[PASSED] OP-PIP-60: Upgrade Pyth Oracle on TON Testnet

Proposals
1

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

Implementation Plan

Proposal id: Pyth Network

Verify the implementation by comparing the hash:

  • checkout the pyth-crosschain repo
  • 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.
