Package preparation

• Change the package version of @keep-network/tbtc-v2-solana to 1.0.0

Sol on Solana for deployment

• Fund deployment wallet with SOL.

Attest/register token

• Register tBTC token on Solana (L1 tx: https://etherscan.io/tx/0x5d112eb10f9ea3d17ba3a5ddd26fa5c5d71478bf9577a55b934d1789dc5f1aa7, Solana tx: https://solscan.io/tx/387PdEHytCAG2jhheCjc8LP8bskPWYuTAtZUtFKnFeDKdNu8i3jQrxiNgdbztBjYByjbkHvSnGRbgkCWAxaZrhkT)
• Confirm wormhole tBTC token address on Solana (address: 25rXTx9zDZcHyTav5sRqM6YBvTGu9pPH9yv83uAEqbgG)

Smart contracts

The Deployment Team does all the steps.

TODO: depends on #671 (deploy.sh --cluster mainnet-beta)

Tag the new version

The Deployment Team does all the steps

• Create releases/mainnet/cross-chain/solana/v1.0.0 release branch
• Pin mainnet versions in cross-chain/solana/package.json
• Tag cross-chain/solana/v1.0.0
• Sign cross-chain/solana/v1.0.0 commit hash

---

The following steps should be done after the mainnet smoke testing (Ethereum-Solana) is done and no issues are reported.

Update other chains with SolanaWormholeGateway address and chain id.

This will need to be executed by the Threshold Council because they have ownership of the contracts. We should give them JSONs to load into Safe. Navigate to tx builder and prepare JSON for each chain:

• Arbitrum
  Safe
  Contract ABI scroll to the bottom
  Proxy address gateway: https://arbiscan.io/address/0x1293a54e160D1cd7075487898d65266081A15458
• Optimism
  Safe
  Contract ABI scroll to the bottom
  Proxy gateway address: https://optimistic.etherscan.io/address/0x1293a54e160D1cd7075487898d65266081A15458
• Polygon
  Safe
  Contract ABI scroll to the bottom
  Proxy gateway address: https://polygonscan.com/address/0x09959798B95d00a3183d20FaC298E4594E599eab
• Base tbd

convert solana address to base58 - Eth address
ethers.utils.hexZeroPad(hex, 32)

---

The following steps should be done after the rest of mainnet testing is done including Ethereum, Arbitrum, Optimism, Polygon, and Base

Transfer ownership to Threshold Council

• Transfer SolanaTBTC upgrade ownership (tx: tbd)
• Transfer SolanaWormholeGateway upgrade ownership (tx: tbd)

Package publication

Done by the Deployment Team

• Publish cross-chain/solana/v1.0.0 package to NPM
• Publish release notes for cross-chain/solana/v1.0.0

Push deployment artifacts to version control

• Push deployment artifacts to releases/mainnet/cross-chain/solana/v1.0.0 release branch
• Cherry-pick deployment artifacts to the main branch

Post-deployment

• Bump up version in cross-chain/solana/package.json to v1.1.0-dev

Update Threshold docs with new Solana addresses.

• Add Solana for testnet https://docs.threshold.network/resources/contract-addresses/goerli-testnet
• Add Solana for mainnet https://docs.threshold.network/resources/contract-addresses/ethereum-mainnet
