**Abstract**

This PR enhances the Pyth oracle contract on TON by implementing cell chain traversal for price feed ID parsing. The change allows handling more than 3 price feed IDs in a single update by properly managing TON’s cell bit limitations.

**Rationale**

TON cells have a fundamental limitation of 1023 bits per cell. Given that each price feed ID is 256 bits:

- A single cell can only store 3 complete price feed IDs (768 bits)
- Previous implementation would fail when attempting to parse more than 3 IDs
- Applications need to handle more than 3 price feeds in a single update

**Description**

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

- feat(target\_chains/ton): add helper function to parse price IDs beyond a single cell and enhance update handling - [PR 2558](https://github.com/pyth-network/pyth-crosschain/pull/2558)

**Implementation Plan**

Proposal id: [Pyth Network](https://proposals.pyth.network/?tab=proposals&cluster=mainnet-beta&proposal=G3e1i6e9NF6BN7CdGxxFY4ZmZZQTkf9dsJT6JjBvcLJF)

Verify the implementation by comparing the hash:

- checkout the [pyth-crosschain repo](https://github.com/pyth-network/pyth-crosschain)
- `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.

With the 3rd Pythian Council approval passing during this proposal, the initially linked proposal to upgrade the Pyth Oracle on TON testnet has expired and therefore re-submitted
