Loop (Actions)

Leverage, close, collateral-swap, debt-swap

Leverage (loop)

Open a leveraged position via borrow → swap → deposit. Identify the debt market with `marketUidIn` and collateral market with `marketUidOut`. Omit `account` for quote-only (returns `data.quotes` with price deltas). Include `account` to build full transaction calldata (populates `actions` with `alternatives`, `transactions`, and `permissions`).

Leverage loop (simulate)

Open a leveraged position and simulate post-trade state. Same parameters as GET. Optionally send a JSON body with current portfolio state (`balanceData`, `aprData`, `positions`) to receive projected post-trade metrics in the `simulation` field — if omitted, the API fetches balances on-chain automatically. Use the data returned by the user-positions endpoint directly — always include `positions` for accurate health-factor and borrow-capacity projections.

Close margin position

Close a leveraged position. Identify the collateral market with `marketUidIn` and debt market with `marketUidOut`. Omit `account` for quote-only (returns `data.quotes` with price deltas). Include `account` to build full transaction calldata (populates `actions` with `alternatives`, `transactions`, and `permissions`).

Close position (simulate)

Close a leveraged position and simulate post-trade state. Same parameters as GET. Optionally send a JSON body with current portfolio state (`balanceData`, `aprData`, `positions`) to receive projected post-trade metrics in the `simulation` field — if omitted, the API fetches balances on-chain automatically. Use the data returned by the user-positions endpoint directly — always include `positions` for accurate health-factor and borrow-capacity projections.

Refinance / roll-over (move debt to a fixed term)

Move a user's fixed-term debt into a fresh term — 'refinance' / 'roll-over'.

Collateral swap

Swap collateral assets within a lending position. Identify the sell-side collateral market with `marketUidIn` and buy-side with `marketUidOut`. Omit `account` for quote-only (returns `data.quotes` with price deltas). Include `account` to build full transaction calldata (populates `actions` with `alternatives`, `transactions`, and `permissions`).

Collateral swap (simulate)

Swap collateral assets and simulate post-trade state. Same parameters as GET. Optionally send a JSON body with current portfolio state (`balanceData`, `aprData`, `positions`) to receive projected post-trade metrics in the `simulation` field — if omitted, the API fetches balances on-chain automatically. Use the data returned by the user-positions endpoint directly — always include `positions` for accurate health-factor and borrow-capacity projections.

Debt swap

Swap debt between different borrow positions. Identify the repay-side debt market with `marketUidIn` and borrow-side with `marketUidOut`. Omit `account` for quote-only (returns `data.quotes` with price deltas). Include `account` to build full transaction calldata (populates `actions` with `alternatives`, `transactions`, and `permissions`).

Debt swap (simulate)

Swap debt between borrow positions and simulate post-trade state. Same parameters as GET. Optionally send a JSON body with current portfolio state (`balanceData`, `aprData`, `positions`) to receive projected post-trade metrics in the `simulation` field — if omitted, the API fetches balances on-chain automatically. Use the data returned by the user-positions endpoint directly — always include `positions` for accurate health-factor and borrow-capacity projections.

Migrate position (cross-lender)

Move a whole debt + collateral position from one lender to another in a single flash-loan transaction, optionally converting ONE leg (collateral OR debt) via an aggregator swap.

Migration targets for a position

Which markets can this position migrate to? The discovery companion to [`/v1/actions/loop/migrate`](/1delta-api/loop-migrate) — it returns the ranked set of destinations that endpoint would actually accept, so a client never encodes protocol knowledge to build that list.
