Prop 351: Pin Contract Codes (v0.9.1 - Solana Metis USDC)

Summary

As noted in the prior pinning proposals, contracts stored on-chain remain unpinned by default, requiring on-chain storage lookups on every execution. Pinning keeps a contract's code in memory instead, reducing gas costs for every transaction that touches it.

This proposal pins the 7 contract codes just stored for the v0.9.1 release of the Solana Metis USDC protocol: Leaser (922), Lease (921), LPP (923), Oracle (924), Profit (925), Reserve (927), Remote Lease controller (926). These codes are the target of the accompanying migration proposal for the SOLANA-METIS-USDC protocol on the Nolus Pirin mainnet; pinning them ahead of the migration means the migrated contracts execute from memory from their first block.

For the complete changelog, please refer to the release v0.9.1 on GitHub.

By voting "YES" to this proposal you agree to pin these 7 contract code IDs.
