Welcome to 1delta
A short tour of what 1delta offers - composable margin, swaps, and lending across chains.
What is 1delta?
1delta is a margin and lending aggregator that lets you open collateralised positions across multiple lending markets in a single transaction.
You can read the full docs at https://docs.1delta.io/, and the API reference at https://portal.1delta.io/v1/docs.
Why a margin aggregator?
When you trade on margin you typically have to:
- Deposit collateral into a lending protocol.
- Borrow the asset you want to short or leverage.
- Swap it into the asset you want to be long.
1delta composes those steps into one call, against the best liquidity available on-chain. The result is a single signed transaction that opens the position you asked for - no juggling tabs, no leftover dust.
Example flow
"I want to be 3× long ETH using USDC as collateral, on Polygon."
1delta routes that intent through:
- Lending: deposit USDC, borrow USDC.
- Swap: USDC → ETH at the best venue.
- Settle: redeposit ETH as collateral, atomic.
If any leg fails, the whole bundle reverts. You either get the position you asked for, or nothing.
