Description

Multi-hop swaps via the router fail with out of gas. The SWAP_GAS_LIMIT (600000) is sufficient for single-pair swaps but not for multi-hop routes.

Error

out of gas in location: wasm contract; gasWanted: 600000, gasUsed: 601616: out of gas

Route Tested

EMBER → JADE → TOPAZ (2-hop route)

Expected

Gas limit should scale based on number of hops. Suggest 600k per hop (e.g. 2 hops = 1200k).

Steps to Reproduce

Connect wallet
Select EMBER as From, TOPAZ as To
Route shows EMBER → JADE → TOPAZ
Enter 10 EMBER, set slippage to 5%
Click Swap — fails with out of gas

Notes

Single-pair swaps work fine at 600k. This is a new issue since the router was just implemented.
