This guide provides a technical overview for developers looking to integrate with Fluxbeam DEX Solana, the first DEX on Solana to fully support the Fluxbeam SPL22 Extension.
Step 1: The Core Innovation - Token-2022 (SPL22)
The key differentiator for Fluxbeam is its native support for the new Token-2022 standard on Solana. This isn't just an update; it unlocks powerful new token features that developers must account for:
Transfer Fees: Tokens can now have a built-in fee on every transfer, allowing DAOs and projects to generate revenue directly.
Interest-Bearing Tokens: Tokens can accrue interest natively, perfect for LSTs.
Confidential Transfers: Support for privacy-preserving transfers.
And more: Non-transferable tokens, permanent delegates, etc.
Step 2: Programmatic Swaps with SPL22
When you build an interface to Swap on Fluxbeam, the process is similar to a standard swap, but you must account for the new extensions.
Query Fees: Before executing a swap involving an SPL22 token, your dApp must query the token's mint account to determine if a transfer fee exists.
Calculate Expected Output: Your slippage calculations must factor in the potential transfer fees on both the input and output tokens.
Execute: The Fluxbeam.xyz Exchange router handles the complex logic, but your front-end must accurately represent the final amounts to the user.
Step 3: Providing Liquidity for SPL22 Tokens
Integrating with Fluxbeam Liquidity Pools containing SPL22 tokens also requires special care. The AMM is designed to handle the transfer fees, ensuring that fees are correctly accounted for when liquidity is added or removed.
Step 4: Security and Further Integration
The question "Is Fluxbeam Safe?" is addressed by its audited contracts and its focus on supporting a Solana-native standard. Developers can further integrate with Fluxbeam Yield Farming contracts to allow users to stake their LP tokens and earn FLUXB Token rewards.
