Commands

IBC Transfer

Transfer tokens from one chain to another using IBC.

Required Options

• --rpc <rpc>: RPC URL of the source chain
• --seed <seed>: Seed phrase/mnemonic for the sender's wallet
• --prefix <prefix>: Bech32 address prefix of the source chain (e.g., "cosmos", "stride", "osmo")
• --gas-price <gasPrice>: Gas price per unit (e.g., "0.025uatom")
• --receiver <receiver>: Destination address to receive tokens
• --amount <amount>: Amount to transfer (e.g., "10uatom")
• --src-channel <srcChannel>: Source channel ID for the IBC transfer

Optional Options

• --gas-adjustment <gasAdjustment>: Gas multiplier for transaction simulation (default: "1.4")
• -v, --verbose: Enable verbose logging (default: false)
• --src-port <srcPort>: Source port for IBC (default: "transfer")
• --timeout <timeout>: Timeout in seconds (default: "180")

Example

cosmcli ibc-transfer \
  --rpc https://rpc.cosmos.network \
  --seed "your mnemonic words here" \
  --prefix cosmos \
  --gas-price 0.025uatom \
  --receiver osmo1yourosmoaddress \
  --amount 10uatom \
  --src-channel channel-141

Response Format

On successful IBC transfer, the tool outputs a JSON object containing:

• tx: Transaction hash on the source chain
• ibcAck: IBC acknowledgement transaction hash

Example output:

{ "tx": "ABC123DEF456GHI789JKL", "ibcAck": "MNO123PQR456STU789VWX" }

Error Handling

If an error occurs, the program will:

1. Print an error message to stderr
2. Exit with a non-zero status code (1)

With the --verbose flag, additional error details and stack traces are provided.
