Events

Swap

event Swap(string fromChain, bytes fromAddr, bytes toAddr, address tokenAddress, bytes32[] bytes32s, uint[] uints, bytes data);

This event occurs when a bridge operator performs bridging with Klaytn Minter through the Orbit Bridge System.

• string fromChain : Chain Symbol requesting bridging

• bytes fromAddr : Address of the chain requesting bridging

• bytes toAddr : Address of chain to execute bridging

• address tokenAddress : Token Address minted by bridging execution

• bytes32[] bytes32s : Bytes32 data array used in the bridging consensus process

• uint[] uints : Uint data array used in the bridging consensus process

• bytes data : Execution data for Bridge Receiver

SwapNFT

event SwapNFT(string fromChain, bytes fromAddr, bytes toAddr, address tokenAddress, bytes32[] bytes32s, uint[] uints, bytes data);

This event occurs when a bridge operator performs NFT bridging with Klaytn Minter through the Orbit Bridge System.

• string fromChain : Chain Symbol requesting bridging

• bytes fromAddr : Address of the chain requesting bridging

• bytes toAddr : Address of chain to execute bridging

• address tokenAddress : Token Address minted by bridging execution

• bytes32[] bytes32s : Bytes32 data array used in the bridging consensus process

• uint[] uints : Uint data array used in the bridging consensus process

• bytes data : Execution data for Bridge Receiver

SwapRequest

event SwapRequest(string toChain, address fromAddr, bytes toAddr, bytes token, address tokenAddress, uint8 decimal, uint amount, uint depositId, bytes data);

Event occurs when a user who uses the Orbit Bridge System requests bridging to Klaytn Minter

• string toChain : Chain Symbol to execute bridging

• bytes fromAddr : Address of the chain requesting bridging

• bytes toAddr : Address of chain to execute bridging

• bytes token : Token Information to be executed bridging

• address tokenAddress : Token Address requesting bridging

• uint8 decimal : Token Decimal requesting bridging

• uint amount : Token Amount requesting bridging

• uint depositId : Unique Identifier of bridging request

• bytes data : Execution data requested for bridging

SwapRequestNFT

event SwapRequestNFT(string toChain, address fromAddr, bytes toAddr, bytes token, address tokenAddress, uint8 decimal, uint amount, uint depositId, bytes data);

Event occurs when a user who uses the Orbit Bridge System requests NFT bridging to Klaytn Minter

• string toChain : Chain Symbol to execute bridging

• bytes fromAddr : Address of the chain requesting bridging

• bytes toAddr : Address of chain to execute bridging

• bytes token : Token Information to be executed bridging

• address tokenAddress : Token Address requesting bridging

• uint tokenId : Token ID requesting bridging

• uint amount : Token Amount requesting bridging

• uint depositId : Unique Identifier of bridging request

• bytes data : Execution data requested for bridging
