**Abstract**  
This proposal seeks to enhance the Pyth oracle program on TON testnet by introducing a target address and a custom payload parameter to the `parse_price_feed_updates` and `parse_unique_price_feed_updates` functions. These additions are necessary to accommodate TON’s asynchronous architecture, enabling the identification and tracking of specific requests.

**Rationale**  
The recommended flow for protocols is as follows: the user interacts with the Pyth contract, which then sends a message to the target address (in this case, the protocol). To enable the protocol to identify the original caller, the message includes both the sender\_address and a custom\_payload. This ensures the protocol has the necessary information to process the request accurately.

**Description**  
This proposal upgrades the Pyth oracle program on TON with the following major change:

- add target address and custom payload support - [PR 2136](https://github.com/pyth-network/pyth-crosschain/pull/2136)

**Implementation Plan**  
Proposal id: [9dpqFGLkUm3dSZU2cDzKxPVVHQQusmrqva9d3Foo3qH](https://proposals.pyth.network/?tab=proposals&cluster=mainnet-beta&proposal=9dpqFGLkUm3dSZU2cDzKxPVVHQQusmrqva9d3Foo3qH)  
Verify the implementation by comparing the hash:

- checkout the [pyth-crosschain repo](https://github.com/pyth-network/pyth-crosschain)
- install the package dependencies by running `pnpm install --frozen-lockfile`
- `pnpm turbo build --filter "@pythnetwork/pyth-ton"`
- check that the `hash` in the output matches with the `package hash` in the proposal

After this upgrade has been implemented and tested, a subsequent OP-PIP for the TON Mainnet will be introduced.
