New Integrations
- TRUMP on Solana is now available via private swap routes, enabling privacy-preserving swaps for the token on the Solana network.
- Swap status progression is now strictly forward-moving — an issue causing the status to revert from “Swapping” back to “Waiting for deposit” mid-swap has been resolved.
- Order status display on the tracking page is now driven by a unified backend
displayStatusfield, eliminating edge cases where expired or in-progress orders could show conflicting states simultaneously. - SUI DEX swaps using the Max button now reserve sufficient gas for all wallet configurations, preventing
InsufficientCoinBalancefailures at execution time. - Amount-out-of-bounds errors on private swaps are handled more precisely, reducing false rejections on valid swap amounts near provider boundaries.
- The Multiswap Custom mode now shows inline validation warnings on recipient rows where an amount has been entered and then cleared, preventing partial batches from being submitted unintentionally.
- Per-transaction amounts in the Multiswap creation summary now display at full precision, matching the values shown on the order tracking page.
- DEX swaps now require users to confirm the recipient address before the approve and swap transactions are sent to the wallet — a confirmation step that displays the destination address and requires explicit acknowledgment, reducing the risk of funds being sent to custodial or exchange wallets.
- Stellar (XLM) swaps on the order details page now support sending directly from a connected wallet, with native and token transfers both supported.
- The swap button is now disabled when no route is selected, preventing a no-route error from being triggered by an accidental click.
- Partners can now create and manage multiple API keys per account, enabling key rotation workflows and separate credentials for different integrations.
- Private swap quote and exchange endpoints on Partner API v2 now accept optional per-leg provider include/exclude filters, allowing independent provider selection for the in-leg and out-leg of a private swap.
- Partner API v2 now returns a proper validation error (instead of a 500) when non-numeric or unicode characters are passed as amount values.
- Various security and compliance improvements across the platform.

Routing & Pricing
- CowSwap routing on Ethereum has been corrected so native ETH pairs route through the proper path.
- Quotes on low-liquidity BSC pairs are filtered to remove unusable routes before users see them.
- Swap completion amounts are now recorded from provider-confirmed values, so the final receipt reflects the actual payout rather than the pre-swap estimate.
- Route filters apply correctly from the moment quotes start loading — user-selected provider preferences are honored during the initial render.
- Tron DEX swaps now wait for on-chain confirmation before reporting a transaction hash, eliminating premature
pendingstates. - Solana wallet deep links (“Confirm on Wallet” / “Open in Wallet”) now work reliably across mobile and desktop.
- Swap status progresses through to completion in cases where the transaction hash was previously not surfaced.
- The “Connect Wallet” button now responds across all network configurations.
- Resolved a Next.js deployment issue that caused brief page load errors immediately after new releases.
- All legs in a Multiswap order now share the same min/max bounds, keeping displayed limits and accepted values in sync.
- UI polish: capped-height transaction summary panel, row deletion on hover, clearer disabled-button states, same-token validation messaging, and a cleaner recipient address display.
- Per-transaction minimum amounts are now consistent between Multiswap, payment links, and the standard swap flow.
- Redesigned Advanced Settings panel for a cleaner, more intuitive layout.
- The “View Order” button in the active orders popover is now fully visible on smaller screens.
- URL amount parameters using scientific notation (e.g.
?amount=1e5) are now properly sanitized.
- Partner API v2 validation has been hardened — invalid inputs return proper validation errors, unknown query parameters are rejected, and token fields return consistent types.
- The single-token lookup endpoint (
GET /tokens/{id}) is now fully accessible. - Removed an upper-bound limit on quote request amounts.
- Various security and compliance improvements across the platform.
04/28/2026

04/14/2026
New Integrations

- Route sort tabs highlighted — the Best Rate / Fastest sort tabs now have a visual highlight to guide users toward the most relevant option; the Multiswap “New” badge has been retired.
- Partner API v2 significantly hardened — multiple response correctness fixes: proper error codes for disabled/missing tokens, USD output amounts, and a new unified
displayStatusfield that abstracts internal swap leg complexity into a single human-readable status string.
- Various security and compliance improvements across the platform.
03/31/2026

03/09/2026
Routing & Pricing
- Private swaps now check all available routing paths at once and automatically fall back if the first choice is unavailable — fewer failed quotes, smoother experience.
- Integrated live price feeds from Pyth oracle for more accurate real-time token pricing on the swap page.
- Fixed an issue where a provider that couldn’t handle the requested order size could still appear as the best quote — the system now filters out providers that can’t fulfill the amount before showing rates.
