CHAIN
Check balances and decode transactions on Optimism from the command line
Everything glnc can do on Optimism: balance lookup, transaction decoding, and live gas. Examples below are copy-pasteable; swap the address or hash for your own.
Quick install
On macOS or Linux:
brew install aryarahimi1/glnc/glncglnc 1.0.9 ready · Optimism support built in
Balance on Optimism
glnc auto-detects Optimism from the address format. To restrict a multi-chain query to Optimism only, pass --chain op.
glnc balance 0x... --chain optimism ⬢ OPTIMISM (14 tokens)
ETH 0.420 $1,364.20
OP 230.00 $483.00
USDC 6,420.12 $6,420.12

Grand Total $8,267.32
Decode a Optimism transaction
Pass a hash and (optionally) --chain op to skip cross-chain probing. glnc decodes calldata and walks token movements out of the receipt logs.
glnc tx 0xabc... --chain optimism ✓ ERC-20 transfer on ⬢ OPTIMISM
