[PASSED] OP-PIP-96: Enable Trusted Signer for Pyth Lazer on Sui (mainnet & testnet)

Proposals
1

Abstract
Perform a trusted signer update on Sui Lazer contracts to allow processing of user requests. This proposal enables signer key 03a4380f01136eb2640f90c17e1e319e02bbafbeef2e6e67dc48af53f9827e155b with expiration time 2027-02-13T06:26:40.000Z.

Rationale
Once deployed, Sui Lazer contracts can only have their configuration changed through proposal process, including trusted signers set. Contracts are deployed with empty configuration, effectively making them unable to process user requests until they receive initial configuration through proposal process.

Description
Proposal should emit a single Wormhole message targeted to Sui chain, with key configuration mentioned above.

Implementation plan
Proposal ID: 7Jo7BWbTwUnbEwTMgQETR5UovvLZXyKZPVJZ29mDJ2CV

Proposal verification

Install pnpm and jq

Clone the pyth-crosschain repository, build contract_manager, and run check_proposal script:

git clone https://github.com/pyth-network/pyth-crosschain \
  --branch lazer-proposal-test
cd pyth-crosschain

pnpm install && pnpm turbo build
pnpm tsx scripts/check_proposal.ts
  --cluster mainnet-beta \
  --proposal 7Jo7BWbTwUnbEwTMgQETR5UovvLZXyKZPVJZ29mDJ2CV

Script should respond with the following output:

secp256k1 unavailable, reverting to browser version

Dear @KemarTiti,

I am a bit curious, if Pyth Lazer is live on Sui, are all dApps on SUI will be allowed to use the feed?

Or would each dApp have to pay separately for an api key to acess the lazer feed?

How is it compared with the integration in Cardano?

Great question!

1st it is important to understand that it will work the same for all chains: Sui, Solana, any EVMs, etc…

Pyth Core (Price Feeds)

  1. Anyone can fetch price proofs from Hermes at no cost
  2. Anyone can submit those proofs to the public smart contracts
  3. Contracts store the latest price onchain
  4. :warning: Free-riding possible: once a price is pushed onchain, others can read it without paying

Pyth Lazer (Pro)

  1. You must have a Pyth Pro API key to receive Lazer price updates
  2. Only with that key can you get the signed data needed to interact with the contracts
  3. Contracts do not store prices — they only verify and pass through
  4. :white_check_mark: No free-riding: without API access, you can’t get the data to use the contracts

TLDR: The gate for Pro/Lazer is at the offchain layer — even though contracts are public, you can’t use them without first having API access to fetch the signed price data.

@KemarTiti thanks for the quick reply,

A followup question. What about pyth integration on fogo chain? I think Pyth lazer is enshrined in the blockchain.

It has been deployed already – for Pyth Lazer/Pro official/public deployments, check the docs: Contract Addresses | Pyth Developer Hub

Thanks for the reply. I am looking forward to see more chains integrating pyth lazer directly.
