Cross Chain Swaps and Transactions

When a user initiates a cross-chain swap, ODX orchestrates a series of actions to execute the transaction seamlessly.

• User requests to swap Asset $A$ on Chain $C$ to Asset $B$ on Chain $D$

• ODX 's Transaction Orchestrator (TO) breaks down the request into atomic operations

• ODX uses the integrated DEX on Chain $C$ (e.g., Uniswap) to swap Asset $A$ to USDT/USDC.

• Swap $A$ to USDT on Chain $C$ using a natively integrated DEX on $C$

• Amount of USDT Received $U_C$:

  $$U_C = A \times P^C_{A \rightarrow USDT}$$

  Where $P^C_{A \rightarrow USDT}$ is the price rate from the DEX on Chain $C$.

• ODX treats USDT on Chain $C$ and Chain $D$ as interchangeable.

• No Bridging or Burning. There is no actual transfer of USDT between chains. ODX 's maintained liquidity allows it to offset the USDT balance internally.

• ODX uses the integrated DEX on Chain $D$ (e.g., Raydium) to swap USDT to Asset $B$.

• Amount of Asset $B$ Received $B_D$:

  $$B_D = U_C \times P^D_{USDT \rightarrow B}$$

  Where $P^D_{USDT \rightarrow B}$ is the price rate from the DEX on Chain $D$.

• The user's ODX account is credited with $B_D$.

• SSE updates the states $S_{B_i}$ for Chains $C$ and $D$.

• ODX confirms transaction completion to the user.
