New Feature: Fixed Rate and Reverse Quotes for Private Swaps
- Private swaps now support fixed rates end to end. Locking a rate holds it across both hops of the private route, so the quoted output is what arrives — previously fixed rate was limited to standard swaps.
- Swaps can now be quoted in reverse on standard and private routing. Specify what the recipient should receive and the platform works backwards to the deposit amount, which makes paying an exact invoice or settling a fixed-price order straightforward.
- A private fixed-rate swap that fails part-way through the route returns funds in the token originally sent.
GET /v2/quotesacceptsfixed=truetogether withtypes=private. A newamountType=receiveparameter quotes in reverse from the receive side on standard and private routing, and requires a fixed rate.- Batch orders on
POST /v2/exchanges/multiaccept a per-orderfixedflag withrefundAddressandrefundExtraId. - Refund addresses on memo-bearing chains can now carry a tag via
refundExtraId.

New Feature: EVM Batch Swap
- You can now bundle multiple swaps into a single transaction from an EVM wallet. Combine several trades into one signature and one on-chain deposit, then track every leg from one order view.
