Bash script that exercises a full trading workflow: - Deposit USDC from Base → Hyperliquid - Quote and buy SILVER perp, monitor price for up to 10 min - Sell SILVER perp when price rises above entry (or on timeout) - Withdraw USDC back to Base - Buy ETH spot on Hyperliquid, withdraw to Ethereum mainnet - Buy TSLA on Coinbase Requires funded wallet with >= $10 USDC on Base and Coinbase keys.

Add informative before/after messages for each step showing key JSON response data — prices, funding rates, position sizes, PnL estimates, bridge TX hashes, and color-coded price monitoring output.

Replace run_fintool() || true pattern that silently swallowed all errors. New approach captures stdout/stderr/exit-code separately via temp files. check_fail() helper prints the full error output (colored red) and calls fail() whenever a command returns non-zero. Each step now: - Gates on prior step success (e.g., skip sell if buy failed) - Prints fintool's stderr progress messages in gray on success, red on failure - Shows the exact error text from fintool on failure - Tracks pass/fail counts accurately in the summary Signed-off-by: Michael Yuan <michael@secondstate.io> Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Deposit is a prerequisite for all subsequent trading steps. Stop immediately instead of continuing with steps that are guaranteed to fail. Signed-off-by: Michael Yuan <michael@secondstate.io> Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Before executing the USDC bridge, check ETH balances on both the source chain and Arbitrum. If Arbitrum has insufficient ETH for the final HL Bridge2 deposit tx, automatically bridge 0.001 ETH from the source chain via Across Protocol. Bail early with a clear error if the source chain lacks enough ETH to cover gas + the ETH bridge amount.

Use 0x0 as outputToken in the Across API to receive native ETH on Arbitrum instead of WETH. This avoids the chicken-and-egg problem where unwrapping WETH requires native ETH for gas but there is none. Flow: wrap ETH→WETH on Base → Across bridge → native ETH on Arbitrum. Also removes the WETH balance check and unwrap logic that is no longer needed. Signed-off-by: Michael Yuan <michael@secondstate.io> Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
