Deploy and run gfx-swap
Prerequisites
Set the required environment variables to a .env
file
RUST_BACKTRACE=1
RUST_LOG=gfx_swap=info
TOKEN_A=2uig6CL6aQNS8wPL9YmfRNUNcQMgq9purmXK53pzMaQ6
TOKEN_B=8FUPzLY58ojDaj5yh1MKwyJnGNhCDMbStbHNVkBQ9KjJ
ADMIN_WALLET="~/.config/solana/id.json"
USER_WALLET="~/.config/solana/id.json"
You might want to provide different addresses for TOKEN_A and TOKEN_B.
Generate a key for deploying the program
Run just keygen gfx-swap
.
Deploy the program
Run just deploy gfx-swap --features ci
.
Create a swap pool
Run just cli create_pool
.
create_pool
will create the associated token account (ATA) for USER_WALLET
.
This command will print out a bunch of information, in which you need to write down the seed into .env. The seed is a unique identifier to the pool.
Pool monitor
Run just cli pool_status
.
This will print out a snapshot of the current pool status.
You can combine it with the watch
command, i.e. watch just cli pool_status
to constantly monitor the pool.
Deposit tokens into the pool
Run just cli deposit2 --lp-amount <amount>
.
This basically askes the pool I'd like to get <amount> LP tokens and you can deduct some amount of token A and B from my wallet for that.
Withdraw tokens from the pool
Run just cli withdraw2 --lp-amount <amount>
.
This is the inverse operation to the deposit
command.
Swap tokens
Run just cli swap --swap-in A --amount <amount>
.
This swaps in some token A for some token B.
