Swap
Any listed token for another, routed through Uniswap v3 and v4 against USDG or WETH, from your wallet or from your Ostra vault.
How a swap goes
The best route goes through a hub, USDG or WETH, over Uniswap v3 and v4 pools, and OstraRouter pays at least the minimum you accept: a wallet swap reverts otherwise, and a vault's order sends the input back. From your Ostra vault, the swap is an escrow order: the vault signs one transfer to an escrow whose address fixes every term, and the Ostra relayer executes it, paid in USDG from the vault, so you need no ETH.
Half of every fee buys $OSTRA for the burn address; the other half goes to Ostra's treasury.
The fee
Lock OSTRA| OSTRA locked for the account | Fee |
|---|---|
| Less than 100,000 | 0.20% |
| 100,000 | 0.15% |
| 250,000 | 0.10% |
| 500,000 | 0% |
A wallet swap pays its sender's fee; a swap from a vault pays the fee of the vault that receives the output. A private swap always pays 0.20%. How Ostra Swap works
