TIP

In order to bridge out of Flame on Mainnet you must have a balance of native funds to pay for gas. This is the transfer/channel-0/utia bridged from Celestia.

To make the following commands easy to copy and paste, export the RPC_URL:

bash
export RPC_URL="https://rpc.flame.astria.org"

To Astria ​

INFO

Make sure the ORIGIN_DESTINATION_CHAIN_ADDRESS in your .env file is updated to be the address of the desired asset you are withdrawing:

  • Set to your Celestia address to withdraw TIA
  • Set to your Noble address to withdraw USDC
  • Set to your Osmosis address to withdraw milkTIA
  • Set to your Stride address to withdraw stTIA

Then run the following command:

bash
forge script script/AstriaWithdrawer.s.sol:AstriaWithdrawerScript \
   --rpc-url $RPC_URL --broadcast --sig "withdrawToSequencer()" -vvvv

To IBC Chain ​

INFO

Make sure the ORIGIN_DESTINATION_CHAIN_ADDRESS in your .env file is updated to be the address of the desired asset you are withdrawing:

  • Set to your Celestia address to withdraw TIA
  • Set to your Noble address to withdraw USDC
  • Set to your Osmosis address to withdraw milkTIA
  • Set to your Stride address to withdraw stTIA

Then run the following command:

bash
forge script script/AstriaWithdrawer.s.sol:AstriaWithdrawerScript \
   --rpc-url $RPC_URL --broadcast --sig "withdrawToIbcChain()" -vvvv

View Transactions on Astrotrek ​

Go to https://astrotrek.io/account/<your-astria-account>?tab=transactions to see the withdrawal transactions. You can also search the returned transaction hash directly in Astrotrek.

View Transactions on Mintscan ​

If you bridge out to an IBC chain, you can view your transactions by visiting the following:

  • https://www.mintscan.io/celestia/address/<your-celestia-address>
  • https://www.mintscan.io/noble/address/<your-noble-address>
  • https://www.mintscan.io/osmosis/address/<your-osmosis-address>
  • https://www.mintscan.io/stride/address/<your-stride-address>

You can also go directly to Mintscan and search for the txhash that is returned after sending your transaction, but it is recommended to view your address transaction history as this will show if an acknowledgement for your transfer was received.
