SPL Token-swap (AMM) implemented in Anchor.

First, install dependencies:

$ yarn

Next, we will build and deploy the program via Anchor.

Get the program ID:

$ anchor keys list
anchor_amm: 4CkSf34hTH2rGmgFDCm5WCFE8sHpfdBzrBChEScJBxoM

Here, make sure you update your program ID in Anchor.toml and lib.rs.

Build the program:

$ anchor build

Let's deploy the program. Notice that anchor-amm will be deployed on a mainnet-fork test validator run by Dappio:

$ anchor deploy
...

Program Id: 4CkSf34hTH2rGmgFDCm5WCFE8sHpfdBzrBChEScJBxoM

Deploy success

Finally, run the test:

$ anchor test --skip-build --skip-deploy
