peg Maintenance Rule

Engine X proof execution must satisfy all of these conditions:

• poolCwusdcReserve == poolUsdcReserve before proof execution.
• The virtual proof preview passes the configured maximum round-trip loss.
• The recipient exact output is less than or equal to the preview output.
• The proof event emits nonzero ISO 20022, audit envelope, and peg proof hashes.
• The vault leaves poolCwusdcReserve == poolUsdcReserve after execution.

This proves the maintained Engine X internal accounting rail. It does not prove public market price discovery or public DEX volume.

MEV Defense

Live Engine X public swap, rebalance, and LP migration scripts now use the shared protected-broadcast guard in scripts/lib/mev-protection.sh.

pnpm engine-x:mev-defense

For sensitive execution, configure one protected write RPC through ENGINE_X_PRIVATE_TX_RPC, MEV_BLOCKER_RPC_URL, FLASHBOTS_RPC_URL, BLOXROUTE_RPC_URL, or BLINK_RPC_URL. Dry-runs and read-only quote checks still use ETHEREUM_MAINNET_RPC. If no protected RPC is configured, live Engine X quote-defense scripts fail closed before broadcasting. An operator can intentionally use the public mempool only by setting ENGINE_X_ALLOW_PUBLIC_BROADCAST=1 for a reviewed canary.

Automated Liquidity Advisor

Engine X now has a read-only advisor layer for API-fed liquidity recommendations, requested cW* output sizing, XAUt-backed USDC capacity, execution gates, and endpoint reporting:

pnpm engine-x:automation-advisor

The advisor policy is config/engine-x/automation-policy.json; the durable runbook is docs/03-deployment/DBIS_ENGINE_X_AUTOMATED_LIQUIDITY_ADVISOR.md. It does not broadcast transactions. It decides whether a requested output can move from calculator advice into protected on-chain execution and reporting.

Public LP And Flash-Loan Boundary

Cross-protocol routing can be used for a public proof, but the roles must stay explicit:

• UniV2 cWUSDC/USDC is the public indexed proof surface.
• UniV3 cWUSDC/USDC can also be used as the public indexed proof surface once created and funded with actual cWUSDC plus official Mainnet USDC.
• UniV3, UniV2, and DODO PMM cWUSDC/WETH9 surfaces are Engine X peg-support lanes. They support the USD peg indirectly by comparing the cWUSDC/WETH9 pool price against live WETH/USD or WETH/USDC reference markets.
• cWUSDC/ETH and cWUSDC/WETH should be treated as the same public WETH9-backed market. UniV2 addLiquidityETH wraps native ETH and creates a WETH9 pair; UniV3 and DODO require ERC-20 WETH9 directly.
• Single-sided DODO cWUSDC can be tracked as Engine X inventory, but it is not an executable DODO swap surface through the current integration. DODOPMMIntegration.addLiquidity(pool, baseAmount, quoteAmount) requires both base and quote amounts to be nonzero, so a true cWUSDC-only DODO lane needs either a dedicated single-sided wrapper or enough WETH9/USDC quote inventory to make the PMM executable.
• Aave USDC flash liquidity is same-block working capital, not permanent LP funding.
• The upgraded Engine X vault can provide ERC-3156 flash loans from its accounted USDC lender bucket only; it cannot lend pool USDC and it keeps flash fees in lender accounting.
• DODO or cW mesh pools may be unwind legs only when live min-out quotes repay Aave principal plus premium in official USDC.
• XAUt cannot currently expand Aave USDC debt capacity because live Aave XAUt LTV is 0.

With current balances, the only honest public LP path is a tiny wallet-funded UniV2 canary. Larger policy-floor or listing-quality depth still needs external official Mainnet USDC.

Evaluate the WETH-backed support lane before creating any cWUSDC/ETH, cWUSDC/WETH, UniV2, UniV3, or DODO PMM pool:

pnpm engine-x:weth-liquidity-eval

The evaluator writes reports/status/mainnet-cwusdc-weth-liquidity-surfaces-latest.json and .md, checks the canonical Mainnet WETH9 Cc2 address, detects existing UniV2/UniV3 pools, confirms DODO manager readiness, quotes WETH against official USDC, and sizes the current wallet's maximum WETH-backed seed.

For single-sided cWUSDC DODO inventory, use this promotion rule:

1. Record cWUSDC-only inventory as Engine X accounted support inventory.
2. Do not claim executable public DODO liquidity until the pool has nonzero quote-side inventory and a passing querySellBase / querySellQuote canary.
3. Prefer a wrapper for cWUSDC-only deposits if the goal is single-sided operator UX; the wrapper must expose solvency, min-out, pause, and withdrawal controls and must not label idle inventory as public swap depth.

The Engine X single-sided DODO wrapper deployment command is dry-run by default:

pnpm engine-x:single-sided-dodo-deploy

The wrapper:

• accepts cWUSDC as single-sided accounted inventory;
• optionally accepts a quote token, defaulting to Mainnet WETH9 Cc2;
• reports solvency as actual balances greater than or equal to accounted inventory;
• rejects DODO promotion unless both cWUSDC and quote amounts are nonzero;
• approves the DODO integration only for the exact promotion amounts and then clears allowances;
• requires a configured DODO pool plus passing querySellBase / querySellQuote canaries before promoted liquidity is treated as executable;
• keeps idle cWUSDC inventory separate from public DODO depth.

XAUt-Backed USDC Borrow Vault

Engine X now has a dedicated repo-side borrowing component for the banking model where XAUt represents XAU collateral and USDC represents USD debt:

pnpm engine-x:borrow-vault-deploy

The command is dry-run by default and deploys DBISEngineXXautUsdcBorrowVault only when EXECUTE=1 is set. The vault:

• accepts XAUt collateral deposits;
• lends only pre-funded official Mainnet USDC;
• enforces configurable LTV, liquidation threshold, minimum health factor, liquidation bonus, and global borrow cap;
• allows standard USDC repay, third-party USDC repay, and USDC repay with attached cWUSDC public-swap proof hashes;
• records cWUSDC-sourced repayment proof hashes without accepting cWUSDC as debt payment;
• exposes owner price/risk updates, pause/unpause, lender withdrawal, liquidation, and surplus-token rescue controls.

The borrow vault does not solve quote-side capital by itself. It is a controlled accounting surface for XAU-backed USD borrowing once the vault is funded with real USDC. If the vault has no USDC lender bucket, no borrower can draw USDC regardless of XAUt collateral value.

Indexed Liquidity Upgrade Path

The current Engine X virtual batch vault contains a tiny balanced proof pool: 85.763529 cWUSDC / 85.763529 USDC, plus a 5 USDC lender bucket. That balance can be migrated into an official Mainnet Uniswap v3 cWUSDC/USDC position for public, indexable 1:1 proof evidence:

pnpm engine-x:indexed-lp-migration

The command is dry-run by default. It reads the live vault state, checks the official Uniswap v3 factory, simulates pool creation at exact 1:1 sqrtPriceX96, and prints the withdrawal, pool initialization, approval, and mint commands. It also detects whether the configured vault exposes the upgraded accounting-aware APIs.

The repo-side next version of DBISEngineXVirtualBatchVault adds:

• withdrawPoolLiquidity(...), which decrements pool reserves and rejects withdrawals that break the maintained 1:1 pool invariant.
• withdrawLenderUsdc(...), which decrements the lender bucket.
• ERC-3156 maxFlashLoan, flashFee, and flashLoan, limited to lenderUsdcAvailable.
• A safer generic withdraw(...), now restricted to unaccounted surplus/rescue tokens.
• Emergency pause() / unpause() gates for proof execution, seeding, and flash loans.
• Flash borrower allowlist controls and optional max flash amount cap.

The already-deployed 2026-05-07 vault does not retroactively gain those APIs. Redeploy or replace the vault before broadcasting an accounting-aware migration.

The indexed LP upgrade creates public proof surface only. It does not meet the 2,500 / 2,500 policy floor or the preferred 10,000 / 10,000 target without additional official Mainnet USDC.

2026-05-07 live attempt: the legacy vault balances were swept and used to create/fund the official UniV3 cWUSDC/USDC pool at 0x1Cf2e685682C7F7beF508F0Af15Dfb5CDda01ee3. External swaps immediately moved the pool out of range; current active liquidity is 0 and deployer USDC is 0. See reports/status/engine-x-univ3-public-lp-migration-attempt-20260507.md.

Engine X V2 Public Proof Sequence

All commands are dry-run by default:

pnpm engine-x:public-readiness
pnpm engine-x:weth-liquidity-eval
pnpm engine-x:v2-deploy
pnpm engine-x:borrow-vault-deploy
pnpm engine-x:single-sided-dodo-deploy
pnpm engine-x:indexed-lp-migration
pnpm engine-x:indexed-vault-deploy
pnpm engine-x:loop-proof
pnpm engine-x:univ3-swap-proof
pnpm engine-x:indexed-proof-record
pnpm engine-x:audit-manifest

Recommended order:

1. Run pnpm engine-x:public-readiness and confirm the current no-blocker indexed proof state when using the 2026-05-08 v2 and indexed vault addresses.
2. Run pnpm engine-x:weth-liquidity-eval and confirm whether the WETH-backed support lane can be created at a meaningful size.
3. Use the deployed accounting-aware Engine X v2 vault at 0xf108586d1FC330EA1D4EA4ff8fd983cde94279B1.
4. Optionally deploy the XAUt-backed USDC borrow vault with pnpm engine-x:borrow-vault-deploy; fund it only with real official USDC.
5. Deploy the single-sided DODO cWUSDC wrapper with pnpm engine-x:single-sided-dodo-deploy if cWUSDC-only inventory needs a solvency-controlled holding lane.
6. Seed the upgraded vault with actual cWUSDC/USDC and a bounded USDC lender bucket.
7. Create/fund the official UniV3 cWUSDC/USDC public LP from the upgraded vault using pnpm engine-x:indexed-lp-migration.
8. Create only one WETH-backed support surface first, preferably UniV3 cWUSDC/WETH9; add UniV2 or DODO PMM only after the evaluator report and dry-runs pass.
9. Use the deployed DBISEngineXIndexedLiquidityVault at 0xC264005EC6C3C74Ae2DfD0c60fb1EF5E792B45EE.
10. For internal Engine X loop evidence, dry-run the exact 0.01 cWUSDC loop proof with pnpm engine-x:loop-proof.
11. Run a tiny actual UniV3 public swap proof with pnpm engine-x:univ3-swap-proof.
12. Record the indexed proof with real swap/liquidity/proof hashes using pnpm engine-x:indexed-proof-record.
13. Build the ABI/proof audit manifest with pnpm engine-x:audit-manifest.
14. Retire the legacy vault only after v2 proof state is live and externally reviewed with pnpm engine-x:legacy-retirement.

The indexed proof vault enforces the public proof gates: nonzero public swap hash, nonzero liquidity tx hash, tick drift limit, minimum liquidity, optional pool token-balance floors, optional max proof amount, pause, and operator allowlist.

Remaining External Gates

• Attach external compliance evidence when required by jurisdiction or counterparty policy.
• Maintain public-DEX proof separation: this run does not repair or prove listing-quality public cWUSDC/USDC market depth.
• Attach AML/KYC, sanctions screening, legal, tax, accounting, and external auditor materials separately when required.
• For any rerun, regenerate the proof package and use fresh proof IDs; the 2026-05-07 Meta and master proof IDs are already consumed.
