Variants

Initialize(InitializeData)

Tuple Fields

0: InitializeData

Initializes a new SwapInfo.

0. [writable, signer] New StableSwap to create.
1. [] $authority derived from create_program_address(&[StableSwap account])
2. [] admin Account.
3. [] admin_fee_a admin fee Account for token_a.
4. [] admin_fee_b admin fee Account for token_b.
5. [] token_a Account. Must be non zero, owned by $authority.
6. [] token_b Account. Must be non zero, owned by $authority.
7. [writable] Pool Token Mint. Must be empty, owned by $authority.

Swap(SwapData)

Tuple Fields

0: SwapData

Swap the tokens in the pool.

0. []StableSwap
1. [] $authority
2. [writable] token_(A|B) SOURCE Account, amount is transferable by $authority,
3. [writable] token_(A|B) Base Account to swap INTO. Must be the SOURCE token.
4. [writable] token_(A|B) Base Account to swap FROM. Must be the DESTINATION token.
5. [writable] token_(A|B) DESTINATION Account assigned to USER as the owner.
6. [writable] token_(A|B) admin fee Account. Must have same mint as DESTINATION token.
7. [] Token program id

Deposit(DepositData)

Tuple Fields

0: DepositData

0. []StableSwap
1. [] $authority
2. [writable] token_a $authority can transfer amount,
3. [writable] token_b $authority can transfer amount,
4. [writable] token_a Base Account to deposit into.
5. [writable] token_b Base Account to deposit into.
6. [writable] Pool MINT account, $authority is the owner.
7. [writable] Pool Account to deposit the generated tokens, user is the owner.
8. [] Token program id
9. [] Clock sysvar

Withdraw(WithdrawData)

Tuple Fields

0: WithdrawData

Withdraw tokens from the pool at the current ratio.

0. []StableSwap
1. [] $authority
2. [writable] Pool mint account, $authority is the owner
3. [writable] SOURCE Pool account, amount is transferable by $authority.
4. [writable] token_a Swap Account to withdraw FROM.
5. [writable] token_b Swap Account to withdraw FROM.
6. [writable] token_a user Account to credit.
7. [writable] token_b user Account to credit.
8. [writable] admin_fee_a admin fee Account for token_a.
9. [writable] admin_fee_b admin fee Account for token_b.
10. [] Token program id

WithdrawOne(WithdrawOneData)

Tuple Fields

0: WithdrawOneData

Withdraw one token from the pool at the current ratio.

0. []StableSwap
1. [] $authority
2. [writable] Pool mint account, $authority is the owner
3. [writable] SOURCE Pool account, amount is transferable by $authority.
4. [writable] token_(A|B) BASE token Swap Account to withdraw FROM.
5. [writable] token_(A|B) QUOTE token Swap Account to exchange to base token.
6. [writable] token_(A|B) BASE token user Account to credit.
7. [writable] token_(A|B) admin fee Account. Must have same mint as BASE token.
8. [] Token program id
9. [] Clock sysvar
