Roadmap

• [x] Update to work with the Contract v3
• [x] Prepare transaction payload
• [x] Swap: unstable / stable (normal and high gas)
• [x] Liquidity: add / redeem LP
• [x] Pools: check pool / create pool
• [x] Examples with Aptos SDK
• [ ] Staking: stake / harvest / unstake
• [ ] Concentrated Liquidity: swap, add, burn
