Transactions

Look up individual transactions or search for transactions matching specific criteria.

Get Transaction by Hash

Retrieve a single transaction and its execution result by its hash.

curl http://67.205.164.156:1317/cosmos/tx/v1beta1/txs/A1B2C3D4E5F6...

Key Fields

Field	Description
`tx.body.messages`	Array of messages (actions) in this transaction
`tx.auth_info.fee`	Gas fee paid by the signer
`tx_response.code`	`0` = success, non-zero = error (see `raw_log` for details)
`tx_response.height`	Block height where this tx was included
`tx_response.gas_wanted` / `gas_used`	Gas limits and actual consumption
`tx_response.events`	Emitted events (useful for tracking wasm contract actions)

Common Message Types

`@type`	Description
`/cosmos.bank.v1beta1.MsgSend`	Native token transfer
`/cosmos.staking.v1beta1.MsgDelegate`	Stake tokens with a validator
`/cosmwasm.wasm.v1.MsgExecuteContract`	Execute a smart contract (swaps, buys, etc.)
`/cosmwasm.wasm.v1.MsgInstantiateContract`	Create a new contract instance
`/xyz.bridge.v1.MsgBurnForBridgeOut`	Withdraw XYZ to Solana

Search Transactions

Search for transactions matching event filters. At least one filter is required.

By Sender

curl "http://67.205.164.156:1317/cosmos/tx/v1beta1/txs?events=message.sender='xyz1sender...'&order_by=ORDER_BY_DESC&pagination.limit=20"

By Recipient

curl "http://67.205.164.156:1317/cosmos/tx/v1beta1/txs?events=transfer.recipient='xyz1recipient...'&order_by=ORDER_BY_DESC&pagination.limit=20"

By Block Height

curl "http://67.205.164.156:1317/cosmos/tx/v1beta1/txs?events=tx.height=152340&order_by=ORDER_BY_ASC"

By Message Type

curl "http://67.205.164.156:1317/cosmos/tx/v1beta1/txs?events=message.action='/cosmwasm.wasm.v1.MsgExecuteContract'&pagination.limit=10"

Search Response

{
  "txs": [...],
  "tx_responses": [
    {
      "height": "152340",
      "txhash": "A1B2C3...",
      "code": 0,
      "gas_used": "150000",
      "timestamp": "2026-02-19T10:00:00Z"
    }
  ],
  "pagination": {
    "next_key": "base64-cursor...",
    "total": "42"
  }
}

Broadcast Transaction

Submit a signed transaction to the network.

curl -X POST http://67.205.164.156:1317/cosmos/tx/v1beta1/txs \
  -H "Content-Type: application/json" \
  -d '{
    "tx_bytes": "base64-encoded-signed-tx",
    "mode": "BROADCAST_MODE_SYNC"
  }'

Broadcast Modes

Mode	Behavior
`BROADCAST_MODE_SYNC`	Wait for CheckTx validation, then return. Recommended for production.
`BROADCAST_MODE_ASYNC`	Return immediately without validation.

Simulate Transaction

Estimate gas for a transaction without broadcasting it.

curl -X POST http://67.205.164.156:1317/cosmos/tx/v1beta1/simulate \
  -H "Content-Type: application/json" \
  -d '{
    "tx_bytes": "base64-encoded-tx"
  }'

Returns the estimated gas_used which you can multiply by 1.3-1.5 for a safe gas_limit.
