## April 2026

### 2026-04-17 — Direct USDCh → USDC outbound bridge (0% fee)

When the outbound source is USDCh and the destination is canonical USDC,
`/v1/quote` now returns a **fee-free direct Warp Route bridge** instead
of routing through the Hypermid OutboundSender + Piteas. The user signs
a single `transferRemote()` call directly on the USDCh Warp Route and
receives USDC 1:1 on the destination chain.

* **Hypermid fee**: 0 (no contract in the path)
* **DEX slippage**: none (1:1 bridge)
* **Only cost**: Hyperlane gas, paid in PLS from the user's native balance

Quote response shape is unchanged — check `feeBreakdown.totalFeeBps === 0`
and `estimatedOutput === fromAmount` to confirm this path was used. See
the [SuperSwap guide](/guides/superswap#outbound-direct-usdch) for the
full flow.

### 2026-04-16 — SDK 1.2.0: `InboundReceiverParams` shape fix (breaking)

TypeScript SDK bumped to **1.2.0**. The `registerInboundReceiver()` params
interface has been corrected to match the API — the previous shape was never
actually accepted by the backend and all calls were silently failing.

<Warning>
  If you used `hm.registerInboundReceiver()` in your integration, update the
  call — the old shape no longer compiles.
</Warning>

```ts theme={"system"}
// Before (1.1.0) — wrong shape, API rejected these calls
await hm.registerInboundReceiver({
  txHash,
  fromChain: 8453,
  toChain: 369,
  receiverAddress: "0x…",
  outputToken: "0x…",
});

// After (1.2.0) — matches what POST /v1/inbound-receiver/register actually accepts
await hm.registerInboundReceiver({
  txHash,
  fromAddress: "0x…",        // tx sender
  toAddress: "0x…",          // destination on PulseChain
  outputToken: "0x…",        // desired PulseChain token
  destinationDomain: 369,
  signature: "0x…",          // required EIP-712 signature
});
```

### 2026-04-16 — Multi-step SuperSwap (ETH/any token → PulseChain)

`/v1/quote` now returns a multi-step response shape when the source token is
NOT USDC on a supported Sender chain. The frontend widget and SDK handle this
automatically; direct API consumers should check `response.data.quote.type`:

* `type: "multi-step"` → Use `steps[0].transactionRequest` to send, then
  register the deposit with the `afterStep1` payload (see
  [register-inbound-receiver](/api-reference/register-inbound-receiver)).
* No `type` field → Direct single-tx SuperSwap (e.g. USDC on Base → PLS).

### 2026-04-16 — PulseChain bridge status detection fix

The backend was polling the wrong contract for Hyperlane message delivery on
PulseChain, so inbound SuperSwaps appeared stuck even after the bridge landed.
Delivery is now detected correctly using the Hyperlane registry Mailbox
(`0x56176C7F…`). Existing in-flight swaps resolve on the next poll after
deploy — no action required from integrators.

### 2026-04-16 — `/v1/balances` reliability

Multi-chain bulk calls to Alchemy could silently drop entire 5-chain chunks
when one flaky network was in the batch (users most-often saw Base missing).
The endpoint now retries each network individually when a chunk returns
empty, and groups high-traffic chains into the first request. No API shape
change — just more complete results.
