Solana Token 2022 Bridge Upgrade Proposal
Summary
This proposal upgrades the Solana bridge token program and guardian coordination logic to support Solana Token 2022 assets.
Initial support includes governance-approved Token 2022 extensions used for metadata functionality.
Additional extensions may be added to the whitelist through future governance proposals.
Scope of Change
The upgraded bridge system introduces support for Token 2022 assets with approved extensions.
Initial whitelisted extensions include:

- Extension validation coordination
- Updated wrapped token creation flow
