AVAX -> SUI w/o automatic relay

Don’t have allowances to spend the wrapped SOL?

Ok, so the error about the allowance comes from it trying to test run the transaction to get a gas estimation. If this happens, it falls back on a default value. I'm not sure why the transaction reverted though

@tsadovska we could not reproduce this after trying a few times. Do you mind retrying on mainnet with the new build and closing if you can't repro? Thanks!

[tsadovska]

Rechecked the issue with the similar scenario on https://wormhole-connect.netlify.app/ [Testnet] and https://mainnet--wormhole-connect.netlify.app/ [Mainnet].

• https://mainnet--wormhole-connect.netlify.app/ [Mainnet] - Tested NOK when sending 0.001 WFTM from Avalanche to Moonbeam. Transaction fails with error "transaction may fail or may require manual gas limit" (ticket: #780)

[tsadovska]

Error "ERC20: transfer amount exceeds allowance" appears in Console when sending asset for the first time. Please view observations in ticket #798.

Ticket is closed.
