Authorizations

​
x-api-key
string
header
required

Your Compass API Key. Get your key here.

Body

application/json

Unwind a leveraged loop: repeatedly withdraw collateral, swap it back to the borrow token at a guaranteed minimum output, and repay — all in ONE atomic transaction from the Credit Account.

​
owner
string
default:0x0E407CdeBD8e078E6966ef6740540d25F5897082
required

The address that owns the Credit Account.

Example:

"0x0E407CdeBD8e078E6966ef6740540d25F5897082"

​
chain
enum<string>
default:ethereum
required

Blockchain network.

Available options:
base,
ethereum,
arbitrum,
hyperevm,
tempo,
bsc
Example:

"ethereum"

​
collateral_token
string
default:WETH
required

Token supplied as collateral in the loop being unwound. For MORPHO it must be the market's collateral token.

Examples:

"wstETH"

"WETH"

​
borrow_token
string
default:USDC
required

Token borrowed in the loop; withdrawn collateral is swapped back to it and used to repay. For MORPHO it must be the market's loan token.

Examples:

"WETH"

"USDC"

​
protocol
enum<string>
default:AAVE

Lending protocol to unwind: AAVE, MORPHO, or EULER.

Available options:
AAVE,
EULER,
MORPHO
Example:

"AAVE"

​
market_id
string | null

Morpho only: the bytes32 market id (from /v2/credit/morpho_markets). Required when protocol=MORPHO.

​
collateral_vault
string | null

Euler only: the EVK vault the loop's collateral is in. Required when protocol=EULER.

​
borrow_vault
string | null

Euler only: the EVK vault the loop borrowed from (the sub-account's controller). Required when protocol=EULER.

​
sub_account_id
integer
default:0

Euler only: the EVC sub-account (0-255) holding the looped position to unwind. 0 is the Credit Account itself.

Required range: 0 <= x <= 255
​
target_multiplier

Target leverage after the unwind. Omit (null) for a FULL unwind: the debt is cleared exactly — accrued interest included — and all pair collateral is withdrawn back to the Credit Account. 1 runs the same exact debt close but leaves the collateral supplied (earning). A value greater than 1 delevers the position to that multiplier. Must be below the position's current multiplier.

Required range: x >= 1
Example:

2

​
max_slippage_percent
default:0.5

Per-swap slippage tolerance in percent. Unwind dust is bounded by this per iteration, so tighter slippage means less dust.

Required range: 0 < x <= 10
Example:

0.3

​
allow_partial
boolean
default:false

If the target cannot be reached in one transaction (e.g. a position opened very close to the liquidation threshold), return the maximum-progress plan (preview.fully_unwound=false) instead of a 400. A second unloop call, now from a much lower leverage, finishes the job.

Example:

false

​
gas_sponsorship
boolean
default:false

If true, returns EIP-712 typed data for gas-sponsored execution instead of an unsigned transaction.

Example:

false

Response

Successful Response

The atomic unwind transaction plus its guaranteed-floor preview.

​
preview
CreditUnloopPreview · object
required

Projected end state, computed on guaranteed swap floors.

​
transaction
UnsignedTransaction · object | null

Unsigned transaction for direct execution by the owner. Present when gas_sponsorship=false.
