Rentfree AMM example

Fork of Raydium AMM that creates markets without paying rent-exemption.

• drop-in SDK, minimal code diff
• no extra CU overhead on hot paths
• no UX diff on hot paths

The SDK sponsors rent-exemption on behalf of your users for:

• PoolState
• Token Vaults
• LP Mint account
• User ATAs

Upgrading your program accounts to be rent-free is fast and straightforward because Light-token is a superset of SPL-token. See here for a guide.
