This page lists all deployed addresses for the Stableswapper program. Reference these when constructing transactions or integrating with the contract.
These docs currently show devnet/testnet addresses only. Do not use these addresses on mainnet. Mainnet addresses will be provided during your production onboarding.

Program Derived Addresses (PDAs)
These accounts are deterministically derived from the program ID using the seeds shown. You do not need to store them — derive them at runtime using PublicKey.findProgramAddressSync.| Account | Address | Seeds | Role |
|---|
| Pool | 68xwTJYRyUdULbb5ve4JMWTc2xvw9wQmtEj9GRoHSenF | ["liquidity_pool"] | Central pool state — holds fee rate, fee recipient, and supported vault list |
| Whitelist | 8zVAo6z2juAcVMkn3booA4yMGym5BPUJey2iN1Nq7Hvr | ["address_whitelist"] | Address allowlist checked against the transaction signer on every swap |
// Vault PDA (logical owner for a token's reserves)
const [vault] = PublicKey.findProgramAddressSync(
[Buffer.from("token_vault"), pool.toBuffer(), mintAddress.toBuffer()],
programId
);
// Vault Token Account (where reserves actually live)
const [vaultTokenAccount] = PublicKey.findProgramAddressSync(
[Buffer.from("vault_token_account"), vault.toBuffer()],
programId
);
Constant Program Addresses

Privacy notice: All transactions on devnet and testnet blockchains are publicly visible. To protect your privacy during testing, we recommend using a dedicated test wallet rather than a personal wallet, as your wallet address and transaction history may be viewable by anyone on the blockchain.
