[ONGOING] OP-PIP-58: Upgrade Pyth Lazer contract on Solana mainnet (edited)

Proposals
1

Abstract
Following the successful upgrade and testing of the Pyth Lazer contract on Solana testnet and devnet, this proposal intends to upgrade the Lazer contract on Solana mainnet.

Rationale
This proposal upgrades the Pyth Lazer Contract program on Mainnet to add support for ecdsa signatures. Ecdsa signatures are smaller in payload size but are more expensive to verify.

Implementation Plan
Proposal: Realms

Program hash: b790774609fcb6ca5d37bb205ab7e1371a5082aa6770d1d143a0dd44f9f314f9

Proposed program hash can be seen via solana-verify get-buffer-hash 4tdvkVpj4LgRZBMhffG3hzm2xN1u743fndRX2a75dPRX

Verification:

  1. Make sure you have git and rust installed.
  2. git: install git from here
  3. rust: install rust from here
  4. clone the pyth-crosschain repo by running the following command: git clone https://github.com/pyth-network/pyth-crosschain
  5. change your directory to the lazer by running this command: cd pyth-crosschain/lazer/
  6. build the program: solana-verify build --library-name pyth_lazer_solana_contract
  7. check the hash of the artifact: sha256sum ./target/deploy/pyth_lazer_solana_contract.so
  8. check the hash of the deployed buffer
  9. solana program -u m dump 4tdvkVpj4LgRZBMhffG3hzm2xN1u743fndRX2a75dPRX temp_file && sha256sum temp_file && rm temp_file
  10. Make sure the hash from step 8 and from step 7 match
  11. Make sure the buffer authority is the multisig authority
  12. Make a request to get the latest price feed of btc with ecdsa signature using the command below (replace with your token):

curl -X POST -d ‘{“priceFeedIds”: [1], “properties”: [“price”], “chains”: [“evm”], “channel”: “real_time”, “jsonBinaryEncoding”: “hex”}’ -H “Authorization: Bearer ” https://pyth-lazer.dourolabs.app/v1/latest_price

  1. Run cargo run --example parse_and_verify to and paste the evm encoded update data and press enter. You should see the public key 26fb61a864c758ae9fba027a96010480658385b9
  2. Copy the trusted signer from UI and run the following command to make sure it is the same: python3 -c "print(bytearray(<TRUSTED SIGNER [38, 251, ...]>).hex())"
