More examples you can find in the following directory: src/tests/.
Code examples to work with Aptos SDK can be found in the examples directory.
Roadmap
- Update to work with the Contract v3
- Prepare transaction payload
- Swap: unstable / stable (normal and high gas)
- Liquidity: add / redeem LP
- Pools: check pool / create pool
- Examples with Aptos SDK
- Staking: stake / harvest / unstake
- Concentrated Liquidity: swap, add, burn
