Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (15)

### `explain` (~36 tokens)

Explain FlashBank

Plain-English primer on both FlashBank products, the loan lifecycle, fees and safety rules. Call this first if you are unsure how anything works.

### `list_chains` (~26 tokens)

List chains

Supported chains with contract addresses, registry tokens and whether writes are currently permitted for each.

### `wallet_status` (~45 tokens)

Wallet status

Address, native balance and registry-token balances of the configured signing wallet on one chain. Reports read-only mode when no key is set.

Input parameters:

- `chain` (string, required): Chain to inspect

### `p2p_list_offers` (~74 tokens)

List open P2P offers

Open, takeable loan offers/requests on a chain, newest first with boosted (featured) offers ranked on top. Returns human-readable terms plus the raw ids for follow-up calls.

Input parameters:

- `chain` (string, required): Chain to browse
- `limit` (integer): Max offers to return (default 20)

### `p2p_get_loan` (~62 tokens)

Get P2P loan detail

Full detail for one loan id: terms, parties, status, what a taker must provide, repayment quote, default deadline/split and the on-chain terms hash.

Input parameters:

- `chain` (string, required)
- `id` (integer, required): Loan id

### `p2p_my_loans` (~56 tokens)

My P2P loans

Every loan created by or assigned to an address (defaults to the configured wallet), with current status.

Input parameters:

- `address` (string): Address to look up (defaults to the signing wallet)
- `chain` (string, required)

### `flash_pools` (~43 tokens)

Flash-loan pools

Per-token flash-loan liquidity on a chain: committed amount, live available liquidity, fee, per-loan cap and provider count.

Input parameters:

- `chain` (string, required)

### `flash_quote` (~76 tokens)

Quote a flash loan

Fee quote for flash-borrowing a given amount of a token (symbol or address) on a chain.

Input parameters:

- `amount` (string, required): Human amount to borrow, e.g. "250"
- `chain` (string, required)
- `token` (string, required): Token symbol (e.g. "WETH") or 0x address

### `p2p_create_offer` (~359 tokens)

Create a P2P offer

Post a loan offer (you lend) or borrow request (you borrow) on-chain. Escrows your side immediately: lenders escrow the principal, borrowers escrow the collateral. Reversible via p2p_cancel while untaken. Requires a signing key; mainnet additionally requires FLASHBANK_MCP_ALLOW_MAINNET=true.

Input parameters:

- `allowedTaker` (string): Restrict who may take (address). Omit for open market.
- `chain` (string, required)
- `collateral` (string, required): Collateral amount (human units)
- `collateralToken` (string, required): Token pledged as collateral — symbol or address
- `coolingOffHours` (number): v2 chains (Sepolia) only: cooling-off window in hours over which the fee vests. Omit or 0 = the protocol minimum for the term; longer is allowed, shorter rejects.
- `durationDays` (number, required): Loan term in days
- `flatFee` (string, required): Flat repayment fee in principal-token units (e.g. "30" = repay principal + 30). NOT a percentage.
- `graceDays` (number): Grace period after maturity (days, default 1)
- `offerExpiryHours` (number): Hours until the un-taken offer expires (default: never)
- `principal` (string, required): Principal amount (human units, e.g. "1000")
- `principalToken` (string, required): Token being lent — symbol or address
- `settlementValue` (string): Agreed value of ALL the collateral in principal-token units; surplus above the debt returns to the borrower on default. Omit for full forfeit.
- `side` (string, required): "lend" = you provide the principal; "borrow" = you provide the collateral

### `p2p_take_offer` (~94 tokens)

Take a P2P offer

Accept an open offer, pinning the EXACT terms currently on-chain (takeWithTerms) so a last-second re-price reverts instead of surprising you. Approves and escrows your side, which activates the loan — a BINDING commitment until repaid or defaulted. Requires a signing key (mainnet gated).

Input parameters:

- `chain` (string, required)
- `id` (integer, required): Loan id to take

### `p2p_repay` (~86 tokens)

Repay a P2P loan

Repay an active loan you borrowed, redeeming your collateral. On v2 chains (Sepolia) the fee is the VESTED amount — repaying inside the cooling-off window is rebated down to a 10% floor. Requires the signing wallet to be the borrower (mainnet gated).

Input parameters:

- `chain` (string, required)
- `id` (integer, required)

### `p2p_claim_default` (~67 tokens)

Claim a defaulted P2P loan

After the repay window closes unpaid, the lender claims the collateral (any agreed surplus returns to the borrower). Irreversibly settles the loan. Requires the signing wallet to be the lender (mainnet gated).

Input parameters:

- `chain` (string, required)
- `id` (integer, required)

### `p2p_cancel` (~51 tokens)

Cancel an open P2P offer

Cancel an offer you created that has not been taken, reclaiming your escrow (any boost spend is not refunded). Mainnet gated.

Input parameters:

- `chain` (string, required)
- `id` (integer, required)

### `p2p_withdraw_unclaimed` (~84 tokens)

Withdraw queued payouts (v2)

v2 chains (Sepolia) only: if a settlement payout to you could not be delivered (e.g. a blocklisting token), it queues on-chain — this checks your queued balance for a token and withdraws it.

Input parameters:

- `chain` (string, required)
- `token` (string, required): Token symbol or 0x address the payout was in

### `faucet_mint` (~61 tokens)

Mint Sepolia play-money

Mint a free batch of 10,000 fpUSD or fpETH (valueless playground tokens) to the signing wallet on Sepolia. The safe way for agents to get funds to experiment with.

Input parameters:

- `token` (string, required): Which playground token to mint
