IBC Precompile

Transfer funds across chains using the IBC protocol precompile at address 0x0000000000000000000000000000000000001009.

Address: 0x0000000000000000000000000000000000001009

This precompile enables funds transfer over IBC protocol.

Functions

Transactions

• transferWithDefaultTimeout: Send funds to another chain using IBC protocol. Calculates the timeout height/timestamp based on the current block timestamp. For ease of use, this is the recommended way to send out IBC transactions.

  /// Send funds to another chain using IBC protocol. Calculates the timeout height/timestamp
  /// based on the current block timestamp.
  /// @param toAddress The recipient's address on the other chain
  /// @param port IBC port in source chain (e.g. 'transfer')
  /// @param channel IBC channel in source chain (e.g. 'channel-0')
  /// @param denom The denomination of the tokens to send
  /// @param amount The amount of tokens to send
  /// @param memo The memo to include in the transaction, if no memo is needed, pass an empty string
  /// @return Whether the transfer was successfully executed.
  function transferWithDefaultTimeout(
      string toAddress,
      string memory port,
      string memory channel,
      string memory denom,
      uint256 amount,
      string memo
