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
