1. Transaction Export (aura export)

Export your complete on-chain transaction history to CSV or JSON — fully compatible with Koinly, CoinTracker, TaxBit, and CryptoTaxCalc. Fetches both native and ERC-20 transfers, deduplicates, and sorts chronologically.

❯ aura export 0xd8dA6BF...
Fetching transactions...
Processing 1,247 transactions...
✓ Export Complete
File: aura-export-d8dA6BF-Ethereum-2026-03-14.csv
Records: 1,106 | Sends: 423 | Receives: 680
  • ✓ Supports CSV and JSON formats (--format)
  • ✓ Custom output directory (--output ./reports)
  • ✓ Works on ETH, Polygon, Base, Arbitrum, Optimism, BSC

2. Liquid Staking (aura stake)

Stake ETH into Lido (stETH ~3.8% APR) or Rocket Pool (rETH ~3.6% APR) directly from your vault-secured CLI. Preview stakes before confirming, check existing positions with --info.

❯ aura stake 0.5 lido
Protocol: Lido
Stake: 0.5 ETH → ~0.5 stETH
Est APR: 3.8% (~0.0190 ETH/year)

3. P&L Tracker (aura pnl)

Calculate on-chain profit & loss by walking transaction history. See total invested, current portfolio value, unrealized gains/losses, and overall ROI for any wallet address.

❯ aura pnl 0xd8dA6BF...
P&L Summary

Current: 15.82 ETH
Gain: +3.42 ETH (+27.6% ROI)

4. Multicall Batching (aura multicall)

Execute multiple smart contract read calls in a single RPC request using the Multicall3 standard, drastically reducing latency for multi-data queries.

❯ aura multicall 0xContract... balanceOf totalSupply decimals
3 calls batched → 1 RPC request
✓ Results returned in 120ms

5. Calldata Decoder (aura decode)

Decode raw transaction calldata into human-readable function calls and arguments using Etherscan ABI sources or a local ABI file.

❯ aura decode 0xa9059cbb0000000000000000000000...
Function: transfer(address to, uint256 amount)
to: 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
amount: 1000000000 (1000 USDC)

6. Event Log Viewer (aura logs)

Fetch and display on-chain event logs for any contract. Filter by event signature, block range, or specific topics for precise forensic inspection.

❯ aura logs 0xA0b86991... --event Transfer
Found 48 Transfer events in last 1000 blocks
[Block 19443210] Transfer 50,000 USDC → 0x742d...
